Question Can it be fixed?

Oct 16, 2020
Hi guys, hope everyone is well. As for me, I have few problems with my pc and it would be great if they can be fixed. Firstly, it's slow as heck, and the cooler is really loud. That speed is killing me sometimes. I don't really mind the noise, but it still would be nice to fix that too. But the biggest problem is that sometimes it just goes black. It still works, but the screen is black. I need to put it on sleep and start it again for it to show the screen. And my pc isn't plugged in, and instead runs on battery, this thing happens like every 3 minutes. So is there a way to fix all of this or no? My guess was that something is wrong with the graphics cards, but they are integrated with the motherboard. So should I buy a new motherboard altogether?
