Hey everyone, I’m trying to figure out what’s causing my CS2 to suddenly crash, and I’m honestly running out of things to try.
I’ve had this PC for around 3 months and have been playing CS2 without any problems for the last 2–3 months. When I first built the PC, I did have an issue where CS2 crashed, and somehow the GPU driver got uninstalled/corrupted. I’m not sure what happened, but I fixed it then. After that, I had zero issues for months.
Now, CS2 suddenly crashes consistently after about 10–20 minutes of playing.
PC Specs
CPU: Ryzen 5 3500 (6 Cores)
RAM: 24GB DDR4 Corsair Vengeance — 1×8GB 2400MHz + 1×16GB 3200MHz
Motherboard: MSI B450M Pro-A II
GPU: MSI Armor OC RX 580 8GB
AMD Wraith Stock Cooler
SSD: WD Green 240GB NVMe M.2
HDD: Seagate Barracuda 2TB 7200 RPM
PSU: Cooler Master 550W
RAM
I originally had 24GB RAM:
8GB 2400MHz
16GB 3200MHz
Since they have different rated speeds, I manually matched the speed through BIOS. I've been using this setup for around 3 months without any problems.
I initially suspected the mixed RAM might be causing the crashes, so I removed the 8GB 2400MHz stick and tested CS2 with only the 16GB 3200MHz stick.
It still crashed after 10–20 minutes.
Things I've already tried
Verified CS2 game files through Steam
Closed all background applications and ran only CS2
Removed the 8GB 2400MHz RAM and tested with only the 16GB 3200MHz stick
Tried uninstalling the latest Windows update because the problem started after a Windows update last week
Tested CS2 after rolling back the Windows update — still crashed
CS2 graphics settings are already set to low
Valorant works completely fine and doesn't crash
The timing is what confuses me. Everything was working perfectly for months, and this suddenly started happening.
Could this be overheating?
I'm also wondering if CPU/GPU temperatures could be the issue.
The case is relatively small, although I have multiple fans installed for ventilation. I've never had overheating/crashing issues during the previous 3 months.
Could overheating suddenly become an issue even if the system was completely fine before?
I'm also hesitant to reinstall Windows because I've seen multiple Reddit posts where people said reinstalling didn't solve their CS2 crashes.
What should I check next?
I'd really appreciate suggestions on how to properly diagnose whether this is:
GPU/AMD driver related
RAM instability
CPU/GPU overheating
PSU issue
Windows issue
CS2 itself
Are there any specific stress tests, temperature monitoring tools, Event Viewer logs, BIOS settings, AMD driver checks, or other diagnostics I should try?
I'm especially interested in figuring out what is actually failing rather than just reinstalling everything and hoping it fixes it.
Thanks!
