I have an old MSI K7N2 Delta 2 motherboard with a Athlon 3200+ CPU. Recently, the computer started acting flakey and it finally crashed and would not POST. I suspected a bad PSU. The following troubleshooting has been done. 1. replaced PSU with a new, working one. PC posts, passes memory test but does not proceed further. cannot enter BIOS when holding DEL key. 2. disconnected hard drives. jumpered CMOS battery. PC Posts, splash screen defaults, cannot enter BIOS when holding DEL key. 3. removed CMOS battery. PC Posts, splash screen defaults, cannot enter BIOS when holding DEL key. I don't know what else to do. I am concerned the mobo might be fried. I really don 't want to throw a whole lot of money in this 6 year old computer as it is so ancient. The only thing left is to remove the wifi card and fax card. update: took out all extra cards. also tested ram cards one by one (all 3) still the same. I even changed keyboards. I think the mobo is toast, but I do welcome suggestions.
