Hi, I have an Hd Radeon 7870, with my drivers up to date, and I've been having signal issues since I purchased my PC a year and a half ago.

My problem is the following, at random times my screen freezes for a second, the music stops and the signal is lost, then the screen turns black and then it recovers and a message says that amd software stopped working but it was recover appears on the screen.
Also, after some time playing a game (it doesn't matter wich one) the screen freezes the sound is lost and inmidiately the screen goes black, the PC still works, I can hear it working and if I turn it off and restart everything works fine, but this happens randomly some times is after five minutes of playing some times after an hour... Same as with the sudden losses of video, and is pretty weird because i have an HDMI switcher connected with a console and a TV reciever and this problem doesn't happen with them, well the TV reciever has lost the signal very few times but that isn't related to the PC issue.

Things I've tried:
-Connecting it without the HDMI switcher
-Two different HDMI switchers, one with power supply
-Different cables
-Different drivers (I have updated my drivers a couple of times since I purchased the PC)
-Different HDD ( I have an SSD now)
-Changed the motherboard

I haven't overclocked my system, but I have tried the OCTT test and the signal was completely loss.

I honestly don't have any idea of what I can do now, I've seen a couple of threads with problems like mine, but there is never a definitely solution, so I hope you people can help me.
Thanks.

two things to look at.

1. cooling... what are the temps for your processor and video card when it does this?

2. power supply. What make / model are you using?

Hi
1: When I do the GPU test it's very high, it reaches 60ºC, at max settings
2: Antec VP550P Basiq 550W

Thanks for helping me

Specifications are minimum of a 500 watt power supply. Honestly, running the complete minimum is never the answer. If at all possible, replace your psu. That very well could be the issue. Also, you didn't mention which os you're running, amount of ram, etc. Having a complete system spec will make it much easier to diagnose ( processor, ram, os, etc )

your temps are fine (gpu's typicality run much hotter then cpu's)

your power supply is near the minimum, but right now i wouldnt be looking at that as the #1 issue, as typicaly when you have a power supply that is underpowered, you would be seeing lockups and windows crashing.

for the powersupply, i would want to know, motherboard, proc, number of hdds, number of fans, water cooling etc..


right now i would be looking at the driver.try uninstalling the driver using this guide (i know its a bit dated, but it still applies) https://forums.geforce.com/default/...-ensure-your-drivers-are-installed-properly-/

then reinstall using the current driver.

If you still have issues again, uninstall using the steps above and either try a older version, or go for a custom driver from http://www.omegadrivers.net/


another thing could be your hard drive and the drivers being installed on a bad sector. try installing to a different drive or partition

The only nice thing about your situation is that the computer doesn't completely crash - that almost rules out hardware entirely (video card is still a possible culprit).

If the driver is crashing, then I would suggest looking for alternates. You said you are running the latest - what is the version number you have now?

It sounds like a problem with the GPU, TBH. Maybe a minor defect in your particular unit. I would consider a warranty replacement.

The power supply is fine--nothing wrong there. The wattage ratings that a GPU maker cites is usually way above what you actually need. The amps your PSU can deliver is a much better figure to look at, because there are some "500W" PSUs with 12V rails that are weaker than what you'd find in a quality 300W PSU, and it is because of the former that official GPU PSU reqs are so overinflated.

I would even call the video card the probable culprit. I would RMA it.
