Hello there

I need help please since upgrading to windows 7 while playing certain games at random we get no signal showing up on the monitor but you can still here the sound the only option we have to restart the computer by holding the power button in for 10 seconds.

The Art of Murder 3 we get the problem sometimes when going to options to save or pushing escape key. Same thing happens with Some CSI games Dark Motives on level select menu we sometimes we the no signal error.
We have a Nvidia geforce 8600 gt.

Thanks

Make sure your Nvidea card is set to 60 mhz.
Go into your nvidea display and set it to 60hz.

Thanks

I changed it in Monitor settings screen refresh rate to 60 Hertz it was on 59 before Is that right please?

Thanks

Sounds right. See what happens and let us know. I assume you double checked your cable connections too.

Hi there

The problem i am having is when we set the screen refresh rate to 60 it will not stay on it it keeps defaulting back to 59. Do not know how to fix this.

thanks

Is there an option after you change it to 60 to apply the change ? Or are you just hitting ok ?
There will probably be a game tech here soon who can help you more than I. Have you updated your video card drivers lately ?

It's possible that the monitor itself is the culprit -

Screen refresh rate in Windows 7 does no...atible timings)

Depending on the OEM you may be able run something like Riva Tuner or ATI Tools. I don't use them much anymore, but they should be able to lock the refresh rate for you. Both are fairly advanced tools - mainly for over-clocking, so if you want something that's a bit easier to use try NV Refresh Tool - NVRefreshTool 2.1a

You can locate the others on the Guru of 3D web site.

And the "no signal" leads me to think the culprit is the monitor also... As I said earlier, have you checked your cable connections? Maybe even try a different cable...

Is this a laptop?
I've heard of this problem more with laptops than with computers with separate monitors.

Hi there

I finally got it fixed I have not had the problem for a few days. Until I started to play the game called Bully Scholarship Edition. But has only happened 2 times in about 5 days.

I spoke to a computer tech guy near where I live here in Australia he had other customers with the same problem but he has no idea how to fix it. He also told me that ATI Radeon cards where doing it also not just Nvidia.

Thanks

Glad to hear you have it under control (most of the time anyway).

Do take a look at the utilities I linked to above - they were created just to handle situations like the one you're experiencing.
