Installed sp3 on a clean, brand-new hard drive after initial XP home installation,137+GB. I already had SP2 on my computer and SP3 was automatically downloaded as a update. Asked to reboot system. When I clicked on the reboot-now link, I recieved the blue screen of death. Only flashed for a second so I was unable to see the error code. After restarting computer and @ initial rebooting of my console, I recieved the following error at the time of system startup: BIOS ROM checksum error Detecting floppy drive A media... INSERT SYSTEM DISC AND PRESS ENTER The BIOS copyright notice is loaded before this error. I cant enter the SETUP menu at all to change the boot drive back to my HDD or CD rom. I had previously removed my floppy drive years ago, but after I first recieved error message I went ahead and reinstalled it. Since I only have recovery boots and XP software on CDs I dont have any flops for system recovery. I am not sure what to do next. Any suggestions would be Appreciated. AMD Socket A Duron, M811.
