Windows 7: BSOD NIGHTMARE

Ram + HDD is OK
And i have a strong feeling that my Graphics Card a ATI RADEON HD 5770 is failing as my screen is flickering and going fuzzy and occasionally goes off and comes back on.

Plus when my pc turns on it says that my AMD PHENOM 2 BLACK EDITION 6 CORE PROCCESSOR only has 5 cores activated when it alwys used to say all 6 where active why does it say that?

Have you tested your CPU yet?

If you haven't, run all three Prime95 tests for a couple hours each

I can only start my computer using "safe mode with command promt" and speed fan says the temp for one of my cpu cores are -174!
That's defenately not right and when I try to start the tests on Prime95 I press ok and my pc just crashes dumps the physical memory and restarts. I select small FFTs

It's starting to look like your CPU has begun to fail or is defective. You had stated that you have auto overclocking enabled. I would like for you to disable that and re-run Prime95. Are you able to boot into safe mode with networking? If you can, I would like to see a system report so I can see what's going on.

I had a little look in the bios config and I found that core 3 on my cpu had been deactivated so reactivated that core. But after that I couldent load up safe mode with command promt. So I deactivated core 3 and tried again and I was able to start safe mode with command promt but then I tried Prime95 again, selected small FFTs pressed OK and it just restarted.
But I'm going to take it down to my local computer shop and hopefully they'l be able to run a hardware diognostics and software diognostics on it.
I'l post the results as soon as i get them.

Hi sorry I havent replied for a while.
It turned out that my cpu AMD PHENOM 2 BLACK-EDITION X6 was faulty so I temporaraly replacing it eith an AMD SEMPRON X1 cpu. So im going to send my cpu back to AMD and hopefully they will send a replacement.
Ive noticed that my PC is faster than before and that proves that the old cpu was nackerd anyway thanks for all of your help.
