Modpacks won't launch

[Zach_Attack30]

When i launch any modpack, it closes the launcher. I get a loading circle. Then it never launches. I have windows 10, it worked before. I run compatibility, as admin. reinstall technic, reinstall java, and have reinstalled all graphics card drivers, upped the ram for java to 2.5/4 gbs, disabled stencil buffer. any help or an update to the launcher would be nice. BTW there are no crash reports. my PC specs are not too good, but like i said it worked before, here they are. 

Inspiron 3520 

Intel celeron cpu b820 1.7 ghz dual core

4gbs of ram
