Well with my Experience...
I hav PIII 64 SD RAM , 1 Ghz PC and am/was using Win ME till last month..
It was the best OS until i got NET Connection..
Well ME crashes when we try to surf .. i have even experienced this in fresh install...
So what i will suggest is ..either Upgrade to XP if ur RAM and CPU permits...else..roll back to 98..which am currently using...
Regards,
DIpen
