Whats wrong with my pc？
My computer had trouble starting up today. It took four attempts to finally boot into the system. On one failed attempt, just as it was about to enter the OS, the screen showed garbled artifacts and then the PC shut down automatically.
After it finally booted successfully, it ran for a short while and then froze again. I forced a restart, and this time I got a black screen error**（**IRQL_NOT_LESS_OR_EQUAL). After that, my graphics card stopped working completely:
· The GPU fan does not spin at all.
· There is no display on the screen — the monitor stays black.
I have already tried reseating the graphics card and cleaning its gold contacts with an eraser, but the issue remains. Currently, the computer shows no display, and the graphics card appears to be not receiving power or dead.
