So I just got a replacement Gpu because my last one burned whatever black chip is on the backside of the card (some kind of voltage control?) and this one shows strange artifacts from time to time, which are always fixed by removing and re-plugging the hdmi cable. I am also getting strange feedback through my speakers, like a static buzz that occurs randomly for no reason every so often. At first I thought it was just because the speakers are really old, but now I am wondering if my psu is causing these issues, or is it just bad luck that I have bad speakers, and a second bad gpu?
Specs: Fx-6300, Radeon HD 7950, MSI 970a-g46, Corsair CX 600w
PS. I know my mobo and psu aren't the greatest, but when you don't have a lot of cash at your disposal, your option to buy high quality parts is a bit limited. I have learned that buying low quality mobos and PSUs is a bad idea, so I will never do it again, even if it takes me much longer to afford a new pc.
Test everything outside the case just because I have a sneaking suspicion that the issue may be bad earth related.
Also try another hdmi cable or other output cable - dvi etc..
Plus dont be disheartened in your parts - CX600's are ok. Much better than what is lurking in some peoples systems. In saying that if the unit is faulty you'd best be rma'ing it asap.
Best way to see if any component is faulty is to test it in another system. ~ test all parts if you can starting with the gpu then psu etc.
On a side note is not uncommon for rma replacement cards to be duds as well.
That's the problem, this is the only non portable system in my house so I have nothing to test it with. I'll pick up a replacement dvi cable though. Other than the strange speaker feedback, and the strange screen artifacts from time to time, I have no issue at all with this machine. The speakers give off a lot static sound sometimes when turning the pc off, and they give off static sometimes even with the computer is off. Is it a grounding issue?
Edit: I know my PSU isn't absolutely awful, but it certainly isn't anything to brag home about. I know plenty of people who have a CX series PSU and use it with no issues, but I'm still weary about my decision to purchase a low-mid end PSU and mobo, when those parts are so vital to system stability.
