ive just built a pc with 6100pm-m2 mobo, 5200 dual core athlon, 8600 1gig geforce gpu with 450 watt psu. it will only work with 1 gig sticks of ram. if i put a 2gig stick in it blue screens as windows is starting. so far ive tried 6 different sticks of 2 gig 5300 ddr2 and it wont have it but does on 2 1gig sticks. i want 4gigs but there is only 2 slots, any ideas?
