Question Pc broke, what is wrong? (Fixed)

[Alecadoo]

So a couple days ago my mouse broke and since I had no spares my pc was turned off for like four days (plug socket off as well) when I got a new mouse and tried to turn it on again my monitor detected the hdmi signal but only showed a black screen with a small white rectangle towards the upper left of the screen, I also tried an old projecter (also hdmi) to confirm that the problem is not my monitor. I would assume that this problem is my graphics card but I wanted to check if there was anyone who has had this problem and knows for sure.

I would replace the CMOS battery and try it again.

I will buy one and try that, thanks

Other than the lack of a signal, did it appear your PC booted?

all the fans were spinning and all the lights were on, but the power button wouldn't work (although the reset button would)

I don't know what the problem was but it now works, It may have been a bad connection with the CMOS battery because I did move the battery in its socket to read the text on it and that could have fixed it but I honestly don't know. Thanks you guys for trying to help anyway.

I would still replace the battery.
