Sacramento Power Supply Repair Service

It’s so easy to take On switches for granted. We live in an age where you can just plonk yourself down in front of your laptop, hit the go button, and wait for the colorful screeny goodness to arrive. Unless you own one of these, no hand cranking is required. Unless you own one of these, no frantic bicycle pedaling is needed to get your morning social media fix. 

(If you do own one of those ^^^, please drop us a line or drop into our Sacramento store; we want to meet you.)

But what actually happens when you hit that On switch? Quite a lot as a matter of fact, and it all revolves around this mysterious chunk of technology known as a power supply. This wonderful component converts alternating current (AC) into direct current (DC) which allows you to turn on your computer to do important computer things (like listening to Australian rock music band, AC/DC.) 

Power supplies and PC power supply replacement

Crucially, your computer’s power supply provides a precise amount of current to your computer’s components, keeping them operating as intended while protecting each component from damaging electrical spikes. 

But sometimes things go wrong, and when they do it’s important to perform a computer power supply repair quickly before other components in your computer also become damaged. PC power supply replacement requires getting up close and personal with sufficient electrical charge to cause significant harm. That’s why we recommend you have Nerds On Call perform a computer power supply repair for you. We’re located in Sacramento and have been helping locals fix their computers for close to two decades.

Key signs that you may need computer power supply repair

A lot is going on inside a power supply. It steps 110 volts down to a workable DC current, which means it generates heat. It’s equipped with a fan to manage that heat, but fans wear out. A host of variables — age, room ventilation, presence of dust and fur, and prolonged heavy use — all factor into how quickly you may require PC power supply repair. 

Here are the classic signs that your computer may soon require a computer power supply repair. If you do notice any of these signs, give us a call. A capable mobile repair nerd can come to you, wherever you are in Sacramento.

1. Odd sounds

No two failing power supplies sound alike. But if you hear any kind of metallic scraping or grinding sounds, a computer power supply repair may be necessary.

2. Nasty burning and melting smells

Smell burning or melted plastic? That’s never good! Your best response is to switch off your computer immediately and have a technician assess your computer to determine whether a PC power supply replacement is necessary. 

3. Frequent crashing or failure to turn on

Power fluctuations are a common cause of computer crashes. If your computer won’t turn on at all, there’s a good chance no power is reaching your computer. In both cases, one of the most likely solutions will be computer power supply repair.

Questions nerds often hear about Sacramento Power Supply Repair

Is it safe to do my own computer power supply repair?

Only if you’re deeply familiar with working with 110 volts. It’s important to remember that your computer’s power supply has a direct connection to mains power — which pushes enough current to seriously hurt you if it isn’t done right. We strongly recommend you work with a certified tech for any PC power supply repair.

I upgraded my PC. Do I need a new power supply if my old one worked perfectly?

This depends on how much heat your new computer will produce. A powerful processor is going to produce more heat than a less powerful processor, and you may need enhanced heat management.
