Hi There,



So I just built me a desktop and am having problems booting it up, the mobo light is on and the fans spin for a split second then it just stops spinning and nothing happens, (no beeps either).

Now i'm no newbie to building computers as I have built several and have a fair understanding of how computers work so to try and diagnose i've done the following.

• Checked all wires are connected properly
• Powered on the Computer with only the PSU, CPU and mobo connected
• Swapped with a known working PSU
• Double and Triple checked the CPU and CPU heatsink is connected properly

Yet still no matter what the computer does the same thing, green motherboard power indicator turns on, fans spin for a second then stop and nothing happens, no beeps no nothing. (btw I do have a mobo speaker connected directly onto the mobo)

Here's my Spec list

Asus Barebone V6-P8H61ELX (includes mobo, psu and case)
Intel Pentium G620 2.6GHz LGA1155(cpu is compatible with the mobo)
Crucial 4GB DDR3 RAM (2x2GB)
Samsung F1 320GB HDD
DVD Writer

I hope you guys can help me out here

I have performed no specific research on your system.

You are/maybe describing a condition where the CPU is supported, BUT NOT on the BIOS version currently installed on the mobo.

Or, a DOA mobo.

I'm pretty sure the BIOS supports it as the CPU is listed in the supported CPUs list on the manufacturers site, how can I test if its a faulty mobo?

0109 - First Release BIOS, supports G620 and G620T - so, it is not a BIOS issue.

Revisit

Confirm the known good PSU or try a different one. If the problem remains, mobo is dead.

The PSU is from my old computer and that's been working fine so the issue isn't with the PSU, however I contacted the person who I purchased the barebone from and he said that he tested it before selling it and it was working fine.

Is it at all possible the CPU was DOA? It was brand new and never tested.

We are at the branch that requires testing a known good PSU. What the seller claims is irrelevant. You have evidence that suggests the PSU is faulty. You could re-assemble the 'old computer' to test the PSU's current condition - your choice. But, two faulting PSUs is not likely.

A motherboard is much more likely to arrive DOA than a CPU is. Further, a faulting CPU will not necessarily/often/always prevent the mobo from loading BIOS. Check the CU and socket for pin damage.

Check your standoffs for a case short.

Else, my money is on [mobo DOA].

I know the fault isn't with the PSU as I took it out of my old computer which was working before and tested it with the rig and had the same results so i'm 99% sure it isn't the PSU.

I'll check the CPU and socket for damage then the standoffs in the morning.

Thanks for the help and quick responses

Hey Sorry for the late reply, I was on a trip and only got back a few days ago.

Here's an update, I've now got a new motherboard installed and things are now looking up, the computer turns on fans spin etc. but it doesn't POST, what does happen however is the MemOK function goes into action, it flashes for a while then restarts then flashes again then restarts again and repeat. Basically it keeps doing this i've read in the manual that this is how the board adjusts its settings for the RAM however its been doing this for a long time and its not stopping.

If the RAM was bad it would stay red but it just keeps flashing, i've tried resetting the CMOS with the jumper as it says in the manual but still nothing. Lastly nothing shows up on screen either I've connected it to my TV via a HDMI cable but nothing I am hoping this is because its stuck on the MemOK test?

So guys can you help me out with what went wrong, oh and the board is an ASUS P8H67-M LE

Thanks again.

Remove all RAM. Does it POST?

I get nothing on screen however, I get a long beep then two short beeps after it boots so it did POST right?

Please confirm video is properly connected.

You have faulty RAM. Test each stick, one at a time.

I'm not using a video card, i'm using the integrated graphics of the CPU, i've checked to make sure the wire is connected properly to the computer and TV but still no display. When I test the RAM they both go into the MemOK test and they stay blinking and restarting.

You have faulty RAM. Test the original mobo without RAM installed.

I already done that before getting the new motherboard, it switched on for 1 second where the fans spun for a second then it switched off. no beeps no POST at all.

Just wanted to give a heads up on what happened. Purchased some new RAM installed it and now everything is working fine. The display is good and the machine is up and running without a problem.

So you have my thanks again
