Internet working, but does nothing when I "send" information on certain sites

I recently got my Toshiba satellite repaired by having a new hard drive put in. Ever since then, my internet is working except for when I try to send information. For example, when I enter my username for my banking website and hit send, nothing happens. When I try to purchase something, and hit purchase, nothing happens. When I try to print an internet coupon and hit print, nothing happens. But when I log into sites like this one, or yahoo or facebook, I can get in. What is wrong?? Please help, as I need to access my bank account and pay bills!

Thanks!

 

I had to get the recovery media from Toshiba and it was the Windows 7 home premium 64 bit. I have listed that I have Adobe flash player plug in 10 and Adobe flash player 11 active 64bit, Adobe reader and Adobe air installed. Should I remover the Adobe 10?

I have Java 6 update 30 installed. When I went to check my Java to update it, the Java installer said that...

"We have detected you may be viewing this page in a 32-bit browser.If you use 32-bit and 64-bit browsers interchangeably, you will need to install both 32-bit and 64-bit Java in order to have the Java plug-in for both browsers."

I am confused about that.

I don't know what the service pack it is, where would I find that at?

Yesterday, I was able to get onto my online banking, but when I first entered my user name and clicked enter, it did nothing. I refreshed the page, and tried again and it worked. I was able to get to the next page where I enter my passcode, but when I hit enter it didn't do anything. I refreshed the page, and it got me into my account. I tried to do this again today and it didn't work.

 

Ok, I updated my Java, and installed both the 64 and 32 bit as it suggested. I have IE 9 which says it is a 256-bit. Tried again to get onto my banking website, and when I type in my user name and hit enter, it changes it to asteriks, but does not forward to the next page. Is it the IE 9 that is messing it all up?

I've even tried installing google chrome. and while it lets me get onto the bank website, it tells me that I am having too many long running scripts. I don't know what to do, I have both the 32bit and 64 bit javas installed. Why aren't my javas working?
