Hi RDUNNILL,
Thank you for the quick response.
These came with a 305 watt power supply. This one was replaced with a Cooler Master 500 watt. I went to the Intel after I read your message and did the chipset update [fingers crossed the whole time]. No luck; didn't help.
The video adapter is an ATI Radeon X600. Intel, at first, offered an update but then did not recognize this adapter for the W7 application. Maybe you hit a "bingo" for me here. I'll nose around tomorrow for the best price on the Sapphire card you suggested. I'll report back after it's installed and let you know.
Thanks so much,
Mike
