He was on this website softcore or something where he downloaded mods for terraria that weren't in the mod loader. And the screen went black and I checked it out and changed the DVI cable and then restarted it with the button on the front panel and it booted to post with no issue. I told him and he went to log in and he claims to have been able to open a program then it went black and when restarting there were purple artifacts and it post looped. I spent hours checking things and using the monitor on other computers and other cords and etc. I eventually narrowed it down to the graphics card, So now, I switched the graphics card with a Geforce 745, Which I don't really trust will support what He likes to play. Not to mention the task of installing the right drivers as it used to use AMD and now I put an Nvidia card in there. But I just really want it to be fixed and back to normal and I don't want to label the card as useless just yet. I recorded the current state of it when you boot it, Also apparently there used to be RGB on it but I don't know.
Pretty simple really, you install any mod that causes issues, you uninstall and start from fresh.
And this is an AMD forum, if you want help with Nv graphiics , go to to their forums.
And troublshooting through a thied party is a waste of time. you cannot supply all relevant info that may be required.
If you read the info required ?
