When I turned on my desktop today, it only ran for about 2-3 seconds and then shut down. I tried again and again, then unplugged it and waited, plugged it back in and still, it shuts downs in 2-3 seconds. I have never had any problems with this computer before in the several years that I've had it. Please help! MaryS

Check the fan (top rear of the computer) , make sure it runs when you start the computer. if it is NOT running the power supply may be the cause.
also you may need to remove the case and inspect the fans inside. you shoulkd be able to remove a couple phillips head screws on the back of the computer and lift the cover off or at least the side making the guts of thhe computer visible.
once open , inspect all the fans and cables, especially the fan on the main board and the metal piece with fins undernieth it, this tends to collect dust causing the cpu below to overheat and shut down the syatem to protect itself. The number one cause of crashes is overheating.
look at these things to start and post your findings and we'll move on to another step.

sounds like your windows installation took a hit, try booting from the windows cd into the repair console and do a chkdsk /F /R; a fixboot and an fixmbr command. if ths doesn't work, try the repair option. You can also try to boot from a hirens boot disk and try the tools that come with that.
Hold down the power button on your monitor, with the power on, for approx. 25-30 seconds and the monitor will shut down for good. When you will start it again, wait at least an hour, the message will be gone and the monitor will work as intended.
Good day, The shut off is due to the protective overload mounted on the side of the compressor to shut it down, if it can't start. On the side of the compressor is a cover box that contains the overload device, a start relay, and on some models, a start/run capacitor. These items can to a degree tested with an ohm meter, but it is wiser to take them to an appliance parts house for testing. If any are found defective, replace them. If not, the compressor has failed internally and needs to be replaced. Close to $400.00 if not more.
set has a self diagnostic---after set does shut down press and hold MENU AND DEVICE(INPUT) buttons on front of set for 5 seconds----if 2 blinks, a pause and 2 more blinks: this is short protection error code---The set does use 2 Stk394-250 and each is protected by a pico fuse in the power supply---if either fuse is blown the set will shut down(it detects no voltage or missing voltage;) It is not uncommon for a shorted IC to cause this problem; if you locate the STK's look carefully at the resistors around them---if any are discolored or burnt---you have found your problem.
please try if this helps:
1. Remove disc from tray. 2. Switch off player and unplug from mains. 3. Wait 30 seconds, then reconnect mains. 4. Turn on player with remote. Wait for player to finish loading and display 'no disc'. 5. Press enter on remote. (There will be no on-screen response.) 6. Press 8, 4, 2, 6, 9 on the remote. (There will be no on-screen response.) 7. Press enter on the remote. Player will automatically shut off. 8. Turn player on. 9. turn off. 10. Turn player off then on again. 11. Player is now region-free.
Sounds like you have a heat issue.
Is the fans clear, or are they clogged with dust, hair, etc? Check the cpu heatsink as well for dust, etc.
It sounds like the cpu thermostat is shutting the system down.
Let me know
