I downgraded to previous BIOS, but same problem stands.
Also, I launched Intel Platform Confidence Test from EFI shell, and it was completed successfully.
Someone can tell me what "Satus Code 69" is? No references found into manual...
Your problem could be related to poor/faulty power supply. System could hang if there is unstable or low voltage.
Give us model of your power supply.
Thanks for your reply.
It is a Seasonic X-460. Scarcely you'll find a better psu in desktop range. It worked 3 months with another mainboard with no issues.
Also I installed a pcie 1x USB addon card, with 4 ports. If I connect any usb device to this card, avoiding mainboard native usb ports, the system is rock solid (although the message persists)...
I don't know much about those PSU, but basing on I've read, it should be OK.
What kind of devices you are connecting to USB ports?
Where you are seeing the "status code" message?
Thanks again for your support.
I connected printers, plotters, and wifi plugs for some keyboards and mouses. No power-hungry usb devices.
I got (and still getting) cited message from Intel Active System Console for windows.
As I understand, the problem occurs when you are using USB sockets from chassis which are connected to outstanding pins from motherboard.
Does it also occur when you plug devices to the rear USB sockets on motherboard?
off topic: could you give me a model of your RAM modules?
Unfortunately, the problems affects internal as well as rear usb connectors. I connected to a rear port even a self-powered usb hub, but again, if I plug more than a pair of devices in the hub, things begin to go bad.
My ram: 4 x kingston KVR13E9/8I (Intel certified).
OK, let's assume for now that it is only software issue.
PART I - get rid of all USB devices
1) Allow Remote Desktop access to machine,
I understand that you are using USB keyboard and mice, but we need to deal without them, that's why you must login to Windows via Remote Desktop,
2) Power down machine,
3) Unplug all USB devices while machine is off,
4) Disconnect all USB devices,
5) Power on machine,
6) Login via Remote Desktop.
PART II - remove all USB devices from system
1) Download the following tool: http://www.nirsoft.net/utils/usbdeview-x64.zip
2) Run above tool with Administrative privileges,
3) Find all USB devices that you can recognize - keyboards, mice, plotters, even USB sticks, right click on them and delete each,
4) Close the program.
PART III - do real driver update
(real, because in normal setup.exe-double-click you will not update all drivers, because setup program incorrectly assumes that update'ing some drivers is not neccessary)
1) Download the newest chipset drivers for your MB from Intel's Download Center (click this link),
2) Unzip downloaded file,
3) Run Command Prompt (cmd.exe) with Administrative privileges,
4) In Command Prompt, go to folder where drivers were extracted (using 'cd' command),
5) Invoke the following command: setup.exe -overall -overide
6) Installation wizard will appear, install as usual,
7) Reboot machine.
PART IV - reconnect devices
1) Connect first device,
2) Wait for graceful installation,
3) Validate for some time if the device is working properly,
4) Connect second device and do the same as above,
5) Connect third device and do the same as above,
... and so on.
I wish you luck and I'm looking foward for your results!
PS Thank you for providing me RAM model - I'm using the same in new servers and was unable to find other brands to consider. I really like Kingston, but I was dissapointed that those modules are based on ELPIDA chips. Some time ago it was Hynix, maybe ELPIDA is OK now, I don't know, there were my first chips based on it. But nevermind, I've tested them really hard and no error occured, speed is also very satisfactory.
And I have replied you about checking ECC availability here: Re: S1200BTLR, some questions
Thanks for you detailed reply. Before trying it, however, I gotta say a thing: USB problems were present even *before* OS installation. If you plug in enough usb deviced, the mobo hangs at bios POST.
Also, I booted with various linux live distros: same usb problems as for windows.
The ram: It is true that ELPIDA is considered a bit "low-end". If you want Hynix chips consider Crucial ecc ram sticks.
I understand that you are using the newest version of firmware. Have you tried complete BIOS reset (I mean: using jumper on motherboard)?
I also assume, that USB devices are not faulty, cables and sockets are OK and you've tried with other devices with the same results?
All usb devices work fine on others workstations, with same cables.
However, I did not try complete bios reset via jumper, having fear of messing things even worse. If I'll reset bios via jumper, it will be brought to factory version?
>> If I'll reset bios via jumper, it will be brought to factory version?
Yes, you can do this safely, without any worry.
It has sorted no effects. Same problem stands.
Sorry to hear that
Please attach settings from BIOS -> Advanced -> USB Configuration.
This may sound unrelated, but set in BIOS following options:
Advanced -> PCI Configuration
Dual Monitor Video: DISABLED
Wake on LAN (PME): DISABLED
Onboard NIC1 ROM: DISABLED
Onboard NIC2 ROM: DISABLED
...the same for rest NIC ROMs
