GA-H55N-USB3(rev. 1.0) HDMI

[CallMark]

Hello

Built the following machine in July no problems....

SStone 500W MODULAR ST50F-230
4GB TW3X4G1333C9A XMS3 CLASSIC
SSUNG SH-S223L/RSMN SATA MULTI
Scythe SHURIKEN big CPU Cool
Intel Core i5 650 3.2G s1156 
LIANLI PC-Q07B BLK uITX CASE 
250GB WD WD2500BPVT 5400RPM 8M 
EW-7811Un 150Mbps SUPERSMALL
Gigabyte GA-H55N-USB3 Mini-ITX

The system was working fine on vga.
Now I've upgraded to hdmi and that's where all the troubles lie.
At the recommended rez 1920 x 1080 the machine will freeze then just switch off.
If I set the rez to 1650 x 1050 it no longer freezes or switches off.
It just gives a blank screen about 6 times an hour.

The bios version is F5
The intel HD Graphics driver is version  15.17.11.64.2202
Tested memory passed with memtest86+ 5 times run

Proc temp at idle is 36 rising to 58 c
System temp is 52 c

Can anyone advise the best solution for this.
Sent an email to gigabyte tech support no answer.


Many thanks in advance for help

Hi and welcome to the forum.
It would seem to be a overheating situation on the surface but your temperature readings are not overly high. Have you checked the temps when you get the problem?
Is that the latest graphics  driver that you have installed?

[CallMark]

Hi Thank you

Yes it's the latest graphics driver available from intel.
As soon as the issue occurs I reboot and check temps they seem ok.

I ran an intel burn test at maximum which took the proc up to 85 c on vga and it was stable.
It just seems to be when I use hdmi the problems arise.

I read somewhere on the US forums that using an i5 cpu is the problem.
Someone had posted saying that the board works well with an i3 but when an i5 comes near strange things happen.

Any other ideas would be much appreciated

Kind Regards

The only other suggestion I can make is to check the pins on the CPU socket and make sure there are no bent ones. There have been a spate of cases recently and not just Gigabyte but all Intel platforms. They are difficult to see but if you are in any doubt just take a couple of close up Macro shots and post them on here and we will check them for you.

Hi

Thanks for all your help in this.  Don't have access to system as it's with end user.
I will post pictures when I get it.  However here's an interesting thing the end user has reported.

The cpu fan is shutting down and thereafter the whole system freezes and shuts down.
Any idea why the fan would just stop working???

If you switch the system back on after the shutdown the fan is working again!

Weird

Thanks

Well the first thing I would check would be the fan itself maybe it's faulty and secondly I would check the BIOS settings for the fan and power savings.

You could test raising the GPU Voltage in the BIOS a little bit and see if that helps

Hi!
Did you get this resolved?
I have the same problem with a recent build with i3.
I have the latest bios,and the latest drivers for everything.
Some times the system just freeze and after about 10 seconds it powers off.
Some times i get flickering picture with lots of different colors, i then switch to another input on my TV and go back to the htpc and the picture is correct again.

Hi and welcome to the Gigabyte Forum.

Your problem would sound like an overheating one. Try checking the heatsink for the CPU and making sure it is solidly fixed down. If you are still running the stock cooler it is quite common for them to come loose.

[pellegj]

I can say it's not a overheating issue. I have read other forums, and it seems it's something to do with power saving options in BIOS that causes the power off's. I disabled the power saving stuff in BIOS (except the cpu fan pwm), and have not had a single power off since then.
Had it been a overheating issue, i should have heard cpu fan going at full rpm's first, but it never did, it only raised a little bit. I still have the fan set to auto, and no power off's.

[Dark Mantis]

I can't say that I am surprised. There a re an awful lot of problems that end with disabling the Power Savings Options.

@pellegj. Hi, could you post exactly which options you changed in the BIOS to disable power saving. I have the exact same issue with this mobo freezing and shutting off and would like to try your solution.

Thx

Hi and welcome to the Gigabyte Forum.

Try disabling C1E, C3 etc in the BIOS . If that doesn't help try disabling S1, S3 etc also. If still no joy disable EIST.

I hope I'm not thread jacking here, I have a very similiar problem.
The system:

Silverstone SG06-450
H55n-usb-3(rev-1)
Intel i7 870
MSI radon 6870 Twin Frozr
Patriot PSD38G1333K 8gb dual channel (currently)
Windows 7-64bit

The Problem:
Built the system (using Corsair CMX8GX3M2A1333C9 8gb dual channel) and it worked great for about two weeks. Then in the middle of WoW (the system's primary use) I get a black screen with a small box slowly bouncing around the screen say something like "not optimal resolution 1900x1200" or something very close. Total lock up, so I powered off. On restart, it won't even get as far as the bios or boot sequence.  The three (green/yellow/red) LED's on the mobo light up and stay lit, and after about 5-10 seconds the case power indicator begins to flash. No boot, can't boot from DVD, nada.  RMA'd the mobo, and upon rebuilding the system, I got  a brief flash of the Gigabyte poster (it looked like the box art) and then back to no boot, solid LED's, flashing case light. Thought maybe it wasn't seeing a HDD, replaced it, no change. Someone suggested defective memory, so I put one stick only in slot one, got one boot, shut it down normally to swap cables and then when powered up, back to no boot black screen.  Exchanged the memory for the Patriot and system booted up fine into safe mode, so I rebooted into regular windows and it worked great for about five minutes, then back to same black screen, same bouncing message.  Nothing is hot, nothing smells like burnt electronics, all fans are powering up, it seems the graphics card is outputting when it gets a boot...

Any chance it's still a memory compatibility issue and I should change to non-dual channel? Everything seems to be getting power, so I don't suspect the PSU, but...?


Thanks for your time,

Hi and welcome to the Gigabyte Forum.

On the face of it it would seem to be a graphics problem, as it is telling you that your screeen is running at an unsupported resolution. You haven't said what monitor you are viewing it on but try setting the resolution to the native one for the display. I take it that it is a LCD screen and they have an optimal resolution that they run at best. You can damage hardware by trying to overdrive it.
