GA-770T-USB3 - Randomly detects video card

[Elderusr]

Hello Everyone,

First time poster. I have recently bought myself a GA-770T-USB3 Motherboard. I have verified all specifications with the motherboard for compatibility with other hardware in my system, please see the system specs below:

Mobo: GA-770T-USB3
Ram: G.SKILL F3-10666CL9D-8GBSR Sniper SE 8GB 2X4GB DDR3-1333 CL9-9-9-24 1.5V
Video Card: Sapphire Radeon HD 5570
CPU: AMD Phenom II X6 1090T Black Edition Thuban 6 Core Processor 3.2GHZ AM3
HDs: 2x Seagate Barracuda ST31000524AS 7200.12 1TB SATA 32MB Cache
Power Supply: PC Power & Cooling Silencer Mk II 650W SLI Certified
Chassis: Coolermaster Elite 370 Black Mid Tower ATX Case 3X5.25 1X3.5 5X3.5INT No PS

So, here is my dilemma; Based on the above specifications I made sure everything was compatible, and all of the hardware is, however here is my problem from time to time (more often than not) my video card does not seem to work; I have tried replacing the Video Card with another PCIx16 video card and testing (same results) and moved the one that was not working to another system to make sure it was functioning properly and in the other system it works great. I am using default settings as of current, however I would like to eventually have Virtualization support turned on in the Motherboard, but if I am unable to get this working with it on or off, its pretty much useless to me. Any help would be appreciated, however where it does happen from time to time, I believe it may be a grounding problem however what would be the simplest way to test this.

Once again, any help would be beneficial as next step is trying a different chassis or motherboard...

Hi there,

The first thing I would do is check that you have the latest BIOS version for your motherboard. You don't say which revisioin your motherboard is but you can find the latest BIOS version by clicking on the correct link for your board here: http://www.gigabyte.com/support-downloads/download-center.aspx?kw=GA-770T-USB3

Secondly rather than investing in a new PC Case try building the PC on a cardboard box and see if you still get the problem. That will show if it is a grounding problem or not.

I will be trying that this afternoon building the system on a piece of wood/cardboard and seeing if I get any different results. Also, I have noticed that there is a BIOS update for my system "F5A" stating that it supports the newer CPUs, which honestly shouldn't apply as when initially purchasing the system it stated that it would support my processor.

Hypothetically speaking, if I was to update my BIOS to this BETA BIOS just for testing, what would be the best method?

Thanks,
Josh

Hi Josh,

don't be fooled by the very brief description given to BIOS updates as it could also include further information for your system than just new CPU codes. I would try the BIOS update before I stripped the PC down and rebuild it outside of the case as it may just need that to cure your problem.

To update your BIOS we recommend that you use the QFlash Utility. If you're not sure how to go about that check here: http://forum.giga-byte.co.uk/index.php/topic,2441.0.html

Remember to disable the "Keep DMI Data" option on the QFlash home screen before you actually do the update.

If you have any specific questions about updating your BIOS post back and we'll do our best to help you out.
