If you mean the electric power shutoff after one second,,then the problem is in the power supply unit,, it is not expensive

check your CPU fan when you turn it on. If it isnt working it will shut your system down.
Well, IS it overheating? That might be handy to know.
Please check whether you have sheduled some shutdowns. Also run a virus scan to make sure that there is no virus infection. Use AVG to scan.
change the power supply..disconnect it down to the power supply, video and board and reconnect cables one by one..its either the power supply or a conflict...many times its a bad drive or floppy on an older computer.
Nope....

i have experience that too!!!

it is a virus infection!!!

i have to reformat everything!!!!
