performance issues going from x86 to x64

[jsmason11]

I have an HTPC that I use for watching Netflix and hulu and photo editing. I have been using windows 7 Pro x86 for about 3 weeks flawlessly. I have done a clean install to Pro x64 and now my video quality in Netflix has become almost unwatchable. I just did internet speed test with Speedtest.net - The Global Broadband Speed Test and my average is 15Mbps. What could be the problem?

I can only say I've no problems with Netflix videos (I'm Win7 Ultimate x64). Install latest vidcard drivers? Need latest mobo drivers? BIOS flash?

I did the vid card, how do you find mobo and bios flash

Go into Device Manager and uninstall the Display Adapter > reboot and let Windows install the default VGA drivers. Make sure you've downloaded the correct vidcard drivers and noted their location. Then Device Manager > right click Display Adapter > Update Driver software
