Bad pool header

OK.. after that BSOD appeared first time, I had hard time reinstalling Windows but managed to succeed (now i apparently have 3 Windows Versions which of 2 i still have to delete, manually folder by folder because of administration rights, anyway thats a different story..)

my Problem is that during Start up and after I choose the first and correct Windows it gives me Option of Windows Startup Repair or Start Normal.. when i click Repair it starts that loading datas bar and then the BSOD..
when i choose Normal Start its only by luck I get to my Windows desktop, the other times it gets me to the WINDOWS word but only a red dot of the Windows Logo loads and it restarts my PC..
i could live like this, needing several Start up tries, but I'd of course like to fix it..

what ive done so far:
RAM check (i only have one RAM bar)
chkdsk
ccleaner registry cleaner

what else can i possibly do?

thanks

try SFC /SCANNNOW, this scans for broken or corrupt system files which i suspect may be the case.

A bugcheck 0x19 is usually down to a device driver, as there are no dumps to analyse it's impossible to say what it is though.

As you don't seem to have formatted your drive when reinstalling Windows I'd suggest you perform a http://www.sevenforums.com/tutorials/1649-clean-install-windows-7-a.html closely following the information in steps #7 and #8 to get your drive wiped properly to remove all previous Windows installations and prepared correctly for the new install.
