Does you PC POST?
If no, does it spits error messages (or even mobo beeps)? If so you can figure out what's going on with the mobo manual, but it's probably a bad news for your PC.
If it POST, go to the BIOS and look what hardware you can see. Do you see your system disk and / or your PS3 disk?
If no disk appear at all, maybe you fried the SATA controller. In that case, you can probably boot a disk from USB to salvage your data.
If the disks appear, try and boot them. If it doesn't work, either the disk died or you just need to re-install your OS.
Always advocating for that but Aeon Desktop (immutable OpenSUSE) has been great for me: rock solid base system, latest Gnome desktop, all the apps in Flatpak. Distrobox for all the terminal applications needs works better for me than the toolbox on systems like Silverblue. Give it a try!
Oh right, the candlestick is the name given to a type of "error bar" chart in trading. When a pump and dump scheme happens, it typically draws a big big candlestick on charts.
Here's how I would troubleshoot that:

Let us know how it is going! Good luck!
