Ok so a friend of mine built a computer for me and a year later it started to act up. everyonce in a while a message came up saying fan chipp error...then the same friend just turned the warning off so it would never come on again...then eventually i would try to boot it up and i wouldn tget any beeps and nothing on the monitor....turn it off turn it on it would boot....after two years of it sitting i got it out again last night and tried to boot it...nothing...tried again and again ...nothing...then it booted for me no probablem...then again the next morning and now its wont do anything again...ive talked to other DIFFERENT friends that no a bit about computers and they have no idea what is wrong with ir....any suggestions would be helpfull...thankyou
