I have a dell optiplex gx 260 – new hd 500gb, 2gb memory. 2 cd/dvd writers. This was working fine. I reloaded the os and then restored the data 2 months ago. 9 days ago turned on the computer, saw the dell splash screen with options of F2/12 then splash screen went off like normal and all I had was a blinking prompt in the upper left hand corner of the screen. Booted to diagnostics – all passed. Swapped power supplies. same result wouldn’t boot from hd. Reformatted hd, reloaded windows and minimum software – office, anti-virus, adobe stuff, firefox. Added users. Worked great.
Next day wouldn’t boot again. Followed same process of reformatting hd and loading os and sw. This time made ghost image. I have reloaded the ghost image 5 times and the computer runs great for a day. But it will not boot again after a day. I have even swapped hard drives.
Any idea what the problem is?
