*bumped for urgency*
I'm having some serious trouble with my rig. Specifically with the graphics card/display.
Occasionally, when I try to start the computer, the basic boot screens will show normally, but as it begins to load Vista, the screen will flash black several times, as if my monitor isn't getting any signal from the graphics card. It'll flash black a few times, flash green bars across the screen, and then just go totally black before saying it's not receiving a signal from the graphics card. Finally monitor's power light will then begin flashing orange, in it's "on but not receiving a signal" state
The good news is that, as far as I can tell, the computer's starting up just fine. The bad news is that my card and my computer are getting old. My card is a nVidia GTX 260, which has been discontinued, so I can't just buy a replacement. My PC is a Shuttle barebones kit, and the list of compatible graphics cards is rather long.
I've tried updating the drivers several times, and the problem just returns. Like I said, it only seems to be an issue with the display when I start up, nothing else has a problem. Should I just grab a compatible replacement card? Would that fix the problem? Or am I looking at a symptom of a much deeper issue?
EDIT: It's now started this problem when i'm running the computer normally. I managed to get through playing The Walking Dead with no trouble on Steam, even got in a few games of Just Cause 2, but the moment I opened VLC media player, the display threw a fit, flashing on and off, black to normal screen over and over and over again, repeatedly making that "bu-dink" noise that indicates you've attached/detached something to the USB or to the computer. Eventually, the screen came back (that's the only reason i'm writing this) but I can't see the taskbar (it's there though, just below the bottom of the screen).
I tried changing resolutions, to no luck, updated drivers again, no luck. Like I ask above, is this just a graphics card issue? Or do I need to worry about my PC as a whole, because, as I said, as far as I can tell, i'm having no issues with booting up, other than the display. Any help would be really appreciated.
