Hi, need a bit of help desperatly,my brother was on his Packard Bell (sorry i know it's not home built couldn't find anywhere else decent to post this topic!) pc earlier 2day and he reckons it just totally went off and now it won't turn back on again, their is power going to the tower unit with the red L.E.D symbol but nothing shows on the monitor or anything The fan and power supply seem to be the only components working!,doesn't the red L.E.D suggest it's a hardware fault such as gfx card? i suppose it could be a virus also as i recently changed his anti virus software,any suggestions would be appreciated, i've turned the power on and off etc,the model is a istart model i think bit unsure of spec as it isn't my pc! The DVD Drive won't even open etc either. Please help!
