A few days back... When I was running the PC... It suddenly went off... I couldn't find anything wrong... And after I removed my graphics card and plugged the VGA adapted onto Onboard Graphics, It started working just fine... But then when I installed my card again, It just won't work... Please Help!!.... It was working fine for the last 4 months...
The GFX card's fan is spinning but it won't give any signal to the monitor via the VGA port....
Card : Sapphire ATI Radeon HD 5670 [No Auxiliary Power Connector] Mobo : DG31PR OS : Windows 7 RAM : 4 GB DDR2
