My friend gave my a Radeon 675 which was an upgrade over my former card so I decided I would try and install it.

I installed it into my computer after taking out the old one, but the monitor was getting no signal. Oh silly me I thought. I forgot to install the drivers.

So I reinstalled my old one and now the monitor is still not getting any signal. On top of that the power button on my.computer is not lighting up anymore. And it will only turn it on. Not off.

I'm clueless.

Maybe motherboard was damaged or power supply went bad or failed when trying to power up the new card.

What is the power supply brand and model? You can try to reset your BIOS to defaults (unplug system from power, remove CMOS battery for 30 seconds), see if at least your old card powers it up. If not, borrow a power supply to test with.
