The proper place for this question is on HP's support forums.
ok i will try that, but don't close this thread yet in case they bump me back to you again. thanks ...
I must have the same laptop here in australia, its a hp with amd a4 9120 and radeon r3. I had been getting the same issue after doing a few windows updates back in feb. I also noticed my avira antivirus playing up after updates.
I've since removed avira and am just using windows defender, i've downloaded all the latest windows updates that just came out and hp updates from support assistance and the issue hasn't come back but it has only been 2 days :S so fingers crossed.
I'm doing about to stress test the machine, with furmark/prime95 and pc mark just to check things out.
On a side note does your cpu clock speed throttle down to %50 when the gpu is active ? guessing its by design to save power... but can't find any info online.
I have been unable to progress the issue further with hp because naturally i took the laptops back and got my money back.
However today, the first time i have now got a similar error on my desktop that i have had for several years. It reset itself and gave the following entry in the log file.
A fatal hardware error has occurred.
Component: AMD Northbridge
Error Source: Machine Check Exception
Error Type: 11
Processor APIC ID: 0
It is a Compaq pc that was upgraded from Windows 7 to Windows 10. It has an AMD Athlon II X2 220 Processor.
What is going on with the AMD Northbridge component? Is it no longer compatible with Windows 10 if you install Windows Updates for example?
