I've had this a few times within a twenty minute period. Unsure of what it could be. Doing some quick research I've found it might be hardware related (GPU, CPU, etc.). Here is the info after restart:

Problem signature:
Problem Event Name:BlueScreen
OS Version:6.1.7601.2.1.0.256.1
Locale ID:1033

Additional information about the problem:

Any assistance is greatly appreciated, thanks in advance.

Open BSOD.txt in Notepad, copy all of the content, and paste it into your next replyThanks for the quick reply. Here is what came up. I guess it was two different BSODS.

I've honestly never seen the first bsod before. The second one is related to your ati driver. Did you recently update the driver for your video card?I did update the driver last night to the latest one, I just don't remember if it was before or after that BSOD. Might have been after. Thanks for your replies, Allan.Revert back to the original driver...
Newer drivers are not always better drivers...As patio suggests, you should only update drivers if there is a specific need or reason to do so. Please roll back the driver to the previous version and let's see what happens.Alright, will do. Finishing up at work, and I'll post back.Alright, GPU driver rolled back, seems stable now I suppose. However, upon shutdown, I got this BSOD:

Also did a memory test with no faults.Do you have SoundMax audio drivers installed ? ?
If so do the same as above...I do not have SoundMax drivers, just Realtek HD Audio. Should I still do the same?That is a very rare error and is usually caused by a bad or conflicting driver. If you updated any other drivers recently, roll them back as well. Alternatively, you can use system restore to go back to a date before you updated the drivers.So on a whim, I decided to pull out one of my RAM sticks. No crashes/BSODs. I haven't gotten intense with usage yet, but I was able to play a couple games for about a half hour each without problems. I'll post back if anything happens. Thanks for the help, guys!
