Weird problem

[Lonman]

I have been running Hoster in my show for just over a year now on the same tower. Completely built for music - dual core pentium, 2 gb ram, mirrored hard drives, not on the interent, Hoster dedicated, Windows 2000 with SP4 & all updates. Works fine for the most part until recently...read on. The last few weeks or so, i've had songs that normally play just fine just STOP for absolutely no reason. Try to restart & they stop again. Reboot the computer & the file plays perfectly. A few days go by & other songs just stop. Files fine after a reboot. A full year went by without anything more than an occasional hiccup that a reboot wouldn't cure. Now it's becoming almost a nighltly event where some song is going to stop in the midst & need to either play off disc while rebooting the computer or move to another song.
Has anyone experienced anything remotely similar & what did you do (or would you try) to correct it?
