ntoskrnl.exe BSOD

[Poonagez]

Well I keep getting this ntoskrnl.exe BSOD at random times. I've googled it and there seems to be many reasons to why it could happen. It says it could be a bad RAM but i've ran the memtest and recieved no errors. I've also tried to reinstall my OS. The only thing i changed in BIOS was voltage to 2.00 and to 4-4-4-12. Anybody have any suggestions?

Specs are:
GIGABYTE GA-EP45-UD3R
G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500)
Intel Core 2 Duo E8400
Thermaltake Purepower W0100RU 500W
SAPPHIRE 100245L Radeon HD 4850

Re: ntoskrnl.exe BSOD

Well for 2x2GB you may need to adjust your MCH Voltage. What Memtest did you use, and for how long?

I would advise you use this Memtest86+ latest version and run for at least 5 full passes or overnight while you sleep >>>
Memtest86+ - Advanced Memory Diagnostic Tool

I suggest 1.20-1.24 for MCH Core Voltage if you are running stock speed. Can you link to your ram please, thanks

I ran Memtest86+ for more then 5, and I received no errors

Hmm, Well let it run overnight or all day while you are gone if you have the time to do so just to be sure.

Please let me have your full exact BIOS settings and I will see if I see anything that may be off. If you are using all Auto's Please also post me a screenshot of this app so I can see what several of those Auto's are actually giving you in windows >>
