I think my mobo is dying, but I want to run this by the rest of you before making that determination. Symptoms: Last night we had a guest staying overnight, and my PC with all its fans can be a bit loud to those not accostomed to it, so I shut it down. Today when I turned it on it started acting very strange. The bios failed to id both my harddrives, or my RAM, and then gave me the BSOD with "IRQ is not equal or less than....." screen. So I restarted the computer. This time it ID'ed the primary HDD but not the slave, ID'ed the RAM but not my video card. So I moved my monitor connector to the onboard video port to get the monitor to work. But the comp hanged on the Windows loading screen (with the blue night ridder bar). So I restarted again, this time the computer Id'ed everything correctly except my video card, and booted normally (after getting the safemode boot option screen). It also flashed that new hardware was installed and after reviewing the hardware manager it installed the S3 Graphics ProSavageDDR (microsoft corporation), under display adapters. I have no idea what happened to my Geforce 4 TI 4200 device drivers. They have just disappeared. Now my first thought was that maybe the bios battery was dying and that the bios was losing all the settings, but upon reviwing the bios setting nothing seems to have changed (best I can tell) and I have no loss in the system clock. Both time and date are correct, unless it updated with the internet before I could even check it. So I am not really 100% positive what is happening ro what the cause is other than the mobo crapping out somehow. Any ideas, troubleshooting thoughts, etc are welcome. Anyone have a "A" socket mobo there not using?
