Afraid it's gonna be a trip to the computer shop. I'm out of ideas anyway.
Maybe try an other gpu or if you have one use the integrated video see what that does.
So much possibility's here which can cause the problems. I think it's a loose cpu or gpu because of the kicking, maybe even a crack in the mobo, but who knows, maybe it's only a loose connection or what ever.
The truth is i don't have enough time to take it to the shop where i bought it,so i just took it to some guy and he told it was the problem of video card,this is thsecond one-i have some iball psu and when there is a power cut i used to run it on inverter with a 54"TV running simultaneously so i think there wasn't enough power at all(kicking has no effect,probably) the nest day happened to be the problem i mentioned 'above'-(it was probably a coincidence),i replaced my video card with a cheap one and it worked fine until the power went out again and I wasnt even able to open the computer now AT ALL(no power supply),so i just borrowed a better PSU from my friend and it worked just fine but the same 'FAINT BEEP' starts and randomly screen goes blank without 'NO SIGNAL' when i connect my old graphic card but still runs fine with cheaper one,So i want you guys to finalize 1) is it not enough power
2)And is my graphic card gone forever??(i have a warranty)
3)Can i do something with my card....
Thanx in advance and please help me
