Please try the steps below in order to troubleshoot this issue:
1. Update the BIOS of your motherboard.
2. Install the latest Intel HD graphics:
If this does not fix the issue, you may try the Graphics driver released by the system manufacturer as well, most of the times these drivers have been customized according with the motherboard specifications.
thanks for your reply,
as far as I know the BIOS and intel graphics drivers are all up to date.
I ran the intel update utility tool and that told me all the drivers were current and did not offer me any updates.
Likewise on the Asrock site there are no updates for BIOS available for my motherboard and allthough there is a VGA driver update listed on there I have no idea if I have that update as current or if it would be a genuine update for me.
I bought the motherboard,an Asrock Z68 Pro3 version, in the second week of May this year, only just after they were released as a product line.
The problem is definitely progressive and worsens continually.
It's been suggested that I should re-install windows so this is what I will try next.
Again,any idea's or suggestions would be most welcome in helping me to overcome this gremlin.
Yes that's the right list. Flash 1.50 or 1.60. Important is this one:
-Modify default setting for IGPU voltage.
With the older Bios IGP voltage is too low and might cause freezes- well known issue with Asrock Boards (especially Z68 Boards). You can also manually increase the IGP voltage with your old Bios, should work too.
thank you for your help.
It appears to be a voltage problem with the IGPU as having increased voltage to the GPU using the overclocking facility on the mobo has or has appeared to have resolved the problem.I expect an updating of the BIOS will totally clear it up.
I'm unsure who to award the full answer reponse to out of the both of you who replied or even if it is of importance to you so I'm going to give the 4 points to YUPS as his recommendation is the one I'm using now.
Thanks again for your help,
