The most likely cause is that you have picked up a virus in an email and unless you have a clean backup of contents all is likely lost without expensive intervention at very high tech level within Microsoft and even then it may not work. Can you boot to safe mode? If so, try to run spyware to seach the disk. I'm not optimisitic that you'll be able to boot to safe mode even.

Do you have the rescue disk that came with the system? Try rebuilding the system, although you may well perpetuate the virus regardless of using the factory rebuild disk because it is extremely difficult to delete even with multiple reformats.

This could be a bad power adapter or bad power jack. If so, the battery will fail to charge. When you attempt to startup, the battery has too little charge and the system shuts down before fully booting. To check, remove your battery, plug your power adapter in and look for a panel light. Or, with battery in, look for a battery charging light. If no lights, your adapter is probably bad. Or, you could have a bad power jack.

SOURCE: Toshiba A135-S4527 starts to power up then shuts down.

When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a small brush and can of compressed airto do this.

SOURCE: compaq presario cq50-100em wont start up

I'm sorry to say this sounds like a system board failure. On my HP DV200t, a very similiar issue occured, eventually only the led where you plug in the power cord would turn blue. I replaced the system board and all the issues went away.
Hope this helps, and I am sorry to be the bearer of bad news.

SOURCE: monitor keeps shutting off after a few seconds- hp dv4000notebook

You may have a defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

I accidently shut my computer down with hibernation before leaving. When I come home, the computer will not turn on, no lights no noise, nothing. How do I unlock the hibernation? Or could it be something...


You need to hit the power button just the once to bring it back out of hibernation mode. It may take around 30 seconds until you hear your computer starting to boot back up and a little longer for the screen to come on.
Failing this, you can try a hard reboot by holding down the power button until you hear your computer re-boot. Usually you need to hold around 10 seconds. However using this last method as a final resort will result in your computer telling you that it did not shut down properly.

When i push the power button on my amilo xi1554 all the lights come on and you can hear it starting up but after a few seconds it shuts itself down and then turns itself back on and it keeps repeating this


i had the same problem and found it was a virus.
i had to reinstall the operating system and unfortunatly this meant losing all data on the laptop, but i was lucky that all was backed up on external hd.

HP Pavilion MD5020N 50 in. HDTV DLP TV keeps shutting down


ok this is what you do folks.... un-plug the tv from the power supply. once that is done hold the power button down on the side of the television for 30 seconds. this will release all electricity out of the tv.... then before you plug it back in hold the channel down vol up button along with the power button at the side on the tv this should reset the tv and it will start up automatically on video one. Select your source and scan for your cable channels again. If the problem is not solved then contact someone to come and clean the filter for the tv because it may be clogged along with this it can be the color wheel and may shut itself off like 3 times until it feels it is right.

Mac Mini G4 turns itself ON


Have you looked into System Preferences>energy saver>schedule? Maybe it's set up to start itself. I have my mother's mac set to start up and shut down automatically. Just a thought.

Keeps turning off


Sounds like a hardware failure. Possilbly the motherboard, more than likely, the power supply.
But then - maybe neither.
Shut it off completely, once you restart, start hitting the F8 key ( once a second ) until you see the " Safe Mode" choices screen. Drop down and select the " Last known Good Configuration" option and hit enter.
If this doesnt work, try the same proceedures ( restart - F8 ) but this time select safe mode - at the top of the list.
If you sucessfully boot in safe mode, you have a system file problem that could be virus related, file table corruptions or registry problems or all combined.
