The computer fails to turn on.
Define 'on' as being in a state where the CPU and fans were active, or possibly having initiated a shutdown via Windows and left the device powered. At this stage, the exact situation isn't crucial, but knowing your steps is important to fix the issue. Every GPU manual advises removing it completely. My assessment: you likely damaged the hardware by working on a live circuit. The GPU power slots can draw up to 75 watts from the motherboard alone and short-circuiting through them could damage the board, motherboard, and power supply. You probably also damaged internal components, which is why the power button won’t work. My suggestion: avoid connecting any new parts to old ones and start fresh. If you still want to build PCs, consider using a fire extinguisher. What new PSU model has the label 'printer ink'? It’s likely not genuine ink—it probably comes from a failed capacitor. Capacitors use an electrolyte, which is unusual for everyday use. What brand and model was it? Where did you purchase it? This reminds me of a past incident where a customer had to create a new PCIe slot after modifying a motherboard to fit a 32-bit connection, only to have the system fail immediately when powered on.
The unusual red flash could indicate a faulty capacitor short or another type of fault. Using this part is dangerous—it can create intense heat and possibly ignite nearby components. It may also harm other parts that might still function when trying to power the system from the PSU. Please, do not attempt to operate this setup unless you are certain of what you're doing.
I demonstrated this to some tech-savvy friends, and it occasionally blinks blue. It isn't a brief issue.
You're thinking about getting a gift for Christmas and will take your PC to a repair shop. I'll keep you updated as more details come in.
