Thx. Good advice. I should have mentioned that I did that. I also should have mentioned that it's 32 bit. This is not a HD problem. It's something in O/S or other backgnd pgms that just keep writing (reading?) disk.
Physical mem usage is pinned at 51%. It seems like it's paging to an order of stupidity. BTW HD is rattling now. It (almost) never stops.
Computer is Dell Insp 600M, 2g mem. First attempt was to boost mem from 512M to 2g. I thought that was the problem but it's apparently not.
As i typed this, disk stopped, at 24% mem now. but it will go back up, believe me. Is this Win 7? Does it mem page to infinitum (compared to XP)?
