Help reset unstable overclock

[OfficialS_Face]

I have a gigabyte 290x that boots up with windows and can be seen in device manager however, after 10 mins or after opening up a program the whole system crashes. I think whats happenning is an overclock gone wrong and its stuck, as the GPU is always quite warm to the touch whenever i handle the card. However i cant figure out how to return the card to stock clocks as whenever i open up wattman for example the PC crashes.

Windows 10 (fresh install)
8 GB RAM.

P.S I've tried reinstallling OS and drivers, that doesnt seem to be the problem or help. (system's fine with my other cards). Also when plugging in the card to the monitor, it diplays veryy heavy artifacts which propels my theory even more.

In which mode is your card running? (Look at the switch near the card bracket) Move it to other positions!

Gigabyte, Especially R9 series, as we know prone to overheat, so will be better to run it on performance mode (switch switched near to the bracket)

Turn pc off and pull the power plug for 10 minutes.

The easiest thing to try is indeed to flip the BIOS switch when your PC is turned off. Could help indeed help.

Have you manually messed with different clock speeds in any programmes like MSI Afterburner or did the problem just came out of nowhere?
If you have just reset the clock speeds to factory settings(there was an option for that I think).

It actually depends on the type and manufacturer of GPU you have. I've seen it before that some GPUs will have a VBIOS switch while some will have nothing. The important thing to rememember is to not brick both of the vbioses available.

Make backups of your BIOS and don't overwrite both

These bios switch (on 290X) used for fan mode (silent mode or performance mode)

Silent Mode
Will be giving you a quiet fan (The fan runs at low speeds)

Performance Mode
The fan speed will be dynamically adjusted based on the GPU temperature to keep GPU temperature lower for the best performance.
