So the other day my computer wouldn't start. I hit power and just.... nothing. It powers on however theres no post or beeps or anything. I had some psu issues earlier in the year so i thought aha it must have just given out. So I got a new one, installed it.... nothing

Next I went through the whole troubleshooting shebang, I took everything out and tried to boot, no beeps, no nothing. So I tried different combinations of different ram, different video cards, taking out battery, putting battery in, still no post, no nothing.

Figured damn it must be the motherboard, just finished installing it, still no post. Tried different video cards different ram and just nothing I am getting at my wits end. I think well the only thing I haven't tried is a new processor.

So just to test I take my processor and put it in another computer in the house which is compatible with my processor. I put it in and power up the computer SAME problem, no post no nothing on completely different computer. Figure I have it figured out, however when I put the old processor back in the test computer, it still isn't posting. Is it possible that my processor is damaged in some way that it is frying whatever socket its put into?

My old mobo is a GIGABYTE GA-MA790FXT-UD5P, the new one is a gigabyte 970a-ud3
ram is mushkin 4gb x2 sticks, ddr3
radeon 6950 2gb
AMD Phenom II X4 945 Deneb 3.0

Really have no idea where to go from here aside from getting a new processor however theres the issue that this processor may have busted another comp? Any enlightenment would be greatly appreciated.

Also I went through a guide on these forums that is a no-post "checklist" though I suppose Ill find comb through it again

I suppose it is possible that the CPU could have busted the other motherboard.

Stranger things have happened.

That being said, before you give up on the 2nd PC, I think you should put whatever CPU it used to have in there and take the battery out for 30 minutes and put it back in. That might get it going again.

Let me know if that helps the 2nd PC, and then I will be able to better advise about the main broken one.

I can't think of anything else that would really explain this behavior. I hate suggesting people to spend money, but you may really want to go ahead and buy a motherboard and try it in the old PC with the old processor.

Ah that wasn't entirely clear in my initial post but I did buy a new motherboard which I tried, and that didn't work either. Same issue, and after that didn't work, I tried my processor in a completely different computer and after the "test" that computer also wouldnt post/boot

Have you tried posting in mobo forum? If not, try it: they have some really great trouble shooters there. Nikorr and Jaquith are great.

That is what I meant, you may need another motherboard to repair the 2nd computer that quit working.
