I have a gtx 1660 super which turns off in the middle of doing something. I don’t get any output to my monitor and even restarting doesn’t solve the problem. It is quite random and very frustrating to say the least. The only solution I have now is to wait for an hour or so and restart - I’ll get display output if I’m lucky.
When the gpu stops, the motherboard debug led doesn’t light up. The led lights up only when I restart the PC.
Is there any way to check if the issue lies with the motherboard or the gpu without using another graphics card ?
(I dont have integrated graphics either, because I have an i5 10400f)
My motherboard is - MSI B460 M Pro VDH wifi
EDIT: Got a 4 month used rx 6600 for ~ $120 and now this problem no longer happens. it’s not a substantial upgrade from my 1660 Super but an upgrade nonetheless.
If I understand correctly, you’re getting a sudden loss of signal to the monitor but the rest of your system remains powered on (fans, lights, maybe capslock is also still responsive).
An abrupt full system shutdown is often the result of a thermal or power problem. If a component (CPU, GPU) overheats or the power supply is asked to deliver more power than it is able to, everything will cut out.
Others are citing thermal issues and there is merit in checking your temperatures but that is not likely to be the case here because of what I just listed. I would also add that an overheated GPU will be able to power on again within minutes, not an hour, after the shutdown event.
Symptoms point to a likely defective GPU. The most common point of failure is the VRAM. You can find and run Nvidia MATS/MODS diagnostic software to test the card’s memory and confirm whether or not that is what’s happening.
Ultimately, troubleshooting is a matter of isolating problems and the best way to isolate a hardware issue is by substituting in supplemental hardware.
If you’re able to replicate the issue fairly quickly (e.g by running a benchmark program to force the card to drop out), you might start with the power supply since it’s usually the cheaper component to replace.
I got a different GPU (an rx 6600) and it works fine. Never had the display blacking out problem even once.
If it’s a problem with the VRAM, will my 1660 super be fixable ? I would like to give it to my younger sibling, if I can get it fixed.
Yes, though whether or not it’s economical to do so will depend on local economics where you are.
If you bought the card new yourself, it likely would have come with at least a 3 year warranty.
