I assembled a desktop maybe 8+ years ago, the board finally went South. It's an ASUS P4C800E motherboard , uses a Pentium IV socket 478 CPU, dual channel DDR400 PC3200 RAM - has 4 slots, I've got 4 modules for total 3 gb RM. I'm not a gamer, just fool around with home video & pictures, some online sports, watch an old tv show, surf the net, simple things like that. It's always been plenty fast for everything I do. When it happened, all the lights flashed rapidly and it beeped rapidly when I tried to start it. Now the switch has no effect - the board powers up as soon as power is supplied to the machine. Can't force quit the machine either. Nothing on the monitor at all. A tech shop checked it and said the board is bad. Sounded like they checked it by swapping cpu's, RAM, etc. I had tried a new battery first, had hoped they would test the chipset, etc. but doesn't sound like they did much if any of those kinds of diagnostics. I do have an ASUS setup disc I got with the board when I bought it that ASUS says I can use to reinstall the BIOS, haven't tried that yet. While I was poking around inside making sure there were no loose cables or other obvious simple problems, I cleaned it. The CPU heat sink came off the CPU so I have to get some of the heat sink grease and reattach it before I try to start it again. Assuming I do need a new board, I've found that boards that will accept that old Pent IV and my ram are scarce. So far just some real cheapies on Amazon and eBay. Would like to find i.e. a refurbished direct replacement, or at least something basically comparable. Or even a reputable shop that may be able to repair the board if I send it to them. Would much appreciate any leads or advice. The machine serves my needs and I'd like to avoid the cost of a new CPU and RAM. Thanks!
