Well i have a serious problem. My computer randomly restarts on its own. Well what really happens is the computer will restart and i will not be able to move the mouse. Than all of a sudden my monitor screen goes black and the LED light on my monitor goes from green to orange and the computer screen stays black. I just reformated and this problem still occurs. The computer performs perfectly fine. I just recently went into the BIOS settings and looked at my temperature and noticed that my computer cpu and mother board was 30 degrees Celsius 86 degrees Fahrenheit. Than i just looked at my CPU fan speed and my PowerSupply fan speed and it said that my fan speed was going 4k rpm and that my powersupply fan is going 0 ....weird hey? But its moving. Maybe its that my motherboard is not detecting my powersupply. and maybe it is time for a new powersupply. Well i will have to do with the computer restarting than. and eventually the computer will restart to much and the powersupply will burn out than it will be time for a new power supply. I will get one than. I am a computer technician and i do not even know what is causing the computer to restart. The computer restarts like randomly but usually every 6 hours or so.. One time my computer froze and the screen went back and than it turned back on and the graphics settings were messed up. The computer was extremely BRIGHT! the task bar, desktop EVERYTHING so i tryd to go into my graphics control panel but it says my graphics were reset or something like that.I took a screen shot but when i sent it to someone they didnt see it only i saw it so i was gussing it has something to do with my graphics card.. Anyways any help what so ever would be greatly appreciated..

thx
