NVIDIA's GeForce servers are now back online following a massive global outage on Sunday afternoon.

The server outage peaked around 2:56 PM EST but has since dropped down after four hours, according to Downdetector.

NVIDIA earlier confirmed that it is "aware" of the issue but did not provide information as to why the global outage happened in the first place.

As of press time, all GeForce servers have returned to "Operational" status.

NVIDIA GeForce Suffers Several Server Issues

It is worth noting that the server outage came after NVIDIA notified users that they might suddenly not be able to launch their games via the GeForce app last week.

In some cases, NVIDIA noted users might also notice their video screen freeze in the upper left corner of the screen.

The company did not provide much explanation for the cause of the error but said that it "is working on the issue now."

NVIDIA advised affected users to temporarily use its web client platform as a workaround.

Server Outage Effects on GeForce GPUs

So far, no reports indicate that the server outage caused a major impact on the NVIDIA GPUs in the PCs and laptops.

To make sure, however, users can do a quick diagnosis to check if their graphics card was damaged or slowed down by the outage.

This can be done by accessing their DirectX diagnostic tool or opening the "Run" software for Windows computers and typing out the "dxdiag" to see the current status of their hardware.

Conducting a web GPU stress test is also recommended to see if the unit's performance remains at optimal condition.

If there is a problem detected, immediately contact NVIDIA's customer assistance site or go to the nearest tech hardware store to fix the issue.
