I’ve tried two almost complete systems and neither will boot.
#1 = AMD A6-3650 APU, Gigabyte A75M D2H m/b, G.skill Ripjaws 2x4G F3-12800CL9D-8GBRL. Connected to monitor. Would not power up – no beeps or anything. Tested power supply – was OK. Even tried different power supply. Removed everything from enclosure – still no luck. Tried with only one memory stick.
#2 – Without installing in enclosure tried new motherboard (same type), with new AMD A4-3400, and both one memory and both memories. Still won’t power up.
Please tell me where I went wrong; here’s what we did:
1. installed APU and cooling fan (double checked for correct fit).
2. Connected ATX 12V and 24 apin connector
3. connected CPU fan plug (4 pin)
4. Installed memory – when used 1 installed nearest 24 pin.
5. Turned on power supply.
Have checked CPU requirements for motherboard and memory requirements, too.
Think we must be doing something wrong, but not sure how to trouble shoot from here.
