I have a dell(pc1), pc with xp, What started happening is the light on the monitor led is blinking green when I turn it on and nothing comes up with no beeps. I swapped HD, power supply, video card, ram, nothing changed. I took processor out of pc1 and swapped it with working pc2, nothing changed but now the good pc2 computer wont boot and the monitor is blinking on both when I turn it on. After about 10 minutes pc2 is booting up.
I am wondering if their is a problem with the processor and something got hot causing pc2 not to boot until it cooled down. Does it sound like the MB and processor are bad since when I put the good processor in pc 1 nothing changed and still didnt boot and then when I took processor out of pc 1 and put it in working pc2, pc 2 wouldnt boot and monitor just blinked. THen I put the good processor back in pc2 and it wouldnt boot for about 10 minutes? What do you think?confused?

I suspect that the motherboard is the root problem. One suspect circuit is the voltage regulator section. If the voltage regulator provides too high a voltage to the CPU, it can wound or destroy the CPU.

Keep in mind that unless you install an identical or very similar motherboard when you replace it, Windows may not boot up.

Also, if you install a non-Dell motherboard, you may have activation problems with Windows XP or Vista.
