So, a few days ago I was watching a video and my computer froze up and vertical red lines showed up on the screen. I did a hard reboot back into windows and everything was fine until about 10 minutes later when the same thing happened. I did another hard reboot but my PC wouldn't load past the "starting windows" splash page. Now I can only access safe mode.
From what I've read, I suppose this is a graphics card problem and it seems pretty common now with older 9800gt's. What I'm unsure of is how to replace a graphics card when all I can access is safe mode. I'm also considering switching to an ATI HD5770 so I'd like to know how to manage that chipset switch from safe mode.
My PC is a stock gateway FX4710 with:
Windows 7 64bit
6gb DDR2 RAM
Intel Core 2 quad Q9300 Quad-Core
Foxconn motherboard with Intel G33 chipset
Also, as a quick side question: Would an ATI radeon HD 5770 powercolor video card and an Antec BP550W powersupply work in my PC as replacement parts?
