Windows 7 Professional Won’t Update

I’ve been working hard this weekend, trying to update my computer. The keyboard is acting up, freezing a few keys. I’ve done everything to fix the problem but with zero success. It has come to my attention that it might be the operating system itself.

I have an Acer Aspire 5335. Never had issues until this weekend. Important updates were requested by Microsoft.

Then the unusual occured. The operating system gave me a 7601 issue, stating that it was not an original copy. Very odd because I have a product key associated with the current operating system.

I guess that an upgrade is needed asap. Now my computer is sitting useless, while my work gets back tracked once again. I’m not sure what is the next option as I keep researching the internet for a real solution.

By the way! The windows anytime upgrade indicated that the product key was outdated.

I guess that a new product key is required in order to continue the update but where can I find the current product key?

My computer is running on 32bits.
