urgent, computer can't start, monitor is black but fans are running

[shenlingstyle]

Need some urgent help! I overclocked my athlon xp 2800+ a bit and my computer isn't starting anymore. The exact things I did was increase clock speed to 180 MHz and cpu voltage to 1.7V. After a restart I don't hear the beep nor does my monitor respond. The cpu fan and power fan are both running. I tried taking off the cmos battery for a bit and reinserting it but same problem occurs. Is there any way to reset this? Thanks for any help, really appreciate it!!

Try reseating the RAM and cards. I know that this may not be the problem, but if you have burnt something out on the MB, it will be a lot worse.

Try this first.

I think bartons run at 1.65V. 1.7V shouldn't have killed it. Popping out the cmos battery should reset it as long as it's out long enough. Don't you have a cmos reset jumper?
