This is a problem I've started having recently. About a month ago maybe. When I start up my computer, it's fine. No hang, good response time. Then, maybe 30-45 minutes later, it begins to hang. By hang I mean, taking 30 seconds to launch an application after hitting "run as admin". Then I get stuck at the grayed-screen right for another 30 seconds before the admin access pops up. Also, any program I try to open (paint, for example) will take up to a minute to open. Sometimes longer, depending on the exe. Firefox (thought originally the problem was chrome so I switched) will also freeze. I get non-responsive errors often, but they go away in about 30 seconds. Browsing similar threads here, I've noticed a few ideas as to what it could be. It is not my CPU being overloaded. This occurs while doing simple web browsing. Rainmeter tells me my CPU is never going over 50% while browsing. Or even close. It is not my RAM. I have 8gigs, and it's also telling me I'm not using over 3. Even when gaming. It is not my fans. I don't hear them get louder before a freeze. I've updated my video drivers, windows, flash player, adobe, and even my sound drivers. They're not hanging, best that I can tell. I'm on a ASUS G74Sx laptop. Bought it just about 1.5 years ago. 8gigs of RAM. GPU: GTX 560m. CPU: Intel i7-2630, 200G.hz As a warning, I am not THAT tech savvy. Dumbing everything down to layman's would be appreciated. Thanks in advance.
