ohitsmonday,
That is the old AMD 761 chipset. I would try opening the case and checking that the AGP, all PCI Cards, and RAM are fully seated.
If you see a lot of dust inside the case, it would be worth blowing out the inside of the case with compressed air.
If the comp still will not boot, I would try removing the Power Cord from the Power Supply and the Battery from the Mobo. Wait a good 15 to 20 minutes before putting them back in.
Take Care,
Richard
