Need Urgent Help With My Computer!!!

Alrighty, here is my big question/challenge to the Tom's Hardware Community! My Build is Currently :
-Intel Core 2 Quad Q9400 2.66Ghz processor
-4gb 800mhz RAM
-DG35DC ot something motherboard (its really old lol)
-Antec 550W PSU
-1 TB hard drive no ssd
-Pioneer DVD-RW
-XFX Double D Black Edition HD R7770
-Zalman Cpu Fan (Its a "fan" of copper discs with a 120mm fan in the middle)
-GR-one In Win Case

Now i am on track to get $400 worth of upgrades to my mobo, cpu, and ram. (i want to get i5-4670k OR i5-3570k, Sniper Series 8GB RAM, and a decent mobo that i am still searching for) but my pc is doing this very fatal crash that doesn't let me see anything on my main display, yet i can still use my other display and i can still use skype if i blindly click on my desktop for the icon... heres an example:

Here is my question(s): 1. Is this a GPU Problem?
2. Should I buy the intended upgrades for my otherwise outdated build, or should i get a new GPU? Which is more likely to stop this problem?

PS: This crash happens all of the time, it doesn't matter if i am gaming on League of Legends or if i am sitting there on Facebook/idle. it will just flash and my main display will just flicker like in the photo above.

Any questions i will be more than happy to give more information, although i think i covered most of it haha :)

  1. It could be the 7770, but i'm thinking power supply failing. Is there a spare you can try? Can you have a friend run the 7770 for a day?

    It would have to be letting them try it out for a week because this occurrence is almost bipolar, it won't happen at all for a few days at a time, then all of sudden (like today when i finally posted about it) it will do it all day... i will keep this idea as a last resort because this is my only source of entertainment lol.
  3. Is anything overheating? Maybe a good de-dust cleaning is in order.

    i dust it every week, and nothing overheats i have all fans maxed out and i am using a temperature monitor with the temp's not even hitting high at all. :(

  5. Thanks, Just checking, how about using another display port for the main display? From the card.
  6. I have seen that screen before. It was a bad graphics card. Try another card and see if it still happens.
  7. Sorry I haven't replied, but i actually found the problem. In AMD's "Catalyst" Program there is an option or an alternate DVI freqeuncy. I clicked the checkbox and the crashes dropped by 90%.
