Something has died

[Howling TerrorOutOfOffice]

My system has been running fine up until last night when it shut down (nothing intensive running ).
Tried to restart and could hear fans running and nothing on the monitor.
Had to unplug after a min or so.
Wouldn't boot. Nothing.

Opened case and switched on the power supply. The f bios led on the board briefly lit and then goes bright, then immediately out. If I unplug the power and wait 10secs or so, then plug in and switch on the PSU, the f bios led does it's thing again.

I started removing peripherals like USB ports and the ssds etc.
Then I removed the graphics card tried it and still nothing. I put it back and tried it again...nothing.
As I was tightening the screw the fans whirred into life. :o No monitor connected so no idea if it made it into bios. It hasn't booted since, and I've tried everything bar removing the 4 memory sticks.
Used another PSU and it's no different.

Gigabyte X99 UD4
Intel i7



Also posted this on the gigabyte forum and searched to no avail.

Cheers

[edit] removed memory and still the same.

Sounds like either screwed motherboard or cpu.

I say this as there were no error beeps when powered up without ram.

[Howling TerrorOutOfOffice]

It does look like it. Anything else I could do? Any simple way to see which bit has died before I start guessing and probably wasting £s

Try the cpu in another motherboard.

[Howling TerrorOutOfOffice]

That's tricky...old mobo is a different socket.

I was hoping the fbios led doing it's brief flashing thing would help me more.

Is there any sequence to the flashing?

[Howling TerrorOutOfOffice]

No sequence as such. It lights up then goes very bright all within a second or so.

Well thats not much use.

Unless you have the means to test parts in another system, it's going to be a "Best Guess" situ.

[Howling TerrorOutOfOffice]

Thanks for trying Mr C.

This is my first boot on the replacement board.....I guessed correctly.
I also bent a pin on the cpu socket, but a good furtle with a plastic toothpick and voila, a miracle...Phew!

Then I connect mem and SSds and vga....all good until it comes to a wi-fi card...goes into a re-boot loop as mentioned many times on the Gigabyte motherboard forum. I unplug card and here we are.

Temp readings appear ok. CPU 23 and System 28.

Oh...the f bios led. It does the same thing on this board too....then it boots.

Currently waiting for some weird OS issues or maybe win8.1 hasn't sussed the new board yet.
