Welcome to the forums...
 
If you haven't tried driver 347.88 yet, give that one a try.

bdary, Thanks for the info. That did the trick.

Thanks, but it is still happening but not as bad. It seems most videos I try watching seem clear there are a few that show signs of pixelation, but I will watch this as I do more editing. I might try the next update to see if that fixes it.

I hope it works out

Do you happen to have a different PC to test your GPU in?  Maybe a friends or local PC repair shop.  Just to rule out the issue isn't the card itself.

I'm interested to hear what Asus gives you for a solution...
 
Have you tried going in to your BIOS and disabling the "on-board graphics"?  On some motherboards having this setting enabled while using a discrete GPU (your 740) can cause issue's.

You're welcome.
 
That's a bummer that your mobo doesn't support your 740.  It's worth a shot trying to disable the onboard graphics in BIOS, but after hearing what Asus said, it's unlikely it will help.  I'm curious to hear whether it did work or not...

Good to hear that everything is working now.  At least for the most part...
 
Just a side note.  If your video's run smooth and look good that are stored on your PC, but video's you watch online don't look so good, check to make sure you're browser is setup to use accelerated graphics (GPU rendering) rather than software rendering.

Interesting.  Keep us posted.
 
So this issue only happens when viewing video's online and everything is fine with video's already on your PC?

Update. So I have a request into B&H photo to see if i can find out where this computer came from and what was wrong with it. i don't have a problem with a computer being refurbished as long as it is done right and the first time around.
 
So now I contacted ASUS tech support via their website/chat. So now the tech (not really) is asking all of these questions about what board I was trying to use and what trouble shooting did I do. So I went through the whole thing with all the boards I went through and different drivers. So his answer was the "Approved" graphics board may not work because of who made the board even though it was a Nvidia GeForce graphics board... WHAT?.  If you are going to recommend a type of graphics board or any board that can be added to your computer, then IT SHOULD work. If the manufacture  is going to allow add ons to it's computer then you need to make sure these boards/add ons are going to work with hours of testing.
 
So now I found the problem... So with all of that schooling and years working with computers and testing equipment and working at Ford Aerospace, Paid off.  So I thought about the PCIe slot that the card was set at and figured that the problem was likely the lines coming off the buss of this slot because the video play from the onboard graphics was fine. So I decided to swap the graphics bd to the other pcie slot to see the results. Well i was right, it worked just fine, well up to this point.
 
So i will keep playing videos to see if things acts up again. And now the fun part comes trying to get B&H or ASUS to send me a replacement motherboard.... hahahahaha. I know it's funny but I am not going to go through of deleting all of those programs and then go through reloading everything....
 
Thanks. 

Well I'm contact with B&H (nothing from ASUS) and they had asked me for details again about the m/b and they said they will see what the can do, well I should say the customer rep. So I will see what they come up with.

Well right now I may have to run this computer until I can afford a new one which I build from scratch and screw these mfg's. It turns out that B&H will not repair this board or computer but they will take it back for a store credit.  WHAT?. And I also tried to ask ASUS if I could swap the motherboard and they told me that it was a 3rd party's board and not their problem. WOW!, what a bunch of A$$E$$.
