My friend has a pentium 4 1500 mghz computer that he's been having problems with. His computer is custom built by another friend of his, and he's had it for about 6 months now. I'm not sure of the exact specs (im gonna check it out tomorrow), but he's got an asus board in there. The computer was working fine until he got back from christmas break, then when he tried to boot up it just wouldn't work. For some reason it gives him something to the effect of "system startup failure" over and over again, and a red light indicator on the front blinks. I haven't looked at it yet, and really don't know exactly what he's talking about, but I'm going over there tomorrow to check it out. Any suggestions on what could be the problem?
