Ok so, I have a AMD Radeon HD 7470
Slot Type PCI Express 2.1 x16
Video Output DVI-I and DisplayPort
Memory Size 1 GB

I installed it into a an HP Pavillion a6803w Desktop
With a PSU of 300w

I have onboard graphics.
I installed my GPU card,
Booted up my PC after
Downloaded the necessary updates & drivers.
Powered down my PC and connect my VGA to my new video card.

Booted up my PC again had weird issues, including freezing at log on screen,
Weird crashes or freezes almost in minutes of log on
& at one point my network adapter stopped functioning and showed the yellow triangle with the ! symbol.

I really want to get this thing up and going so any advice would be ideal

Thank you!

The 7470 recommends a 400w psu or greater. It should still boot up though but most likely that psu is not adequate.

If you can try maybe a friends psu that is much larger? or go back to the old card again and see if you have problems.
If you still have problems you know it may be the psu or the actual card displaying incorrectly.
