I've been having some issues with my PC doing random reboots.

What's happened so far:

About a week ago my PC started to do random reboots. I took it in to a local PC shop to get it dusted cause I thought it was overheating. This has happened in the past and by getting a good dusting, it did fix the issue.

But even after that, the random reboots continued. A friend of mine who is a PC technician attempted to fix it with no success. He did various software and hardware checks. Not sure what.

Decided to reformat and reinstall Windows XP and a handful of software I use on a daily basis. Random reboots continued.

Took it in to the shop I bought it from and the technicians there could not pinpoint the problem was either.

Random reboots occur when:

I go into folders with movies or images, the PC will reboot instantly. If I view these folders in List, no reboots. Only in Thumbnail. Read this on another forum. But it's only a temporary fix.

All other reboots are random.

And today I finally get a blue screen after a random reboot.

This is the error message:

Bad_Pool_Caller
STOP: 0X000000C2(0X00000007, 0X00000XD4, 0X04100808, OXE1987988)

I read on an older post when someone asked to attach the minidump.dmp file for a closer inspection. I have attached the latest minidump file.

Does anyone know how to fix this issue?

Thanks in advance.

Please provide the system details by following this link and put the results in your next post. Go here

Follow this guide to test the memory.

Preliminary checks
You should first check the model of RAM stick that you have on the manufacturers site for the recommended voltage setting and then make sure it is set correctly in the PC's Bios. An incorrect voltage setting may be the reason for your problems so test the PC's performance again if the voltage was incorrect.
Errors can also be caused by dirty contacts, mismatched sticks or using them in the wrong slots. Check all sticks are the same make and specification, check the motherboard manual for the correct slots to use. Remove all the sticks and clean the contacts with a soft pencil eraser and blow out the slots with a can of compressed air.
Download Memtest86+ from here
When the download is complete right click the file and select Extract Here and burn the image to a CD.
In windows 7 right click the extracted file, select Open With, then select Windows Disc Image Burning Tool then follow the prompts. For all other versions of windows (if you do not have an ISO burner) download this free software. ImgBurn
Install the program and start the application. Select the top left hand option to burn image file to disk and then on the next window click on the small yellow folder icon and browse to the ISO file you have downloaded. Then click on the two grey discs with the arrow in between (bottom left) and leave it to complete the operation.
Testing
Boot the PC into the Bios setup and set the CD/DVD drive to 1st in the boot sequence. Insert the disk in the drive then reboot and the disc will load into dos. Leave the test to run through at least 8 cycles or until it is showing some errors. If errors show in the test, remove all but one of your RAM sticks and repeat the test on each stick until you find the one that is faulty. This is a long slow test and should ideally be run overnight.
The memtest will not be 100% accurate but should easily detect any major faults.
IMPORTANT
Always disconnect your PC from the mains supply when removing Ram sticks and earth your hands to discharge any static electricity to avoid damage to sensitive components. If performing this test on a laptop PC you should also remove the battery before removing or replacing the RAM sticks.

Here's my PC specs:

Is this a high probability that it's a Ram issue?

This will be a process of elimination, but RAM is the prime suspect and after having done a reinstall with no change to the problem it will without doubt be an item of hardware.

Please state if this is a laptop or desktop PC.

It's a PC. Various other test have been done by another technician. One was replacing existing Ram with a new one and also changing the video card. But it still crashes. Next suspect was the motherboard.

Mini dump file shows - memory corruption.
Run the Mem Test suggested - remove all Ram sticks and test each stick on its own.

While you have your RAM removed please post the make and model number that is written on both of the sticks.

I asked if your PC was a laptop or desktop and you replied "it's a PC". PC stands for Personal Computer so that does not tell me the answer. As you have now said the graphics card was replaced I know it's a desktop PC :).
