Can a high amperage PSU kill my mobo?

I own a Lenovo K220 from 2008

It came with these

Intel® Core 2 Duo Processor E7400,
2GB,
500GB 7200RPM S-ATA HDD,
no diskette drive,
PCI/PCIe Tower (4x4),
Intel Graphics Media Accelerator 4500,
16x Max DVD-RW,
10/100 Ethernet,
DOS License
Mobo maker and model is unavailable. Not even cpuz could find it.

Later in I installed another 2 GB RAM and a Geforce 210 and it ran just fine.

Recently my PSU died according to a local service center so I got a Corsair VS550 because I want to upgrade my rig later on and keep the same PSU.

Here are ever output details of the PSU that came with the machine.

Model: DPS-280FB G (max 280 W)
+12V: 18A
-12V: 0.3A
+3.3V: 16.7A
+5V: 16A
+5VSB: 2.5A

The VS550 has

+12V: 42A
-12V: 0.3A
+3.3V: 18A
+5V: 18A
+5VSB: 2.5A

My question is, will the extra amperage harm my mobo/CPU/HDD/ODD?

I plugged it into my mobo and everything but it stayed pretty dead even after flipping the switch.

I don't know if I've killed the mobo by doing so but I need to know for sure.

How to get around CKAuthenticator on my school's chrombooks?

My school issued all the students lenovo chromebooks, which is great and all and i'm really happy about it, the only thing is that they put a software on them called CKAuthenticator that prevents us from going on websites like facebook or twitter ad blocks out a lot of youtube.
for the first few months, we could log in to our own google accounts instead of using the ones the school provided for us, that worked to let us passed the block, but now the tech department has made it so we need to use our school google logins. We also can't use a VPN or proxy because the application is installed directly to the browser and it doesn't go through the Wi-Fi. I'm wondering if there's any way to get rid of content keeper without switching to personal accountsor using a proxy/vpn.
I have a picture of the extension description.

Added (1). I know that I probably shouldn't be doing this, but let's ignore that. I'm pretty sure that I won't get caught, considering that there are thousands of kids in the district. Besides, we bought the chromebooks from the district, so they're technically ours.
I know some kids were able to enter dev mode by some unconventional method, but I haven't been able to figure that out, considering that the school also has that blocked. Any workaround would be useful.
Thanks. How to get around CKAuthenticator on my school s chrombooks - 1

Computer flashed a bluescreen and shut off, what's wrong?

I was watching a video, when suddenly a blue screen with white text appeared for a second, then shut down the computer. The computer works fine, I'm just scared it'll happen again.
