UGH!! Borrowed some 'proper' screwdrivers. Since using a table knife to undo them, horrified my mother !! Took the casing off. Vacuumed the inside as best i could. Pushed as many plugs as i could see to make sure they connected. Shocked myself !! Swore ! Turned off power !!! Put the casing back on and did it up. Powered it back up. Fan ran very fast for about 20 seconds then died ! Loud 'PING' noise and the volume was back !
try turning it on lol. maybe your fan is broken or clogged up with junk. try cleaning it.

turn power off open the case unplug the mini=plugs on the board here and there and all over but one at a time and then plug them again if that doesn't help hit the pc with your 6 inch stiletto heel
