Help me please, My 330W Antec PSU blew up the other day. I replaced the PSU but now the pc won't get to the POST screen. The monitor works ok and with power to the gcard I can see text ok but the screen just displays processor as 1100Mhz and RAM as 1Gb. I have an Athlon 2500 Barton and Corsair RAM. I think the PSU may have blown something on the motherboard. Any ideas?
