Take either the 4th one or the 6th one from the realtek site.

Inform us about the situation.

Just some extra info, today when i got home from diving my computer was off, although i left it on, i was only gone for about 4 hours and it actually refused to start when i tried, the fans and lights started, but nothing happened except that, and sometimes it would just give up and stop working, i used the off/on switch and when i then tried to start it it instantly turned off, and when i tried again, it suddenly worked.

Looks like it's hardware.

Try to enter your BIOS/UEFI and set it to defaults and see if w7 will start. The 0x7f sometimes is cause by overclocking.

Check the power cord, and the power supply unit. If you on the power button, does the fan of the power supply unit work?

Is the switch on the PSU "on"?

After a while I can now turn it on again. If I don't set the Bios to Asus optimal I can't do anything without a BSOD

Maybe the overload protection in the PSU is cutting it off due to a short or something like that.

Have you checked all the power connectors in your case are securely seated?

Your motherboard may be grounding out, you'll need to remove it from the case to test it.

After all the troubleshooting so far, I would test with a new or known good PSU.
What brand is your current PSU?
