New video card problems.

Last response: in Systems
Share

Hello,
I recently upgraded my PC from a Radian HD 5570 card to an Nvidea GTX 660 card. I installed all the new drivers and such from the disk and updated. But shortly after, my computer suddenly switched from transparent menu boxes / taskbar (windows 7 ultimate) to the pale blue one (basic). Right after, it started making a high pitched whining (the computer, not the speakers). What's going on?

Specs:
CPU: i3 dual core at 3.10
RAM: 8 Gb
HDD: 1 Tb
GPU: GTX 660
OS: Windows 7 Ultimate

-__- Just read that you NEED both of the power things plugged in. I only used one because it was the only free one. I guess that could explain the noise and the random visual downgrade at times. I guess I need to buy a new power supply so that I have all the cords I need...

Hmmm, the black cord that goes into my bid card only has 5 of the 6 wires. I have a free identical cord that goes into the p.s. but it has all 6 wires. Could I just plug that one in? The new cord reads as a pci express with another head that reads as ski ready.

hello... google pcie power adapter... a molex connector is the typical power connector that is the flat/one row of 4 female socket/pins connectors from your power supply... and it will have wires going to 2 rows of 3 female socket/pins connector for your Graphic Card.

This item can be bought locallly... what stores are near you?
