[SOLVED] Bios and driver updates effecting gaming restart issue

[matty_m]

I'm hoping someone can offer some advice to help me narrow down my problem. I can't figure out if my issue is a hardware fault specifically, but updating the bios and drivers for my motherboard seems to impact the issue so I'm thinking that may be the culprit.

For several weeks I've had a problem of my PC restarting suddenly sometimes when gaming. The main points:

• PC components are several months old. No issues before, but I don't have spare parts to try so I would need to buy parts to try replacing (warranty isn't a thing where I live).
• It definitely isn't temperature related, and HW Monitor doesn't show any power/other issues I can see (with my limited knowledge).
• No BSOD, nothing useful in windows events, effects multiple games.
• When I updated the BIOS firmware the problem went away for 2 weeks, then got progressively worse again.
• I updated the drivers for the motherboard today to the proper ones from MSI's website and it got worse.
• While tinkering I noticed windows reports my ram speed wrong. When I changed it manually in the BIOS it made the problem much worse, so I set it back to auto and it went back to kind of bad. Tried reseating RAM, no change.

Components are:

• MSI MAG B550M Mortar WIFI
• Ryzen7 3700X
• iGame RTX3070
• Adata Spectrix D60 16gb
• Gigabyte 650W PSU

I don't mind having to replace a part, but at this point I could be replacing part after part and not fixing the issue because I can't really be sure if it is the motherboard. I would be very grateful for any advice even if it helps me to rule out certain components.
Thanks in advance.

use msi afterburner and lower power limit there..say 80%
replacing your PSU with someting better quality would be your second option

Thanks, I'll give it a try and see how it goes. If it turns out the PSU is the problem is there a particular brand or wattage you recommend? I have looked at how much power my pc might be drawing but i'm far from proficient in understanding the details.
