I thought I would post what I have learnt and tried so far in case anyone has any comments or can think of anything else +
it will help me remember what to try next time
Run dxdiag
No problems reported
Change game settings
Ongoing
Change GPU settings
Ongoing
Test temperature
Used Core Temp – no problems found
Increase fan speed
Could try SpeedFan but doesn’t seem worthwhile as temps seem OK
Test memory
Used memtest – no problems found
Test hard drive
Run chkdsk /r - no effect
Run CrystalDisk info – to do
General system scan
Run AdvancedSystemCare 6.2 – no problems found
Take out battery
Appears to work with decreasing effect
Could this suggest instead a loose connection which changes as PC is moved about
Push in internal connections and remove dust (wiggle about and blow)
Done - possible improvement. No crash since - but dust in eyes and up nose.
Remove RAM in turn
To do
GPU driver updates
Tried auto installs and custom installs of old, current and beta drivers – no improvement
Tried after an uninstall but this had a near catastrophic effect as the graphics adaptor could no longer be found.
This seemed to fix itself the next day.
Could try Driver Sweeper
Disable on-board audio in boot menu
To do
HDMI audio driver
Disabled – no effect
Try DX9 or DX10
Worth a try?
Flush BIOS
Downloaded Asus BIOS update program for W7/64 but get an incompatible OS message when I try and run it
Could try EZ Flash2
Underclock or overclock
Updated the registry with coolbits but no new option appears in the NVIDIA submenu
Ran Rivatuner but no option to underclock was given
FPS Cap
?
Up voltage
To do
The only reason I have not yet bought a new PC is the nagging worry that it might also crash - a lot of people seem to report similar problems.
As our friends across the pond would say - that would really suck!
Cheers,
Chris
