Is 330w enough? Not that we can go on the wattage, the current the psu can supply seems to be an issue. Might need a bit more juice. Most responses I've read elsewhere seem to fixed by a decent psu. Strange thing is, I get the not receiving signal message on the monitor but when powered up It briefly goes dark as though its about to boot but then returns to the same message. Anyway, I'll have to wait and see what the man in shop says tomorrow !!
