Hi kirsty!
Please, try to remove outbyte pcrepair altogether.
If you bought a license for it, note it down (before you remove it).
If bsods will continue after this, run a memtest.
You can find 4 tutorials in the hardware subforum (in this same sysnative forum).
The one usually recommended is PASSMARK memtest86 (the free version), but I prefer HCIDesign memtest (the free version).
You can try both, obviously.
