Ever since I installed XP Service Pack, I've been getting a dialog box that says there are unreconguized versions of windows files. I insert the XP cd, it copies the files. Shorthly after I removed the CD, the message comes up again. I'm not sure if the SP caused this or if its something else. I completely formatted and re-installed windows but the same thing happens. I recently put in a new gf4 ti4200 could the drivers for this be the prob (45.23).
