I recently cleaned(deleted the partition) out on my C : drive on my XP computer
it was on an HP pavillion vx74
the reason i did this was because i kept getting the registry error
Windows/system32/config/system error on my startup screen
so i installed a new OS
Which was WINDOWS XP SP2 Home edition OEM
it was the same OS as the OLD ONE but not the same version

OK HERE IS MY PROBLEM

after installing my new OS I found out i CANT INSTALL

MY PRINTER
MY SPEAKERS DONT WORK
THE VOLUME thingy on the taskbar doesnt show up(and there is no sound) !
and my INTERNET BROWSERS are acting wierd!!...
when i scroll down and up it looks like they are blinds !
what is wrong with my CPU?
does it need updates?

Install Windows XP with Service Pack 2 AFTER FORMATTING the C: drive. Then install all the motherboard drivers i.e. chipset, graphics, audio, LAN, etc.. If you don't have the motherboard CD, then go to http://www.hp.com and download it. Install any additional driver required by your system. Then try installing the printer. It should work.
