Done all those.
Compaq Evo N610c 2.0ghz P4
2gb ram PC2700 Corsair (might be problem since specs say 2 x 512 max)
60gb 7200rpm Hitachi
XP Pro
I actually rip and burn movies using the above, but:
Sony VRD-VC20
LG GSA-E30L
Western Digital Mybook Pro 500gb
Problem started shortly after upgrading ram. I install the old ram and it lock up too. I have done 400+ movies in the last year without my computer locking up.
So this is driving me nuts. Right now I have resorted to putting the old ram in, wiping the hard drive and reinstalling Windows. We'll see if that works. If you have any more ideas...shoot them my way.
Thanks
