My PC won't boot; fan does come on; it beeps continously(each beep is long) it does not even get into the BIOS; I bought some new memory; pulled out the floppy; CDROM; only hard drive is in master slave; and still nothing. It does not even attempt to display anything on my monitor. Could I have a bad display adapter. It is an on-board display adapter. My mother board is 651M-L/650GM-L series based on SiS 651/650GX (702 pin BGA) & SiS 962L MuTIOL Media I/O (371 BGA).
