I just installed the UGA-125 on my HP computer with Q45/43 chipset and everything was working somewhat fine as I had my three monitors working, albeit not to my desired resolution. However, when I restarted my computer to see if the settings would work, my computer goes into a start-up loop where I log into Windows Xp and it begins to load the programs and then suddenly restarts. If I remove the USB cable for the adapter I can get the computer to work properly and then replug the adapters to get the displays correct. I am using the latest drivers that I downloaded today. Is there any reason why UGA-125 would cause a re-start loop?
If I can resolve this issue I plan on upgrading to the higher resolution adapter.
