problem with boot, maybe vid card maybe psu?

ive managed to get it fixed , reason is the sata wire is getting loose after you plug it in all the time, even 1 mm lose and it wont read the hdd. i am now running the case without the side window as it would only move that wire. anyways. it works for now.

You can also try something called Super GRUB disc, which will let you restore/fix the master boot record fairly easily.
