computer keeps on rebooting

My computer continually restarts itself over and over again. It doesnt do it at the exact same place everytime. Sometimes it does it during bios and sometimes it does it during windows loading up. I have checked for viruses and I have checked the temp and there both fine. This has been a problem for a long time because it used to restart randomly every once in a while but over time it started doing it more frequently but now its at the point where the computer has become useless because it never loads up. Anyone have any suggestions what the cause of this could be?
 
It could be your power supply... temperature is getting high... how many watts is your power supply? and do you have a solid heatsink on your processor?
 
I had this problem and believe it or not I had set the usb to on (or somethinkg like that) in the bios. I changed the setting and it stopped. This may be worth checking.
 
This could probably be an over-heating problem. Check your case and cpu temperatures in the BIOS and post them here. It could also be faulty RAM as well, but you would hear warning beeps on a bootup.

Could be your power-bar - it took me three hard drives to figure out that my 12 year old power bar was causing my drives to die...
 
Sounds like ram, heat or voltage fluxuation. Get MBM and record your voltages and temps for a period to see if you have bad fluxuations. Test the ram/cpu cache with MemTest86+ to verify stability.
 
If you want to check on your voltages, you can use this industry standard listing as a guide with a multimeter. Just remember that if you have good power, but dirty power, you'd need an ocilliscope for that.

ORANGE +3.3 V
YELLOW +12 V
BLUE -12 V
RED +5 V
WHITE -5 V
BLACK GND
GREEN POWER-ON
GRAY POWER-OK
PURPLE +5 V STANDBY

It would be easier to swap with a known good supply to see if it's your problem... It's where I'd start.

i hate to be a pain and ask the same question twice but how can i test it if it doesnt even start up so i can install the memtest86 thing to test it?
 
Start with what you can check first. Check your PS then go from there. You could always plug the ram into another system and see if the same problem pops up. If it does, take the ram out and get new memory.

Remove all of the PCI cards, internal drives and external peripherals that you don't need. If it works you have narrowed down the problem to one of those pieces of hardware or a weak power supply.
