I put together a system for my little brother last night with a Gigabyte board and 2100+ that I had, along with a Gigabyte 5200. I put everything together, and it started fine the first few times. I restarted the computer to install XP, and there was no video. The monitor just goes into power save. I've tried the card in my computer and it works fine. Does anyone have any ideas about what might be causing this problem?
