It isn't a new laptop, it's a 3 months old laptop.
Let's keep it simple: it's either a hardware issue or a software issue. To find out which of the two, you do a system recovery back to factory conditions. The exact procedure is dependent on the manufacturer, so you might have to look in the user manual how to do that. But most likely it means just booting from the recovery disks you made or from the recovery partition. This will make your laptop really new, like it was when you bought it.
Be sure you have a backup of everything you don't want to lose!
If it's OK now, you're done. But you should take some care to not install as many bad softwares as you apparently did 2 months ago.
I bought a new Asus laptop about 3 months ago, and I have been having issues with it for about 2 months.
The problems I am encountering are random freezes in programs, programs and folders not responding, the computers sound randomly shutting off, Windows errors when shutting off and updating, sound popping and crackling and freezing for a few seconds, slow response when right clicking folders and files.
What could this be?
Its a Windows 8 computer.
