PC not booting

[Wauter]

Hi, I have a custom built nas, but after a power loss it doesn’t boot anymore, when I connect it up to vga I see a screen that displays an error, but all the letters are scrambled and I can’t read it.

If your system was reading or writing to your HDD or SSD, the power outage could´ve caused a fatal error in the HDD or SSD. I would recommend taking it into a BestBuy or something

Im in the netherlands so yeah. And I would like to fix it myself. The system has an 32gb usb as boot drive, 2 160gb hard drives for storage, and a 64gb ssd for cache

First thing to do - take the CMOS battery out (google it if you don't know what to look for on MB).

To be safe unplug it, press the power button 2-3 times (ofc it won't start or anything but we want to discharge caps), remove CMOS battery, wait 10min, replace the battery (get a new one if current one is old/low voltage - if you know/can test it), plug it in, report if anything changed.

Didn’t help, waited 20 minutes, when I needed to press f1 for boot the screen turned completely off, while the fans where still spinning and he system was powered on
