Resolving a graphics processing unit problem
Learn about the possible problems and service actions that you can perform to resolve a graphics
processing unit (GPU) problem.
Note:
To determine the location of the GPU, see “Identifying the location of the GPU by using the slot
Table 6. GPU problems and service actions
Problem
Service action
System unable to find GPU
1.
Verify that the GPU is properly seated in a
compatible slot.
2.
Install the GPU in a different compatible slot.
3.
Verify that the drivers for the GPU are installed.
4.
Verify that the most recent firmware is installed on
the system, or install the most recent firmware if it is
not already installed.
5.
Restart the system.
6.
Replace the GPU.
7.
Replace the system backplane.
8.
Replace the central processing unit (CPU).
GPU suddenly stops working
1.
If the system was recently installed, moved, serviced,
or upgraded, verify that the GPU is seated properly
and all associated cables are connected correctly.
2.
Inspect the PCIe socket and verify that there is no
dirt or debris in the socket.
3.
Inspect the card and verify that it is not physically
damaged.
4.
Verify that all cables are properly seated and are not
physically damaged. If you recently added one or
more new adapters, remove them and then test to
determine whether the failing adapter is functioning
properly again. If the graphics adapter is functioning
again, review the IBM support tips to confirm that
there are no PCI address, driver, or firmware
conflicts. Then, reinstall the new adapters again one
at a time until all adapters function properly.
5.
Replace the GPU.
6.
Replace the system backplane.
7.
Replace the central processing unit (CPU).
