Once a day (I kill it at night). I use WinME and can't complain (I seem to be in the minority). I also use win 2k and it is equally stable. If your system is crash happy, go get real hardware and throw all that generic crap in the trash! If you do and its still buggy, get tech support for the hardware you do have and get them to fix the crap! The extra money you will spend is worth the trouble. There are few things that bother me more than people complaining about system failure and then having them tell me that they have 192MB consisting of three mix matched 64mb generic pc100/pc133 ram sticks, or some crappy MB, or both. Oh yea... I have this nitro abacus running overclocked to 1zillion GHz, but it crashes all the time? damn Microsoft? blah, blah, blah? my rant is over? you can go now.
