I take it you are wanting to replace your CPU and RAM? Hardware faults won't go away if the CPU and/or RAM aren't the damaged components. Aside from a good surge protector (I like Tripp Lite), a good CPU and RAM for that motherboard should be easy to find. Consider updating your hard drive if it is five years old or more.
Before we get started, you mentioned you replaced your motherboard, did you reinstall Windows after doing this? If you didn't BSOD's and other odd problems will almost certainly happen.
CPU: For your motherboard, you can take almost any 95W AM3 CPU out right now. However, with the release of the new FX CPU's, they are becoming more and more rare. At the high-end you can use the AMD Phenom II X6 1045T Thuban 2.7GHz
. At the mid-range, the AMD Phenom II X4 960T Zosma 3.0GHz
. At the low-end the AMD Athlon II X3 460 Rana 3.4GHz
. If you're developing content, the X6 CPU is great, if you're just gaming, the X4, and if you are a light gamer or generic home user, the Athlon II. Regardless of whichever you choose, make absolutely sure your motherboard's BIOS is up-to-date before installing the new CPU as all of these CPU's require new BIOS versions.
RAM: That motherboard can take up to two DDR3 RAM sticks, so I would get one or two AMD Entertainment Edition 4GB 240-Pin DDR3 SDRAM DDR3 1600
DIMM's. Your motherboard can take DDR2 or DDR3, I don't suggest mixing and matching, I also suggest reading the motherboard manual to see which goes where.
GPU: You can also get either the MSI R7750-PMD1GD5/OC Radeon HD 7750 1GB
or the MSI R7770-2PMD1GD5/OC Radeon HD 7770 GHz Edition 1GB
would be great, with the 7750 being the better value. Make sure you have a good enough power supply and your case is large enough before purchasing.
