I had just purchased this PC lightly used and it had a Core 2 Extreme quad in there. I had switched it with a core 2 duo, same socket type LGA 775. Quad core works in the computer I put it in. That was a Dell inspiron 560. When I put the Core 2 Duo in the workstation. The computer will not boot. No error beeps. Nothing. However, the processor works fine back in the 560. Any advice! I really don't want to trash it!
