Hi!\n\nI have an A8N32-SLI Deluxe system (4800+ processor, 2 sticks of 1 GB PC 3200\nRAM, 256 MB NVIDIA PCI-E video, 2 500 GB SATA drives in a JBOD array, one\nATA storage drive, 500 Watt power supply) that has been rock solid for\naround a year. When I came in to work this AM, the machine had a text\nscreen that said something like "BIOS Checksum error, looking for floppy,\nlooking for CD". I inserted the ASUS CD to activate the automatic BIOS\nrepair. The machine seemed to do the repair, then left the message on the\nscreen (paraphrasing) to power down the machine to get your system back. I\ndid so, but I then got the original error message back. I repeated the\nprocess about a dozen times, then decided (after Google research) to reset\nthe CMOS by using the procedure in the manual (unplug the machine, pull the\nbattery, move the jumper position for ten seconds, reset jumper, reinstall\nbattery). At that point all that would happen when I powered up the machine\nis that the fans would all power up, the HDD and CD lights would come on,\nand the green light on the MB would come on. Nothing else happened (no\nbeeps, blank screen). I tried reseating all connections. I tried only using\none stick of memory (trying all combinations of slots and alternating which\nstick I used). I did not have by voltmeter at work so I couldn't check the\nbattery voltage or the output on the power supply. I am hoping someone here\nhas a suggestion as to what to try next. Also, FWIW, the BIOS on this\nmachine has never been flashed; I wasn't doing anything to the machine when\nthis happened, as this apparently occurred sometime during the night.\n\nTIA.
