XFX 6950 Monitor losing signal.

post #1 of 8
Thread Starter 
So my monitor goes into standby and I think it's the GPU fan that spins up when it happens. I've checked power cords a few times, reseated the card multiple times, blew dust-off in the mobo slot, only ran the PC with my Asus 6950 with no problems, and I have a brand new PSU(1000 watt 80+ gold). Memtest has been running for 8 hours with no errors. Prime95 can run 24/7 and not error.

Oddly enough, the POST will give me the long beep and three short beeps indicating GPU problems. Unplugging the PSU and then powering on the PC allows it to boot just fine. The POST beeps have only happened twice but the monitor standby has happened a dozen times now and it's happening a lot more frequently now during normal usage, and not gaming.

The GPU isn't OC'ed and the temps are fine. It idles at 37C and hits 59ish at full load. At this point I'm guessing it's just a defective card. I've done driver reinstalls and even updated to the newest version from the XFX site to no avail. I don't get BSOD's and the PC keeps running I think since music will keep playing normally when this happens.

What do you guys think? I've also tried a different monitor and the same thing happens. Any feedback is appreciated. I just submitted a ticket to XFX, yay for lifetime warranty! It'd be nice to get a 7950 replacement but I'm not holding my breathe.

You've done pretty much everything you can; I'd agree with you in saying it's probably a defective card.
Good luck with XFXs RMA process, I hear they aren't the best. redface.gif

Well I'm not gaming now and have a good ole 9800 to get me by. I've had to deal with XFX before. They sent me a 6950 for a defective 5870. Maybe I'll luck out again and get a 7970. /sarcasm

I'd settle for a 7950. Either way, thanks for the feedback. Had memtest run all last night again with not one problem. I'll try one more set of drivers but that's it.

Yesterday the monitor lost signal twice in a very short period of time. I usually have a VMWare running most of the time for work. I updated the driver to the newest version from the XFX site after running DriverSweeper. Played two movies on my TV through Windows Media Player and have had my VM running on my monitor with no problems. Keeping my fingers crossed.

I had the PC overclocked to 4.0 GHz so maybe that was causing the problem. For some reason after booting the PC after the all night memtest I had a POST OC error. Restored to defaults and am running my RAM at 1333. Perhaps the OC caused the problem but it's weird that didn't happen with the ASUS card.

Going to have it run all day and see what happens.

Well I took my side panel off my HAF X and bumped the video card to see if that did anything and sure enough the screen went out. At this point I'm thinking the two 6-pin connectors may be defective on the video card, or loose somehow. The same thing doesn't happen with my ASUS card. Could that potentially be causing the problem?

Inspecting the copper contacts on the card I noticed one wasn't fully extended out along the pcb, where the copper thins out to make contact to the PCIE header. Possibly that?

Well I still am running smoothly. I even moved my tower to vacuum today and no signal loss. Later on tonight I'll wiggle the power cables a tiny bit and see if the same thing happens.

XFX gave me an RMA # today after a bunch of runaround messaging. Their phone support was not available. After reading about how slow their turnaround times seem to be I'm hoping that the copper contacts were just dirty. Prior to the last install of the card I wiped all contacts with 90% iso with a coffee filter and there was some residue that came off.

Sending it in would be a nightmare since my PC is also a media center with tons of movies my daughter watches. Keeping my fingers crossed about fiddling with it later!
