Need help with bsods

[Martin Einarsen]

Hey!

I bought a new pc with w8 pre-instaled. My system specs is:
Asus p8z77 v pro
3570k@4.6 with noctua nh-d14
Gainward gtx 670
Kingston DDR3 HyperX blu 1600MHz 16GB
Cruical m4 ssd
seagate barracuda hdd

I didnt have much problem the first month, but later I started getting more and more bsods. Some times I get every 20 mins or so.
I thought I fixed it last night by running check disk on next restart, and doing a full scan in safemode with diffrent programs.

I have had these bsods:
Critical structure corruption. I had this one right before I am writing this.
Driver irql not less or equal (nvlddmkm.sys). I believe this was fixed with updating gfx card driver.
Clock Watchdog Timeout

I have looked in decive manager and I have not found any questions marks or anything similar.

Anyone have any ideas how to troubleshoot ?

Based on those error codes, I would start by testing your RAM using MemTest86+.

Alright I did the memtest86 and I got no erros when the test was completed.

How long did you leave it running? I should have specified in my initial reply to leave it running for an extended period... like starting it before you go to sleep and leaving it running overnight.

I let it run for about 20-30 mins I think. I just stopped once it said it was done and said it didnt find any errors. But I can start it now and let it run while I'm at work.

Alright, I have let it run for quite a while now and still no errors.
