I replaced my gpu with Radeon HD 7790, got it put in.. But when I turn on the computer, there's no display and the fan isn't spinning. What could be the problem?

Did you plug in the power cable?

Did you connect the power cable to the GPU? If so, you may need a better PSU.

350 W is not enough and probably has no 6-pin pcie connector...get at least 450W with pcie-e 6 pin..
