k. i just installed my ati radeon 9500 pro cuple of ddays ago. When i did the system hung at after the post screen. The monitor would go black and would not load any further. I reinstalled winxp and it worked fine. Now I had to move a pci card from 1 slot to another becuase ati recommended it for air flow. My pc now does the same thing as it did with the hang! WEIRD! Any1 help me? The pci card wuz a dlink wireless dwl-650. I DONT WANT TO REINSTALL WINDOWS EVERY TIME I MOVE A COMPUTER COMPONENT!!
