If PC restarts and it's not PSU, RAM, or MOBO, what could it be?
PC enthusiast, perhaps new to this forum but I’ve been working on an upgrade plan where I aim to get quality hardware at reasonable prices. Here are the specifications I’m considering:
Motherboard: a320m-k → a520i ac
RAM: 24gb unknown → 32gb kingston fury
Power Supply: evga 450 → evga 600bq → sfx pro dagger 450
GPU: rx 5700xt sapphire pulse
CPU: ryzen 5 5600g
I’m trying to understand from which specs to the next I’ve shifted. I’ve run benchmarks, nothing unusual except occasional crashes during intense gaming or rendering tasks. For example, with Warzone, I consistently hit a crash without any restarts—only a full PC reboot, black screen, then Windows login.
All the latest components are brand new, including storage drives, and no file errors have been reported. The Windows Event Log shows kernel activity only, with critical errors causing an unexpected shutdown.
The GPU and CPU were tested individually; the CPU is stable, but the GPU doesn’t show any failure signs despite heavy rendering. Drivers are up to date, and the system has been formatted and reinstalled cleanly. I’ve also ruled out power issues or outlet problems, though power surges were considered.
I recently tried playing Minecraft Server Mode 2 and encountered a crash during a specific scene, which prevented me from finishing the game. Now I’m able to play again, but it’s still confusing. I haven’t done VRAM testing, but I don’t think that’s the issue. Everything seems clean, the graphics card is handling stress well (75%), CPU at 65°C.
I’ve searched many forums and sites for similar problems, but no solutions have been found. Now I’m hoping someone with experience can help me resolve this.
Welcome to the forums, newcomer!
MOBO: a320m-k -> a520i ac
Is this your motherboard? If yes, what BIOS version are you using for your newer board?
PSU: evga 450 -> evga 600bq -> sfx pro dagger 450
GPU: rx 5700xt sapphire pulse
Source (borrowed, not purchased) a well-built 750W unit and check if the problem continues.
That's correct, the BIOS version is A520I AC F18. The driver version provided was the one automatically offered by Windows as an option. I'll check what I can do about it. It was tested on a 750W build and didn't show any reboot issues, but it's hard to be sure it will solve the problems. Switching from a 650W PSU to a 750W one is quite a jump, and the issues still seem to remain. The GPU monitoring shows it can draw up to 225W, which matches what the stress bench claims it should handle.
Just sharing this too, an example of emphasizing them well, no stutter or restart needed but playing something achieves that. It really captures the driver vibe, though I'm not sure what else I'm missing from switching the motherboard to restarting Windows and keeping the GPU and CPU drivers in good shape.
The issue remains unresolved. I've replaced the CPU and focused on the GPU, but no adjustments in BIOS have helped. I'm testing drivers with DDU now, though I haven't found a reliable 750W option as before. Any advice or alternatives would be appreciated.
psu is on a weaker side. sapphire suggests a high-quality psu with at least 650 watts.
pulse rx 5700 xt 8g ddrd6 supports up to 1925 mhz, 8gb/256 bit gddr6, 14 gbps effective.

the card’s total power is around 241 watts; including other parts you’re looking at roughly 350 watts or more. basically, you just need to power the psu after it’s turned off.
what is your maximum budget?
