Question I cleaned my computer and now it's slower

[BiasGamer2]

Sorry if this is the wrong area to ask but I'm notsure whats causing the problem. I cleaned my computer with a compressed air Duster and a vacuum to get rid of the dust and now when I try to play games like Nioh the it will stop working immediately and and other games just run much slower than normal. I used a regualr vacuum but I didn't touch anything it, just sucked up some dust in the computer.

Update your post to include full system hardware specs and OS information.

Include PSU: make model, wattage, age, condition?

The vacuum could have done two things:

At best, just pulled something loose. At worse caused an electrostatic discharge that fried a component.

Double check by sight and feel that all cables, connectors, cards, RAM, and jumpers are fully and firmly in place.

Use a bright flashlight to inspect everywhere for signs of damage.

Use Task Manager and Resource Monitor to check system performance.
