So my school recently let me take home a Dell Optiplex 320, and I had purchased a q6600 for it. it originally had a Pentium 4 in it. (Pentium 641). But now, when i turn it on, (with a new 500w psu), it has an amber light, and the fan goes to full speed. It does not boot. I tried switching out the processor with the original, it boots. i switch the ram around, nothing. tried the original psu, nothing. I hope this isn't bad. can you guys help me out?
