hm it could be, try removing the card and putting your old one and running with the new power supply so you can isolate the problem to the graphic card.

2.1s have problems working on 1.0 pci-e slots

tell me your result because i also have a 1.0 slot :( ...
 
What version is your card? 2.0? 2.1?
What pcie slot version is your motherboard? 1.0? 2.0?

Many issues with 2.1 cards running on 1.0 board...
Your PSU is fine, even 250W-300W PSU can handle HD5670...

wait a second did you plug in the 6-pin power connector to the 5770?

also what was your old graphic card, was it alot lower powered, im thinking it could be your power supply it only has a total of 300watts on the 12v line split into two rails.... makes for only (300W/12v)= 25 amps

check out this guide: http://www.tomshardware.com/forum/279391-28-power-requirements-specs-popular-graphic-cards-guide

it says 37 amps is required and it should run on 30 amps for the 5770 plus you need a 450 watt power supply it says

here use this power calculator and see what your total power requirement for your system is:

EDIT: yes it looks like your power supply doesnt even have a 6-pin connector.... well theres your problem lol
