Hi Gaunty. Okay, please provide more information than that when you post. The information you gave us so far does nothing to help anyone troubleshoot a problem for you.- What are the exact specifications of your computer, including Power Supply rating? (You can find the PS rating on the inside of the computer on a sticker on the side of the Power Supply)- How long has this problem been occurring?- Have you recently installed any new hardware?- Do you hear any beeps during startup?- Do you notice if any of the fans are spinning?- Do you see any lights on the computer or on the motherboard?

ok my specs are -motherboard: gigabyte ga-m55 sli-s4-cpu: Amd athlon x2 3800+-RAM: 1GB DDR2 800-HHD: 160 SATA-graphics: geforce 6200se-power supply: 500wi have not installed any new hardware.it does one beap on start up.all of the fans are spinning and all of the lights are on.

Great. I forgot to ask you probably the most important probing questions.- What are you normally doing when the computer restarts?- I take it this is a custom computer so do you have the motherboard system monitoring utility installed to monitor CPU, motherboard, and internal temperatures and Power Supply voltage?

[gaunty]

it usually just restarts at any time even if i have not logged in yet

Okay, my first gut feeling is an overheating problem caused by either a faulty Power Supply or potential hardware conflict/failure.I take it you do not get any error messages, correct? If you do not get error messages, I would first try by getting a BASIC Power Supply. When I say basic, I mean 400-450W, nothing fancy or elaborate. At this point you are only going to test the new Power Supply.Once you get the new Power Supply, fully install it into your computer and restart the computer. I would advise running the computer 24 hours a day for as long as it takes to either confirm or denounce a Power Supply failure. If your computer normally goes two days between restarts, let the computer stay on for three days until you are convinced that the computer will not restart on its own.Also, I mentioned the motherboard monitoring utility in my previous post. If you have not installed that application, I would strongly advise you install that and monitor the temperatures of your computer.Now, if you DO get error messages, please provide the EXACT error messages you get so we can try and narrow down your problem.

NO there is no error message thank you for your advice.

My Pleasure. Please keep us informed as to your progress. If, after you install the new Power Supply, you still get random restarts, post back and we will take further steps.:-)
