Hello, so I recently installed an AMD Radeon HD 6700 primarily so that I could connect my PC to my TV through an HDMI cable. This worked great until a couple of days ago when it stopped for no apparent reason. I can't completely rule out that the HDMI hasn't gone bad (it's run through the wall, and while I could remove it and replace it, I'd rather not, it was a serious pain in the tuckus to get it in there...), but I think it's something with the card. I tried re-booting after it stopped working and it started working again (the windows boot screen came up on my TV), but then suddenly stopped again (got the "No Signal" text on the TV). I've also had some intermittent issues with games. While running TF2 everything suddenly got all neon (like the game was being played in a disco or something, all the blocks on the walls and floors were different neon colors) and then the cursor turned into a square of noise, etc...I haven't tried updating the drivers yet, but it's next on my list. I figured I'd check in here as well...thanks in advance for any help!

Oh, and here's the rest of my sysinfo:

Im thinking the card is overheating- Dell computers typically have terrible cooling properties

First off, update/re-install drivers. If problem persists try downloading some monitoring software such as realtemp or suchlike and after running TF2 for a reasonable amount of time check your max GPU temp.

If neither of those come up with anything I'd put money on the video memory being bad.
