Screen appears without notice during play but captures audio, and after restarting the VGA light turns on.
Hello, Your system (installed in 2020) includes an MSI B40 Tomahawk Max with a Ryzen 5 3600X, Zotac 1660s 6GB RAM, 16GB DDR4, 3200MHz, 256GB SSD, 1TB HDD, and a 550W cooler. It runs on a 144Hz 80+ Bronze PSU and has a 24-inch Benq monitor.
Problem: For about a month now, it boots fine and works well for regular tasks. However, when launching games like Valorant or Delta Force, the display fails to appear. I can still hear the audio, but after restarting, it doesn’t boot at all—showing a VGA LED instead. I had to power it off completely by pressing the CPU button or unplugging it from the wall. Once restored, it boots normally again, but the issue resurfaces when opening the game.
Interesting fact: I ran benchmark tools such as Furmark, Heaven, Cinebench, and OOCT multiple times, and none detected any problems.
What I’ve tried so far:
- Reseat the GPU
- Tested with another GPU
- Ran MemTest 1 stick at a time (even after passing RAM test)
- Updated DDU CMOS and BIOS
- Had my PSU checked at the official Cooler Master service center; voltages were stable under load
- Verified CPU for bent pins or other faults
- Replaced thermal paste about 7-8 months ago
Any suggestions or advice would be greatly appreciated. Thank you.
