Hi, recently my computer has begun showing green artifacts during boot (2 long strips of it down the screen) and upon getting to desktop, there are tiled green artifacts across the screen. After 10-20 seconds, the computer fails to respond and shuts itself down or blue screens.
Switching to safe mode, it boots fine etc and acts normal. However artifacts did appear while using firefox, but the system recovered itself and stated that the driver failed.
Previously I did a quick reformat but didn't seem to change it, would doing a full format be useful here to clear all drivers etc or is this an issue with the GPU/PSU?
