Windows 7: Dell Optiplex 755 Cpu Problem

Dell Optiplex 755 Cpu Problem

Hello, I was told in one of the forums that a Intel CORE 2 QUAD PROCESSOR Q9650 SLB8W 3.0GHz 12M CACHE 1333 MHz FSB would work in my Desktop. I purchased it on E-bay and installed it with the already upgraded bios A22. It did not work. I tried to install my original cpu that did work and now I cannot get it to even post. I have removed the battery for an hour and that did not help. I tried a different video card in case that was the problem. I get absolutely nothing on the monitor. I am at a loss. Does anybody know a trick or two to get it back up and running. Thank you very much for your time. Robb

Best option is to post on the Dell forums, where those familiar with Dell's can help you. Dell Desktop Forum http://en.community.dell.com/support-forums/desktop/

The Dell specs list these 3 CPU types: The Q series, based on what the specs show would not be supported.

Intel Core™2

The Q9650 3.0 is possible to use. Must have Bios A20 and only A20. Not 22. Dell Bios locks processor family's. The A20 opened up the box for e8400. and in so any 1333fsb 45nm Q35 chip set compliant chip.
