No Signal after switching video to PCIEx16 on BIOS.

Gigabyte / G31m-es2l

Specs: Windows 7 Ultimate, 3.2 GHz / 4094 MB
I had an issue getting my friend's computer to display video on his dual monitors. It had been working well with dual monitors before but then it started having problems with performance, or drivers, freezing on boot, and even overheating.
I took a look at some of the problems and managed to get it to boot and display on a different monitor without the video-card.
Things appearing to be back in order the video-card was put back in place to set up the dual monitor visual. However the displays would show no signal on the monitors and would only display when the VGA was connected directly on the the motherboard.
So, I changed the settings on the BIOS to use the PCIEx16 for video, and now get no signal on either the (VGA) onboard graphics nor the (DVI) Video Card.
I tried resetting the BIOS finding CMOS and also tryed removing the battery and still nothing. It still shows no signal on both the intergrated and video-card graphics.
I use a DVI to VGA adapter for the video-card.

I am not entirely on point with the specs and for now won't be able to provide the exact names and or manufacturer brands for this Desktop PC hardware.

Culer fins ala mort!

To determinethe specs of the computer...

Download Belarc Advisor and run it fromwithinwindows. It will generate a report covering everything about the computer; including software keys, hardware details etc.. The report canbe saved as a file, and also printed - which if possible do.

Also if you run the built-in MS utility ms32info it will produce similar.

To run msinfo32 go to start - run and type msinfo32, and then press enter/return

If you know the make of the add-in card post it here; may enable pholks here to find the manual for it. It is just possible that you have set an option on the cards control panel or similar - which may be accessed via right click on the desktop display...

Guessing a little but you may need to re-install the drivers again.

"and even overheating"

If it's overheating best first check that the vents are clear. If you are happy inside clear the dust from fans and the CPU heatsink. If the video card has a heatsink clean that too.

This is the first step before worrying about software.

Always pop back and let us know the outcome - thanks

I edited and added to my previous post.

trvlr- I believe its an ATI video card but I don't know the model. I get no signal through the through the onboard graphics as well. I don't know if its a drivers issue.

I also forgot to mention I don't have the computer. So I won't be able to post the full specs.

Derek- It had been overheating and wouldn't boot. I cleaned it and added artic silver to the CPU.

Without the add-in card does it give a display or not; i.e. using the on-board graphic chip/adapter?

If you can get someone to run either of the utilities suggested above, and then send you a copy of the report (a file ideally, or even hard copy - email?) you could then post details here?

What we're after is the add-in card details, which those utilities will reveal.

ATI cards do have their own ""control panel" as it were which is accessed via the desktop - right click to open the dialogue window for all things to do with display... But this presumes of course that can see something on a screen with card installed.

Incidentally have you tried booting the system into safe-mode? If so you can uninstall the ATI card (add/remove hardware); then reboot to normal mode. If you can then see a default vga display, then you can try re-installing the drivers for the card. But be sure to use the correct set.... Which is why useful to know the actual card make/model. Although windows can sometimes search for suitable drivers if you opt to let it, should you not have drivers to hand. Seem to recall that is an option in the ad/remove hardware routine (add in this case obviously).

Did you apply using the correct method:
Did you clean off all old thermal compound?
Clearing CMOS requires unplugging the power cord and shorting across the clear CMOS terminals briefly OR unplugging, removing the battery, waiting a minute or two while tapping the power button. The first method is preferred.
After clearing the CMOS memory, plug the monitor into the motherboard's VGA or DVI connector, enter BIOS set up and reset to optimum settings (like default but better), Save and Exit, restart into BIOS set up and manually set basic parameters (time, date, CPU, RAM, etc., Save and Exit.

You have to be a little bit crazy to keep you from going insane.
