When you say you can hear sound, do you mean you can hear the sound through monitor speakers, or the monitor is making a sound (like a buzzing noise) or is the noise from external speakers / headphones? Have you checked to make sure all the cables are connected properly (check the Power Cables especially, mine have a habit of loosening themselves - I think it's the gremlins). What are your PC specs? Is the PSU supplying enough power? What monitor is it as well? How old is it? Check with the manufacture for terms of RMA'ing it if we can't help solve the problem on here.

Have you checked power saving options
the simple things are easy to miss.

Are you running in a supported resolution by your monitor?

tig1954 · 31 Dec 2009 at 17:05

tig1954 · 31 Dec 2009 at 17:07

Have you updated graphics drivers and o/s updates for win7?

Do you have this issue with any other games?

tig1954 · 31 Dec 2009 at 17:13

i have updated drivers not got round to putting on any other games yet seems pointless i reenstalled win 7 twice i also have this problem during install when it says restarting i have to shut it down to reboot then it carrys on installing

tig1954 · 31 Dec 2009 at 17:17

might it be my graphic card failing

mattyfez · 31 Dec 2009 at 17:21

hmm, are you sure all cables are secure, internal and external? PCI cards, rams etc. all properly seated?

Might be long winded but you could put your old OS back on to see if the problem remains...

If you can get hold of any compatable graphics card to test, that would also rule out/confirm a problem.

thank for help will check all cabels it has to be something simple

Jason1973 · 1 Jan 2010 at 11:48

down load and run furmark, to check for the gfx card stability.

Does it cut out in normal desktop, (apart from power saving options)?

Jason1973 · 1 Jan 2010 at 16:26

Run again and see what happens.

Ouch your problem is with the card overheating.

Check the fan is spining up to speed.

At least I think the driver problem is sorted.

What GFX card do you have?
