Ok, I gave it some more thought. since you had caps go bad on the board that pretty
much leaves anything else thats plugged into the computer that could be bad. Now,
if your sure it isnt the power supply, or the wall supply, I see it could be one
of two things. if the caps were near where the power supply plugs into the board
then you may have damaged a perifrial card such as graphics or modem with voltage,
if the caps were near the chip or ram, you may have damaged one or both with frequency.
And yes if it isnt a power supply issue, it definatly sounds like a timing problem.
Your ram could very well be bad. At high speeds system clocks are critical. I dunno,
im tired I've been up for 40 hours. I wish you luck.
