whenever I try to turn the computer on, the motherboard light lights up, but the monitor shows zero activity, it doesn't even show the bios screen, or the startup commands for the bios. I checked the inside of the computer, it seem's that it's all connected properly, but it still just doesn't show anything on the monitor, I tried it out with a different monitor, and I achieved the same result. So I've deducted that this is a computer issue, but I am unsure of what it could be. the HDMI cabled I am using is plugged in properly. I could use some help. Thank you

The HDMI cable may be plugged in properly but is it plugged into the motherboard HDMI port or on the GPU?

Yeah they do, I'm guessing the problem has to do with my GPU or something like that

Just did, nothing new happened. still blank screen and nothing showed up. So I guess it's not a problem with the GPU

So I just fixed the issue, apparently, the 26 pin power connector got loose and me checking that cable just wasn't a thought I had at the moment. Thanks for your help though!
