It would appear that your browser is perhaps timing out.
One computer works fine, the other has this apparent “time out” problem loading web pages. It would seem to make sense there is something uniquely different between the two computers obviously and it does not appear to be related to the actual browser (you’re saying both Chrome and IE have the issue on one computer) so perhaps it’s the OS.
Have you recently upgraded this computer that has the problem to WIN8?
Does your other computer that does not have this problem use another OS than WIN8 (perhaps WIN7, if so see 2nd link below)
However before we leave just looking into issues with Chrome: I’ve done a little research for you on this and apparently a lot of users are having problems with Chrome not loading pages completely at which time they need to be refreshed.
Read through this LINK: https://productforums.google.com/forum/#!topic/chrome/8-RXiHZq5d0[1-25] (the script is a bit sketchy on this page so just press “continue” if you get a script error message)
You’ll notice that the OP says in part quote: “It half loads webpages about 50% of the time.” and you’ll see there are a lot of posters in this forum saying the same thing.
In this link when you take a look at the detailed answer you’ll see (where support says “Hey folks”) in part quote" “Some with a Samsung device, have pointed out that (a) uninstalling the ‘Support Center’ from their device, followed by (b) clearing cache and browsing history from ‘the beginning of time’ resolved the issue.” (you’ve tried most of that perhaps not “browsing history” and perhaps not from “the beginning of time” however. There is a lot of input on this issue and a lot of followup to check out.
Also the tech input stated the following at point #4: Some of you have already tried these, but if you have not please try it and let us know if it helps:
(a) Does the issue continue to occur when you switch to an Incognito window (Ctrl+Shift+N)? If it doesn't, check (b) and (c) below.
(b) Try clearing cache and browsing history (Ctrl+Shift+Del) from "the beginning of time". Did it help?
(c) Try disabling all your extensions. Did it help? If it did, now try enabling your extensions one at a time to identify the one that may be causing the issue. Please tell us the Extension ID (this will be visible once you check the "Developer mode" checkbox at the top right of the chrome://extensions).
(d) Create a new Chrome user. In this new browser window, does the issue still occur?
OK, moving along to look further regarding network issues (which is more likely where the problem is perhaps).
Here is forum on this topic about “browser page time out” issues in general - TOPIC: Page time out in browser
The post by Broni HAS SOME VERY GOOD IDEAS TO TRY QUOTE:
Let’s go through some basic steps…
Turn off computer. Disconnect router, and modem from power source for 30 seconds.
Power them back on.
Restart computer.
If that doesn’t work, bypass router, and connect computer straight to the modem.
If that doesn’t work…
Go Start>Run (Start search in Vista), type in:
cmd
Click OK.
In Command Prompt window, type in following commands, and hit Enter after each one:
ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
Restart computer.
If that doesn’t work…
Go Start>Run (Start search in Vista), type in:
cmd
Click OK.
At Command Prompt, type in:
netsh int ip reset reset.log
Hit Enter.
Type in:
netsh winsock reset catalog
Hit Enter.
Restart computer.
If that doesn’t work…
Download, install, and run WinSockFix: http://www.softpedia.com/get/Tweak/Network-Tweak/WinSockFix.shtml
Restart computer, and check again.
I would try some of these things to see if this helps.
Now let’s discuss the OS, which seems more likely than just a browser issue obviously (especially if your two computers are using different OS’s).
Here’s more on WIN8 as far as problems related to your issue using this OS:
From the Microsoft Community - Question: Browser connection problems following Windows 8 Upgrade There is a lot of detailed help on this web page.
Here is another interesting FORUM link on Windows 8 speed issue: Windows 8 Slow Web Browsing on Chrome, Firefox, IE? Win 7 Faster!?
If you do some research on “time out” issues for windows 8, you’ll see a lot of information on this on the web.
