Urgent, need help! Mobo, cpu issue?

[MarcusLauk]

Hello, i have issues with my pc. The screen just went black and it tried to reboot. I am greeted to constant bootloops and the motherboard error a2. I have reseated all my cables and i have tested my ssd on another computer and it still works. I am even using a different psu to see if it was the issue, but still no fix. I have also tried moving my ram sticks around to no result. 

 

My specs are:

Intel core i7 3770k

Z77 msi mpower mobo

16gb dominator platinum 

Gtx 970 strix

The A2 code means it's having trouble detecting or reading drives. Do you have multiple drives connected?

Have you just built it? It usually happens when you've got multiple internal drives connected to the PC and you haven't got an OS installed so the motherboard freaks out.

Have you tried other SATA cables? Your current hard drive data cables might be shot too. (It is possible)

Hope this helped

Alright. Seems as if it's not too many drives so you should be fine on the drive subject.. 

If it fixes your problem, let me know.

I would unplug the HDD, so your only option for booting is the SSD. That way you can make sure that your mobo is not trying to boot to the HDD. What is your drive boot order?

Just tried different cable and different port. Still stuck.

I am only using the ssd now, I'm not sure about the boot order rn.

That's really strange. Sometimes things as simple as things plugged into your USB port can disturb the BIOS during startup, especially label printers and scanners.

Is anything plugged into your USB ports? I assume not, but it doesn't hurt to try

Alright, I would just make sure that the SSD is #1 in the boot order when you plug back in the HDD.

The only usb device plugged in is my keyboard at the moment, i will try booting with it unplugged.

Is your bios up to date?

Okay. I don't think a keyboard would disrupt the BIOS but computers are unpredictable

Also is your PC recently built or was it built over a year ago?

3-4 years old and i just got met with d7 error. It sometimes keeps randomly shutting on and off before getting to the boot error.

I know this issue, the A2 then D7 error. Most of the cases I've seen are involving the 3770k.

Try clearing the CMOS.

There should be a button on the back of the motherboard, and press it.

There's also this handy page too with the same mobo, CPU and the same problem as you too: https://forum-en.msi.com/index.php?topic=168051.0

You can read along with that if you want

I read that this guy has some similar issues, I'm afraid my other psu have killed the sata bus, i have a ax860i from corsair. It got a self test button or Jumpstart. It shuts of only when the 24 pin is connected to the psu. It doesn't have to be connected to a pc at all.

Oh, that explains the A2 error then [as I mentioned previously, the a2 code means it cannot read or detect one or more drive(s)]

Yes, it seems like my original psu shorts out and instantly shuts when the 24 pin is connected, i can start every other circuit without it shutting off. I can audibly hear the fuse shut on and off. I think the 24 pin cable is the culprit since it shorts the psu without being connected to a motherboard.

I agree. Try replacing the 24 pin cable and see if it actually is the issue though (it has to be, but you never know). 

Your PSU isn't the problem as you've verified it's working fine and from what you've said it seems to work without a fault.

I don't have a spare 24pin for my psu sadly, so it will be hard. My psu has a 10 year warranty, god knows what that covers. Im really not sure what to do at this point.

Try to find a cheap one on the Internet if you can. I'm pretty stuck too, so yeah
