Hello guys, i need help.
So here's the problem, you see i bought my hd 7950 months ago and experience some graphic bug/glitch on some games. Example :
- In metro 2033 if look at the light source the light effect dissapear and theres some wird white smoke appear from it. eee..... it's hard to explain with words (i'll post a picture of it later, i'm at work right now).
- In Call of Juarez : Gunslinger, screen flicker at random.
- I got a black screen during windows boot or during gaming.
Its some example i can think of right now. So basically i thought it was the video card and i returned it to the distributor. 1 Month later (damn those distributor) i finally get my replacement they gave me the vapor-x model, the previous card it's just the dual-x model.
It turned out my replacement give me the same problem minus the black screen during windows boot up/gaming (need to test more to make sure). So i'm starting to think maybe it's not the GPU maybe it's something else, i already ruled out the probability of Bad rams stick and bad CPU.
The last 2 thing i need to check it's either the PSU or the motherboard it self. Now i need some input, is there something else i need to check beside the things that i have done ? any input is appreciated.
Oh yeah almost forgot, I've tried using my old HD 6870 and doesn't cause any problem at all. So i'm thinking maybe i got 2 bad video card in a row, or maybe because 7950 use more power it show that i got a bad power supply. Right now i' thinking to use the second PCI-E slot it's a 3.0@8x and see if the problem will persist.
