I have been trying to fix my brothers "old" machine. I'm very new at this so I wanted to get some help from the experts. The problems that I noticed were: 1, The graphics card would get very hot right away causing it to crash by way of the pink screen. 2, The PSU fan made a ton of noise. 3, Every-time I would start a graphic intense game, the computer would crash and restart. So I replaced the graphics card and the PSU fan. But now I have these problems: 1, After about 30 minutes of running I get this burning smell from the PSU fan :/ 2, The new graphics card also gets very hot when I run games. I did get the new PSU for cheap off eBay. Guess I'll have to buy an expensive one.... I got a very good graphics card, so I don't know why that gets so hot. Any ideas? Thank you.
