This is bizarre. When I try to boot up after my computer has been off for a day or two, I get a long beep followed by three short beeps and nothing shows up on the monitor at all. Re-booting/powering down and restarting are all ineffective until about a half-hour after I have left the power on (w/ nothing on the screen). It seems it needs to warm-up or something. Very odd. I can tell that it is not booting the OS by listening to the HD, and the fact that the keyboard does nothing(CTRL-Alt-Del does nothing). Only after about a half hour, what does seem to help is unplugging the case and then plugging it back in and booting up. (Approximately a half hour)
I have tried switching memory and video cards to no effect.
My system specs:
Retail Celeron 300A (not overclocked)
128MB Micron RAM
INWIN A500 case
Maxtor 8.4 HD
Any help would be much appreciated as it is VERY annoying.
