Question CPU won't give image

[_|)arzival]

I boot my computer with the monitor connected to the CPU (no external graphic card) and nothing happens. My monitor keeps turning on and off and no matter how long it takes, the CPU won't give an image

Is this a brand new build?

Work your way through this list in its ENTIRETY, even if you've tried a step already - https://forums.tomshardware.com/thr...ng-about-post-boot-no-video-problems.1285536/

Initial suspicion is your generic PSU is not up to the task.

3 months old, it was working, but my graphic card is done for, so I went to try and boot the computer only with the CPU and it didn't work

Reset the CMOS by pulling the coin battery on the motherboard for 30 sec and replacing.
