According to the Soyo compatibilty chart, this motherboard can support an XP 3000+. I just installed a 2800+ and have several problems. 1. The BIOS won't recognize it. Will the BIOS patch that fixes 3000's not being recognized also fix this? 2. There is ZERO increase over my 2000+. Is that because of the BIOS? 3. When the PC case cover is on, the system becomes unstable? According to the Soyo hardware monitor it's not overheating but I can't think of anything else it could be. Any suggestions on these?
