Seemingly out of no where, (yesterday it worked fine), my desktop won't startup at all, I click the power button, and the fans start, but nothing at all shows up on the monitor, upon several upon several attempts, it seems that maybe 1/25-ish times the computer will actually boot-up properly, and thats only if i unplug absolutely everything but the power cord and HDMI cable. Im not really sure what info I should/need to provide.
