Oh yes. Black Viper is excellent advice.
My first thing I do whenever I redo a computer.
See above. I have decided to keep a fast secure computer, do anything but allow updates to happen.
All those things I read about and tried on XP were only minor improvements, some caused more problems than fixes.
What finally worked for me was to just wipeout the drive. Reinstall XP, install the software. Whatever you do, do NOT allow microsoft updates.
Now that same pc is perfectly stable and Im not about to going to update it to make it 'better' (and mega crashy again)
All my problems on that one used for DVR, happened after I let it update.
It is now firewalled from any outside connections, including microsoft. All it needs to know about is the LAN and the homemade antenna connected to its tuner card.
