PC not loading, tried much, A2 error while booting

[trzasku]

I came back to my office and saw that even though I shut him down when I left my pc is running and the screen is  stuck on the bios loading screen at the code A2. I reset the PC but again it stopeed loading at A2. I tried to enter the BIOS by pressing DEL and but it seems that the keyboard is not working properly.

 

I tried:

• Using another SATA Port
• Using another Sata Cable
• Entering BIOS with SSD dissconected (It is stuck on A0 code and the keyboard is not working)
• Entering BIOS with SSD and Graphics Card dissconected (It is stuck on A0 code and the keyboard is not working)
• Entering BIOS with SSD and Graphics Card dissconected and with another PSU (It is stuck on A0 code and the keyboard is not working)
• Pressing reset CMOS button at all configurations that I mentioned above
• Entering second BIOS
• Entering BIOS with the button on the motherboard at all configurations I mentioned above.

Is there something more I can do? What does the A0 code mean? Do you think the problem is the SSD or mayby the motherboard? What would you do in my situation?

 

Motherboard: MSI Z77 MPower

SSD: Samsung 830 256GB

Processor: i7 3770K

Graphics Card: Asus GeForce GTX670 2048MB

PSU: Corsair RM650x

60°C isn't concerning, leaving it like that for an afternoon shouldn't hurt it.

I looked up your motherboard and it's manual. It says:

 

9A~A7,B4 - Onboard devices Initialize and Detect (USB/SATA/SCSI...)

 

You're stuck at A2 which falls in between 9A~A7 which means during the initialization process something didn't register correctly. Since you cannot remove components from the PCB (with ease) I'd start by unplugging every peripheral that isn't necessary. Speakers, Thumb Drives, Docking bays, everything except the cable going to the video card then see what happens.

 

No change?

 

Plug everything back in and try unplugging your SSD completely and turning the system back on. Since this is an error occurring during device initialization one of your components might have died (If it was your CPU you wouldn't even see the error codes on screen)

 

No change?

 

Try unplugging your graphics card from the motherboard (completely remove it) and plugging your monitor directly into the motherboard.

 

No change?

 

Plug it all back in and try replacing a RAM stick (or just removing them one at a time)

 

No change?

 

Have a spare PSU laying around? Try plugging it in and see if your situation improves.

 

No change?

 

Any chance you have a socket 1155 CPU laying around? You can try changing that out but I doubt it's the cause.

 

No change?

 

...your motherboard might very well be defective. I'd try a BIOS update if you could get in but if not you might have to buy a new board.

I tried everything on your great list but nothing helped  

 

When I dissconect the SSD there the bios is stuck at A2 and pressing F11/delete does nothing.
