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.
Could be thermal or electrical. Probably should redo the thermal paste. Make sure there is no corrosion on the card edge connector or in the motherboard connector's pin contacts. The latter is a subtle one too. If you see any contact discoloration it can be a poorly plated pin and can cause a bad connection as oxide does not conduct electrons. In hobby electronics and the cheap connectors I encounter, this happens a good bit and is super annoying because it is hard to spot and diagnose in many instances. Over the last 10 years the types of cheaply available connectors has grown in their sophistication and complexity. I would not be surprised if these same Chinese companies were now making motherboard connectors and parts. While it is nice to have cheap options, these cheap components are often at a bare bones type of production quality and process where some units will fail unlike the overbuilt and gold plated days of military spec components in the pre-90's era. Rusty connector pins can get scraped off enough to conduct for awhile after removing and reinserting. The effect may be different with different cards that scrape the pins in a slightly different way. However, just removing and reinserting the card causes the fiberglass to flex. The physical die and heatsink are anchored in different places and this tiny difference should move the heatsink compound ever so slightly, perhaps improving thermal contact. The same could be true of a dry solder joint where the flex causes better mechanical contact... or worse.
