Can you check bios and see what gpu is selected as primary? Sometimes when I unplugged my card and plugged the monitor in to the mob dvi plug, and booted the machine I got the same thing..beep then no visual on bios. But windows would boot up fine.
Check your monitor signal make sure its on DVI.
Yup it's on the good signal.
Since my USB peripheral doesn't boot, I feel like my power supply could struggle with it? It's kinda new but it may have a defect.
Anyway I can find out if I have a problem with my power supply, without spending 120$ for a new one?
