I just installed a 400W Corsair PSU from Newegg, along with a Sapphire Radeon HD 5770, also from Newegg, on the same order. I'm having problems though.

Problem 1: Sometimes, upon powering up, the drives will spin up, and I can hear other noises, and the computer basically turns off, except the drives and fans don't stop. The light just turns off and then turns back on after about 2 seconds, and repeats the cycle, sometimes eventually turning on. I found that unplugging the 6-Pin from the GPU and plugging it back in will fix this and make it boot up.

Problem 2: Once powered up, if I try anything graphics intensive, like everything on Need for Speed Shift, there are white, pixel-sized specs almost everywhere, and the performance is low for what it should be.

Does this seem like a PSU weakness, or a Graphics memory problem like other articles suggest?

The links to the products are as follows:

GPU:
http://www.newegg.com/Product/Prod [...] 6814102864

PSU:
http://www.newegg.com/Product/Prod [...] 6817139008

The system works fine with the 2400 in my signature, and I think it's pretty self-explanatory if you look in the signature, it's the Gateway. I have already set up the RMA through Newegg for the GPU.
