I'm having very strange issue with my Z620 since I have updated to latest bios: 3.88 last week. When working for more than couple of hours Z620 suddenly freezes. It doesn't react on keyboard or mouse. Video is gone. I can still ping to it though but I'm not able to connect with remote desktop. I have checked power plan settings within Windows and it's set up to not going to sleep as I suspect it could be a problem with waking up the machine.
All drivers are up to date and it's quite fresh Windows 10 install. Thermal status of CPU, GPU and hdd is within the limits since I though it could be an overhiting issue so I have started to monitior it with HWiNFO64.
I can aonly suspect that bios 3.88 has something to do with it is since it was not an issue with 3.87.
I would like to downgrade bios in my Z620 to the previous version - 3.87 but I can't find it.
Where can I get this file? I have looked in HP public FTP sites but all bios files are unavailable.
