If it doesn't power up then:\n\n1.  power cord / wall outlet\n2.  Power supply\n3.  Motherboard\n\nThe first one is free.  The second one might be free, power supplies tend to go to sleep for a few min when abused.  However, a new power supply is like $40 and easy to install.\n\nThe motherboard is usually terminal these days.

couple of ways to see if it is a hardware or a software fault\n\nfirstly boot into safe mode - restart your pc and keep on tapping the f5 or f8 key then select safemode\n\nleave it in this mode for a while - does it shut down ?\n\ncheck your event viewer for any system errors (in the control panel - administrative - then event viewer) click on the system \n\nsee if this gives you any clues\n\nalso try getting into the bios or cmos setup - again leave it in this mode - does it shut down - if so then you definately have a overheating problem\n\nalso check you in you bios to see if you have a hardware monitor option - if so check the cpu, system temp and fan speeds\n\ncome back to us with your results

check if your CPU temprature is high.\nthe most common resualt of "CPU fan" problem is hanging or freezing.\ncheck if your CPU fan is working properly.\nthe next problem may be RAM.try to change RAM and test your system.

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

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

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.

might be that your cpu overheated....\n\ncould also be software issue..ie..spyware.\n\ncan also be your HD encountered bad error\n\n\nwhat am i trying to say?  that symptom alone is too generic.. could be a lot of causes

I had a similar problem caused by an overworked power supply unit (PSU) which was cheap to replace, but in reality it's not going to be possible to diagnose over the internet as it could be any one of a number of hardware or software issues.\n\nMy advice would be to call some independent PC repairers. Some offer a no fix no fee service & should tell you up front what the cost is likely to be.

You could probably overclock it to 2.2GHZ\n\nEither way if you try and overclock it too high, it will just shut down the computer due to getting too hot, just don't overdo it.\n\nIf you recently upgraded just  your processor. This could be the problem.

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.

We had what we thought was a dead monitor at the library I work at.  Turned out that the vga connector into the CPU was loose.  The tech jiggled the connection and the monitor came back on.  Hope I explained it correctly.

Your "system idle process" should normally be very high when not much else is happening - it's Windows' way of saying "this is the unused CPU capacity". As far as the light always being on, it may be a software issue. When in doubt, take the machine to a PC shop or trusted friend whose day job is computer repair, and ask them to check for unwanted programs.

Take it in to a shop and have them look at your power supply. It sounds like that could well be your problem. If so, it is a fairly easy fix. Trust me, it happens way too often of late. Good luck.

I had the same problem. Is was an electrical surge from my power source. Caused by  the fan motor in the processor. I had the motor replaced and it is back to normal.

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.

check for viruses (specially when your system booting after connect to internet ) \ncheck power voltage \ncheck  cpu fan \nreinstall win xp \nif cpu fan is good

Could be that it was jarred and an internal component is not seated properly.  If you are comfortable with doing so, you can try reseating the memory, hard drive, wifi card, etc... to see if that fixes the problem.  If you are not comfortable doing so, take it to someone who is.
