Quick Answer

For a RTX 5070 build that has crashing or low FPS after a GPU driver update, the fastest safe path is to perform a clean driver install, clear shader caches, remove unstable overlays, and retest with the previous known-good driver if the new package is worse. Do that before assuming the R14,000-R22,000 class hardware has failed. A healthy setup should return to its normal target, such as 1440p high refresh or 4K gaming with 32GB RAM, without repeat crashes, black screens, shader stutter, Event Viewer display resets, or sudden 1% low drops.

First Checks Before Reinstalling Anything

Write down the driver or BIOS version currently installed, the Windows 11 build, and the exact error code or behaviour. Test once with background overlays closed and once with the monitor at a conservative setting such as 120Hz instead of 165Hz. If the problem started immediately after one update, that timeline is more useful than random part swapping.

Clean Recovery Steps

Start with the least risky move: roll back the driver from Windows or the GPU control app if that option is available. If crashes continue, boot into Safe Mode, remove the current display driver cleanly, then install a stable package from the GPU vendor. For BIOS-related boot trouble, do not keep flashing repeatedly; use the board or device recovery method and keep power stable for the full process.

Hardware And Settings To Verify

Check temperatures under load: a GPU near 80C can be normal, but hotspot readings above 100C, sudden fan spikes, or PSU shutdowns need attention. Confirm PCIe power cables are seated, EXPO/XMP is not causing memory errors, and the system can pass a 20-minute game test without a crash. For SA buyers, also keep invoice and warranty details ready before requesting support.

FAQ

Should I update the BIOS again if the PC will not boot?

No. Use the proper recovery route first and avoid repeated flashing attempts. A failed second flash can turn a recoverable problem into a board-level support case.

Can one driver update really cause low FPS or crashes?

Yes. Shader cache changes, overlay conflicts, and profile resets can drop 1% lows by 20-40 fps in heavy games even when average FPS still looks normal.

When should I contact support instead of testing more?

Contact support when crashes continue after a clean driver install, stock clocks, safe memory settings, and a known-good cable or display mode. Keep the error code, invoice, and test notes together.

Stabilise the system before judging the part. Retest at stock settings, one monitor mode, and one known-good driver; then decide whether the next step is a settings fix, cable change, or warranty support.
