PC [Won't show display until rebooted] Help?

[3inksheep]

[FONT=&quot]So I've just built a custom PC, not my first, but I've been having this problem with it that is driving me nuts. When I turn on the computer and monitor, the computer is working, but the monitor doesn't pick up any signal. If I then turn off both the monitor and PC, and retry, it works. Sometimes it takes one reboot, sometimes three or four. [/FONT]

[FONT=&quot]This always occurs after the computer being off overnight. In the morning this occurs every time, however, if I turn the computer on, reboot and use for about an hour, then turn off for say, 30mins, it will turn back on fine, no problems. This only occurs when it's been off for more than a few hours. [/FONT]

[FONT=&quot]I've tried swapping cables HDMI and DVI, three different monitors, checking cable connections, fresh install of windows 10, still, it continues not to work first time. [/FONT]

[FONT=&quot]Any help on this? I really don't know what to try or what could be causing it! [/FONT]

[FONT=&quot]Thanks![/FONT]

Hi and welcome to FPCH,

This isn't really my field of expertise, but I also have an Nvidia GTX 960 installed... running 3 monitors.
It gives me a right headache sometimes....
Only 2 monitors will come on at boot up, I have to unplug the 3rd monitor from the graphics card and plug it back in before the monitor works.
Also on bootup it seems to please it's self which is the main monitor (showing the bios options on boot)
Once it's loaded Windows, the monitor set as primary then takes over and all is fine.
I run a triple boot on this machine and it's the same whether I boot into Win7, Win8.1 or Win10 ... so the problem isn't OS specific.
Problems only occur on boot up.... on a restart everything is fine.
I have seen a lot of people having problems even loading Windows once this graphics card is installed.... especially with Win7.
What the answer is I have no idea... it's just something that I have learnt to live with as I can't find a fix any where.

So all I can say is that I would definitely put it down to the Graphics card.

Maybe someone with more knowledge of graphics cards will be able to come up with an answer for you.

Hmm, that is weird. Perhaps I'll have a tinker with drivers and maybe switching out the GPU to test it. I initially thought it might be PSU issues, but this seems to make more sense if others are also having issues.

Still, if anyone has any advice on this it would be greatly appreciated!

Hi!

I had this problem, however it has a very simple fix. Go into your BIOS on startup and find a setting that says something along the lines of 'default video card'.

Change this to PCI / Dedicated Graphics

Hope this helps
