Re: Help 2005 computer not working
If you mean that it kept restarting, this is a sign that the bios is corrupt and you will have to remove the side of the pc tower and on the motherboard look for a 2 terminal commector, this can be labelled CLRCMOS, CLRRTC,or a 3 pin JBAT1, there will be a plastic cap if its a JBAT1 terminal, put from pins 1-2 to pins 2-3 then back again, if its the others then they have to be shorted by placing a cap across the two terminals.
restart pc and press f2 to reset time and date and save and exit, it should then boot back up.

as much as i want to help you, there is too many cables inside a computer and i dont know which one your referring. as you said everything is unplugged we can make it work but that is complex discussion to start with
Please turn off the computer, start hitting F8 at the start-up and then
choose last known good configuration. If this does not work, choose Safe
mode options. If still does not work, please try to restore the computer to factory settings. You can try to hit F11 or F10 at the startup to initiate recovery. If not working, please tell me what error message you get on the screen.
If you mean you didn't get any display in your monitor the first solution is u must reinsert your memory and memory slot.if still have the same issue confirm your monitor is connected to your tower properly.if you still have the same issue just replace your memory (ram).thank you.

3. remove battery
4. press power button and hold for 10-15 seconds

HP/Compaq has had alot of power supply issues with this series of computers. Do you have another power supply you can try in this system? If the light is flashing rapidly, it is usually a power supply. Fairly cheap and easy to replace.
try to start the computer and right after that press the delete key several times as it try's see if u can get into the system bios if so change everything to a default level make sure you pres the f10 to save all info and try to reboot if this doesnot work please let me know good luck
