Question Monitor sometimes not getting signal

[Alex167691]

Hello,
I recently build a Pc and when I start it, the monitor won't recive any signal unless I restart the Pc a few times, take the rams out and put them back in, take the power for like 5 min. and so on...
After the monitor gets signal I have no problem with the Pc. But after I shut it down and want to start the Pc the next day, I have to go through the whole process again and again....
Pls help, I have no idea what could cause the problem because the PC just works fine...
Thanks in advance!

The 6750 XT is recommended by AMD to have a PSU of at least 650W. I am not saying that is for sure your problem, but it sure could be.

you use the 2 pci-e cables but this seams as suggested psu could not handle all power for system and gpu try to borrow a more powerfull psu for test .

So you guys mean I should get a more powerful supply?

Just got a new power supply and the problem still persists...I guess the only option left is the graphics card...
