I have a 2-year old ASUS laptop with Windows 7 and Intel Core i7. I have not had major problems with it until a month or two ago when my laptop started freezing randomly. The cursor freezes, the keyboard becomes unresponsive, and everything just freezes. It freezes whether I'm online or offline. I have to do a hard reset to get it running again. Usually it still freezes once a day or once every two days. But lately it's getting worst. My laptop freezes every 15 minutes or so. Sometimes when I restart my laptop and the Windows recovery screen appears where it can boot in Safe Mode, it freezes at that point too. And sometimes it won't even start back up. It'll power up for a few seconds and then shut down on its own. I have used avast!, Malwarebytes, SuperAntiSpyware, and tdsskiller to scan for problems every time it freezes, but there are no infections. I've also used CCleaner. I also have Adblock and SpywareBlaster installed.
I can't figure out if I have virus/malware or some other issue like overheating, or video card problems (I remember not too long ago my display driver crashed and gave me the message "Display driver stopped responding and has recovered"), or insufficient RAM.
In desperate need of help! Thank you.
