shutdown the computer by holding in the power button about 30 seconds. there are gears that control the movement of the tray of the cd rom, if it doesnt work after restarting just buy a new one they are not economical to repair

i dunno about the lock-up thing.. but the shutdown thing MIGHT BE the infamous remote procedure call error (RPC) (that is.. if u r using XP).. It would give a countdown before shutting down the pc. It is becos of a goddamned worm. Try running an antivirus scan to flush out the worm.

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

OK you do not provide a lot of information as to your system.\n\nFirst boot into safe mode by pressing the F8 key once the computer starts to boot. Choose command prompt only and see if it still shuts down.  If it does not that is good.  if it still shuts down, open the case and remove any expansion cards you may have installed except for the video card iof you have one.  Remove and put back in the memeory.  Look for lots of dust in the system also if there is a lot of dust then take the system outside and blow all the dust out with either canned air or an air compessor use care  not to blow too hard.  Pay attention to the poser supply.  After cleaning the computer out and reseating/removing all of the cards and memory restart the computer in safe mode and see if it stays on.  If so it is probably fixed.\n\nIf it still shuts down it is probably a bad power supply or the processor is overheating.  if you feel confident you can reseat the processor and replace the power supply.  If not ask the local computer nerd at work or a friend for help.\n\n\nIf the computer still shuts down it is probably something major.\n\n\nTo make sure a virus is not the problem just disconnect the power cable to the hard drive and boot the system.  if it will stay on but shuts down with the drive booting then there is a good chance you have a virus.  Do you have antivirus software installed and up to date?\n\nhave you tried system restore going back a week or so?\n\nRemoving a virus is a whole different question

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

Restart the PC. this kind of things sometimes happen.

You need to check that particular computer and make sure it is set to "shut down" and not set to "reboot".  That  will probably solve your problem.

It may get overheated or some hardware is broken (it can be a HDD,RAM,Video card etc., I think the HDD has a problem). Try getting a hardware diagnostic tool.

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.

Your problem is probably either a stick of RAM has gone bad (especially if it's the only stick you have), or it needs to be reseated (pressed down on both ends), or your motherboard's battery has failed, which is the most likely, given the age of the computer.

If your computer is not working properly while you are working on it, it could be a problem with device drivers, hardware or software. \nDetailed instructions at http://tinyurl.com/yk5zpr

There is probably an application that is not terminating when the computer is being shutdown.  Remove any programs that you do not need and try it again.  Also try closing any open applications manually and try shutting down.  If you hit Ctrl+Alt+Del, and go to processes you can see what is running.  Also make sure you don't have any adware/spyware running.  You a program like Adaware(www.lavasoftusa.com) to check.

You can work without restarting ...\nBut after 10-15 days you will face issues related to perfomance as the components of computer get heated up due continuos use...

have you tried scanning the computer for viruses and spyware? that's one reason.\n\nAnother is possibly that the capacitors in your mother board are bloated. That happened to ours and my father just bought new ones that matched the bloated ones and soldered them in. Now our computer works again. \n\nOR try to see if your memory cards connection thingy( sorry forgot the term) are clean. \n\nOr the cpu fan ain't working properly.

Likely you have a heat problem.\nor it could be a fan rotation warning, some motherboards can alarm you if fan speed drops below a set level....\n\nPay attention to it regardless, and have someone look at it !

This definately sounds like a heat problem. CPU overheats and the box automatically shuts down to keep it from burning out. If the CPU is still too hot that would also prevent you from restarting right away. It could also be the power suplly, but I don't know of any that have a connector so the motherboard con monitor it's heat. They may monitor themselves though, not sure. Next time you start it up, go into your bios and find a setting named something like "PC health" or "hardware monitor" depending on the bios version, and it should tell you there what the temp of your CPU is. Watch it for a while and see how hot it gets. How much heat a CPU can take depends on it's model, but around 70c is edging towards dangerously hot. If this is the case, you'll either need a new CPU fan, or the CPU fan is installed incorrectly. If you do need to replace it, or reseat it, do NOT forget to put thermal grease between the CPU and fan. It's an easy mistake to make if you're a begginer and it will fry your CPU. Either way, good luck to you.
