Open | Hardware PC stopped displaying anything
Hi everyone,
Im having a issue with my gaming PC and would really appreciate some help.
PC specs:
Motherboard: ASRock B550 Pro4
CPU: AMD Ryzen 7 5700X
GPU: NVIDIA GeForce RTX 5060 Ti
RAM: 2x 16GB G.Skill DDR4-3200
OS: Windows 11
PC age: About 1 year
The problem:
5 days ago I had a random Bluescreen with the error code SYSTEM_SERVICE_EXCEPTION (0x3B). I turned the PC off, my monitors didnt receive a signal at first but after some time it was back to normal and nothing happened ever since.
Today after updating my NVIDIA graphics driver I experienced three Bluescreens while gaming. The last error code included:
KERNEL_MODE_HEAP_CORRUPTION (0x13A)
After the crash, my PC stopped displaying anything. BIOS booted up after a few restarts but then shut down again and since then the monitors have no signal. The fans spin, including the GPU fans, but the monitor still says no Signal and my keyboard doesnt light up either.
The CPU and DRAM debug LEDs on the motherboard turn red immediately when I press the power button and stay lit
What Ive tried so far:
Tested both RAM sticks individually in slot A2 and other slots
Reseated the 24 pin motherboard power connector
Reseated the 8 pin CPU power connector
Cleared CMOS (I believe?) using the CLRCMOS1 jumper with the PC unplugged
Waited several minutes after starting the PC
None of these steps fixed the problem. The CPU and DRAM LEDs still stay red and I still get no display.
The PC had been working for about a year, and I havent changed any hardware. The only recent change was the NVIDIA driver update.
I believe I might have cleared CMOS, I did it as instructed but I dont know if it resetted, since I still didnt have a display signal! Also Im not very experienced in Pc building and all that so any tips, suggestions and help I would really appreciate it
