The first thing you should see is a bios splash screen.
The bios does not use windows drivers.
If your cpu has an igp try connecting to the mobo.
Try a different cable.
I recently built a budget gaming PC and have had it working with no problems up Till now, i had to change from a tv with 1920 x 1080 resolution to one that only supported up to 1360 x 768, so i adjusted my nvidia display to that with no problems, the problems started when i wanted to go back to muy previous 1920 x 1080 tv because i don't have the other one anymore, first of all it wouldn't detect my PC's signal (i supposed it was due to the display change)so i tried with another tv And that one did detect it so i set the resolution back to 1080p shutdown and tried with my Main TV again. It didn't work and after that none of my tvs would detect my PC so after many hard shutdowns i am currently stuck with no display and i'm not Even sure If it's sending signal anymore since the PC now shuts off with one power button press instead of holding the button(it may be because i tried taking off the ram And placing ir again) any idea what i can do?
