The system does not boot. No hd activity, no keybrd led flash on/off, monitor goes to sleep. All caps on mbrd and video look good. Will try to isolate?
Any suggestions? It is an older system now but stable for long time.
It could be your motherboard,RAM or PSU.
Remove all of the dims expect one and retest.If it didn't help,try to test your PSU/Motherboard in another system.(Or put another PSU/Motherboard in your system and test with it)
Try a spare power supply first; I always have one for problems like this. Otherwise, I would look for a p35 or p45 Intel board (which ever is cheaper) for a replacement.
