Instability from system age, games where crashing a bit more then usuall and alot more then a fresh install would.
I had to install sp2 for win xp 64 bit, the .nets and there sp's, some 50 other updates for windows, gfx and sound drivers, drivers for the keyboard and mouse, steam and every game in it, starting fresh with steam so I have to redl everything already got hl dl'ed and sc installed.
and the couple days thing was if something went wrong and had to reinstall again, I had 32bit xp randomly die like a day or so after installing it, but the last couple installs of windows have been fine.
^ but it is probably going to take me a few days to re'dl all of my games in steam...
