My new computer is homebuilt. I have windows 7 ultimate x64. This is what I have in Hardware. Asrock fatal1ty mobo i7-2600k nocture D-14 16 ram Sapphire toxic 6950 2GB 1 128gb ssd 3 hhd pioneer blu ray drive Did not overclock yet. Home network connection My programs and software was in Vista x64 which had no problems. Before I tranferred them to my new computer, I used the Windows 7 upgrade advisor and they all passed for compatiablity. Since I downloaded just the x64 ulitmate from here and everything works except explorer 9 x86 and some of my programs that worked just fine in vista x64 but not in windows 7 x64.I also having some trouble with my router. My IPS DSL has sent me 2 new routers and they sometimes don't hold the internet connection. I checked troubleshooting windows connection, it shows connected and cannot find problem. I constantly having to reset. IPS says my internet connection is working from their side and that maybe it's a software problem. I checked for spyware and viruses, there are none. Should I download both x86 and x64 and do a clean install and will that solve my internet connections and programs to work correctly?
