I need troubleshoting help.

[Pepec9124]

I have interferences on my screen, some horizontal lines moving vertically and it's very annoying.

It's mostly visible when it's displaying dark images.

 

I've done some things to eliminate some potential causes. My best shot is PCI-E GPU or PSU.

 

I've taken out GPU from my PC and now I'm running it without issuses on integrated HD2000. So is it my PSU having problems with power generation with additional GPU or is it my GPU sucking ? I've got 2 weeks of warranty left :doh:

 

Clue: My PSU is not rated with some certificates like 80 PLUS or etc. It's cheap i-tec 700W. It might be most stupid thing I've done, instead of buying good 500W with certificate I bought some cheap shit.

 

Edit. Typo in thread name again.

I dont think its a power problem, otherwise you would have BSOD failures or even power downs during your gameplay. Its definitely a graphics card problem, take it back and use that warranty.

Thanks, I will send it back tomorrow then.

Hmm , what spec is your PSU? I wouldn't count that PSU out....just yet. Ideally I would replace that PSU with something good in any case.

I-tec Power Gamer 700w, anyway it`s fine now with integrated GPU. My graphics card has 116w tdp so with core i3 it should not have so much trouble that it would interfere with display.

BTW it is connected via analogue cable which I have manually coated today :p

 

Edit. 484w on 12v lane and 200w on the rest.

Do you have the option to put the GPU into another PC to test (maybe at the shop)? It would determine if the GPU has a problem or not. If possible, hook it up with the same monitor you use now.

Do you have this issue only when playing a game (when the GPU is under load) or always?

Also, don't rule out your motherboard, it's unlikely but it could have an issue on it's PCI lanes.

I've` got this issue with my GPU no matter the load. I can check it on friend's PC. He has similar specs, just with AMD CPU and good PSU.

If it happens no matter what load the card the is on, you can "almost" rule out the PSU. But a test will tell...

It was the PSU, thanks for help. My HDD is down.
