I have a computer with almost the same configuration you describe. P4 2.53GHz, 2 X 512MB 3200 RAM, 160GB WD drive, 120GB WD drive, Sony CDRW, Liteon DVD, ATI 9500 Pro video card, XP Home. To power it all I have a 420W Antec PS (your 300W PS is probably under powered and could be part or all of your problem). I have an Asus P4SDX MB that has never given me a problem. However, I don't know about Canadian availability.

I understand from PC members that ASUS is one of the better boards to use in a computer. Given the specs listed below, can anyone recommend an ASUS mobo that I can buy, preferrably in Canada that will give me good service ?
