amd 5450 crashing

[SpiritBear]

My dad has a Dell XPS 8700 desktop that has worked well for about 5 years now. The original gpu (AMD 5450) started to crash and so I replaced it with another AMD of the same model and it is now crashing again. The screen goes black and then comes back with the integrated kicked in. Then after this computer restarts on its own and comes back with the dedicated graphics working.

It happens about once a week and no heavy performance programs are running when it does.

Have tried to update the drivers from amd and the same thing happens.

Seems maybe like the computer is getting to hot, but IDK any help would be appreciated, Thanks.

was the replacement new?

does it have a fan on it?

did you uninstall the old drivers, shut down, pull the old card, install the new and reboot....... and either let windows find a driver or install one from AMD's site for the card?

 

did you disable the on board graphics in the BIOS?......... or turn it on auto or select proper avenue?

So the 5450 stopped working and you replaced it with ANOTHER 5450? that does not make any sense...
