stall during web page browsing

For the last few months or so, my PC stalls during browsing a web page. In particular the E-bay web pages.
It will be fine for 5-7 minutes and then the page becomes unresponsive and the loading circle keeps on turning.
Occasionally the loading of my Windows Essentials 2011 takes a long time to load compared to the regular start-up.
At times I can use the taskmaster to end the process, but other times I can only use the Ctrl>Alt>delete to get back to the web page.
Again, it will be fine for a few minutes and the same thing happens.
I have done the sfc/scannow, the MBam scan, the S&D spybot scan, the adwcleaner, Ccleaner and the Zone Alarm Extreme scan. None turned up any nasties.
It is not a huge problem, but I am worried it may be an indication of a bigger pending problem.
This PC is about seven years old.

Hi TZ, I haven't tried it in another browser, but will right away. Presently I use IE 11

Thanks, Il'try that. I just tried it in google chrome for about seven minutes and had no problem so far. I shall report back if it does't happen again in IE 10.

Thanks again, I reverted back to IE 10 and the stalling problem has not occured again.
