Basically,

I wanted to underclock my computer so I could play WarCraft II again without an instantaneous scroll (which is a pain) so i underclocked the multiplier, got out of the BIOS and then realized that i never unlocked the multiplier on the chip in the first place!

I reset the jumper for the BIOS but well... the power comes on, the fans turn on, but there is no action, the screen never lights up let alone the BIOS coming on screen.

I put in an old 700 MHz. thunderbird just to see what would happen and it beeped, but that's the only time it's beeped in a while. otherwise no sound... just fans and LEDs.

I have a K7T266 PRO2 with an Athlon XP 1600..... anybody have any ideas? :-/
 
take out the cmos battery while the power is unplugged, leave it out for a min or so then put it back in and see if you can boot, make sure all connections are tight, and everything is in the right spot, see where taht gets us.
 
Yeah, just look in your manual for how to "reset the cmos." Follow those instructions, and it should work. You'll have to reconfigure your bios settings, but at least it should boot.

As the other people have said, just reset the BIOS. It may be a jumper or a switch on your mobo. Check your manual. Once you find it, move the jumper/switch to the other position, power on the PC, wait about 5 seconds, then shut it down. (5 seconds is more than enough time to make sure the system has cleared it's settings) Fix the switch/jumper back to it's original position. This should allow the system to POST again. If it does not, instead of removing the CMOS battery. They can be a pain to remove, and if you aren't careful, you can actually destroy the battery's housing so that the battery will not stay seated properly. This is really a pain because you have to figure out a way to rig the battery socket to hold the battery in place again. A better option (learned in an IBM class) is to slide a business card underneath the battery instead. You still prevent contact to the connector, but you do not have to remove the battery from the system completely, thereby eliminating the chance that you will mangle the battery's housing.
 
you guys didn't read the post, he already reset bios through onboard jumpers, that didn't work, so removing the battery and unplugging the system is in my opinion the next step, atx motherboards I believe always receive power when plugged in (i think that is right) so that is why I suggested unplug the system when doing this to prevent bios from being saved.
