I cleaned out some dust in my fans just to keep my computer cleaner and also unplugged all the cables just to do some better management. For some reason now when I press the power button the fans run fast like the system is turning on, but nothing shows up on my monitor and the two times it did there was little glitch parts that weren't coloured right. I also just put in a new hardrive. I don't know why its not actually doing anything and I'm getting really frustrated with this, can anybody help me or do you even understand what I'm asking?
