You may not actually have a problem with your computer. If you are using a dial-up Internet connection, it may be with your Internet Service Provider. There are certain times of the day when I experience exactly the problem you describe, and know the frustration that it can cause. My ISP (Internet Service Provider) is over-subscribed for the local hub that serves my telephone exchange so at any time when there are large numbers of people trying to access the net - - my web access gets "flaky" and causes the problem that you describe. With my local ISP, I find that the least traffic is usually after 11:00 p.m.
If you are running Windows 98, Windows ME, Windows XP or similar, you might want to try clearing out the temporary files by going to :
1.) Click on Start
A.) Select Programs
B.) Select Accessories folder
C.) Select System Tools folder
D.) Click on "Disk Cleanup" icon
The program will now check your machine, and will shortly display a dialogue box asking if you want to clean drive C. Click OK and the examination will continue - - a few seconds or a few minutes later (will depend upon the speed of your CPU and the size of the hard drive) you will receive a status break down that tells you how many temporary files are saved on your machine. You need to be most concerned with "Temporary Internet Files" and "Temporary Files" - - when I perform this operation on my machine, I choose these two options at the bare minimum - - when you click OK, these temporary files will be removed. This is not a guaranteed solution, but it is a good first start.
I find that with my setup, the two issues described above are the most likely causes of strange and otherwise unexplainable hiccups with my web browser.
