Hello I am new to the site and I am already causing problems, sorry.

I am running Windows XP SP 2. My PC crashes when ever I am on for 1 hour or longer or when I try playing Call Of Duty 4. Since I could remember I always had issues with my computer, I had it for over 2 months. I reformatted it 3 times now. My friend built it for me but then a professional took a look at it and he said it should be fixed, but he did not fix it.I have CA Internet Security Suite Plus 2008 protecting my PC.

My Specs are:

e-GeForce 8800 GT (Video Card)
Liteon 20x SATA DVD Writer (DVD Driver)
ULTRA LSP 750 Watt ATX (Power Supply)
WD Caviar 500GB Serial ATA HD (Hard Drive)
Intel Duo Core Processor 2.66GHz (CPU)
nFORCE 680i LT SLI (Motherboard)
4 GB OCZ (Ram)
(Some CPU cooler and a case fan as well)

I was reading some forums that my Video Card could be faulty.
I am able to buy what ever I should buy.

My PC just crashed on me I got the blue screen of "Death" and it said "ERNEL_STACK_INPAGE_ERROR" I know that there is a letter before the ERNEL.
It also said "0x0000007A(0xE252A6B8, 0xC0000185, 0xBF8CE97D, 0x3FBA6800)

Win32K.sys - Address

BF8CE97D base at BF80000000 Date Stamp 47e0e106"

Hey Alex, welcome to PCHF.

Could be overheating there would be my first thought. Can you check your temperatures using:

Use nTune for your graphics card: NVIDIA nTune
Speedfan for the rest of your PC: SpeedFan - Access temperature sensor in your computer

Can I confirm that when you say that the PC crashes, the screen actually freezes?

EDIT: Can you follow the BSOD link on my signature, and post a couple of logs on your last 2-3 if possible.

Yes the screen does freeze.
What do you mean "Post a a couple of logs on your last 2-3 if possible"?

If you follow the link Alex, it describes how to post a log of your last Blue Screen of Death. If you have received more than one, then please post a couple, as it will help to narrow your problem down further. Also don't forget your temperature checks.

Sorry it took long for me to reply my PC crashed.

I am having trouble finding out how to find the temp of my PC.
And I don't understand this "How to Attach a Dump File in PCHF

Sorry, can you tell me exactly which part are your stuck on?
