Monitor saying "No Signal" randomly

November 18, 2012 6:12:37 PM

Hi all,

So I just installed a new GPU (AMD HD7850) and a new motherboard (ASRock H77 Pro4/MVP). They work fine but oftentimes my monitor blanks off by itself and saying "No Signal". This happens most frequently when I boot the PC (most of the time I can't see the BIOS Screen and the monitor only starts to show the display when the Windows Login Screen is up). I believe it's not my monitor's problem as I tried connecting it to my other PC and it works perfectly fine.

This wouldn't be a problem for me as I don't really pay attention to BIOS screen. However, recently it happens in the middle of Windows (I was browsing the internet and it suddenly blanks off and shows the "No Signal" again). After rebooting it works fine again.

This problem is rather random and sporadic. Can anyone help me? Thanks!
