I have to disable i5 cores to get my CPU to boot ANYTHING...

[AFurryReptile]

Windows 7, Knoppix, Memtest, Ultimate Boot CD.... it doesn't matter what I try to run, I can't do it unless I disable all but one core on my processor in the bios. It will boot then, but it is SLOW. Leaving cores enabled will either blue screen or simply reboot in a loop.

I've tried on two different motherboards... I can't even post with one of them.

I've tried with two different styles of memory, and all sorts of configurations... no fix.

This all happened after my power supply failed. It has since been RMA'd, and IS working. It killed the motherboard when it went, and that has since been replaced. I know it doesn't happen often, but is my CPU dead? I'm kindof at a loss as to what else to try.

Thanks for any help.

Edit: Heat isn't an issue. The bios shows under 40 C idle.

It's dead.

It's dead.

Yup. But another confirmation, never use a cheap PSU. You can never spend too much on a GOOD PSU.

Thanks for the confirmation guys... I'm hoping this is the last thing I'll have to buy to get this dang thing running again.

Mark - That's the thing that sucks, I was using an OCZ GameXStream 700 watt... there's no way it should have just blown up like it did. It's got over-voltage protection too, which I thought was supposed to prevent these types of ordeals.

man that really sucks. Do they have a warranty for blowing other components?

Unfortunately not, though my motherboard was replaced no-questions-asked by Asus.

It wasn't one of the refurb units from svc.com was it? I ordered two 850W OCZ PSUs from them, haven't used them yet.

Nope, my model was two years old. Apparently, OCZ warranties them for three, which I really can't complain about. The whole RMA process with them was pretty painless as well.
