Font gets bigger and computer runs really slowly on internet...

Medium Priority
Last Modified: 2013-12-29
I was using MSN messenger last night, when all of a sudden my computer started getting really jumpy. For instance, when I type the text doesn't appear smoothly on my screen but there are short delays and then batches of text will appear.

I tried rebooting, and at first the problem seems to have gone away but then if I go to certain websites then the font of them is bigger than normal (eg. google, or any Microsoft site...using Messenger also causes the problems), and my computer again runs slowly and any typing again only appears in batches. Also, any website I then link to directly also appears in large font, though it's virtually impossible for me to load a web page then and I have to close IE. It only happens in that windwo though. For instance, I currently have one window open running like this, but this page is typig fine. I have rebooted a few times since, have run ad-aware and Spybot - Search & Destroy, and both have come up clean. I've also deleted all cookies and temp internet files, but nothing seems to be working.

Has anyone any idea what may have happened? I'm pretty sure I didn't change any settings last night as I was literally just chatting on MSN.  Also, I'm fairly computer illiterate, so if you could suggest things in easy speak I'd be very grateful!!

Watch Question


Has anyone got any ideas at all please? I think the problem's getting worse as the font here is now bigger, and the font on MSN.co.uk and google is even bigger than it was.  Also, pages are now starting to just freeze...my hotmail inbox does everytime I open it, and this page wouldn't let me post what I typed 5 minutes ago, clicking submit was just ineffective.

I did a virus scan, but that didn't find anything. I'm totally at a loss! :-(
Can you start with a command prompt by depressing F8 at Bootup.
Then at the C:\ prompt type:
scanreg /restore    (note space between g and / )
Press enter, & select a date prior to your font problem.   Now reboot.      
Any improvement?

You could download and run Lavalys "EVEREST Free Edition 2.20" from here:

Then use it to check your CPU temperature and other parameters.
Any signs of overheating?

Another suggestion is to download and install the RAM tester memtest86+

> have run ad-aware and Spybot - Search & Destroy <

Ok, but how about virus scanning, there may well be a problem here. Even though you're probably running your own scanner, suggest you try at least two of these three, free virus scanners, 'pandasoftware' is particularly good. [No one scanner seems to capture 'everything']:


Can you reach Safe mode by rebooting tapping F8 key rapidly until the dos screen appears, and how stable is the computer ?

If you still have the problem after following the suggestions above, and there are no other comments incoming, suggest you download, install and run HijackThis ( v1.99.0 ) from here.  If you've not used HJT before, please post back for advice (there are some instructions included):



I've done the scanreg /restore, and that seems to have worked (touch wood!).  Would that have just hidden the problem as it were, or is that a permanent solution?

Also, the only thing I can think of that I perhaps did to cause this was that I attempted to defrag my c drive but it kept restarting at 1%, so I stopped. I think I read somewhere that you shouldn't abort during defragmentation, but my computer seeminly has some programmes that were running and causing this restart, and I don't know what they were to stop them fom doing it!  Could aborting a defrag have screwed up the registry in this way?

And thanks for the help Jonvee!

The scanreg /restore would have exchanged the registry copy with a good one as you're probably aware.  It may well be ok now, but best if you don't attempt any 'heroics' until after you've rebooted tomorrow and Windows has given you yet another new Registry copy.  Suggest just monitoring the PC for 2 or 3 days, while you're using it.  
It's conceivable the registry was corrupted somehow when you were using MSN, but maybe not.  
Cancelling Defrag part way thru should not have caused the problem.

The reason for Defrag restarting at 1% may well be due to 'something' writing to the HDD.  If the PC is ok for a couple of days, suggest you then bootup in Safe mode then try Defrag, should be fine.  [Safe mode by depressing F8 at Bootup]

When you're ready to run Defrag again you could first run ScanDisk, then Defrag.  But before you even do that, you may like to review this article.   In particular, scroll about halfway down to sub-heading "Sometimes Defrag hangs .."

"Defragmenting Your Drive":

Maybe you could now confirm if you are satisfied with all of the above comments and we can complete this thread, or whether you require further assistance.   Thanks.


whoops, sorry. I've been busy over the weekend and forgot to finish this thread.

Your help has been great jonvee, my computer seems to be running fine, and the defrag in safe mode was also successful. Thanks!

No problem, and thank you.     Glad that the defrag in Safe mode was successful.
