Thanks for the in depth response!

AVG is gone, MSE installed. No malware or viruses found

sptd.sys removed

New drivers unavailable - holding on to the existing ones for now, unless BSOD continues

System files checked and passed

No rootkits found

CPU Heat 30-40C

HDD screen shots attached and drives pass testing

Waiting to see if problem persists
Thanks again. I'll report back if there are issues

Hi JackLoy.

Are you overclocking?
As you are getting BSODs, you should stop overclocking and run all the hardware components like CPU, GPU and RAM to their default settings.

Uninstall these bloatware:
  • Start Menu\Programs\GIGABYTE
  • Start Menu\Programs\GIGABYTE\3DPower
  • Start Menu\Programs\GIGABYTE\AutoGreen
  • Start Menu\Programs\GIGABYTE\ET6
Befor uninstalling ET6, run it and set everything back to default, without miss.

Uninstall Marvell 91xx SATA 6G Controller.

Get @BIOS from GIGABYTE - Motherboard - Socket 1155 - GA-Z77X-UD3H (rev. 1.0) > Support & Download > Utility; Update your BIOS to the latest using it.

Also, Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

Let us know the results.

My 2 cents worth Mate I know this is a recent build but worth checking out the PSU too because it is like anything else just because it may be a good brand and price doesn't mean it is naturally faultless or just has one small part go south. So use this


Test the sockets and leads with a digital multimeter NOT an analogue one because an analogue one injects 9v into a circuit which I am sure will know will do no good the board!!

Something like this is ideal

Another good ref

Plus when testing place the black lead to the case or one of the board fixing screws try not to use the blacks in the 24 socket - you can but the other site are for more reliable for preciseness. In fact you can get crocodile clips to fit the black probe to attach and forget leaving one hand free

Now you have to remember of course correct volts does not always mean correct current.

Think of it as a car with a flat battery it may test perfect at 12 - 13v but try and crank the engine it may do that but leave no available current for the ignition and other essential circuits.

To test though you will need a fairly good ammeter and run a known current draw though it however these are usually expensive pieces of equipment and is not really THAT necessary. .

Use this for volts refs and they need to be within 5% of the stated voltage - see text in this,3061-2.html

Doesn't take long but a word of WARNING -DO NOT attempt to disassemble the PSU in any way unless you know what you are doing with it.
