What I mean by "off" is that random glitches happen every so often, and my computer seems to be dragging down. My Firefox default search changed, but I was able to change that back. The glitches consist of random system processes crashing and some of my more resource intensive programs crashing every so often (SWBFII, Adobe Photoshop CS3, for example)
I run a Windows XP MCE SP2 box w/ an Intel Pentium 4 (Prescott) @ 3.0GHz, 1 GB of DDR2 RAM and an ATI Radeon x1300 PCI (not Express, because HP was asinine enough to skip a PCI-E slot for the mobo, never mind an AGP) w/ 256MB of RAM for the card. If there's any more info you need me to post, please notify me and I'll be happy to update the post.
To satisfy anyone who is going to complain about the other aspects of the Prep guide, I use COMODO Firewall Pro for my FW, and I've installed every Microsoft update there is.
Finally, lately means in the last week.
