Hello, I have a Vizio laptop, I just got it back from the repair shop, they had to reflow the motherboard, and when I got it back I turned it on and it took about 5-10 minutes to boot up, which is weird because it usually boots up in about a minute. And when I log on, it freezes constantly, I click one thing and it stops and freezes completely. I'm at a loss and I've tried to do many things, one being a system restore point to back a month ago, but it didn't work.
The specs on my laptop are ont his Amazon listing:
My computer is supposed to work super fast but it's just a disaster now, please help me.
