BSOD a couple minutes after startup

[Evan123abc]

Ive been getting BSOD's a couple of minutes after startup almost consistently every day. It usually happens twice, then my computer is fine and stable for the rest of the day.
This is a new build that Ive assembled mid october of this year, running Windows 7 enterprise.

Antec 902 case
Corsair TX650 PSU
G.Skill Ripjaws DDR3 1600 2x2gig
ASrock 870 Extreme 3 Mobo
AMD Phenom II 965 BE 3.4ghz
Sapphire Radeon 5770
Samsung Spinpoint f3 1tb HDD

This has been happening off and on since I built it. I ran prime95 a couple of weeks ago for 2 hours without issues. Also I ran Memtest86+ on a bootable disc for around 4 hours without any errors appearing on my ram.

This is my first post on Tom's Hardware and so Im not sure how to attach files or what to do about putting in the dump file info. This is a summary of what comes up on whocrashed

On Wed 11/17/2010 8:27:55 PM your computer crashed
This was likely caused by the following module: ntoskrnl.exe
Bugcheck code: 0x50 (0xFFFFF96000077D50, 0x8, 0xFFFFF96000077D50, 0x0)
Error: PAGE_FAULT_IN_NONPAGED_AREA

Im going to run Memtest again while at work today and will post results of that, any help would be appreciated
Thanks

Is this a legit version of windows? That file "ntoskrnl.exe" is part of the windows boot kernel.

Yes it is a legitimate and licensed copy of windows 7 enterprise. Could it be the operating system causing errors?

I was looking back at my crashes previously in whocrashed, its almost always 1 or more often 2 crashes in the morning then everythings fine, never get another bsod from gaming or anything.

1. Remove AC from PSU, take off your RAM , clean slot RAM, change another Clot RAM use 1 Stick.
2. CLEAR CMOS
3. Load Bios Optimal save ,
4. Test again your 1 stick RAM with Software Memtest86+ if any error replace other Stick and 1 stick have clear use It !...
5. if both have error replace New RAM (Clean from error)
6. I hope u have Stick RAM clear & u must install again Win7 fresh + Driver & Software, it's bad & Long! RAM have error can cause corrupt system file!
