I recently tried to clean out my PC because it was giving me a video output issue. My mom suggested vacuuming it and especially cleaning the fans. Unfortunately, I didn't have the best vacuum, so I ended up using a brush to spin the fans and clean the dust off the motherboard. Now, my PC is running at about 0.3 FPS, when normally it runs smoothly. I'm really worried that I might have done something wrong during the cleaning process. Can anyone help?

Just a heads up, you should really avoid using brushes on PCBs. Compressed air is the best for cleaning. Did you check if your fans have the correct diode setup? They often prevent issues when spun by hand in the wrong direction. Get some air blowing through there!
First off, check if your fans are actually spinning when your PC is on. If they're not, you might've jostled some connections. And don't worry too much about spinning the fans by hand; they're designed to handle that and usually wouldn't be damaged unless something was really wrong. Just make sure everything is plugged back in correctly!
Have you looked at the temperatures of your CPU and GPU? If they're too high, that might explain the performance drop. Sometimes it can indicate thermal throttling. A program like HWInfo64 could really help you check those temperatures!
Good call! Keep an eye on those temps for sure, and you might need to reapply thermal paste if they're too high.
Honestly, it’s likely that vacuuming didn’t hurt your PC. The slow performance could be due to other issues, maybe a failing hard drive or a GPU that's overheating. Do a quick virus scan too, as that might be draining your system resources!
If you want to really diagnose things, try downloading HD Sentinel Pro. It can help determine if your hard drive is failing. Keeping tabs on the SMART data is a great way to figure out if that’s causing your load times!

Yeah, it's super easy to accidentally disconnect something! Just double-check all your connections.
