Why Computer Makes Weird Noises

If your computer makes weird noises, then you’re having a hardware issue of some type, which means you’ll probably need to open the case to determine what’s causing the noise. There are only a few components in the computer that move, so unless the noise is a beep, then there is likely an issue with a drive or a fan. If you are not comfortable opening the computer case while the computer is running, be sure to take it to a computer repair shop so they can help find the cause.

Noises From Inside The Computer

The components that can generate noise in the PC are the fans (there could be several), CD or DVD drive, Floppy drive, hard drive and power supply. You should start by ejecting any disks that might be inside of any of the drives, such as the floppy, Zip drive or CD drive. If there are no disks, and no activity lights on those devices, then it is likely one of the following:

CPU FAN NOISES


You have at least one, but probably as many as three or four fans inside of your computer. You are guaranteed to have a fan in the Power supply. The power supply is at the back of the computer and has an exhaust fan. Some power supplies have another fan inside that draws air upward from the CPU so the exhaust fan can pull the heat out of the case.

You probably also have a fan on the CPU. The CPU fan will rest atop a metal heat sink. This fan is responsible for pulling the heat away from the CPU to keep it cool.

There could be intake fans in the front of the case and exhaust fans going out the back.

There could also be a fan on the video card GPU, which is similar to the CPU fan, but smaller.

A couple of things can happen with fans. They can simply be dirty and need to be blown out with compressed air. Or the bearings in them are starting to fail. If it is the latter, you will need to replace the fan. If the case is open, you can usually quickly pinpoint the fan that is causing the issue. If compressed air does not fix a noisy power supply fan, replace the entire power supply immediately.

Noises From The Power Supply

The power supply can have a couple of noises. It could have a bad or dirty fan as described above, or it can be making an electrical humming noise. If blowing the fan out does not help, or if you do hear the electrical hum, unplug the computer and replace the power supply immediately.

Noises From The Hard Drive

It’s not unusual for the hard drive to churn and hum as it works. If you notice loud noises above that, a few things can be happening. There could be physical defects on the platters, causing the high-speed head to bounce. It could have a bad actuator arm or read / write head. Both of these necessitate an immediate replacement of the drive. Or it could just be struggling to read and write due to a lack of space or maintenance. Check the remaining capacity and remove anything you can if the space is low. Then defrag the drive by going to Start>All Programs>Accessories>System Tools>Drive Defragmenter.

You might also want to run the Disk Checking Utility. This will scan for physical defects on the drive and mark them as non-usable. To do this, right-click the C Drive in My Computer and select Properties. Under the Tools tab, click the Check Now button and have it scan and fix any errors it finds.

In conclusion, the power supply is not serviceable. Any noise coming from there is bad news and the power supply should be replace. All other fans–even the video card fan–can be replaced, if necessary. If the hard drive is making noises, back up all data, remove what you can and run the disk defragmenter and disk checking utility.

How To Fix Your Printer

If this is a new cartridge, open the front cover and remove all cartridges. Be sure the protective film has been removed from the cartridge prior to installation. Inspect the contacts on the new cartridge for damage. Replace the cartridges in the correct place, close the front cover and power the printer down and then up again.

Printer Cannot Be Installed

If you’re trying to install a printer and it will not install, be sure to check the Device Manager in the Control Panel for any Unknown Devices. Your printer will be come an Unknown Device if you plug the cable in before installing the driver software. Remove the Unknown Device and then unplug the USB cable. Next, install the software that came with the printer, and when finished, plug the USB cable back in.

Printer Streaks

If your printer is producing a streaked image, you will need to clean the printer heads. To do this, go to Printers in the Control Panel, then right click your Printer then select Properties. A menu with the various settings will appear. You need to select Clean Printer Cartridges. The printer will run in cleaning mode.

Printer Does Not Print Jobs

When you click Print and nothing happens, you may be sending jobs to a printer that is not connected to your computer. For example, if another printer was previously installed, and you install a new printer, the old printer might still be setup as the Default Printer. Go into the Control Panel, then Printers and make sure the new printer is set to Default.

Printer Jams Frequently

If your printer jams frequently, you may be loading too much paper. This can also occur if you’ve had jams in the past and have a piece of debris still stuck in the printer. Use a flashlight to examine the entire mechanism to ensure no paper is still inside. This can also happen if an internal gear is damaged. You will often notice one side being fed faster than the other. This could me the printer is physically damaged and needs to be replaced or repaired.

How to Fix A Dead Computer

One of the most difficult computer problems for a home user is troubleshooting a dead computer. When we mean “dead” we mean no signs of life at all. Where do you even begin? The average user doesn’t know the internal workings of their computer–and they shouldn’t have to. So when things go wrong, they do not know where to begin to diagnose and either fix the problem or make arrangements to have the problem corrected. The following steps will help give you some general knowledge of what could be wrong with your PC and give you some ideas on how to fix it or provide you with enough knowledge to prevent you getting ripped off at the computer repair shop.



For starters, if the computer is still under warranty, do not open the case, as this will void your warranty. HP, Dell and any other major manufacturer will respond quickly to your problems and arrange for you to send the computer in, or they might opt to send a technician out to work on the computer. If you bought the PC at a shop around the corner, send emails and begin a paper trail on the issue.

With that said, a completely dead computer will usually have either a bad motherboard, bad power supply, or a faulty case. The following steps will help you find out which is the culprit. Well start with the easiest and work our way down to the hardest. One of the first things you’ll want to do is unplug the computer and take it to a table where you can lay it flat. Open the case and check the connections to see if you notice anything blatantly wrong, then proceed with the steps below.

Diagnosing A Bad Power Supply

Power supplies can fail without warning. The worse part is, they can partially fail. This means you might be getting power to the motherboard, the fans and other components, but you do not have the correct voltages to start the motherboard.The power supply is located at the back of the case, and is where the power cable plugs into the PC.

1. Your first step should be to plug the computer directly into the wall and bypass any power strips. You should also confirm the outlet is working properly.

2. Make sure the red voltage regulator switch on the back is set to 115 if you reside in the United States, people in some countries will need to set theirs to 230. With the power off and unplugged, try toggling the switch to 230, then back to 115 to make sure it is seated in the right position.

3. Next, buy a power supply tester. Computer techs will use a multimeter to test for proper voltages. Normal users can just buy a power supply tester. These are cheap and easy to use.

4. If your power supply is bad, buy one of equal or greater power. If your current power supply is 350WT, be sure to get one that’s 350WT or higher. Shop for a power supply.

5. If you have an HP computer, read these HP power Supply troubleshooting tips.

A power supply will tend to fail before anything else, as they take the most abuse. They are the front line when a power surge or brown out occurs. The good news is, they are extremely easy to replace should you find this is the problem.

Diagnosing A Bad Computer Case

While a dead PC will either normally be a bad power supply or bad motherboard, the next easiest thing to troubleshoot is the case. How can a case go bad? A case has minimal smarts, but it does have wires leading from the power button to the motherboard that can go bad, and some even have advanced I/O panels that can fail.

1. You can try bypassing the case switch. This means you are initiating the power-on sequence without using the button on the front of the case. For this, you will need a good set of eyes and a small, flat-head screw driver. The idea is to find the wire leading from the power button to the motherboard that’s marked something like POWER SW or POWER ON. It will cover two pins on the motherboard. Carefully, with the computer plugged in, touch tip of the flat head screwdriver to both of those pins at the same time, thus “shorting” them. You will not get shocked by doing this, but you need to be careful not to scratch the motherboard. Read more on bypassing the case switch here.

2. If you have a Dell computer, read how to test a Dell I/O panel here.

Diagnosing A Bad Motherboard

The motherboard is the hardest thing to diagnose and replace. If your motherboard is proven to be bad, it must be removed from the case and replaced. Unfortunately, there’s a lot of stuff plugged into the motherboard, such as the CPU, RAM, PCI cards, Video Cards, hard drives, CD / DVD drives, power supply and fans. There are also tricky connections that must be made to the case’s power and reset switches. So replacing a bad motherboard is a long process. A bad motherboard will be determined by the following:

1. If all of the above are not the problem, the motherboard is the problem by default.

2. A bad motherboard might have visual signs of damage, such as bulging or leaking capacitors. See below.

3. With the computer unplugged, try holding in on the power button for twenty seconds. This will drain the capacitors of any excess power. The computer might start up and work fine forever. If the computer starts, then fails again after doing this, then the motherboard is bad.

4. Try removing any non-essential cards and drives in the computer. You do not need modems, sound cards, hard drives, CD / DVD drives, or floppy drives connected to boot. Our goal is to get a clean power-up situation, not boot into windows. If you remove non-essential parts and you still have no power, then the motherboard is bad.

In Conclusion, technicians will have more advanced tools and diagnostic equipment to quickly find the problem with your PC. But it will usually be one of the above that is causing the problem in a no power scenario.

And at the last : Check memory modules, & swap out to known working memory also.

Good Luck ...

How to fix MBR in Windows XP and Vista

What is the MBR? MBR stands for Master Boot Record and it’s the first sector of your hard drive that basically tells the BIOS where to look for the operating system on your computer.

If, for any reason, the MBR becomes damaged or corrupt, then the operating system will be unable to load. You will normally see error messages like:


" Error loading operating system "

" Missing operating system "

" Invalid partition table "

These messages are definitely not fun, especially if you are not familiar with computers. Most people would automatically assume their computers are dead! However, that’s not true. Being in IT myself, these errors are actually preferably to other types of Windows errors. Why?

Well, it’s actually fairly easy to fix the Master Boot Record in XP and Vista. All you have to do is load up the Recovery Console and run a simple command. All of your data, applications, settings, etc are still intact on the drive and once the MBR is fixed, the computer will load normally.

So how can you repair your damaged MBR? Here are the steps to follow:

1. First, restart your computer with the Windows XP setup disk in the CD drive. If you don’t have your original disk, borrow one or download a ISO image from a torrent site.

2. When prompted, boot from the CD drive by pressing any key. If Windows loads automatically, you will first have to enter the BIOS setup and change the order of the boot devices to start with the CD drive.

3. Once the setup loads, you will see the option to press R to repair a Windows installation.

4. Once the Recovery Console loads up, you will have to type in a number that corresponds to your Windows installation. This is normally just 1. Press Enter and then type in the Administrator password.

5. Now at the prompt, type in fixmbr. Your damaged MBR will now be replaced with a new master boot record and your computer should now be able to boot properly. Note that you may also want to run the fixboot command to repair the boot sector with a new one.

Also, make sure you only use these commands on a system with one operating system installed. If you have more than one operating system installed, fixmbr and fixboot could mess up everything.
Fix MBR in Vista

In Vista, the procedure to fix the master boot record is a bit different. You have to start up Vista in the Recovery Environment and then run the bootrec command. Here’s how.

1. First, load up the Windows Vista disc in your drive and press any key to boot from the disc.

2. Choose the language, time, currency, etc and click Next. Now click on Repair Your Computer.

3. Choose the operating system to repair and click Next. When the System Recovery Options dialog comes up, choose the Command Prompt.

4. Now type bootrec.exe and press Enter. This will rebuild the boot configuration data and hopefully fix your problem. You can also run the command with switches to fix just the master boot record (/fixmbr), the boot sector (/fixboot), or rebuild the entire BCD (/rebuildbcd).

Good Luck...
