Question GPU seems to disconnect from the PC but I still hear everything ?

[KennyRose]

I've been having this issue for a long time. While playing games, the game will freeze, it seems that the monitors say they aren't plugged in anymore, and I cannot fix it outside of restarting the entire PC. I had a 500 psu and I just bought a 750 and its still happening. I've cleaned the GPU and everything, I've seen elsewhere that someone else's GTX 980 was also doing this. But I'm unsure if a solution was found?

Doesn’t sound good for sure, I would try and lower the clocks of the GPU and see if it still happens then.

What are a 500 PSU and a 750 PSU? Just knowing wattages is like asking the mechanic for advice about your car and only identifying the size of the gas tank.

How can I go about lowering the clocks? Also, is that normal? Also I looked at MSI afterburner and its all blank now? That's never been like that its all 0 or blank in all spots.

Like a CX500 and the new one I just installed is a EVGA 750W GQ GOLD if that works. I don't know a whole lot about PSUs.

So I went into MSI Afterburner and took a look at the (Core Clock Mhz) setting and set it to -400 and everything seems to be running fairly well at the moment. I will keep you all updated.

So what I suspected is true, the GPU is just old and degraded, it can’t keep the original clocks anymore. I don’t think you have to lower it that much, try -10 for starters and decrease it by another 10s until it is stable. Test it with 3DMark Firestrike every time.

Day 2, I haven't changed it off -400 yet because I'd have to do a bit of experimenting to get it to work. But day 2 on -400 and still no issues whatsoever. Even left the game on and stream running on accident overnight and woke up to it still on. The issue might be truly resolved.
