if you have NO screen activity (ie no cursor, or post test) then your problem is probably video card or mother board related. you most likely will not be able to fix this yourself. take the tower to your favorite tech for diagnosis. the diagnosis shouldn't cost much more than thrity dollars US. the down side is you may be paying 30 bucks to find out your motherboard is fried and you need a new computer.\n\nsorry about your dilema.\ni hope im wrong\ngood luck

try CPU (processor) cooler there is an sensor under the cpu socket on the mainboard so when the cpu gets hot it turn`s off the pc and wont turn it back on until it gets cooled down,since you power it manualy

Unplug any or all of the USB devices and restart.  See if that helps.

If your power supply is faulty or your processor fan is broke your PC will shut down to cool down, but wouldn't necessarily start up again.\nIt sounds like a virus or worm infection.  I would try going into windows in safe mode (F8 function key normally) and see if the system continues to close down.\nIf it is stays on o.k. check you haven't installed a driver or software recently that may be conflicting with Windows.  If this happens you should be able to roll back the driver or system restore to a point where you know your PC was o.k. (In F8 this is the "Last known good configuration")\nIf it shuts down again it may be a virus, have a look on symantec's site for a hotfix for the latest virus/worm,if it is a virus you'll proably need to disable your system restore whilst trying to remove it.  Follow the instructions to remove it carefully so not to destroy your pc further!!

Check if you have all the correct drivers installed. You said that the PC had recently been formated so it could be as simple as incorrect video or mouse (trackpoint, touchpad) drivers.\nYou should check the manufacturer's support site to get the latest version of drivers. If you don't know the address just post your make and model and we'll try to find it.\nHope this helps!

If you have backed up your important files (hopefully) I would suggest reinstalling Windows. If you have important files or email that you have not backed up then I would suggest calling a local computer repair shop and tell them what is going on. The processes we use to get a pc back up and running would take a long time to explain in a forum like this. It can take anywhere from an hour or more to get a computer backed up, cleaned of spyware and viruses, windows updated, etc - it is all dependent on your pc and what is going on with it - there are no easy answers.\nIt could be a hardware problem, but software problems are 10 times as likely. Good luck.

restart your computer\n\nif that doesn't work, de-install it and re-install it again

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

If the machine is open use the following standard:  \n\n1). Always check connections first (remove and reinsert) - keyb, mouse, usb, video cable (all outside).  CPU chip, memory chip, video card (and others if present), power to motherboard, fans, reset or power button stuck, data and power cables to devices.  \n\n2).Follow (within limits) process of elimination:  If success add next most basic thing and continue until failure.  Move cards and memory to different slots as a quick test.  Remove everything but CPU chip and power to M/B.  Beep test - power up and listen for series of beeps;  no beep=check CPU, M/B or existence of  beeper/speaker.   Add memory, beep test.  Add video, look for output.  \n\nAt this point, test the hard disk LAST so it wont boot windows or be hammered for every test.\n\nAdd a power cable to floppy and test.  Add a data cable to same device and test, then try to boot a floppy.  Add power to next device, test, then add data to the device and test - etc.  Then add each card until failure.  Any failed item should be thoroughly checked out unless you're rich and will replace it then and there.  Sometimes certain M/B will not power up or boot without CPU and memory chip combo.  Some are intelligent enough to allow only CPU.  \n\nIf you are uncomfortable with any of this, take your box to a PC guru friend or a service and have them do a flavor of the above.  Don't let them tell you the thing is hosed - make 'em show you something from the above or similar tests.

What have you done recently ?(i.e. reinstalled driver, etc.) these answers would be necessary in helping you diagnose the problem

I had a similar problem.  I didn't take it to a PC doctor, I just buried it and played taps.  It was three years old and did fine for me in that time.  Now that I bought a new processor, perhaps I'll dig it up and see if anything can be done.

PLEEEEAASEEEE, update windows; take it to the nearest techy... if you are getting a real bad problem (which i think it isn't because windows is starting up) just buy a new computer, u can get a good one for about $200 nowdays that'll suit your needs

There may have been catastrophic damage to your system. I suggest backing up your data and reinstalling Windows off the OS disk that came with your computer.

if it happened recently try system restoring it back to before it started. Click START - All Programs - Accessories - System Tools - System Restore. Then as i said restore it to the point at which you think it worked.

shut down and return?\nOr leave your computer on and return? It could be a whole host of problems. Thats not enough information to really go on.

Try restarting your computer.
