7950 vaporx issue or potential monitor problem

post #1 of 13
Thread Starter 
Hello,

Haven't been here for some time but my setup has started to act really wacky lately thanks to a power outage. After the boot I wanted to play some games and whammy I got a similar screen to what is on Picture 1. After numerous reboots, I took out the mobo cmos battery, later I updated the latest AMD driver(had to use an older version for csgo because of resolution stretching)the games were playable so I figured my PC stopped it's period. So that was a week ago.

So my monitor BENQ XL2411t or GPU(7950 vaporx) not a 100% sure which of them is broken has really acted up. I have a dual monitor setup, the second monitor is some fujitsu hunk of poop.


Last night I did a reboot, and right after the bootup had finished I got this black lined mumbo jumbo(Picture 1), after a couple reboots same thing continued to happen, a few times it flickered on and off from that and sometimes it just took a minute to get to it. From my own research this seems to be a GPU problem but I don't really get it how only the BENQ(my main monitor) is getting these errors but my 2nd monitor is fine, when I get these "artifacts" I can still use my second monitor for everything.

AMD driver re-installed.
I've swapped out my GPU's PCIe cables to the ones I didn't use before.
So the things I've done: Swapped the DVI-D ports for my monitors, still BENQ is acting up.
Checked for my desk for poor cable placement(stuck under the table, etc), still BENQ is acting up.
Tried a HDMI cable, which helped to a certain extent, It doesn't instantly boot into the "artifacts" screen but then the "artifact screen" comes out of random. For example picture 2 was after an ALT-TAB out of GTA 5. Also now with the HDMI cable majority of the time when I go into chrome this happens.
So I'm kind of at a loss of is it a GPU or monitor issue. I also posted this in the monitor sub-forum.

PC specs just incase:
I will be getting a 1070 soon but it will really blow if this is a monitor issue.

Windows 10 - PS. the CPU and GPU had higher clocks but I took them down just to test if I can figure out if my GPU is mental.

Hard to say, can you test the benq with any other setup or possible a console. anything with video output to test it outside that one computer? that would near immediately solve which one is the issue, if the second monitor is fine i say its a monitor issue but can you hook up the second monitor via hdmi or however you had your benq setup, if it runs fine that way i say its monitor. if both things work then ive no clue, they dont like each other anymore? lol. but really it should be one or the other, what is the second monitors resolution?

Just to rule out the obvious, have you tried a clean DDU driver install?

Does booting into safe mode fix it?

@InverseTundra Sadly I don't have any means of testing each of them in a different setup. The 2nd monitor ran at 1600x900, while benq ran at 1080p. I had the setup for 2 years, the differing resolutions didn't become a problem once.

@brucethemoose I did the normal uninstall. Haven't booted with safe mode.

Now, since the warranty was over for the monitor. And I managed to talk to a guy that had a similar issue on the same monitor. He recommended that I get the power board looked at. So I decided to start the disassembly. This monitor also went to a warranty check once before(8 months ago or so), and those guys ripped the plastic back-panel off this, with what I can only imagine was a crowbar, half of the plastic pins that held the back panel together with the monitor were close to broken. These Benq's are built utterly poorly, the metal housing that held the power board and the HDMI, DVI and VGA ports was held in place with tape... You'd think they'd use some type of screws or something but I guess no. So after I took it apart this is what the power board looked like, wonderful burnt spot and a couple of swollen capacitors:

Not uncommon way of throwing a monitor together and the issue in the image is generally what happens to monitors over time. Usually when a monitor "dies" it can be fixes by replacing capacitors or other replaceable components on main boards. Common for people to buy dead monitors and fix them for a few dollars and resell.

Should I try to fix it myself, I've soldered before but on some random hunk of crap. Capacitors should be a easy pull out and new ones in, but I'm not all that confident in this idea. And I have to find the correct capacitors.

The burn is a concern. If it were just the capacitors, yes it would be an easy fix. If you could just find a replacement board to throw in for cheap with some digging around if you don't want to just buy a new monitor. Buying extra parts may be wise if it's a common issue and you really like the monitor.

I've so far sent emails to 3 monitor repair places, hopefully on monday or tuesday, I would've heard something from them. With the 5 minutes of googling, I'm really going to have to go deep into the internets to find this board.

The burn is very worrying but Caps are cheap, could replace them and see how it goes, it does depend if anything else is damaged beyond simple repair and would need a new board, does anything else look damaged or affected aside from the caps and oddly placed burn mark.

When I took it apart, I only looked at the power board but as far as that goes, the burn and a few capacitors seemed to be the only problem.
