I am running a computer with XP home, an Asus P4S533-X, with a 2.6 celeron chip and 1.5 Gig of RAM. It was working great, then just locked up, it smeeled like something was burning. I shut it down and now when I reboot it the fans come on, the board's green light comes on but nothing for about 10 seconds and then I just get one long beep (approx 5 secs). I reseated the RAm, but no resolve. Any ideas?
