why my computer keeps on restarting during low power supply?

This is because your computer's power is so low that it needs to keep restarting to prevent the battery from dying out.  When it restarts over and over again, less power is utilized.  If you don't have any way of restoring power to the battery, you should just continuously save your work every several seconds.

are you getting power or not. i would first check all the cables to see if anything are loose. i would also check the power supply. and also would look in you motherboard book to find how to reset the bios.

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.

Yes,sounds like over-heating of the power supply unit.It was switching itself off every time it got over-heated.Most probably the cooling fan inside the power unit was not working.

Hopefully you have not shorted your motherboard. If you havn't then replacing the SMPS (power unit) will do. Otherwise, you are in for a lot of expense. Buying a new motherboard.

Your "system idle process" should normally be very high when not much else is happening - it's Windows' way of saying "this is the unused CPU capacity". As far as the light always being on, it may be a software issue. When in doubt, take the machine to a PC shop or trusted friend whose day job is computer repair, and ask them to check for unwanted programs.

because the computer uses a little battery on your motherboard instead of the powersupply

If you are getting no power to anything then something is wrong with your power supply.

You need to enable Advanced Power Management in the bios setup. \nTry the link below for details.

Quite possibly it is because the power supply is overheating, and the outside power supply fan should ALWAYS run. Since it is not there is definitely a problem with the P/S. I have found that the three major causes of unexplained reboots are due to faulty power supplies, RAM failure and general overheating that is not due to technical failure.\n\nYou might be able to buy a power supply testere for about $15 at your local computer store (Radio Shack MAY carry it, but a CompuUSA or PCClub should too). Otherwise I would either replace the power supply, or replace the outside fan in the power supply and see if that works (make sure that the connection types match on the old/new fans).\n\nWhat you could do before all that is to just leave the side of the computer off and see if it still reboots, and if so then it is not an overheating problem, but could still be the power supply.

If your computer is making a noise when it comes out of standby, then that is probably your hard drive restarting. The hard drive is shut off during standby.  It's normal.\n\nAs for why it's taking so long to think, then I agree with the others.  More RAM usually fixes that.

Depending upon the frequency on how much you turn it on and off in a given time. The newer PCs motherboard does not completely shut down, but goes on deep standby mode, much of the power, even just a trickle, is applied under this condition through the boot sensing channels handled by the bios and accompanying chipsets and sub circuitry without supplying power to the major areas until needed, including the main CPU. any abrupt powering on and off may contribute some possibility of failure, but not necessarily immediate, and may take some time to evidence itself. The switching mechanisms had changed from basic mechanical to digital pulse actuated SCR transistors that are quite susceptible to voltage spikes. The most concern will be noted at the power junction between the power unit and the power interface circuitry on the motherboard. On these aspect much consideration really rely on the quality of what these components are made, and how the circuitry is designed entirely. Therefore, the quality of the components may have a real bearing on the possibility of any failure by repeatedly turning your PC on or off, that could cause a voltage spike at each transition.\n~meow

The main reasons for restarts: 1.bad memory 2.overheating (can either be processor or chipset)   Yours sounds as if it's your processor overheating, though, since it's usually happening when you're using your processor at or near 100% usage.  \n\nTry turning it on, then going into the BIOS, and check your temps there.  If it's idling much above 50°C in the BIOS, then that's almost surely your problem.  More than likely, you just need to go to Wal-Mart, and buy a can of compressed air, and blow all of the dust out of your heatsink.

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!!

Two most likely culprits:\n\nPower & Heat. \n\nFirst clean out your computer. Get rid of the dust, clean off the fans. \n\nIf that doesn't work buy additional system fans.\n\nIf that doesn't work replace your power supply with a larger wattage one.

there shoudl be a restart button on your cpu.  try that

Restart the PC. this kind of things sometimes happen.
