Since you are unable to get into the bios ALA black screen and blue line at the bottom, the only recourse would be to swap the bios chip itself with a known good one if you can to eliminate the possibility of some other motherboard component starting to fail.

have you tried clearing cmos?

have you tried to manually configure your cpu? refer to your manual.

maybe one of these steps will let you access bios

some suggestions

A cut and Paste from I boot the BIOS all it says is "BIOS checksum error, press F1 to continue...". What should I do?

You should also try clearing the CMOS by removing the machine's power cable (important!) and then using the CCMOS1 jumper to clear the CMOS memory - then reboot and immediately enter SoftMenuIII to set the correct CPU speed and then the other BIOS settings you require. If this does not help, then you probably have a corrupted BIOS and will need to replace or reprogram it.

Note that companies such as BadFlash exist, who will reprogram your BIOS chip for a modest fee. A BIOS flashing service is offered in Germany by, in Italy by and in France by Alternatively contact Abit directly who again will sell you a new BIOS chip for a similar cost. To prevent these problems in the future you may wish to consider using a BIOS Savior.

Good point Vera, about the clear CMOS, especially after a Bios flash.

thanks to all for the reply,
i just thought of something else

took of the cooler from the cpu, all the corners from the core are chipping off. i think this is the problem.
but the cpu still works, is that possible

It is possible as long as the core and interconnects to pins are not damaged, I had a Duron chip with what appeared to be a small hole or pit on the corner that functioned just fine.
