I am new to hard ware stuff but my PC just gave up giving me long beeps, so did some research and I don't know if it's the Psu, Mobo, or Cpu, I don't know what type of Bios it has, I tried to find the manual but can't find it online(for some reason it can't be downloaded).
Now I decided to build a new one, using some old parts where possible.
I mainly use it for Photoshop, Flash, After Effects and 3d studio Max.
I would recommend :
1. Keep your old DDR2 800 CL5 RAM. (If the RAM is still healthy, no need to replace and no need to have more than 4GB).
2. Get an AMD X4 965.
3. Buy an AM2+ mobo with DDR2 compatibility.
4. Get a better GPU if you gonna use the rig for gaming. Let say GTX460, HD5770 or HD6850.
5. For stock speed A.K.A not OCed, just use the stock fan, no need for an after market proc cooler.
