I was wondering if anyone can help me.
I cleaned my PC yesterday of dust and now nothing is displaying - No display would come on the monitor.
The motherboard I use is Biostar TA970 and the graphics card is GT610 (WITHOUT FAN)
The graphics card is working because you can feel the heat.
Their is also nothing wrong with the VGA lead as that works in another PC
I have tried it in my TV that runs HDMI and nothing still.
I think that it has disabled express PCI in bios but I have no idea how to get to the BIOS if I cannot get a display.
You might have moved the video card so the contacts now fail to carry the signal. I suggest you unplug the PC and remove the video card, clean the contacts with a new pencil eraser and re-inset into the PC. If it doesn't work on the next restart then you might have a motherboard problem.
PS how did you clean the dust? I hope you just blew the dust out and did not touch any of the cards or motherboard.
