    So I have sort of a unique issue going on here.

    Against all the voices in my head telling me to wait, the other night I got completely hammered then decided it was wise to clean out my computer with an air duster and ended up accidentally flatlined my CMOS battery, now after this I replaced it today and am able to get the machine to boot up, the only issue I'm finding now is it will not let me use anything for a monitor except something with VGA on my onboard graphics, (will not let me use the HDMI onboard, or any of the ports on my graphics card. the graphics card runs fine and works on my wife's computer (tested). I checked my bios settings and the card is selected, so I don't understand why I can only use the one VGA port on my pc. if anyone can help that'd be great

    Is this 'air duster' a can of compressed air - those are generally safe for use on computers.

    Did you drop or let the can roll around in it? You might want to check for loose connections , re-seat your memory and your video card. It would help if we had your system specs, •It is recommended that you download and run the http://static.techguy.org/download/SysInfo.exe and include the log produced in your post
