ive seen that happen with a bad motherboard battery ... try popping the battery out WITH THE POWER OFF (unplug)... then put it back and just see ... u could possibley have to go back into bios settup and load defaults depending on the pc ..\n\n.. and yeah ... make sure the jumper is on cable select or slave in the back of the harddrive and plug it into another pc ... if its an ide drive with the thick ribbon cable plug it in the middle connector of a ribbon cable in another pc...

if the tower is all working (light is on and display is showing on monitor) then chances are the OS is damaged. recover using the recovery disc or in some cases using the resest config data option in BIOS

This sounds as if your power supply on the PC itself went bad.  Especially if you have checked all your power connections, and you are still on getting power to your system.  \n\nyou may need to contact E machines and see if your system is stll under any warranty.  If you have any Geek friends, have them check it out to make sure its the power supply, and not the motherboard, memory, and/or processor.

reseat your hardware fist but you may have a conflict with your hardware, first try updating your Bios, if that no good, see if your button on your pc is not sticking,  if it still dose the same remove your cards and unplug your HDD, Cdrom, dvd and so on until all of them are removed, take one out then turn the pc on to see if that works . if still no luck it might be your power supply.

first check led of power of cd-rom is glowing or not.\nif not then check the power supply of drive. \nif it is glowing then check databus of drive and check it's connection in motherboard.\n\nthen it is not working then repair the operating system.

There could be quite a few problems, but this could also be a fairly simple fix.  I would first try to just unplug the whole darn thing, wait about 30 seconds, and then plug it in again and try to start it.  Seeing as you have internet access, I would also try going to this website: http://h10025.www1.hp.com/ewfrf/wc/document?docname=bph07173&lc=en&cc=us&rule=14694&dlc=&product=396431.  That hopefully will help. =)  Good luck!

Try rebacking everything up again. This time DO NOT touch the power buttons or anything else just let it finish the job at hand...Thanks

are you getting power or not. i would first check all the cables to see if anything are loose. i would also check the power supply. and also would look in you motherboard book to find how to reset the bios.

Somethings to do will be;\n\nOpen the computer and check all cables and connections\nRemove the CMOS battery to reset the Bios\nDisconnect any hardware that you don't need to boot up\nTake the Ram out and then put it back in\n\nIf none of this helps then it is either a power supply problem or the CPU is blown and the only way to find out which one is to remove it and test it with a working one.

PSU failure, where the volatge exceeds ~8.5v. Check the keyboard connector to make sure it's clean.\n\nHave an experienced person look at it (don't pay to have it serviced until a friend says so, that's just stupid)\n\nUsually the fuse connected between the power and the keyboard connector would blow out before the keyboard would.

It is possibly overheating. Check the fan. Check power supply, it could be going out. If not:\nYou probably need to reorder your BIOS by hitting del on startup. If you dont know how to do this please dont try, get help first.\nHere is a search of this problem, choose one of these forums that seems most similar to your system and ask them. They should be able to help. Its hard to troubleshoot a problem on Yahoo Answers as we cannot easily have continuous dialogue.\n\nGood Luck!\nhttp://www.google.com/search?hl=en&q=computer+restarting+over+and+over

check to see if any other appliance works in those sockets. If the socket works. It sounds like the power supply may have gone bad in the computer

Check the battery..Go buy a new Battery.. See if it boots up then..If it dosent then it looks like a computer doctor is needed.Could be costly. If its an old one. it might pay you go buy a newer one.

Make sure it is plugged (sounds funny I know but make sure).\n\nNext, make sure that you did not accidently bend any of the pins on the plug when you plugged it into your computer.\n\nIf still nothingit is probably toast :(

This can lead to two things.\n\n1.  Power supply is gone\n2.  BIOS is gone

Check the fans and make sure they ALL are working. If you have a CPU temp utility, use it. Try starting in safe mode and see if it is still happening.

so the power sign is green, but when you turn it on its just black? well all your screen is is a monitor connected to the cpu, so you might have power failure to the monitor, but not the cpu. its the same as when your tower is on but the screen is off with a desktop.
