I agree with CrossFire851, i dont think that will help you. But here is the info:
To reset your bios you should have a look at the manual that came with your machine as it does vary. here's the standard sequence:
Usually you remove the power cord from the wall, take out the round cmos battery and find the 3 pins nearest the battery and move the jumper from pins 1 and 2 to pins 2 and 3, wait a minute or two and then put everything back the way it was, move the jumper back to pins 1 and 2, put battery back in, power cord back in wall and turn on pc. Make sure you ground yourself before you do anything. Keep on hand on your metal case will do the grounding job for you. I use an electrostatic grounding wrist-strap device that you can buy at any computer store for $10.
If the manual for your machine is on cdrom then you can read it from another pc, or go to the mfgr website from another pc and get the bios re-set info there. It does vary.
Also, bad ram can cause your pc to keep rebooting. try removing one piece of ram and interchange them, see if your pc boots properly.
You can also try using f8 and boot to safe mode.
