Please post latest minidump file (c:\windows\minidump).

how do i create one?

Are you using latest DT version?

Control Panel -> System -> Advanced -> Settings (the 3rd one) -> Drop-down list at bottom -> 2nd option

Now install DT again and after reboot let it BSOD.

Well, when i went to install DT an error appeared when sptd was installing that said "failed to open service key" and then the installation stops and says "sptd setup error code 5" and closes.

Please check this manual regarding service key.

i have decided to give up on daemon tools because a program that takes this long to get working just isn't worth it

Well, it normally doesn't take long, it only takes a bit longer when system has problems.
