I've been having a lot of problems with my desktop recently. It all started when i got a new graphics card. For a few weeks the screen would sometimes be kind of wavy for a few minutes and go away. A week ago it started shutting itself down and i would have to use boot repair to get it running. This past friday it simply wouldn't launch fully. It would say getting windows files then shut itself down. I figured the problem was the power supply so i bought a 1000 watt one to replace my 450 watt. It fixed the problem but now there is no display, no matter where i plug my monitor into, neither the graphics card nor the integrated chipset works. I figured the motherboard must have gotten fried because my mouse and keyboard wouldn't turn on but if i were to plug in something else like my ethernet cable it would show that it is connected. I am at a loss as to what i need to do. Also if i try plugging in my keyboard or mouse into my laptop i get an instant bsod.
