Z440 Trouble with GPU

[bfbs22]

Hi, when I start up W10-Pro, the icons won't show up, it still looks like the log screen.

Have to open a browser or something and then they appear.

Have tried everything in BIOS, drivers and settings, nothing helps.
Two different GPU, HP, W10 and nVidia drivers, nothing.

Z440
E5-1620 v3 / E5-2650 v4
32gb DDR4 Hynix 2133 / Samsung 2133
HP Turbo Drive / SSD
First Quadro K2000, now switched to K420

W10-64 Pro updated / no updates

Very clean install
MBR / GPT
Original HP Quadro drivers / nVidia / Microsoft default drivers

Out of tricks now, any help would be very welcome.

Thanks.

hi

try creating a new admin user account
to see if it works

Hi, thanks for quick reply, because of music production I've already tried that.

hi

please perform the hardware tests
everything is explained in this link

HP PCs - Testing for Hardware Failures | HP® Customer Support

you may have an error code , failure ID (24-digit code) , as shown

if so, just give this code here and product Number P/N

"because of music production I've already tried that."

I don't understand the connection between what I said and this, but if you have the same problem with a new account, whatever the drivers tested, different gpus, difficult to know what can happen
"W10-64 Pro updated / no updates
Very clean install
MBR/GPT"
here, you mean that even after reinstalling windows 10 the problem comes back?

Ok, did all tests I could find.

The problem in detail:
- On W10 boot: after the password at the login screen,
  I see no icons on the desktop, but still the login screen.
- I have to open a browser or directory, or a lot of mouse movements,
  after which the appearance becomes normal.
  After that, all seems normal.
- Sometimes when I boot up, mostly after I changed something
  it starts the right way up,
  but the problem comes back after the next start up.

What I have done till now:
- All possible Bios settings done
- all latest HP drivers for Z440 W10-64
- all Windows settings plus W10 updates
- also tried nVidia drivers to no succes.
- The HP Turbo Drive will be cleaned in a Z420 in admin cmd,
  and given a new GPT + new default partition before installing W10 Pro via USB-3.
  There are no issues installing the OS at all,
  Also third party software works with no issues.
- Have tried E5-1620 v3 and E5-2650 v4.
- Have tried a set of Hynix and a set of Samsung DDR4.
- Have tried Quadro K2000 and K420.
- Have tried E5-1620 v3 and E5-2650 v4.
- The PC and PSU is fully cleaned, screws and cables are checked.
- W10 installed in Full UEFI several times.

Hardware at this moment:
- HP Z440, Workstation in original case
- BIOS, M60 v2.59
- TPM - v1.2, will be updated later
- E5-2650 v4, 1x
- 32gb DDR4 ecc 2133, all black sockets,
  4x Samsung M393A1G40DB0-CPB0Q,
  213P, 1Rx4, PC4, 8GB, 752368-581

Populated PCIe's according to pdf, including HP Turbo Drive installed.
PCIe 1 - empty, disabled
PCIe 2 - Quadro K420, HP driver W10-64 v8.1.940.0
PCIe 3 - Intel Pro 1000 PT
PCIe 4 - HP Turbo Drive 256, nvme pcie3
PCIe 5 - empty, disabled
PCI 6 - ESI Juli@, original W10 driver

OS:
W10 Pro 64, 22H2
- All w10 updates

TESTS

- All HP Diagnostic tests were done in admin.

HP Support Assistent
- Network = no problems found
- OS test = no problems found
- Audio = no problems found
- No updates needed

HP Hardware Diagnostics Windows 1.8.10
- Multimedia and others that ask for internet connection = can't connect to internet - LAN cable is in the onboard port -        Windows Edge has normal internet connection
- System test = all passed
- Video test = all passed, except update
- Mouse & Keyboard = all passed
- Network = no ping, irq = passed, rom = passed - [maybe my router won't let it, not sure]
- cpu = all passed

HP Docks & Displays Diagnostics Windows
- all passed

UEFI BIOS TEST
[inside bios]
- System board test : not available [?? not sure, maybe due to bios conf, nvme, other ??]
- pcie read device : passed
- memory : passed
- onboard video : not availabel [not sure if it means graphics on cpu, then it is correct, I have Quadro]
- audio : not availabel [correct onboard audio is hidden]
- usb : passed
All other tests here = passed

SSD/NVMe several checkers
- HP Turbo Drive 256 = all passed

OpenGL test
- all passed [what I understand]

Other
- VMX [VT-x] = marked red
Seems to be sitched off
  I have no clue if this is important or how to switch it on.

Temperatures
- all passed very good, 39 Celsius average

What more can I do, I'm not in to clocking cpu or tweaking gpu, or gaming.
I just need a stable workstation and this annoys me.
The only thing I will do after all works fine, is tweak the OS to my audio needs.
People come and ask me to check their PC, and I just can't get my own PC right LoL.

---

My findings:
- Bios test - system board test : not available
not sure what to think about this, all other works fine.
- Internet connection in 'HP Hardware diagnostics Windows'
does not seem to me, to be a graphical problem.
- Never had this kind of trouble on my Z420, Z600 and 8200, HP laptop
these machines were all on W10, Windows 8, Window 7, XP and Linux.

My thoughts:
So my guess is, that it is a W10 and/or Z440 motherboard problem,
but I can't find any others on the www that have the same problem.

Thank you very much for your time and effort.
