okay here is my deal im not sure if im posting in the right forum.well this is my thing i bought my computer which is a comaq presiro with windows xp on it already.well me and my gf wanted to try vista so we went a bought a vista disk and put it in our computer and booted the computer up well we deleted the partition space in drive c: and copied the vista on that after deleting.anyway we hate vista so bad its so crappy it freezes and its slow and crashes our computer. So we wanted to put xp back on here and i have tried everything in my mind to get this to work right.but we deleted the partion again and re-installed xp But....im missing alot of stuff. like for example,stuff in my device manager,modem,ports,ect and it wont even detect my modem or a internet connection at all.so i had to install vista again. and im trying to find a way to get xp to work can anyone give me any advice please. thanks
