no power response on PC-sony vaio
I have a problem with the power of my pc. I switch the power button on, it lights up for about a second and shuts down automatically. I have tried using three different power cords for the pc-tower and I continue to get the same result. This is very unusual because I dont use the computer excessesively or on a daily basis. The pc system is just about 3 years old and I have not been running any internet on the computer for the last 14 months.
I mainly use the computer for managing my MP3's and use of Microsoft Office for school projects. I used the computer about a week ago and everything was working properly. I am confused as what may have caused this power failure and where I should begin to fix it.
Unfortunately, my warranty on the PC just expired a while ago and would like to get some feedback on this situation before I take it to a computer repair shop.
