Finally got my 8800gt back from RMA and it artifacts, freezes and nvlddmkm error

Question

The problems I am getting is the same before sending the card for RMA. Here's the problem with the card. It artifacts in games and freezed requiring a total system restart, sometimes if i am lucky i can call up task manager and end the game. Sometimes the screen would go black and you can hear the music in the background continue to play and sometimes the music loops over and over again. I can not get into playing any game now. It also artifacts on the windows desktop as well. Its so bad that it even happens when using Media player classic. it would just freeze and black out then the Nvlddmkm error would pop up and said it has recovered.
this card worked flawlessly for the first few months that i own it and then this happens. i believe its relating to bad memory on the graphics card, maybe??? i also have a msi 7300LE that i used during the RMA period, it has work without a glitch playing games and videos. it never crashed on me once. i was so glad to get my card back from RMA but only to be let down again.
The RMA process was pretty easy, it took less than a month. i believe they replaced the fan and top cover on my card for me, but i think its a memory problem on the card. I am not sure if they tested it before sending it back to me because the problem is still there.
Should i do a second rma, its going to take another month.

Have you tested the VGA in another machine?
Have you tried with better PSU yet? {APEVIA are known as junk PSU}
Thats why I rma it in the first place, cause I didnt have another machine I can test it on. so I figure MSI will be able to determine if its working or not. I dont have another power supply I can test it on. Do you think if i bring the graphics card to best buy or circuit city do you think they will do a test run on the card for me for free?
I am still leaning more toward a graphics card problem than a psu problem. Yesterday I was messing around with Riva Tuner I underclock my speeds to 590/14XX linked and 890. I was able to get into game play for like two minutes and then bam it freezed again. the core temp is at 45c to 55c. So its not  related to heat issues.
