I've been having this problem for nearly a year now and I nor any of my computer friends know what could be causing it.
My system hangs up every 10-20 minutes for about 2-3 minutes ONLY IF a web browser is open.
It doesn't have to be active. I don't have to be browsing. I could have it open, minimized and let it sit and eventually I can see the activity light come on on my tower while my hard drive and/or CPU seem to be going insane. The whole system is bogged down and it will get to the point I can't even click on anything and everything just hangs up. After a few minutes, it immediately stops and everything resumes as normal.
Nothing else causes this. I can be playing a new video game, rendering video, talking on Skype, all of that at once, etc, for hours on end and my system is fine. But if I have 1 tab on a browser open, the whole system will hang up as described above. It doesn't even matter which web browser. I've used Chrome regularly for years now, but out of my multiple attempts to try to resolve the issue, I've also tried using Internet Explorer (lol), Firefox and Opera. Doesn't matter which I use, same effect. And again, only web browsers do this. If I have a browser open and try to do something else, like playing a video game for example, it'll freeze the game while it's doing whatever it's doing for a few minutes. I just sit there and take deep breaths and try not to throw it out of the window. lol
I've tried several things over the past months. Selective startup (disabling all unnecessary processes when booting the computer), safe mode, virus scans, switching anti-viruses (from Avast to MSE), boot-time virus scans, using Advanced System Care, using CCleaner, Malwarebyte's Anti-Malware, uninstalling and reinstalling Flash, disabling Chrome's built-in Flash, disabling hardware acceleration, disabling/enabling Flash protected mode, updating all drivers, fresh driver installs and probably several other things I just can't think of off the top of my head. It's also not a heating issue. Event viewer doesn't show anything.
One weird thing did happen recently that might be a clue to something: I was watching a video on YouTube. It was fairly lengthy and I wasn't doing anything else. Naturally, the system hung up even though it was just sitting there and froze the video to where the wheel came up like it was buffering or what have you. I noticed the activity light stopped but the video was still frozen and my CPU was still going nuts according to Task Manager. When I refreshed the page, the video started playing normally and the CPU immediately went back to functioning normally.
I know all of that is a lot of info and, in all honesty, I would just reformat the drive if I could. But my secondary 2TB HDD kicked the bucket last year and I have nothing to back up all of my data on to at the moment in order to do so, and I can't just afford to go buy a new one at the moment. So I'm stuck still searching for what I could possibly do to fix this. It's literally the only issue my computer has and I'm getting more gray hairs because of it.
I'm running Windows 7 Ultimate 64-bit. I have an Intel Core i5 quad-core CPU running at 2.67GHz (first gen), 8 GB RAM, Radeon HD 7950 GPU. If any more info is needed just ask.
Thanks in advanced for reading and any ideas anyone has. My computer hung up twice just while typing this...
