Windows 7: BSOD 0x1a_41790

Hi

My PC is giving BSOD quite often, often at just after logging to windows, and I could not find anything about the bugcheck 0x1a_41790 which is seems to be the cause of these latest crashes. I have waited long before starting to fix the problem as I needed the computer back then, but now I have time to try to fix it.

System:
Chip: Intel i7 920
Mobo: Asus P6T SE
RAM: Corsair CM3x2GB1600C9 (only using 2 sticks as one is certainly damaged)
Graphics: Asus 5770
HD: Samsung HD502HJ
PSU: Antec CP-850
Case: Antec P183

System builded in Dec 2009, OS is OEM Windows 7 Home Premium 64bit.

I'm going to RMA the RAM as one of them is broken, but the memtest does not find anything on the remaining ones, which have been the only RAM since beginning of October, and the system is still crashing. Do you have any ideas what else might be wrong?

Since Avast was running at the time of several of the most recent crashes I would

1-remove avast and replace it with Microsoft Security Essentials and the win 7 firewall

2-re-run memtest for at least 6-7 passes one stick at a time.

Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Boot from the CD, and leave it running for at least 5 or 6 passes.


Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot. Test the sticks individually, and if you find a good one, test it in all slots.

3-run a system file check

SFC /SCANNOW Command - System File Checker
