Help! My PC Won't Turn On After Vacuuming

Asked by TechSavvyCat22
I recently had my mother vacuum underneath my desk, and now my computer won't turn on at all. There's no power, no LED lights, and no sound coming from it. I've already replaced the motherboard because I thought that might be the problem. I tried booting it with a screwdriver once, and it actually started but went into sleep mode. Now, when I try to boot it again, it's completely dead. I've already replaced the power supply because the old one wasn't responding to the paperclip method. I've also tried taking out one stick of RAM, swapped the CMOS battery, and nothing seems to work. I really need some help here, so if anyone has any suggestions or questions, please let me know!

First thing Iโ€™d check is your power outlet. Have you tried plugging in a lamp or something else to see if it works? Sometimes, a vacuum might trip the breaker, which would explain the power loss. Itโ€™s frustrating, but itโ€™s an easy fix if thatโ€™s the case!

JohnTheFixer: Yeah, Iโ€™ve had that happen too! Those vacuums really can draw a lot of power and trip the circuit.

Also, if you have a power strip, double-check the switch on it as well. I once spent an hour troubleshooting just because I forgot to flip the switch on my power strip!

Have you considered the possibility that static from the vacuum couldโ€™ve affected a component? It's rare, but itโ€™s worth thinking about if everything else checks out.

Just to cover all bases, did you check if the computerโ€™s power cord is fully inserted? Itโ€™s a simple thing but can often be the culprit. Iโ€™ve had that more times than I can count!

Make sure everything is plugged in correctly and that your PSU switch is on. Itโ€™s crazy but sometimes just a minor oversight can lead to big headaches. Also, you might want to try a different outlet to see if that helps.

Donโ€™t forget to check the switch on the back of your PSU. It's easy to accidentally bump it, especially when you're cleaning around there. Just make sure it's on!
