I have such device as Lenovo G510, which has i7-4700MQ with Intel HD 4600 and Radeon HD 8750M, screen resolution is 1366*768.
Couple months ago i reinstalled windows. I haven't been noticing this problem because i didn't play anything heavier than Factorio.
But today i decided to try playing...
Some lore:
Some months ago i noticed that my games were lagging much more than usually. Yesterday i decided to play a game, that i haven't been playing for 2 months. For some reason, instead of 40fps on high presets, i got less than 20fps on minimals and it was dropping down even more(3-5fps)...
I tried to boot computer without RAM, then without video card, after that without HDD. I didn't hear any beeps from computer. PSU is ok , tried to use another PSU, nothing changed.
I decided to add some ram to my old pc, because 2x1gb wasn't really enough. So i replaced one of the 1gb ram stick with 2gb ram stick. And here the problems begin: first of all i saw on screen something about "BIOS recovery", also it printed a lot of dots. I decided to turn it off, so i held off...
Hyper 212 is just perfect, i don't know really much about all that liquid cooling stuff and don't want to risk too. Btw thank you a lot Ryan, you really helped me out with these computer parts. Also thanks to others, who helped me too.
