Solve : Video Card not being detected... sometimes! please help? |
|
Answer» I have a x1900 pro VIDEO card and an Emachines computer with an onboard geforce 6100. The ati card worked perfectly fine for a couple of months.. than one day while turning on the computer i noticed the monitor wasnt turning on. WHen i plugged the monitor into the onboard vga output i realized that the computer was running now on the onboard video card. When i restarted the computer a couple of times.. the x1900 "turned back on" without switching anyting in bios or updating any drivers. So now.. whenever i have to shut my computer off.. sometimes the x1900 is detected.. and sometimes the on board card. I dont have an option to disable to onboard card.. tried reinstalling ati drivers.. reinstalled the card itself.. i even formated my HD and upgraded from XP to Vista.. and still have the same issue sometimes the card is on and sometimes the onboard card takes over.. Please help as this is very frustrating and i cannot find any solutions to this problem.Quote WHen i plugged the monitor into the onboard vga outputWhy, if you have VGA jack in your video card? Quote a x1900 pro video cardWhat brand is it? Then...if you want to use your video CARD, then on-board video must be disabled (Control Panel), and your monitor has to be plugged into your video CARD VGA jack.I only have the monitor plugged into my onboard card when it does not turn on while its plugged to my ATI card.. if I do PLUG it into the card it does not turn.. That is how i KNOW which card is working after turning on the computer.. i switch the cable between both VGA connections (onboard card and ATI card) Disabling the on board video card in the Device Manager doesnt do the trick.. my ATI card is still not being detected and the computer still runs on the onboard card.. in minimal resolution (default driver). The card is a ATI Radeon x1900 GT (not pro sorry) 256mb PCI EXPRESSIF you go to Control Panel, is your ATI card listed under Display Adapters? If not, can you see "Other Devices" folder open with some entry displaying yellow exclamation mark?No only the on board card is listed.. and there is no Other Devices tab. Its as if the card was not even there.. Im starting to LEAN towards a faulty motherboard or the pci-e slot being defective. Too bad i dont have anywhere else to test the card out. The odd thing is when the card DOES turn on.. it works flawlessly untill the next time i turn the computer off and than its gone again!Couple of things.... Do you have another PCI slot? I guess, not. Turn your computer off. Remove your ATI card. Restart computer. Disable your on-board video in Control Panel. Turn your computer off. Put ATI card in. Start your computer. Does it go to Windows? If so, is your card listed in Control Panel (Display Adapters, or Other Devices)? |
