Greetings. My laptop has been freezing 3-5 mins after i log in to windows, it usually happens after i logged on the online games like dota2 and dragon nest sea. When it freezes i couldn't do anything, things like ctrl + alt + dlt don't work. the only thing i can do is to manually restart my laptop by pressing and holding on to the power button. when I'm lucky i just have to manually restart my laptop once and it will be working fine, but sometimes i have to repeat the restarting process 3-4 times and 3-5mins later it freezes, I've tried system restore a couple of times, but its doesn't seem to do anything to help.
any kind of advice or help will be appreciated, sorry for my bad english...
