Windows 7: BSOD IRQL_not_less_or_equal 0xA

Ok got them now and the dump below in code is a very common one and could be literally anything so it means digging through the BSOD dump which I must admit are more than I would put up with.

Probably caused by : ntoskrnl.exe ( nt+12452f )
Now there is this one too

SYMBOL_NAME:  IOMap64+1734

FOLLOWUP_NAME:  MachineOwner

IMAGE_NAME:  IOMap64.sys


This is something to do with the Asus GPU Tweaking software so are you using that or not? If so it might be an idea to uninstall it for now.

So lets try that first while I go digging elsewhere. By the way it is no trouble and you are not wasting my or anybody's time ti waht we do, plus the fact I am banged up in hospital right now with a broken leg and have a lot of spare time

Just a quick reply now Duncan there is one problem device listed in the msinfo32 - see pic and I suggest you update the driver for the USB. Trouble is there are two listed in the Gigabyte site GIGABYTE - Motherboard - Socket 1155 - GA-Z77-D3H (rev. 1.0) and to find the right one it mightbe an idea to run PART B: of this ditty of mine.

Using HW Info
You can test the volts on the PSU with HW Info HWiNFO, HWiNFO32/64 - Download < download the right bit version and close the right hand window select Sensors and scroll down to the power section where you will see what the volts are doing see my pic. In my pic the section (Nuvoton) with VBATT as a dead give away you are in the section for the rail voltages. There are other section titles and one that pops up often is ITE (sometimes the usual one for Gigabyte boards)
Now the voltage on the different rails have to be within 5% =+/- of what is required or the machine will not work properly if at all.
Limits +/- (minimum - correct - maximum)
12v1 = 11.4 - 12 - 12.6v
12v2 = 11.4 - 12- 12.6v
5v = 4.75 5 - 5.25v
3.3v = 3.135 3 3.465v
-12v = -10.80 - -12 - -13.20v
+5VSB = 4.75 5 - 5.25v
The Power good signal voltage at pin 8 on the 24 pin plug (grey cable) should be the same as the 5v rail reading/s
See this for the rail voltage info
PSUs 101: A Detailed Look Into Power Supplies (Section 2.)
The original right hand window shows the machine running and is handy for that but for looking at the components in some detail close it and use the main left hand side panel
Open each small square with + in it on the section the components are in and then click on the individual component/s (it will highlight in blue) - in the right hand side will appear all sorts of details including brands speeds and other essential info that particular device. See pic for example.
