So I slightly reduced my GFX OC and left my computer on with the monitor off for a few hours. When I returned home my computer was still on, but there was no video. My monitor just continued to cycle through the different inputs.

At this point I was convinced it was a GPU related problem. Anyways, I slightly (5mhz) reduced my video OC and took your advice and ran prime95 (still dont like getting above 73c wink.gif). About 10mins into it, I received my first BSOD. I then restarted and took 5 more mhz off the core and 10mhz off the memory clock. I proceeded to run prime95 again overnight. When I woke up this morning and it was still running (thankfully).

I think you may be right in the regard that I need to do a clean install of my video drivers after installing SP1 + the 40-50 other windows updates I installed a few days ago. I am going to get a 680 4gb in a few days so I will probably just wait for that.

Kind of a side question: In prime95 blend test I noticed it starts out using the full core clock and then downclocks to about 3.7-4GHz. Is this normal?

No it should stay constant. Have you looked at eventviewer logs atall to see if theres any indication as to the problem there?

Type eventvwr into the run command and have a look for any errors under Windows Logs > System

If you see any display errors its your graphics card, if its WHEA-LOGGER errors your CPU is at fault.

Do you have an SSD atall? If so which make is it?

When you are in your bios the cpu is usually under some load. I know my temps are usually 10 deg hotter in bios then windows. The dropping of the clocks, see if you can change long duration power (w) and short duration power (w) in your bios. Up those 2 settings and it should be fine. Also check and make sure you don't have windows set up in power saving mode. Set it to balanced or high power. That might also be the problem

Thanks for your reply. I will check those logs when I get home tonight (at work now).

As far as the clock speed dropping, what could be causing this? I do have speedstep/c1e enabled along with all the C states in the bios. Plus windows is on balanced; should it be on performance mode? I wouldnt think that being on balanced would make a difference.

Thanks for your reply. I will try upping those settings to see if it makes a difference. Would being on balanced mode really down my clocks in prime95? At 100% CPU usage I would think my core speed would also be maxed.

Also in games it stays at a consistent 4.5ghz and doesn't drop. Maybe in prime my computer thinks it's overheating and throttles back. Or maybe real temp is wrong and it really is overheating. Any ideas?

Prime95 clock speed drops when a core fails. Check none of the works have 'Stopped' with or without errors

None of them stop and no errors. I have stopped the freezing my lowering my clock to 4.4ghz, and I lowered my top prime95 temps to 69c by lowering volts. Still the clock drops between 3.8-4.2ghz.
