Windows 7: Monitor receives no signal all of the sudden

Since you have 2 video cards, do you have 2 of the correct slots that you could install the 2 cards at the same time ? Then if you have an extra monitor, test both at the same time ?

At least if one monitor is working you could check in Device Mgr to see if the nVidia card is also recognized & possibly update the newest driver on your computer.

Just a crazy shot in the dark idea

There is no blue screen or anything like that. I can hear my computer start up but no signal received by the monitor. Odd.
Nina;

Looking at your specs I would suspect the 650W PSU is inadequate for your quad 4 processor and GTS 250. There will be a sticker on the side that lists the power values for the different voltages, also a google search of the model number will also locate the values. What kind of computer hardware did your friend have to test the card? Faster or slower processor? PSU? Over time a power supply may loose its ability to provide its max power ... especially an under powered one.

This is a link to the Antec Power Supply calculator ... will help size up power requirements based on your setup.

If it is not a power supply issue, then I would suspect this is a motherboard issue. Gigabyte quality seems to have fallen off over the years. I used to like Gigabyte. There would seem to be a conflict between the brand of video card and the brand of RAM and Gigabyte. It is possible that flashing the bios with the most current will provide a fix? Jonathan's link should provide you with the most current file, and you can flash the bios with your test video card that does not seem to conflict with the motherboard.

There is always risk in flashing to a new bios version, although I have never had one fail. Any risk is minimal if you have adequate battery backup (UPS) and do not lose power or interrupt the flashing process. The final step is to reset the bios to "default" values after flashing, then go back and select your preferred settings.

Cheers!

Similar Problem

With my problem, the video card (5670) worked fine for a couple of weeks then blank screen and monitor turns off with a "no signal" message right in the middle of Crysis starting up. Had me stumped as worked fine previously. Re-seated the card - nothing. Pulled the card out and used onboard video which sucked for gaming. Thought I'd try again a few days later and wham - up an running again. 5 days later (today) right in the middle of browsing email and typing doc, same thing. Blank screen with "no signal" message had to force shutdown and take out card to get the onboard video going again. Running the latest Catalyst and system up to date with latest MB BIOS flash a month ago.
Any hints would help.

Sorry I haven't been back earlier - I've only just had a chance to flash the bios (long working week )

Seems that was the solution to my problem

I flashed the bios - restarted - power down and reseated my GTS250 card. Restarted with no dramas and perfect picture.

Thanks to all those that have helped.

I should probably start a new thread but I have now got the message that the windows copy I have isn't genuine and it requires activation. Is this a case of calling them and telling them I have flashed the MB?

HI Nina! Jonathan will be especially happy to hear his idea worked for you, as are we all. Good news!

Yes, if an 'activation' does not fix it, then a call to MS should. Last time I had to make the call it was painless. ha ha!

Cheers!

Nina, rep is not necessary but the thought is worth more than any rep.

I was not aware that a bios update would trigger a 're-activation' but who knows? Hopefully you will have no more activation issues?

Cheers!

Boo :-(

Thought I had resolved the issue but apparently not.

I am thinking I have an 'intermittently' faulty graphics card (a bit like my last one ).

Was working fine for a week or so then the computer would go into sleep/hibernate and monitor would not come back on (I can hear the computer firing up after pressing space bar but no signal to the screen).

Reboot worked the first and second time but not the last time.

I now have another graphics card installed and it has worked fine without failure.

I have pulled the case apart, cleaned all traces of dust and build up from the cover (was thinking a poor circulation issue was causing the case to overheat and shut down card even though MoBo temp has been stable.

So, if it's a faulty MoBo, why is it working with a different card?
Same story if possibly faulty ram (which I doubt, ran Memtest overnight with no errors)
Why a graphics card that works sometimes and why does it only fail after a system sleep?

Frustrating as hell.

Am going to try and reseat the card and see if it works now and update the nVidia drivers (something I SHOULD have done after flashing the bios...d'oh).

Sorry, not really expecting answers, just talking/pondering out loud here

Here is the nVidia download link: Drivers - Download NVIDIA Drivers

A faulty card can act up in any circumstance. If you had said the monitor would not turn on after sleep, I would have suspected drivers, possibly hardware.

Since it's after hibernate, I suspect a bad card is the cause. Supported by the fact that the problem went away when you switched cards.

Ok, so I reseated cards... started up fine. I updated the driver but while having my case open (and the nVidia card in place and working), I have noticed the fan on the card has not started once. All other fans on the CPU/Case are working. It is not usual for a graphics card to not start up at all for 5 minutes straight is it?

I am thinking this may be the cause.

Is there any chance I have put one of the cables in backwards (I have one of those tiny two-pin cables that plugs in but apparently goes either way - sorry, I don't know the name of it). I put it the way that logically looks correct to me but I find it odd that the fan is not running.

Might be another trip back to the supplier.

I really have had my fair share of bad cards in the past 9 months

PS thanks for the driver link always going that extra step Jonathon... one of the many reasons you are a highly valued member here
