My graphics card's ic just lit up in front of my face.

First, out of the blue, my pc wouldn't start, like at all. The hdd light would just blink once, and the pc would just die. No screens, nothing. Then I opened the side panel of the pc to see what was going on. Then I clicked the power button, and a bright burning yellow light just breathed once. Then i got a light to see what it was, and it was this. Now, miraculously the pc is running like nothing happened.

Hi Rafieshan, and welcome to TSG.

Judging from the silk-screened part designation on the printed circuit board and the appearance of the part, a capacitor, not any kind of integrated circuit (ic), burned up.

From your description of what transpired, I suspect the capacitor may have been used as a local filter capacitor across one of the video board's supply voltage inputs from the power supply. If this capacitor had initially failed with an internal short circuit, it could have drawn excessive current and started to overheat. The power supply's overcurrent protection may have shut down before the capacitor burned up. Doing this several times may have further damaged the capacitor until it did actually burn up before the supply could shut down.

The video board would appear to have normal operation if the capacitor failed and became an a open circuit. It is likely that any electrical noise on the power supply line is low enough to not require a bypass capacitor in your particular case. If video does become erratic, you may need to replace the capacitor.

Thank you for your reply.

Be happy that the failed capacitor did not cause any further damage. Keep using the computer.
