Which version of the P6T board do you have? I had a P6T Deluxe v1 and had to upgrade to v2 in order to stop my BSOD's when I hibernated.

The first thing to do is to reset the system to factory defaults (no overclock). This will tell us if it's due to the overclock or not. The memory dumps show default as 2.67 gHz and current as 3.1 gHz.

Beyond that there's no specific cause to suspect here. The BSOD's blame memory corruption - which can be due to the overclock or to faulty drivers. Let us know if resetting the system to default fixes things. If not, then start with these free diagnostics:

I suggest starting all troubleshooting with the following diagnostic tests. They'll save you a lot of time and heartache if there is a hardware failure, and you'll have the disks on hand in case you need them in the future:

Basic P6T

I bought my computer from CyberPower with it already overclocked. The motherboard box does not say deluxe on it, so I assume it is just a basic P6T. I haven't messed with BIOS much or overclocking, will the P6T manual show me how to adjust the overclock back to factory? And then do I just have to wait a week and see if the BSOD comes back?

I will try those diagnostics in the meantime. Malewarebytes and TDSSKiller are coming up with no problems on my machine.

Do BSODs harm the system or are they just annoying? If I had to reset the overclock to fix the problem, and there wasn't anything else to do about it, that would be frustrating to have to leave it at the factory setting.

What is the best way to test the drivers to see if one of them is faulty? Or is that in one of the diagnostics in your post?

Thanks for the help.

You'll have to either contact Cyberpower or make notes about the settings on your system if you want to regain the overclock in the future. In most cases (with Asus boards) you can reset the BIOS to default/fail safe values and that will stop the overclock. Until then we'll try and work around the overclock (because it'd be a shame to remove the overclock and not be able to get it back correctly) - I haven't done any overclocking in almost 10 years!

BSOD troubleshooting is й scientific and й guesswork. So we fix things and then we wait to see if the BSOD comes back. In most cases going a week without a BSOD means we've probably fixed it. Going 2 weeks means that we've most likely fixed it. There's just no guarantee's here :0)

The BSOD itself doesn't harm the system. But if there's a hardware cause for it, then that may harm the system.

There are several ways to test drivers. We, at times, use Driver Verifier (with certain specific settings). Or we remove the drivers to see if the BSOD goes away (most BSOD's are caused by problems with 3rd party drivers).

So, while waiting for the overclock to be reset, let's proceed with the diagnostics. If they come back OK, then we'll try some free stress tests (but I'd prefer to do them without the overclock working). If we have to, we can do them with it - but that'll be testing both the overclock and the hardware.
