Hey there, New to these forums, but need some help with my HTPC. Thanks ahead of time! Out of nowhere I received messages saying that multiple appdata local files were corrupt and then all programs became non-responsive or would start but became non-responding after a few seconds. I ran chkdsk and after some time it finished repairing the errors. However, now my system gave me 4 warnings saying that none of my security features were working. I use AVG Internet Security 2012. When I click on the AVG Icons or try and repair by clicking on the warnings, nothing happens. I have read that I should reinstall Windows 7 Ultimate to solve the problem. Sadly I did not partition my hard drive went I built the PC, and of course I do not want to lose any programs, files, etc. So what are my best options? 1. Back up my hard drive and bring everything back over once Windows in reinstalled? 2. Buy an SSD drive for one of my extra bays and install Windows 7 Ult there? Is this even an option since I already have Windows 7 Ult on my PC? 3. Is it possible to partition the drive and move Windows to this section? Then reinstall Windows without affecting other programs and files? 4. Is reinstalling Windows even the solution to this problem? Please let me know what your thoughts are and please give any suggestions that I have not suggested above. I appreciate any help. Thanks!!
