Oh boy, running intensive applicatons on ME is a big NO NO! :)
Of course SDRAM won't be hard to find, it's not that old... Even SIMM's can still be found out places like tigerdirect...
Now, about your freezing problem... It's either bad RAM or the bad windows ME OS... Both can freeze the same way :p... I'm guessing it's the OS...
To go over what everyone else has basically said:
1. Defrag
2. Disk Cleanup (should be in windows 9x, been forever since I used 9x...)
3. Keep running programs and tasks at a minimum
4 Throw another stick of ram in there (there are programs out there that can tell you your motherboards RAM specifications, many are boot disks so it doesn't matter what OS you got)
If all else fails, downgrading to 98SE is the best option... If I were you I would just forget the extra stick of ram and just downgrade... Or do both...
