Hi. So this morning I came down to my pc off. It now just freezes on the windows icon loading screen. I tried to do a fresh install and got a bsod code 9c. Could the cpu be fried? I then tried to reinstall using raid 0 on 2 ssds, win install files loaded to the win lead screen then froze again

09C usually happens due to not enough voltage - sometimes need to increase VTT or system agent 1 notch occasionally it needs a slight bump in vcore or reducing the overclock a little.

If its a system that has been overclocked and stable for awhile - I see a 2600K in your sig then it might be the CPU is degrading and no longer stable at the original overclock and settings.

I reset to default in case it was an overclock problem. Same thing. It just hangs on win load screen. I wax thinking the cpu may have died??

Try running memtest86 - possible one of the RAM sticks has died.

Memtest running now. I as I said I have taken off the overclock for now. I think I have a parted magic disc somewhere. If it boots up with that then can I assume the cpu is working ok?

If memtest is running then the CPU isn't (completely) dead. Working OK though is another matter.

Memtest was ok. I tried running a cronies to recover.again it locked up as soon as acorns started. I have ab acronyms boot disc so I tried that and it still froze. I'm thinking the cpu is bad

Try running the Intel processor Diagnostic Tool...

Does the pc need to be booted into windows to use that ?

Just tried another drive I had with win 7 installed. same thing win loading screen and it freezes so it's not the ram or hard drive

Possible that the CPU just needs a bit more voltage now (even at stock clocks) because of years of running with a hefty overclock.

I'd be tempted to give it a couple of clicks more voltage and see if that helps.

As I said I have reset the defaults so it's running at stock. Still freezes

unplugged evrything and took out 3 rams sticks. put in a different gpu, still froze then bsod 9c. it has to be the cpu???? anyway i just bought another 2600k from the mm. if not i can resell it. thoughts???

aahhh ok i didnt see that bit.lol

It was just an idea, could be slight chip degradation.

In either case, hopefully either that or the new 2600 will sort it.

More volts made no difference

OK thats a shame...

got the new 2600k today and it works again,so it was a dead or nearly dead cpu. i took the waterblock apart and it was quiet blocked so i'm assuming it got too hot while mining
