Computer Restarts frequently

[gullducott]

There are 3 most likely causes to this problem.
1.) Least likely- your computer is overheating and shutting down to protect itself. >if this is the case make sure you have the hardware monitor utility installed this will first give you a warning that the temp is getting dangerously high and hence you will know it's the cause.
2.) More likely - Your memory is knackered or intermittently suffering from errors. it does happen, and often causes the pc to crash. If you have more than one memory dimm in your pc try alternating them or removing one at a time to to eliminate the bad one.
3.) Most likely - you powersupply is not up to the task of running your pc now you have added an additional peice of kit (your cd/dvd rom or whatever it was) once the components in the power supply warm up; normally takes about 10 - 20 minutes, they begin to exceed the safe operating temp because of the excess load; power supply shuts down. Typically you can't turn the pc on immediately but need to wait a few mins before it will come on (though not always.)

I have experienced all three of these issues and their symptoms in addition to one more I have mentioned, (but am about to) a faulty motherboard.

Good luck

mine use to do that all the time
found out it was something to do with my gfx card
it would run fine for about a half hour crash re boot then take its time to re boot back in to windows ... put a new card in and it goes fine now the card i had was a g force 4 mx 440 ... that card was dead from day one tho the fan on it use to make funny sounds when the computer would boot up lol

and i now have g force n card not the best but it does what i want
and it doesnt re start my computer every chance it gets lol
