Troubleshooting Internet Explorer on Vista Locking Up or Running Slowly
If you are having issues with Internet Explorer running extremely slow, crashing, locking up, or just generally behaving badly, there are a couple of troubleshooting steps that you can follow to likely fix the problem. And no, I'm not going to just tell you to install Firefox.
Of course I'll suggest it, since Firefox is an excellent browser… But for most people, Internet Explorer works just fine and does everything you need. So let's get that browser working properly again!
Test Using Internet Explorer's "Safe Mode"
The first thing you can do is run Internet Explorer with all the add-ons (or plugins) disabled, which will help us determine if the problem is caused by an add-on or somewhere else in the system.
You can find the "Internet Explorer (No Add-ons)" menu item under Accessories \ System Tools in the start menu, or you can launch IE from the command line with the -extoff switch like this: iexplore.exe -extoff
If the performance / locking up problems are gone, then you know you are dealing with a problem add-on, most likely one of those toolbars that seem to be attached to every shareware application.
Disable Internet Explorer Add-Ons
Close the "safe mode" IE window, and then open Internet Explorer normally. Click on the Tools menu, then Manage Add-ons, and then Enable or Disable Add-ons:
In this screen, you can select Add-ons and then choose to Disable them one by one using the radio button at the bottom.
The default list shows only the add-ons that are currently loaded, so you should also check out the other selections, because the problem add-on might not be set to load on startup.
In order to properly troubleshoot, it would be easiest to disable all of them, and then re-enable one by one until you find the problem add-on (which you should uninstall if possible)
Reset All Internet Explorer Settings to Default
If you are having too many issues, you can always just completely wipe the slate clean and start over with a fresh Internet Explorer configuration, which should fix the vast majority of issues.
Open the Internet Properties dialog by finding the Internet Options section in Control Panel (just type internet into the search box)
(Note that you can also right-click on the Internet Explorer icon on the desktop and choose Properties, or just use Tools \ Options if you are able to open Internet Explorer)
Once there, choose the Advanced tab, and then click on that Reset button. Everything will be completely wiped clean, but it's likely you'll have better luck browsing from then on.
Scan Your Computer for Viruses/Spyware
This should be a given… anytime your computer is running extremely slow you should scan for viruses and spyware.
Disable Receive Window Auto-Tuning
If none of those fixes the problem, and you are just having a really slow browsing experience only on your Vista computer, the problem could very well be due to the network auto-tuning feature in Windows Vista which is incompatible with some routers.
Open up an administrator mode command prompt (right click on command prompt and choose Run as Administrator), and then type in the following command.
netsh int tcp set global autotuninglevel=disabled
You'll have to reboot the computer after making this change. Note that the same change also can help fix problems with copying large files.
Reboot Your Router!
I can't tell you the number of times that my browsing experience slowed down to a crawl because my Linksys router needed a reboot. This seems to happen a lot more if you are downloading torrents as well.
If you are still having problems at this point, head on over to our forum and ask our growing community of helpful geeks.
I had no idea you could reset IE to default, great tip!
Love the last pic
Ahh.. I always forgot that router tip! Thanks for reminding me!
Excellent tip as always!
A couple people I work with had problems with IE locking up, running extremely slow, and crashing a few weeks ago. I uninstalled the Google Toolbar and it fixed both of them! When they reinstalled the latest version it worked fine.
That last picture is great!
Any consumer ipv4 (NAT-based) router should be restarted at least once every few weeks. With some routers (like the more recent LinkSys), I would recommend power cycling even more frequently. The problem is that most routers have slight memory leaks in their firmware. The NAT table is a very oft-queried component in IPv4 routers, so this is often where the problem shows up. The reason the issue is exacerbated by torrenting is because BitTorrent (as with most P2P software) opens up a large number of short-lived connections to different destinations. This causes a *massive* amount of load on the NAT.
Even using m0n0wall, which is vastly superior to consumer routers, I still have to reboot once every few months.
The plugins part is exactly what I did for my IE7 installation on WinXP long time ago: [mod-removed]
However, I didn't know the reset tip (for some reason my particular IE7 installation gives javascript errors on sites where other people's IE7 doesn't). I will try to reset tip to see if that works..
I confirm that the Reset trick fixed my IE big time. Not only have I stopped getting these stupid Javascript errors, there's another thing that has been fixed.
It used to be so that IE7 would display any images in webpages in a blurry (less resolution?) manner with jagged edges.
That is fixed now.
The reason the router needs resetting with p2p is that there are too many open connections. Routers usually have a default timeout for open connection which is too long for p2p networking.
In most routers (including the linksys ones) you can't change this setting, but alternative router firmware (such as the ones covered by lifehacker here: http://lifehacker.com/344765/t.....ith-tomato) will allow you to set this to a shorter time, thus, eliminating this problem. (and usually - this will make your p2p networking faster and more efficient.)
For many of my acquaintances who experience gradual slowing of their computer and particularly their internet, I recommend the checking for spyware as a first step. Many think that their virus protection automatically scans for spyware and catches it all. It may not. Running a separate spyware program will often dramatically improve their functioning. I personally like the Ad-Aware SE Personal one (it's free), but there are many out there or they can upgrade their virus protection to include spyware. Thanks for the additional tips to try.
Thanks for this valuable information……
