So, I recently had the pleasure of being given a graphics card upgrade by a good friend of mine earlier this week. I was happy. I'm not happy right now. Soon after I installed the GPU, I found out I didn't have the right connections on my power supply. This meant I had to either purchase a new "compatible" PSU, or strip wires and make the connection I needed. I chose the cheaper option. It worked fantastically. For about a day. My PC started freezing repeatedly. My PSU was not strong enough to power this new graphics card. The "spend money" option was the only one I had left. So I bought myself a bigger power supply with the right connections. Installed it, everything worked fine, no freezing, great. This evening, my mouse stopped working. I tried it in a different PC, and it was the same story. The thing had completely died. I'm browsing BHW right now, using a "wifi touchpad" app on my phone. I'm going to have to buy a new mouse tomorrow. Either that, or "sulk" in bed and "work" on the laptop. tl;dr: I tried to make my PC better, and now it's worse off because of that. And I'm a moron.
