System Crashing

kirkbd99 · 13 Apr 2011

Hi I am having problems with my system constantly crashing.

PC Intel Q6600 quad
2 gig OZC Reaper 8500 (4) running with 2 slots filled currently
GA-EP45-UDR3 Mother Board
650 Watt power supply (also swapped 750 watt power supply)
ATI 5750 video - with most uptodate video driver from ATI site (Swapped with NVidia GTX 460 with most recent video drived from Nvidia site)
Running raid -1 with 2 - 150 gig WD rapters
1 WD blue 1 Tb disk
1 Segate 250 Gb disk
OS Windows 7 Home Premium 64bit

I have run Memtest86 and Windows Memory diagnostics multiple times - neither are reporting any memory errors.
I have swapped out the power supply No change in behaviour
I have swapped out the two video cards and corresponding vendor drivers - no difference.
I have wiped and reinstalled Windows 7.
The vaious disk checkers I run report no problems with any of the disks.

Have verified that I am not over-clocking the CPU or the memory.

Behaviour - will boot windows 7 and login.
If I start to play a video game, the client stops responding shortly after starting
the game. I can get to the task manager but it shows that the client has stopped responding. (This is a game I have been playing for a couple of years on this same rig).
If I send the information to Microsoft it does not come back with any suggestions or solutions.
Other times I will get a BSOD and a mini dump.
When I run the Windows Debuger it is informing me that different drivers are the culprit.
Once DX driver relates, another the ntkernel, and another a system service driver.

History:
About two months ago I noticed that my PC would hard hang periodicly. I troubleshooted this to the CPU overheating. When I removed the CPU cooler I found that the thermal liquid silver was dried out (been in place for three years). I replaced the stock cooler with Zalman CNPS9900LED Ultra Quiet CPU Cooler, I first cleaned the old artic silver off of the cpu using ArctiClean 60ml Kit (includes 30ml ArctiClean 1 and 30ml ArctiClean 2) and 3.5grams Arctic Silver 5 Thermal Compound.
Once cleaned I applied new Arctic Silver and mounted the new CPU cooler.

Since then the CPU has never gone above 45 Celcius

Over time the problem of Hard hangs and BOSD have increased in frequency get worse and worse till I am at the point where the PC is unusable.

At this point I am going to try and replace the current mother board with an old Asus mother board that I have.

I am not sure where to go from here with the problem?

At this point I left with thinking it is either the Motherboard or the CPU. When I have run benchmarking software against the CPU I have no problem the benchmark completes without any issues.

So my question is if I replace the motherboard and the problem persists is there something I have missed in try to resolve the issue?

Thanks

Hello,

I'd say the problem is down to RAM, CPU, and motherboard. If you can test that other motherboard, that would be great. CPU failure isn't real common, but it does happen. On the other hand, RAM failure is relatively common, and software tests don't always pick up on it.

It seems your motherboard is fairly picky about which RAM it accept; is your current RAM DDR2 1066 MHz? If not, I suggest you purchase some that meets or exceeds that number.
