Just to close this thread, two issues caused this:
- Failing HDD that haz been replaced and now pc boorz up jn a few seconds
- Browser hardware accelerators switched off and now browsing is uber fast.
Lessons learnt:
- HP diagnostic software is not up to speed.
- GPU architecture does not favour hardware acceleration, its well known by HP support staff for this i7 but not part kf the support packages.
- In this 4IR we have limited skilld to support tech
Over and out.
