NEED MPC 2k REPAIR.... HELP!

I've had my MP for about 6 years and all of a sudden I'm havin' issues. I've gone thru a couple of jaz and zip drives thinkin' the issue was with my external devices...NAH! The MP fritzes out when it's time to load partition C on any disk, it fritzes when I'm tryin' to save a PGM or SEQ. I dunno what to do because my MP is the center of my STU (studio). I'm in need of some assistance, if any of you have had this prob and know what to do, holla at the kid.....PLEASE!

try rebooting your O.S.

maybe the memory modules are fried, it happens quite often

some memory don't last very long (a few years)

I appreciate the LIL' BIT of help I've gotten to this prob I'm havin'.
I'm still workin' on it. Right now, I'm tryn' to cop somebodies old one for parts. Thanx fellas, PEACE
