PC won't boot

[WylieC0y0te]

Hi all

Hoping someone can help me as I am at a loss.

My pc all of a sudden will not boot or post. All fans spin up etc but there is just a blank screen, no bios, no beeps, nothing.

Things I have tried.

3 different power supplies that I know work, even with other pc's

Different graphics cards, the card that's in the pc that doesn't work, works fine in another, so it's not that.

Re-seated the CPU

Cleared the CMOS, by both removing the battery and using the jumper.

Different RAM sticks.

I have even bread boarded and plugged things in one at a time.

Nothing works.

The only thing I can tell you is, is that I will get long beeps when there is no RAM plugged in, which I know is normal.

Any help would be greatly appreciated.

Thank you.

Sounds like your motherboard or CPU are toast if you have tried different RAM.
Only way you can test is if you can get another CPU that you know works or try your CPU in another PC.
What are your components ?

Thank you for the quick reply.

Motherboard is TF570 SLI A2+ Biostar

AMD phenom II black edition I think.

Corsair 450w PSU

8GB ddr2 RAM

Have an ATI card in there as well, not sure of top of my head exact model as doesn't say on it.

Also on this specific board the led light that comes on, as far as the mobo manual is concerned, that means bad ram, but like I say have tried others.
