I have some suggestions to install Gamebooster(IObit product) to increase pc performance while playing games and you know,i am facing some problems while playing games,pc freeze or blue screen of death.It’s an iobit product that’s why i am so cautious,shall i give it a try or it will damage my computer?
Wouldn’t bother with game booster, your speed problem is probably related to only having 1 gig of ram, it’s very cheap to add extra ram nowday’s, an extra 2 gig would do wonder’s if your system will take it ? if not you should at least be able to add an extra 1 gig, and have a look at what you have running at startup to see if there is anything not needed as everything that is running is consuming memory.
Added to that I’m sure you know the feelings of many about the ethical/moral standards of Iobit. With so many free products about without any doubt about the companies ethics, I wouldn’t be going there for any product.
I use IoBit Game Booster 2.2 and I didn,t see any problems with them.
Lep pozdrav 
Its a ethical/moral issue with iobit because there thieve’s and if you believe in ethic’s and moral’s then you dont use there product’s.
No IOBit software for me:
