Question

dvi issue- no video

Mar 28, 2012 10:45PM PDT

hello,
I'm afraid i really don't know much about computers so please humour my humble approach to explaining this problem i have.

I recently bought a computer and I had no problems up untill yesterday when my comp decided to stop sending a signal to the monitor (i've checked monitor on other devices and it works fine).

There are 2 'dvi' connections and a hdmi in the back of my computer. ive tried each of these to no avail.

I can hear my computer boot up but not see anything. (The only difference being the computer fan is louder than usual)

Is there any way i can see whats actually happening?

Any ideas would be warmly welcomed, thanks in advance.

im running win 7 pro 64 on an Intel Z68x-ud5 i7 with a raedon6970 card.

Graphics Card?
Mar 29, 2012 1:47AM PDT

Sounds like the graphics card maybe bad.
Does your computer have a onboard VGA monitor connection? If so you could remove the graphics card and hook up the monitor as VGA and see if that works.
If it does then it's a bad graphics card and needs to be replaced....Sounds like it still should be under warranty.
The higher fan noise could be the fan on the graphics card not a computer fan.

thanks for the reply,

'VGA' is inscribed next to one of the dvi connections, on the back of the machine. So if i remove the graphics card, this connection should instead output a default video signal from the computer and that will identify the graphics card as the problem.

Some quick checking

Open your PC and check to see if there's a video card. One that connected to one of those DVI ports. If present, with power-OFF, remove and reset and assure it fully seated. Reconnect to the one DVI port that was working as before. Now power-ON your PC and check results. Also, note how the fans and such are working and especially the video card if present. If that fan isn't working, it may have seized or failed. Provide the video card is the problem, remove and replace with another one or use whatever warranty you have. Alas, you may want to remove the video card entirely and use the "on-board video port" if present. More than likely a VGA type, you may need a DVD-VGA convertor in order for its use, should you care to go that route. Chekl all that and report back with results.

To figure this out.

I try the monitor on another PC and
I try other monitors on this PC.

Did you do that?

i opened the computer, removed the graphics card and reinserted, rebooted and it works. It didn't seem loose but i wondered if it had become slightly dislodged in transit.

noise has disappeared too.

for future reference- i didn't see a vga connection inside but i didn't look too closely. is it fairly standard for there to be an 'onboard' video connection in the comp regardless of the presence of a graphics card

thanks again for all your help.

Specs info
Mar 30, 2012 4:42AM PDT

It all depends. You gave this info and it lacks that detail, we just don't know until checked for this or that.

"im running win 7 pro 64 on an Intel Z68x-ud5 i7 with a raedon6970 card"

Using the above provides for the info needed if your mtrbd. has "on-board video port". Once you review the "specs" you have the true h/w provided and/or supported. If what you provided is correct, the mtrbd. specs are at the below link:

http://www.gigabyte.com/products/product-page.aspx?pid=3848#sp

connectors-----> http://www.gigabyte.com/fileupload/product/2/3848/4595_big.jpg

It appears no video port is present from the mtrbd, itself.

FYI-The new wildcard if you will are the presence of HDMI connections on some newer mtrbds. which in turn replace VGA ports, yet do have video from the mtrbd. as also the newer cpus have "graphics/GPU" build-in which is accessible by the mtrbd. design(chipset) and bios setting. Yeah, it gets confusing. That is why you need to inform yourself of what your PC is capable of by visiting the support website or check the provided discs for a manual of PC.
