So my Dimension 4100 froze during a 3Dmark run and was totally dead except for fans spinning after that. My first instinct was caps since I've had five power supplies die on me in similar fashion this month alone so I recapped it and the motherboard. Still dead, still no diagnostic anything to work off of. The voltages tested fine at 5.08v and 11.8v so I doubt its the power supply now (I replaced every single capacitor in there) and if I have the hard drive connected I get a solid hard drive light but the power light isn't on nor are any of the four diagnostic lights in the back. I pulled the ram, gpu and cpu and tested them all in another S370 board I had and they worked fine there. I've tried oven reflowing the board for about nine minutes and letting it cool for a half hour until it was cool to the touch this evening but still nothing out of it. Is this board hosed or is there anything else I can try? I do see the green light on the board when it's powered on but that's all, the fans spin and nothing else.
