Running Windows 10 Pro version 1803 on a HP 700-327c, 16 GB, (Intel i7-4770 CPU in 64bit mode.
I have two monitors installed.
It has been working fine for a few years.
The TDR errors started infrequently but have progressed until the machine became unusable.
Scans report that drivers are ok.
I removed the AMD Radeon HD 5450 and now the computer works ok with the embedded Intel adapter.
I think the AMD board has failed but hoping there could be something else?
