Windows 7: Self-built desktop keeps crashing

Self-built desktop keeps crashing

Hello, I just joined this forum and this is my first time posting.
I built my desktop in late December last year. Everything seemed fine until I installed Windows 7 Ultimate x64 (Korean) and started installing programs I regularly use. Then, BSOD hit me...I'd never had a self-built computer crash on me so fast after building, and I thought it might be a problem with Win7 installation, so I tried formatting and re-installing windows multiple times (probably 5~6 times), but BSOD kept happening. Win7 even refused to be installed at all twice or so.

I have been really busy with work since, so I just never got around to try fixing it until last week. I did a fresh installation, then everything seemed fine until two nights ago, when my computer failed to boot up. I get the usual bios messages, and even the windows logo that shows up before the mouse pointer appears, then BSOD. It happens every time I try to boot up. I managed to pull out minidumps, so I'm attaching them here.

It seems to me like a hardware problem. I have run windows' memory diagnostic tool, which told me there aren't any problems with my memory, but who knows. My amateur guess for the culprit is the motherboard, but I wanted to ask for professional opinions here and decide which components I should send in for after-service.

Thanks in advance!

oops I forgot to post my system specs and minidumps
Here they are.

Motherboard: ASUS P7P55D
CPU: Intel i7-860 Lynnfield
RAM: EKMEMORY DDR3 8G (4x2G) PC3-12800

I have examined your dump reports. Based upon my analysis you had 3 BSOD's recently.
The last Dump report was corrupted and I was not able to read or open it.

The other two reports indicated stop errors of 00000005 and 1000007E. Based upon those reports and the additional information contained in the files the following information was ascertained.

You have a corrupted driver which must be replaced, the ATI radeon Kernal Mode Driver

In addition memory problems were evident. You should download and use memtest86 to test the memory.

You should also check for any corruption by perfoming a System File Check.
On an elevated command prompt (type cmd in search, right click and then run as administrator) type the letters sfc /scannow.

It is often the case that after these repairs are made additional BSOD may occur, especially since I could not read the last report. If that occurs return and we will report the additional problems to you.

There is also an idication that csrss.exe was involved. This is a normal process but sometimes the hiding place of a virus. So perform a virus scan.

One of the reports mentioned pool corruption which points to memory. The problems could be many but one possiblity is mismatched ram. Since your compter is self built this is a potential problem. So be sure to perform the previoulsy mentioned memory test.

I agree with Richard. Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder. Boot from the CD, and leave it running for at least 5 passes.

Try this free stress test: Free Software - GIMPS
Prime95 Setup:
- extract the contents of the zip file to a location of your choice
- double click on the executable file
- select "Just stress testing"
- select the "Blend" test. If you've already run MemTest overnight you may want to run the "Small FFTs" test instead.
- "Number of torture test threads to run" should equal the number of CPU's times 2 (if you're using hyperthreading).
The easiest way to figure this out is to go to Task Manager...Performance tab - and see the number of boxes under CPU Usage History
Then run the test for 6 to 24 hours - or until you get errors (whichever comes first).
The Test selection box and the stress.txt file describes what components that the program stresses.
Try this free video stress test: FurMark: Graphics Card Stability and Stress Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net
FurMark Setup:
- If you have more than one GPU, select Multi-GPU during setup
- In the Run mode box, select "Stability Test" and "Log GPU Temperature"
Click "Go" to start the test
- Run the test until the GPU temperature maxes out - or until you start having problems (whichever comes first).
- Click "Quit" to exit
Test your hard drive as well: HD Diagnostic
