Hi, I have a custom computer which was working fine for a few months, but then I started to get horizontal lines running across the monitor. They used to last a few seconds and go away, then they became more persistent, and now the entire display goes black after only a few minutes. All of my drivers are up to date. I don't really have time to do much before the screen goes black.

Any help would be greatly appreciated.
