OK, so here's the deal. I had a perfectly running XP installation, but I decided to do a complete format/reinstall. While I was at it, I swapped out my 12X TDK burner for a new 40X Liteon. Well, after installing Windows and minimal apps, it is constantly freezing. It will freeze at totally random times and require me to restart. The ONLY THING that is different between now and before is the Liteon. The last time it froze, I looked at the drive and noticed the access light was on. Could something with the drive be causing these hangs? I have DMA enabled ("Use DMA if available") and it is operating in DMA mode 2. I just tried installing the new VIA drivers, and I'm going to see how that works. Anyone ever see this before? I'm trying to be brief in case it locks up on me again (this is my third attempt to post) but I can try to expand more tomorrow from work. THanks!
