Everything is ok, that is if you see things on the screen. If you don't see anything, check your monitor and video card first. Is everything connected? If they seem fine, your motherboard has some bad chips on it. First reset the SIMM's and reboot. If it does the same thing, one of the memory chips on the motherboard are bad, and you most likely
BEEP CODES1 beep : DRAM refreshing fails. Try to reset the memory first. If the error still occurs, replace the memory with known good chips. 2 beeps : Parity error in first 64K RAM. Try to reset the http://www.beepingcomputer.net/p/beep-codes.html memory first. If the error still occurs, replace the memory with known good chips. 3 beeps : Base 64K RAM failure. Try to reset the memory first. If the error still occurs, replace the memory with known good chips. 4 beeps : System timer fails. 5 beeps : Process fails. 6 beeps : Keyboard controller 8042 - Gate A20 is error. Try to reset the keyboard controller chip. If the error still occurs, replace the keyboard chip. If the error persists, check beep codes parts of the system relating to the keyboard, e.g. try another keyboard, check to see if the system has a keyboard fuse. 7 beeps : Processor virtual mode exception interrupt error. 8 beeps : Display memory read/write failure (non-fatal). Replace the video card or the memory on the video card. 9 beeps : ROM BIOS checksum (32KB at F800:0) failed. It is not likely that this error can be corrected by reseating the chips. Consult the motherboard supplier or an AMI product distributor post error review for replacement parts. 10 beeps : CMOS shutdown register read/write error. 11 beeps : cache memory error.
