Lightning storm and PC won't begin.
Lightning storm and PC won't begin.
Last night experienced intense rain and a thunderstorm in my neighborhood (from 12:50 am to 01:50 am, with 7000 lightning strikes over a 40 sqkm area). It’s possible a lightning pole near my home struck. My PC was okay yesterday. After plugging it back in today, when I switched it on, the motherboard tripped. Now the PC won’t start at all, though the power supply unit and TV are functioning properly. I don’t have an UPS. I was planning to purchase an UPS and a GPU later. My PSU appears to be intact. I’m wondering what should I do now—maybe just the PSU is affected?
The RM1000x is a reliable power supply unit. It’s surprising how a surge can damage your entire PC, but it’s not unthinkable. (More research indicates the PSU’s quality doesn’t affect the outcome.) The simplest way to check is to switch to another power supply and see if your PC works. Some shops can assist with diagnosing issues like this. If needed, you could also test the voltage from the 12V pins using a voltmeter to confirm if the PSU is faulty. You’d need to connect two pins in the 24-pin cable, which is straightforward enough.
All systems are operational. The router is connected via Ethernet cable to the PC, and the monitor functions properly even after the MCB tripped. There is no indication of power being supplied to the PC when I press the power button.
Have you attempted turning the switch on the back of the power supply? If that fails, remove the CMOS battery for 5 minutes while the PSU is off.
I used the paperclip method But the fan in the Corsair RM1000X won<|pad|> a bit and only started once it got some pressure so I couldn’t confirm if the PSU was dead. It’s raining here, so I might go to the store to check another power supply. I think I’ll have to wait a while.
Start by backing up all your drives as the initial step. Be cautious when attempting to boot with a faulty PSU—it could worsen the issue, just like Doctor Nick warned. After turning off your PC, let it sit for a moment before pressing the power and reset buttons several times. During a surge at my home, I had to follow this process. From my personal experience, you might want to skip it; I discovered both my graphics card and PSU were faulty and were affecting each other, causing the PSU to fail again after replacing it.
