I've been upgrading my PC for gaming over the years, and while it still performs decently, I'm encountering a frustrating issue. I recently replaced an old GTX 1060 (which had seen better days from being used for crypto mining) and my 600W PSU with a new RX7600 and a 650W MSI Bronze-certified PSU. Despite this upgrade, my computer randomly crashes during games, showing a black screen with no audio, and it doesn't restart automatically.
The crashes seem to happen quickly, like within 1-2 minutes into more demanding games (I tried Path of Exile 2), while I've had some luck running Sea of Thieves longer without issues.
Strangely, after reseating the RAM, the crashing improved slightly – now, I'm getting around 5-6 minutes of playtime before it crashes with Path of Exile. The frame rates stay stable, and there's no overheating; my GPU stays around 35°C while idle and climbs to about 50-55°C when gaming, with my CPU being similarly cool.
I've checked the PSU connections, swapped cables, and even ran stress tests like FurMark and a memory test which came back clear. When idle, the PC runs perfectly fine without any crashes.
Here are my specs:
- CPU: i7-4770k
- GPU: RX7600
- PSU: MSI 650W Bronze-certified
- Motherboard: MSI H81M-E33
- RAM: 2x8GB DDR3
- Storage: 1TB SSD
Do you think there's a chance the GPU or PSU might be faulty? I can't return the GPU, but I could still exchange the PSU if needed. Any advice would be greatly appreciated, and I'm aware that my setup has some bottlenecking; upgrading other parts is on my to-do list later.

Check if your memory is set to the XMP profile in the BIOS; if it is, try disabling it and setting the speeds to stock. Sometimes, the memory can be unstable at the overclocked settings. You could also test each RAM stick individually to see if one might be causing stability issues.
Have you tried running memtest86 on your RAM? It can reveal hidden issues that the Windows memory diagnostic might miss. It’s worth checking to rule out any memory problems.
I just did a memory test with Windows and memtest86, and both came back clear. Seems like my RAM is okay.

I haven't checked the XMP profile yet, but I will if the previous suggestions don’t resolve it. It’s weird because memtest86 didn’t show anything wrong.
