Hi, I have upgraded my dual CPU Tyan Motherboard from 2 Athlon Dual Core CPU's to 2 Athlon Quad Core CPU's and I cannot get the Computer to boot! even to the Cmos Screen.
I get no beeps, the CPU Fans speed up, but it just sits there.
THe Quad Core CPU's are 2nd hand but are supposedly tested OK. I have stripped all the PCI Cards out, reset the bios, changed the Ram placement, tried one CPU at a time but all to no avail.
As soon as I put the original CPU's back in, the computer boots and is on it's way.
Does anyone have any idea what may be causing the problem?? All I can think is that I have bought two Dud CPU's
Thanks for any help.
