HIS ATI Radeon HD 5770 on Win 7 ^$bit driver issues....
OK Just built me a new sys :
Microsoft Windows 7 Home Premium 64-bit
Intel Core i5-750 Lynnfield 2.66GHz LGA 1156 95W Quad-Core Processor
GIGABYTE GA-P55-UD4P LGA 1156 Intel P55 ATX Intel Motherboard
HIS H577FN1GD ATI Radeon HD 5770 1GB 128-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card
CORSAIR CMPSU-750TX 750W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply

Thermaltake Silent 1156 CLP0552 92mm CPU Cooler For Intel Socket LGA1156
My issue is that my video card drivers are not working right I have tried old and new and still locking up the card when I play Dirt 2 or NFS Pro Street. Everything work great until I put a load on the video card like try to play a game or go full screen with online video (u-tube – CNN new) Yes I tried the 9.12 also nothing well fix it. I have removed all drivers first and all ATI Catalyst, too. I have installed the ATI Radeon HD 5770 on to my old XP Pro 32 bit with 9.12 XP drivers and it works great and can over clock the H out of it.
But Win 7 64 bit with no over clocking at all well not work worth a ^%$. Anyone have this issue? Did ya fix it? I am about to reload XP Pro 32 bit but would hate to do that.
