Can someone help me?

I have a problem with my PC, since i bought a new graphics card (NVIDIA geForce GT 730 2GB version) The driver (graphic) started crashing, when i play like new games such as (NFS Rivals ) and even when i am on Firefox sometimes i get like wierd colors on the screen and i have to shut firefox down so it can stabilize my PC is kinda old but, i didn`t have any problems with my PC with my old graphics card (512 MB) this is happening with the New One. BTW I have the requrements for the Graphics card such as the power supply wattage ..

CPU: AMD Athlon 64 x2 5200 + 2.7 GHz (overclocked to 3.0GHz)
RAM : 3 GB
Windows 7 Ultimate 64 Bit

*Cough* 1 word UPGRADE



Your GPU right now is shit you shouldn't have bought it sorry to bring it to you but your PC sucks as of right now.

Sure That'd be enough lad go for it but I recommend not getting a pre-built waste of money ofcourse.

Honestly I'd just upgrade your entire rig. There are a few sites out there that you can use to build your computer and price everything out and find the best pricing from multiple retailers. Just search around for em!
