Firstly, I know many people have this problem, but none of them seem to be the same situation as me. I just installed a new graphics card, and a new power supply. Once I had everything connected, I booted up windows fine. I than rebooted, activating a program called softXpand. I want to remove this program, but that's aside the point. The real problem is whenever I try to boot up my computer now, it will show the windows icon and right when it plays the startup sound, my screen goes blank. I double and tripple checked all the cables, and did not open my computer up between the first and broken startups. Also, when I try to boot in safe mode, it stops loading at CLASSPNP.sys.
I think this may be an issue with drivers but am far from 100%, does anyone know why this is happening, and maby how to fix it? Thanks in advance.
