Sporadic On-And-Off

read300300 · 01-12-2007, 12:19 PM

I have a Compaq Presario PC (bought it the beginning of 2005.) Yesterday, it crashed. It started out with the monitor cable not reading the hard drive, so we unplugged everything and replugged it, thinking that it would fix it. When I plugged it back in and turned it on, the hard drive decided that it can't get enough power to start. It tries to start and fail. I can't tell if the monitor cable is working or not because the hard drive won't stay on.

One of my friends who is technically capable to handle most problems said that my motherboard is getting power, but that it can't maintain it. There are no visible jumpers and clearing the capacitors did not help at all.

I would really appreciate it if anyone could help.

Are your system fans also running a sporadic speeds. If not I doubt you have a lack of power just to the hard drive. When you plugged everything are you talking about from the back of the machine or everything inside also? Chances are you might have forgot a plug.

The fans are running sporadically, coinciding with the looping on and off. I only unplugged the outside ones; I don't mess with the inside of my harddrive since I'm not that well-versed in hardware as of yet.
