2X Kingmax 4GB, DDR3, 1333MH
Nvidia GeForce GTX 560Ti
Just got a new motherboard I installed windows again.Then after I installed nvidia driver and restarted it,after windows loads I get no signal to monitor.Then I've tried with my old 8600 GT i installed its driver and the same thing happens.I've tried with windows 7 32 bits and 64 bits,different driver versions,with only one piece of ram at the time but it didn't help.Both video cards work well on other pc.I can't figure out what's the problem.Is it possible to be something wrong with the motherboard?
Can't find anything like that in bios, I don't have onboard graphics.I've tried with a Radeon HD 6850 and it doesn't give signal to monitor at all,coolers from GPU don't work even though it's properly powered, it's like the motherboard doesn't recognise it.
I'm sorry I don't know what do you mean with discrete GPU.As I said with GTX 560 TI and 8600GT after windows loads the monitor goes black it has no signal only after I install the driver.But with the HD 6850 I don't have signal at all to monitor.
Discrete is a separate graphics card, as opposed to the graphics processor in your CPU. I didn't notice before, though, that you have P67, so you can't use your integrated graphics anyway.
Do you have any way, right now, to access the settings of the computer?
