SETUP error 0x80070570 Tried almost everything HELP

i Had a 32bit systeem but i upgraded my pc went from no graphic card to a 2GB,
and went from 2GB Ram to 4GB.. but i decided to change my 32bit to an 64bit..

and there is where the problem begun..

i started the installation and right by 81% he gave me the F'ing error!
so i restarted and tried it again.. but again with the same error!

i tried multiple CD's and made BOOT USB but nothing is makin a difference..
then i finally succeeded! but once i had al my drivers installed it started to give me blue screens..

i didnt know what this was until i searched the whole web and it said it maybe the cause of bad software..
so im back at it again reinstalling my software Windows 7..i even tried 8, but i dont like that one so i wanted to install 7 again but I CANT FIGURE OUT WHAT TO DO !

i unplucked dvi cable took out my graphic card..changed ram just like all the other forums said..but nothing is working for me!

so now im here and need help! can somebody please help me get my systeem back in functional mode!

cause im really tired of trying bout to throw this shit out the window!

i got a DDR2 Systeem.. Asus P5KPL-AM

THNKYOU!
