With an open link on my desktop I then go to open a new tab and the open link appears in the new tab instead of my homepage.
How do I make it so my homepage appears instead?
Wow, that's weird! This could be a number of things: it could be malware highjacking your homepage, I've even heard of fragmented system files causing weird behavior.
The easiest remedy would be to hi-light and delete the link from your desktop, then re-start the PC and see if that handles it.
Failing that, do a system restore to a point before this started to happen.
If still a problem, get Malware Bytes here: http://download.cnet.com/Malwarebytes-Anti-Malware/3000-8022_4-10804572.html
and run a full scan to see what it finds and handle whatever it comes up with.
If no luck, update your Anti-Virus and run a full virus scan and see if it finds anything (if you don't have an Anti-Virus, AVG is good).
If no joy, get CCleaner at http://download.cnet.com/ccleaner/
and do a registry scan (if it was malware, removing it may not have restored registry settings).
Also, with CCleaner, look at the options area and check out the Strat Up Programs. If anything you don;t recognize, disable them from starting up (there may be a rogue program that starts up and replaces the link on your desktop each time you remove it -- this will stop it from starting up when you start the PC).
After all this, do a thorough disk defrag using a good third party defragmenter that can address system files and will keep your disks defragmented (I have seen fragmented disks cause some really weird things). Here is a review done by Top 10 Reviews of the best defrag programs around: http://disk-defragmenter-software-review.toptenreviews.com/
. Check it out, get a free trial of one of the top placers and use it to defrag
your PC (including system files) see if that resolves your problem.
If still a problem there are more drastic measures available, but the above will probably resolve it.
Repost if need additional help.
