What would cause a functioning computer to suddenly give a "disk boot error"? No new software or hardware has been added anytime recently. Computer was working fine. Sometimes the computer will boot up just fine and other times we get the "disk boot error" message. Cant seem to narrow this one down as the error does not occur 100% of the time. Also the boot up time is VERY slow. It does POST every time. Gets just past the post screen and gives error message before it can load windows. IF windows loads, everything seems to run smoothly.
My husband has a custom built computer that we have been running for about 6 months. Yesterday morning he tries to launch a game and the computer reset itself. When booting back up he gets a "disk boot error" message. Opened the case, cleaned it out, checked connections and cables, checkd the cmos battery, and then tried booting from the windows CD. Finally did a format and reinstall of windows on the C: partition. Still getting intermittent "disk boot error"
Disconnected every non essential piece to try and isolate the problem. Any ides of what we should be looking at? Very frustrating.
