Hi, i have recently bought a Asus VivoBook s500ca and it is getting really slow and it has 4gb of ram and core i3 so i don't think it should be running as slow as it is so i want to reset it to factory defaults, I have tried loads of ways but it just wont work it say's ''could not find the files needed'' but when i open EaseUS partition master, there is a recovery partiton anybody know the problem ???? i am also having problems with the sound if i have it at 100% the sound will turn it's self of so i have to turn it down to roughly about 80% for it to work again anybody know that problem ????
