Some parts of the PC are new ...
MB - Gigabyte GA-MA770T-UD3 AMD 770 Socket AM3 8 Channel Audio
CPU - AMD Athlon II X2 250 Socket AM3 3.0GHz 2MB L2 Cache
CPU Fan - standard fan that came with the CPU
RAM - 1 stick of Crucial 2GB DDR3 1333MHz/PC3-10600 CL9 1.5V
LG DVD
Older parts are ...
PSU - Coloursit 600W PFC 20 + 4 Pin
Graphics Card - PNY GeForce 7300 GS 256GB DDR2 PCI Express
HD - Maxtor Diamond Max 160GB IDE
Standard keyboard
USB Optical mouse
I also have 3 other internal hard drives (one IDE and two SATA), two external hard drives, printer, a couple of case fans.
I have everything unplugged at the moment except the boot disc, graphics card and keyboard. I've also tried it without the keyboard and with two other keyboards I have, one with the purple connector and one USB wireless.
I've tested 2 mice.
I've tried the PSU in my old PC, that seems to work fine, although the old PC works fine with a 250W PSU so that isn't really testing the 600W one at the same load.
At this point I guess I'll be sending the MB and CPU back for a check over - unless there is anything else anyone can suggest !
Thanks,
Galli.
