My laptop keeps randomly turning itself off. There's no warning, no blue-screening or anything - just 'pop' and the power's gone. This happens in Safe Mode and command line bootup, but never in normal mode. I'd originally been having trouble with malware (the 'Internet Security 2010' thing), and ran several scans in safe mode to get rid of it; these were never a problem. After removing it, however, and having some trouble with other minor malwares, I tried to scan in safe mode again. Each time it would get a few minutes into the scan and then 'pop!' - gone. There's never any response to the reset when I roboot - no ''your computer reset unexpectedly so we'll run a scan'' message or anything (I run Windows XP some edition, for reference). As mentioned above, this never happened in normal bootup: I could run scans all day with no problems. Not being able to get rid of the malware, I reformatted with a 'Killdisk' program that completely wiped and reset my HD. However, my computer still keeps turning off whenever I try to reinstall Windows or run other scans. I twice tried to reinstall Windows straight after using the killdisk, and on both occasions it turned off within a couple of minutes. I left it for half an hour (suspecting overheating) and tried again. This time it got much further, managing to start a drive format before once again dying. I have taken the laptop apart to clean the processor vents and fans, but they were already clean. The fan appears to be in good nick and isn't lagging, whining or failing to come on. The processor was somewhat lacking in thermal paste, so I cleaned it and reapplied a layer. After all of this, I restarted and ran a RAM-scanning program, in case the memory was damaged, and left it to run by itself. I returned about three quarters of an hour later, and it had once again shut down. Could anyone help? I have read on some forums that it could be a problem with the BIOS reporting an incorrect processor temperature, but I'm nervous about trying to flash my BIOS on a randomly resetting system. Any advice would be much appreciated, as the only thing I have left to try is swearing at it.
Haven't yet tried booting from the cd to command prompt - however, I did try turning it on with nothing to boot from and letting it sit idle. Although it was doing nothing (as far as I'm aware, at least, heh), it switched off after about half an hour. The processor fan cycled up gradually over the course of the time on, adn by the time it turned off it was warmer than I would have expected an idling computer to be... but then, I don't know what an idling computer's suppsoed to feel like temp-wise :)
I'm gonna try booting into repair mode and the command promt next - I'll let you know what happens.

Swearing at is less gratifying as using the computer as a curling stone ... I have been experiencing some wild and random events with systems that had the 'Internet Security 2010' thing infections but not after a clean start if you use the windows cd to boot the unit an go to the the repair option bringing the system to a command prompt then does it 'pop!' - gone?Swearing at is less gratifying as using the computer as a curling stone ...

Please tell us the FULL brand number and model number of your Acer computer. Then tell us the happenings from the time you turn on the laptop until the blue screen shows. Then tell us what the blue screen warning says.
Is the fan and vents free of dust? Is the laptop getting sufficent air flow? It sounds like power issues maybe multiple issues. Does it overheat? Difficult to say for sure. If your remove the battery?
there are 2 tuners in a rear projection tv. maybe the main tuner is faulty or the tuner's associated circuit has problem. if there is no signal these tv are programmed to turn the power off/stand by.
That is the OSD (On Screen Display) system built-in to your computer monitor. Check that when you hit the ON/OFF button on your monitor, that you do *NOT* hit the 'OSD ON/OFF' button.
Most of the time, the OSD will disappear after 10 seconds of "non-use".
If that is the case your system need to check the battery for fault and does it happen with the power source too i fthe same problem check your processor fan if its bad when you on the system and is not blowing that might have cause the processor itself to get bad you will have to change this ones and then your system will be ok right rate this solution.
The blue screen of death gives you an error code accross the bottom of the screen. Something like Stop: 0x0000........
go to microsofts website and on the search bar at the site type in the code beginning with Stop.....Microsoft has causes and solutions for the codes there.
If you know the code please post it. I may be able to better assist you with the code or error message.
