Just put a system together... Asus P5W DH Deluxe E6600 Conroe Kingwin 600 watt mach 1 ATI X1650 pro OCZ memory 2 gigs Rosewill CPU heatsink I was originally told by my dads friend (im staying at his house) that the outlets in my room were 230V. I was having problems with the motherboard posting. at first I thought it was the motherboard itsself, so i took it into a computer tech and he said the mobo was bad. I replaced the mobo, mind you, still thinking the outlets were 230's, and tried the other one and the same thing. NOW, i have been informed that the outlets are only 115V. I took out the battery on the mobo, reset the cmos, reseated the memory, disconnected everything from the PSU and plugged it all back in. THEN i set the PSU to 115 before I powered it on. The fans power on, mobo light come on, hard drive spins, cd drive works, everything works great except the mobo still wont post. (monitor has been tested and works too) my question is, would having the PSU set to 230 instead of 115 ruin anything else besides the Power supply itself? like the mobo or conroe? if not then it would be the PSU i would need to replace in order to get my mobo to post correct?
