Coping files is very slow

Try to defrag you external hard drive, cek your hard drive wether there a bad ?
sometimes bad cluster can running slow for copying your data or else.sorry my english is poor.thank anyway

Windows is corrupt...
Sol = Reload Windows XP

you will need an original WinXP disk....insert the disk in the CD drive and restart...let it boot from the CD (to make changes to boot sequence make changes in BIOS)
once it boots from CD then repair you OS or install a fresh copy of the OS

It means your USB drive is failing. It's time to replace it.

Does the disk is an OEM disk?

1. Try creating another folder and coping the content from the original to the new folder on the USB drive.
You may have stopped the coping process inadvertently during the copy process.

shell32.dll file is very important windows system files.It control all users grapgical settings, icons, anything related to graphic user interface of the Operating system.If shell32.dll cannot be copied during installation,the system never gets to GUI mode.Try using a New CD/DVD.it will solve your problem.

your CD Rom drives could be dirty if if they are not copying files from the CD's correctly. tipically while installing an OS the CD's are moving alot of data very fast and can encounter errors if drives are dusty or dirty or even if the cd's have small scratches or smudges.
I recommend a CD/DVD drive cleaner disk, or fresh copies of your CD's.
You May also have to replace your drives, you can buy replacements fairly cheap from online retailers such as tigerdirect.com or on auction sites.

Please clarify what type of motherboard and its chip setup also did you upgrade with high end processor or any additional ram you increase or any change you made so recently.

If from the starting itself the problem for moving/coping or installation of the software is related to the compatibility of hardware system configuration - it can be the bus speed or faulty hard drive also system memory is fully loaded or enagaged by any other activity taking place in background, may it a virus or a trojan so please let me know the problem with history.
