If I have any flash object in a browser for more than about 30-45 minutes my processor use jumps from about 30% on both cores to 100%. Even I close Firefox, Chrome, IE, or the Hulu desktop app when they start getting choppy or laggy the processor still maxes out. It is consistent across all sources of flash media, www.hulu.com, www.armorgames.com, www.youtube.com, as well as flash based ad banners. Even if I am viewing short clips after about an hour of total playing this issue occurs. As a stop gap, I installed Flashblock in Firefox (my primary browser) to avoid flash ad banners from crashing may machine.
I would restart my machine but when it came back it was still laggy and the cpu was bouncing around 45% (+/- 15% every second). Originally I had Microsoft Security Essentials installed but when the machine would reboot it would crash and after login the alert window would slowly (1-2 frames per second) rise from the taskbar notify stating that it wasn't running. I originally thought that Security Essentials was being a little paranoid and somehow deep inspecting Flash, and then when I restarted interrupted it somehow. So I un-installed Security Essentials and installed McAfee and am still having the problem.
Another another few wrinkles are, when I try and restart I get the warning that If I do I will interrupt a background process. But there are no processes listed. Also when I open a resource monitoring tool like task manager or Resource Monitor, the monitoring tool is reported to be consuming anywhere from 35 to 50+% CPU.
Also. When I have closed out of a browser after this lag starts occurring, I also close out of any other applications using the network. Instead of the network dropping to it's idle or rarely used state, it starts spiking at about 1 to 5 kbit every second or so. It seems to be rhythmic, also it seems to correspond with spiking cpu usage. After I boot and before I have opened a browser for the first time I do not see this spiking of the network or cpu.
I am running on a:
- Dell Latitude E6400
- Intel Core 2 Duo T9550, 2X 2.66Ghz
- 4 Gb ram
- Win 7 Professional x64
- Flash Player 10.0.32.18
- McAfee VirusScan Enterprise + AntiSpyware Enterprise 8.7.0i
This is a fairly clean install only about a month old. I have gone through and cleaned out pretty much all the run on boot processes and unnecessary services.
