I had a problem with one my computers. One of my friend checked and suggested that it might be a problem with processor.

The one i had was a dual core 3.0 ghz processor(not sure about the model number).
I have a mercury PI945GCM motherboard.

I bought a new processor intel E5700, 3Ghz, LGA775, 65W, 800FSB(Dual core).

When I used the E5700 and booted it only stops on the first Mercury screen. No error message.

I did a research and found that my motherboard was 1066FSB.

Is 800FSB processor compatible with 1066FSB motherboard? Is that why the computer is not booting?:mad:

If yes then can i sell this online? Coz I dont think the shopkeeper will take it back. Is this E5700 is a good processor and has good market?

I did a bit of research and managed to find the motherboard manual on line and the motherboard (assuming you have the correct model no.) does support CPU's with 533/800/1066FSB - so in theory the chip should work. However there are reason why some motherbards wont accept CPU's despite having a matching FSB and socket design.

and a litle more digging came up with the official CPU support list for your motherboard :-

it appears that your CPU is not supported - thats the bad news over with.

CPU's are very well built and rarewly go wrong - what made you think it was a defective CPU in the first place ?
