I just gathered my brothers pc (see sig for specs) and after powering up 3 leds are lit constantly and the 4th are blinking once or twice pr. second. And theres nothing showing on the monitor.
I've tried both sticks of ram in slot 2 & 4, one piece in slot 2, another piece in slot 2 - all to no avail.
Tried clearing the CMOS - only for a few secs though.
Tried disconnecting everything but RAM/CPU/GPU.
All 4 power connectors are plugged in.
Only think i can think of is either faulty motherboard or the PSU is too small.
One thing it also could be, is that the PSU power-plug is only 20 pin (Old standard i guess?) and its a 24 pin hole on the motherboard. Should work anyways though, it does at my own system.
Any tips, hints, guides and so on very much appreciated!
