Cycles through power up, but then shuts off. My wife previously stepped on this computer and cracked the screen, which still operated. I hooked it up to my desktop monitor and used it that way for some time. I recently purchased a parts computer of thesame type which had a good screen. I changed out the screen, and when I powered it up to check it, the computer cycled through and windows began to start up, but it suddenly shut off. I started it again and it did basically the same thing (it seemed to not shut off at the exact moment while cycling through windows as the time before). I started it again, and it kept shutting of. The place where it shut off did not seem to be exact, but the shut off, did get quicker. At times it would not even get to the windows logo, but was merely at the bios option. I tried using the battery from the other computer (which was reported bad though) and it kept turning off. I had the computer plugged in every time too. The original battery was not holding charge, but the computer was working before, as long as I had it plugged up. I would appriciate any help or ideas as to what may be the cause of this mystery. Thank you and God bless. ><>
