So. I recently got a laptop (used one) from my dad. It has a ATI Mobility Radeon HD 5650 graphics card, 4gb's of RAM, Intel core i3 processor and a 500 gb harddrive. When I just got the computer it was running League of Legends on max graphics around 70-90 fps and lowest around 130-150 fps. My computer got really hot when I played so I decided that I should buy a cooling pad. One day before I was going to buy the cooling pad I played some Path of Exile. I played like 2-3 hours and eventually it crashed. Not blue screen or anything just like turned off instantly. The next day I bought a cooling pad and decided to play some League of Legends. When I started the game I realized my fps were about 20-40 on max settings and 30-55 on lowest. The same happened to my cousins laptop. It crashed because of overheating (we think) and League of Legends now runs very slow. Our computers are almost equally powerful. It's not alot of difference. We havent tried many other games but we would like to know what has happened and how we can fix this. Thanks for reading!
