I currently have a desktop computer that I use primarily for watching downloaded movies & tv, and playing music (i.e. no gaming). Specs here: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01...

It says graphics are integrated, however in my Device Manager it says I have an NVIDIA GeForce 7900 GS card, which a friend of mine MAY have added at some point.

I used to have it hooked up to a tv that was only 720p, but now that I have a 1080p tv, I've been having issues. The colors are kind of off when it's just functioning as a computer (whites are sort of blue), shows don't look any better than when on my 720p tv, and I recently got a message saying that the video card wasn't getting enough power. And the sound is a bit weird, also, but that may be a different issue.

I did some research, and that NVIDIA card requires min 350-watt psu, and my computer only has 250.

My questions are:
1. Is the NVIDIA graphics card ok for my purposes, and if I just upgrade the power supply I should be good?
2. If NOT, could someone a) tell me why, and b) recommend what type of card/psu I would need to get? I know little about the types of interface needed/available, but can figure out how to open the case and unplug/plug things in.
3. Could this have anything to do with sound quality? I have the desktop hooked up to a soundbar that I've never had issues with until I switched to the 1080p tv.

Thanks for your help, in advance!

Well, The Intel GMA certainly doesn't support this resolutin very well .

Long story short : it's not exclusive to Nvidia, but you need to upgrade both GPU/PSU

How much money do you have for upgrading, and where do you live (country) ?

I live in the USA -- I was hoping to spend less than $150; I feel that if I go much above that I should maybe look into a new computer altogether.

And a 430W PSU (quality brand ) :

This should be within your budget ...
BEST LUCK :) 


Thank you for the answer -- one other question: that PSU looks large - does it fit within my computer case? I have very limited room, and am hoping to just replace the one that's in there already...

If your getting the hd6570, then you don't really need to upgrade the psu. It should run on that system even with the 250w psu. I used to run a sapphire hd6570 on a hp slimline with 220w psu. The min recommendation is just a way to make sure you have heaps of headroom for the rest of the system. Like they assume you are using highly overclocked i7/ Amd octacore systems with 20 sata drives etc.

With hd 6570, your total system power draw would be around 130- or even less.

Great help, you guys, thanks. Can you answer a question for me to satisfy my curiosity? Why do you think this has just become an issue? The same NVIDIA card has been in there for over a year, I believe, but it's only started behaving badly in the last month or so, about two weeks after I got my new tv.

Maybe because of poor quality components
