ATI 6950 display problem.

post #1 of 12
Thread Starter 
Hey guys, I'm really at a loss here. My computer has worked fine for a good while, minus a few kinks, but that's from me fiddling with the GPU and CPU settings. Anyway, back on topic.

Well, it seems my computer refuses to display a signal out of my Gigabyte ATI Radeon 6850. Everything boots up, and I can see the fans running on my card, but it won't detect my card, and all I get is "No VGA/DVI Signal!". I've looked around on Google, and tried different things, but nothing works. I tried different monitors with different cables, and the same deal: No go. I use a vga cable (I know, I'm a noob, but my monitor is only vga. ) via a dvi-vga adapter. Any ideas what it could be? I am running out of ideas. >.>

Edit: Whoops I mean ATI 6850. Bad title.

The first thing I would do is make sure all your physical connections are proper. all the cables hooked up properly. Card is nice and good in the slot, power connected to it, VGA-DVI adapter is snug and your VGA cable is snug on it. Does not hurt to double check all these. Also make sure your card is in the same PICe slot as it was when it was working.
Then see if there is a place in your motherboard that gives you a post code or if there is an audible post beep.
If the above two are checked and fine, then there is probably a BIOS setting messed up.

Both check out. Probably is a BIOS mishap. >.>

I don't suppose you've changed the PCIe frequency? because that would most definitly happen due to that. First route of action id take, would be to reset your cmos/jumper (take out the battery for ~5 mins and put it back in) and then reconfig your bios, id say that'l sort it , if its not a hardware problems.

bios set to PCIe graphic,not onboard,or onboard disabled?Plug your monitor into the onboard vga connector and verify that works.

Hmm, interesting, I will give that a shot.

I've always had it set to run off of my graphics card first. I learn from that mistake on the first day I built my computer.

That doesn't mean it didn't get switched by clearing cmos
Make sure your monitor and cables,drivers etc. are working by plugging your monitor into the onboard GPU.That way if it is a driver problem you can fix it,or know for sure it is a GPU problem

Yeah, my onboard GPU works, so I am guessing it could be a driver problem (More like hoping). I will re-download the latest driver and see how that works.

Edit: Yep, I loaded my computer up on my onboard, and oh what message do I have here? Says either no driver is installed, or it's corrupt. Looks to me to be a driver problem (still hoping it's just that.).

Interesting....I would have thought that even without drivers your card would have displayed stuff - albeit in garbage font. I do not have on-board graphics on my card. How did you install drivers in the first place?

Using the crappy onboard, I just install the latest driver, then reboot my system and then use my graphics card?

Edit: Wasn't drivers... Damn I was hoping it be that. >.>
