Help my pc isn't turning on
Yesterday evening I disconnected a GPU risers cable from the motherboard while it was powered on. Then I noticed a spark coming from the motherboard, and the computer shut down automatically. After that, smoke appeared, and now when I turn it on, the PC doesn’t receive power.
Whichever component the spark and smoke originated from. It's possible several parts were affected. Purchasing online gives you the chance to return items if a replacement doesn't work, but you must act swiftly so you can try different fixes. If you have a friend with a PC, you might bring the GPU over and check its performance there. Motherboard and power supply units are substantial projects—best not leave them to someone else.
If your CPU includes built-in graphics, consider removing the GPU and connecting the monitor directly to the motherboard. If it functions, the problem likely lies with the GPU. If a spark appeared from the GPU, it probably isn't completely damaged. It's more likely your motherboard is faulty, though it's still possible the power supply unit has an issue. If the PSU reacted negatively, it might have overreacted and could have caused damage internally. Avoid opening the PSU—it poses serious risks even when unplugged!
I hope it doesn’t cost too much to repair, but next time—you should probably unplug the PC first! USB is mainly for connecting and disconnecting while the device is on (other uses are mostly for business purposes).
