Computer starts up fine but freezes a few minutes later

Hi, I would like to start off by my PC's specifications, I have a HP Mini 210-3002SA notebook, originally it had a 250GB Hard drive and a 1GB RAM, Windows 7 Started OS, my previous hard drive got corrupt :eek: and stopped working so I purchased a new 1TB hard drive :cool: in which the windows 7 starter was installed by a technician and I had upgraded the RAM to a 2GB:cool: . My PC was working fine until recently it kept coming up with an error for a missing Conduit BackgroundContainer.DLL :eek: file every time I started the PC, so I downloaded auto run from Microsoft website and had deleted the missing DLL file and checked the PC for viruses and there was one virus from Bettersurf and my antivirus software removed it. I started my PC again and it starts up fine :) but it freezes when I open any applications, :( SafeMode will not let me run the antivirus with or without networking :confused: and I have no idea what's happening.:confused: I uninstalled recently downloaded programs which were MS Visual Basic and Team Viewer before deleting the entire conduit file using auto run. So please :( please :( please :( help me... I appreciate your efforts and your help :up: :up: :up:...

PS. Since the new hard drive had only the window 7 OS installed, I had installed all the necessary software drivers that originally came installed in the PC from the HP Website using a USB for transferring the drivers from one PC to another until Wi-Fi was enabled. It still was not like how it' was originally with the speakers making crackling sounds. The applications freeze all the time saying Not Responding.

PS. Again, I have installed the latest windows update available...

Thank you very very much to whoever that replies to this thread :rolleyes:
