|"i tried reseting the bios by shorting the jumper and now it won't start up"|
Did you do the reset properly?
1. unplug the power cord
2. move the clear CMOS jumper from the normal position to the clear position, wait a few seconds, then move it back to the normal position again
3. plug in the power cord, power up the system, then immediately enter the BIOS & fix the settings
NOTE: if you leave the jumper in the clear position & power up the system, you can damage the board
