*Sorry mods didnt know exactly which forum this belonged in so posted in technical support, cpu, and motherboard forums*
My friend purchased a new motherboard (msi k7t266 pro-r) and amd xp 1600+ cpu we plug everything in, doesnt post and it hangs on according to the manual using the D-led, the graphical diagnostic led, "testing VGA BIOS-This will start writing VGA sign-on message to the screen." I restart and then we get all red leds which says "system will hang here if the processor is damaged or not install properly." Power down check cpu connections and core to look for cracks/bent pins/smell nothing, check power connections and make sure cards and DDR ram*motherboard does support it, samsung pc2100* is seated properly, strip to bare components:mb,ram,video,cpu/hsf still nothing. We decide to test her cpu and motherboard with parts from my working (at the time)computer (ECS K7SEM and 1600+xp) So I take my cpu out and put her new 1600+ in with HSF of course powers on nothing concluded her chip is bad. K Then we take my chip and put it in her motherboard same thing happens that happened in the very first place hangs at VGA bios testing and the restart and then all red and nothing, fans power but no post, no bios. I conclude that her motherboard is bad. K my concern is that when I returned my cpu into my computer it doesnt post or beep now. I tried my friends Amd athlon 1 ghz and nothing. I'm at a loss cant be ram, or power source cause all I moved was CPU. Heatsinkfan is plugged in so rpm monitor is not it. Not grounding issue never moved motherboard. I suspect that her motherboard is defective destroyed her processor as well as mine and putting those destroyed processors in my board killed my motherboard? Any thoughts on this and I'm getting a refurb motherboard I'm afraid to put my possibly broken cpu(no smell,bent pins, crack core)in it causing it to break my new motherboard aswell

Follow up: I forgot to mention I tried clearing bios by shorting jumpers and returning them, and by taking out the battery for a few minutes. Please help

Also when manual says "CPU support:Socket A for AMD Duron,Athlon Processors" XP follows in the Athlon portion or is it usually listed seperatly? Thanks

Yes, these are computer parts...not the plague. Its not likely moving a CPU from your motherboard to hers and back will damage your board if you didn't physically damage the CPU(shorted pins, etc) in the process of swapping it.
Now about her problems, are you sure the CPU fan is connected to the right header(and has a functioning RPM sensor)? Reseat the videocard, RAM and recheck all connections(FDD and HDD cables for proper orientation-red wire to pin1 and twist in floppy cable on drive side) and after that clear CMOS again. Goodluck.
