Hi,
I want to upgrade my motherboard and case and power supply unit for my desktop computer. I currently have 6gb ram, amd opetron, 8800gt 512mb, 2 harddrive (one is IDE and other is sata II). I upgraded my cpu recently, and unfortunately it is making terrible noise. I wonder if it is because my motherboard is Asus M2a-vm (costed like 70-80 dollars), or if it running low on power. My psu is only 500v.

Can someone suggest a new motherboard and PSU for my system?
