HP Envy 16 Intel Arc A370M Driver Error Code 43 Windows 11

The Intel Arc A370M in your HP Envy 16 shows Error Code 43 in Device Manager – Windows has stopped this device because it has reported problems. Games and creative applications do not use the discrete Arc GPU and performance relies entirely on the integrated Intel Iris Xe graphics.

This guide covers the Intel Driver Support Assistant cleanup, HP-specific driver installation, and BIOS checks to resolve Code 43 on the Intel Arc A370M in HP Envy 16.

“My HP Envy 16 Arc A370M showed Code 43 right after a Windows update. Adobe Premiere stopped using hardware encoding. HP Support driver reinstall fixed Code 43 and brought back Arc hardware encoding.” – Jun Hao, content creator from Petaling Jaya

Why Intel Arc A370M Shows Code 43 on HP Envy 16

Intel Arc A370M Error Code 43 on HP Envy 16 occurs when the Windows 11 generic Intel driver is installed instead of the HP-optimized Arc driver, or when a partial driver update leaves conflicting driver files. Intel Arc requires complete clean installation – partial updates reliably cause Code 43 on this platform.

• Generic Intel Arc driver from Intel.com not fully compatible with HP Envy 16 power management
• Partial Windows Update driver replacement leaves conflicting Arc driver files
• Intel Arc A370M shows Code 43 after Windows 11 feature update
• HP Envy 16 BIOS needs update for Intel Arc driver version compatibility

Fix 1 – Use Intel Driver Support Assistant for Clean Remove

Download Intel Driver Support Assistant (Intel DSA) from intel.com/support/detect. Run it and select Uninstall Intel Graphics Driver. After removal, restart. Then go to support.hp.com/us-en/drivers, enter your HP Envy 16 service tag, and download the Intel Arc Graphics driver specifically published for the HP Envy 16. Install this HP-qualified driver, not the generic Intel Arc driver from Intel.com.

Fix 2 – Update HP BIOS

Check for HP BIOS updates via HP Support Assistant or HP Support website. BIOS version 1.08 and later for HP Envy 16 include improved Intel Arc power management that prevents Code 43 on cold boot. The BIOS update requires the laptop to be plugged in and takes 3-5 minutes. After updating, re-enable XMP if you had it enabled and re-enable any custom BIOS settings.

Registry Check for Intel Arc

After driver reinstallation, verify the driver is loaded by opening Registry Editor and checking HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\igfx. The Start value should be 1 (System). If it is 4 (Disabled), the driver was disabled during update. Change to 1 and restart. Intel Arc graphics use the same igfx service name as integrated Intel graphics.

Fix 3 – Verify Arc A370M in Intel Arc Control

After driver installation, open Intel Arc Control (installed alongside the driver). The System dashboard should show both Intel Iris Xe (integrated) and Intel Arc A370M (discrete) listed. If only Iris Xe appears, the Arc driver did not install correctly. Re-run the installation with Clean Install option selected.

Fix 4 – Force Arc GPU for Creative Apps

Once Arc A370M is recognized, set it as the GPU for Adobe applications. In Windows Settings – System – Display – Graphics, browse to the Adobe application executable and set it to High Performance. In Intel Arc Control – Gaming, add the application and set GPU to Arc A370M. This enables AV1 hardware encoding and 4K decode acceleration in creative apps.
