New build not booting

pieplough · 24 Aug 2014 at 10:02

Hi guys,

After some suggestions regarding a build I'm helping a pal put together.

Basically the machine powers up, fans spin etc then it beeps and resets in a continuous loop. I tried everything I could think of... removed everything (gpu/ram), one stick of ram in every slot... and couldn't get anything. Removing the hdd stopped the single beep but it kept restarting in a loop.

Specs:
Intel Core i5-4460 3.20GHz
Sapphire Radeon R9 270X
Samsung 120GB SSD 840 EVO
TeamGroup Elite Black 8GB (2x4GB) DDR3 PC3-12800C11 1600MHz
Gigabyte B85M-DS3H Intel B85 (Socket 1150) DDR3 Micro ATX Motherboard

Also using an older Corsair 400w psu, which should be sufficient I would have thought.

Ended up putting his old parts back in the box... any ideas?

was the additional 8pin connected in mobo? was the CPU fan correctly installed and plugged in?

Try a CMOS reset -sometime helps and also cheek the socket for bent pins.

Yes the CPU power was connected! I double and triple checked as was the CPU fan.

Didn't have a jumper but I took the battery out, which I assumed would clear the CMOS. Yeah, checked for bent pins but it was all good.

Have you got another psu you could try it with?

Was pondering that, my 2 thoughts were: mobo is DOA or maybe the psu was not up to it. The beep means its passed POST right? So it really could be the PSU...

I had a similar problem to this with a gigabyte z77 and it turned out to be the board at fault.

Are you sure the bios is up to date enough for the cpu? rev 1.1 of the board ships with the f4 bios and it's possible your cpu wasn't added until the f5 bios.
I could be wrong but might be worth looking into.

Wow, I hadn't even considered this! No idea how I would check that or even flash the bios if I can't get the machine to boot.

The board or box should state what rev board you have got.

Says Rev 1.1 on the box, does that mean it has the f5 bios?

im only seeing f5 f6 bios's on giga website,it would say f4 aswell I think if it ships with that

your better of emailing gigabyte uk and asking them,they will probably ask you to send the board in for flashing

only other way would be to buy the cheapest Pentium cpu and using that to flash bios with
