Rebooting loop (5 seconds), no BIOS screen.

[Zeeg]

Hi everyone,

First of all, I read about ten threads about this issue before posting here for help, so I'll share all the knowledge I've with you to troubleshoot my issue.

What's up with my computer?

So, my computer is not booting at all, meaning, the PSU starts, the mobo starts (well, it seems at least), and after 5 seconds, everything stops, and restarts by itself.

What have I tried yet?

1) My first guess was a faulty PSU, so I just switched to my other, much more powerful PSU to check if that solves the problem.

That obviously didn't work, nothing changed.

2) I then thought it could be a faulty RAM stick (make those sticks burn in hell!) so I tried with one, then the other, then none.

Still nothing.

3) Well, maybe it's the BIOS that's faulty. (a BIOS-hazard? Nevermind...)

Here's the tricky part for me, since my mobo seems not to have any clear CMOS switch, and only a two pins JBAT1. So, I removed the CMOS battery and switched sides for 5 seconds just as MSI recommends to do.

The problem is still running. *Sigh*

4) What about a faulty SSD?

That seems weird since it can't even reach BIOS, but just to be sure, I unplugged my SSD from PSU & SATA.

And nothing worked again.

I've now multiple choices to troubleshoot this:

- The mobo is fried, and I'm fucked since I've no other CPU to test it for this socket.
- The CPU burned in hell, and I'm fucked aswell, since I've no other mobo for that socket.
- I did the CMOS clear part wrong, and I would appreciate some feedback about this part.
- Insert guess here. :-/

Thanks everyone

Hi, If starting the board, only CPU and CPU fan installed, both 24 and 4/8 pin power cables connected, front wires disconnected (use a screwdriver for shorting the 2 pins) is it the same (same restarts)?

I just tried with only mobo, CPU, CPU fan, no RAM stick, no GPU, not even SSD nor HDD, and it's still the same, so let's face it, the mobo or the CPU is fried...

The mobo should have a LED that turns on when power is connected to it, is it lit?

 

[Zeeg]

My mobo has a power button that lights up directly when the PSU is plugged in, and when I turned the power on by pressing the power button on the mobo (not the front panel), six LEDs lights up, but I think that doesn't mean my mobo isn't fried.

Don't you have a friend or an acquaintance who can borrow you a motherboard with the same socket?

 

[alexoiu]

Either the board, or the CPU. Have you OC-ed?
If under warranty, Try RMA-ing them both.

 

[Zeeg]

I didn't OC-ed at all, I didn't even changed any BIOS setting nor did any hard benchmark with OCCT.

I'm going to borrow a MB and a CPU to a friend to test mine and now what's wrong, thanks for help!

You're welcome.
