Hello,

I am having a few problems with my GPU these days, I have an ASUS GTX780 DirectCuII, and these are the things that trouble me: when installed, I get flickering blue stripes on-screen. and my resolution is stuck at 800x600. Moreover, my monitor appears as a Genreic Non-Pnp monitor. When I try to install the drivers, it asks for the classic restart (nothing problem until...), by when I restart and log in, there is the same problem (stripes and low res) and GeForce Experience shows no drivers installed.

Please note:

1. Everything thing works fine and my Asus PB238Q is recognised as such through Maximus VI HERO onboard HDMI. 1920x1080 is possible.

2. I have read an issue with that being caused by VRMs or VRAM overheating. By hand, I felt that at the left side of the card, backplate side, it is hotter than in the center, where the core is. Is it normal.

3. When GPU is connected, display is connected through DVI. DisplayPort does not work (drivers?)

Anyhow, even though I am 15, this is not my first build, and I am open to any response from you at Tom's. However, I live in China, and although you may believe I am closer to the manufacturer's headquaters, but RMA is a pain over here, because the resellers have a long history of distrust and will often refuse RMA because of many frauds.

Thanks in advance !

By the way, keep up the amazing job you guys do, you really help more people than you think.

Full system spec please, but it sounds like a faulty card (or insufficient power).

Sorry, I forgot to include the full system specs, my bad:

CPU: i7 4770K stock speeds
CPU Cooler: H100i stock fans and speeks, but held only by 5 screws (3 are stripped)
Motherboard: Maximus VI Hero
RAM: Corsiar Vengeance 8GB 1600MHz CL9
GPU: Asus GTX 780 DirectCuII
SSD: Samsung 840 EVO 250GB
PSU: Corsair RM850 (Too much power for one GPU, although it makes weird buzzing sounds when the system is off but PSU is on)
Case: Thermaltake Urban S31 with stock fans
Fans: Two extra Coller Master fans powered by Molex

Any thoughts about PSU problems with the sound it makes?

If the PSU is buzzing then I would return it if its still in warranty.

Just two questions, I heard about old PSUs (RM is series is old) that do not support Haswell's energy-saving features buzz when the CPU enters a specific C-state, but even when the system is off?

Also, I find it strange that what would be the VRAM or the VRMs on the GPU feel warmer than the core at idle, and this seemed to cause issues vaguely ressembling those I encounter (seen on random, not well known forum, but several people were having the same issues, they were older GPUs). Is it normal?

It may seems that I want the answer that I want to hear, but I'm not that kind of person. I'm just scared they won't take he hardware back, especially since I'm French, (even though I speak chinese fluently :)  ) debating over RMA with chinese resellers in Shanghai is going to be hard, they're going to ask for proof, and that it wasn't my own fault (I'm pretty sure I grounded myself every time I touched something, could it be static electricity?).

Anyhow, if these questions fail to summon ideas, I won't persist and just get on with RMA'ing.

Just to simplify the RMA process, with the above information, do you believe it would be more of a PSU or a GPU issue? Should I RMA both?

Thanks in advance!

Its more likely a GPU issue. Can you test it in another computer to be sure?

That won't be possible, because this is my first personal build (all the others were for friends, random people, I created my own " mini company", that's how I got the money for this build). Maybe if I try other PCIE cables that came with the RM? Maybe plufg the modular cables in another PSU slot? That would not seem right, because the GTX 780's lights turn green just behind the the 8 and 6 pin slots, indicating power is indeed arriving correctly.

I guess I will just try my luck with the RMA. Just to be sure, is the very slight buzzing normal?

Not usually, but I still suspect the graphics card is faulty.

Ok, thank you so much for the answers and the time you spent for me. I'll go set up an RMA.
