GPU Graphical Glitches (And a few other problems)

I recently built my new computer and have been incredibly happy with it. However I have noticed a few things here and there that aren't quite right.

-Graphical Glitches when a desktop (Usually when Bitcoin mining or when idle (underclocked to 300MHz)
-Input Problems, When using a wireless keyboard or mouse, the input tends to freeze up and not work so well (stuttering with input, etc.)
-System Freeze Up, The system will randomly freeze up from time to time, however it can usually be resolved with CTRL-ALT-DEL (I have been told it's a memory problem)

My Specs:
AMD Radeon HD 7770 (XFX Black Edition DD 1095MHz)
Intel Core i3-2125
Gigabyte GA-H61M-DS2H
AMD Entertainment Edition RAM (1X4GB 1333MHz)
XFX Pro 550w PSU
Seagate Barracuda 200GB Sata I HDD (Will be upgrading soon)

More about graphical glitches problems
  1. Its hard to be sure , and it would have helped if you had mentioned your operating system and whether its 32 bit or 64 bit

    But Id suggest doubling the RAM so it runs in dual channel .
  2. Windows 7 64 Bit
  3. Then more RAM , in dual channel configuration + make sure the RAM is set too its correct timings and voltage

    That will probably help with the slow downs and stuttering
  4. well sure but it is a brand new system?

    update your bios(this may fix the freezes it did for me)

    and try onboard graphics(im not sure if the i3 has it but im pretty sure that it does so be sure to test that.

    hope this helps
