I have a randon BSOD crash problem that is driving me mad, I hope you can help.
My PC is a self build with the components in the Jpegs above. The case is a CoolerMaster HAF and the powersupply is a modular 900w.
The BSODs occur at apparently random intervals and the system can be fine for days with no problems. the BSODs occur even when the PC is idle, having just booted up and no user activity has taken place.
The most recent crash was typical; the pc was switched on and left to start up, windows loaded and was idle, the PC BSOD'd and restarted, then BSOD'd again, eventually windows start up repair kicked in and was unable to repair. I switched off PC (no power) switched it back on again and windows loaded fine (although when this happens I have to tell Avira Firewall what applications it can trust again - not sure if that is a red herring).
I have asked a local supplier to analyse the PC for faults (Novatech - charged for of course) they had it for a week and could find nothing saying it did not crash). It sometimes does not crash for several weeks!
Things I have tried;
- I have swapped the Graphics card (was an ATI 5870, now is an nvidia GTX570)
- I ran memtest86 for 15 hours and it did not detect any errors.
- I ran a similar test for the graphics card memory for 6-7 hours and again no errors were found.
- I changed from AVG2011 to Avira in case it was that.
I would be very grateful if someone could take a look and give me a pointer as to what to try next.
