So I got a BW 350 new back in 1999 and immediately OCed. I tried OCing it to 450 and it didn't work. I tried 400mHz and everything worked fine, its been that way ever since. The BW has served me very well and I have since maxed the RAM and put a Radeon 7000 GPU into it and was using it as a TV media computer. It was working ok/good and so I thought I'd try to OC it again to 450 to see if I could get it working and squeeze a bit more juice out of it. God what a stupid idea. It wouldn't work at 450 so I set it back to 400, it wouldn't work!!! Even back at 350 it won't work. God I can't believe I did this. I don't have the original block of jumpers that came with the computer (I know what box its in, but just can't find it). Would replacing all the jumpers give it a chance at life again?
