Vista home premium worked fine on my computer for several months, I have an intel core 2 e4400 2.0ghz processor, 3 (1) gig kingston ram, intel dg965wh board, 250gb western digital harddrive, and a geforce 7600 graphics card. Vista home premium, norton antivirus, and office 2003

a few days ago my computer did somthing funny, it slowed down and when i put my coursor over the internet  connection icon it said server execution failed. after searching the web and my computer for answers i decided to reinstall vista, i did a clean install and the problem seemed to be fixed, when i looked at the icon it said not connected to a network instead of server execution failed.

Vista seemed to load fine and fast, but when it loaded completly the programs were very slow, When the welcome center loaded i clicked connect to the internet option, and after waiting about three minute for the connection options to load, i clicked connect to a wireless network and immediatly the program stopped responding.

Along with the internet troubles i tried to install some of my software like: pinnacle HDTV pci card, adobe, microsoft flight simulator. The issue with installing my software was it would install about three-fourths of the way and then hang, eventually i would have to stop the installation.

To fix these problems i tried to reinstalled vista and the same issues occur on first boot before i installed any software.

I booted into in safe mode and safe mode with networking with just the vital drivers and the same issues happened.

Thanks in advance for any help or insite that you could provide.
