I've been trying to build a media pc with a bunch of old parts that have been sitting in boxes unused since 2008
ASUS A8N32 SLI Motherboard
AMD 4200 X2 CPU
Hynix 1GB DDR400 x2
Have also got a new Gigabyte 5450 fanless gfx card, and some old IDE hard drives.
The PSU i'm using is a Corsair HX650 which is only about 6 months old, and is in working order since I tested it in my current PC.
Now the problem I have is that the green power light comes on the motherboard, hard drives start spinning, but the CPU fan just doesn't seem to be going full speed and subsequently the computer does not want to boot, or bring up BIOS or anything on the display.
I don't have a PC speaker in this case so I can't work out if there are any beeps or not.
If i disconnect the 4 pin 12v ATX power to the motherboard and power on, the CPU fan goes at full speed except obviously it won't boot without the 12v cable from the PSU plugged in. I've also tried removing all the other components but still no success.
My thoughts are that since the motherboard and CPU have been sitting for ages un-used, the thermal grease might have dried up or the CPU isn't sitting correctly? I don't have any thermal grease but i'm thinking i might clean the contacts, apply some more and resit the CPU on the motherboard with the heatseak & fan.
Does anyone have any suggestions or other thoughts to what it might be?
