Hi. I bought an Asus P5GCMX/1333 motherboard off of eBay a little over a week ago. The board worked great, except it did not fully support the E7400 processor I installed in it. It was running the oldest version of the BIOS. Version 0207, I think. This board does not support bios updates by USB. Only floppy or CD. Tried AUFDOS, that failed. CD drive I'm using is broken, so that was why it failed to find the file. Took several tries with a floppy, but the floppy was bad. Once I found a good floppy, it flashed the BIOS successfully, version 0413. Ever since that I'm getting this:
"00 USB Device Detected. CMOS Checksum Bad. USB over current status detected System will shutdown in 15 seconds!!"
Can't get into BIOS. The EZ-Flash utility still works because I downgraded the BIOS back to the original version, that didn't help. I ordered a new BIOS chip (with the 0413 version), that didn't help, either. I unplugged ever USB device, including the front panel connectors. I checked the USB port Ω with a mulitimeter, and it read 19.8Ω on all the back ports (power off, cord unplugged). I did the same with my laptop (which works no problem) and it read 534Ω. I was checking on pins 1&4. Oh, and I removed the board from the case and ran it out of the case, too. That didn't help, either. What is wrong with it? Help would be greatly appreciated.
