Hi, my system is less than 2 months old, and has BSOD'd on wake up pretty much every day since I built it.
The test I have run so far;
Western digital hard drive diagnostic; pass
Amd athlon II x4 630
gigabyte 880gm-ud2h Mobo (latest bios revision)
ati radeon hd 5770 (his cooler)
western digital caviar black 1tb
4gb corsair ddr3 1333
Bfg gs 550 watt psu
windows 7 ultimate 64 bit
The frequency of bsod had diminished slightly after the bios update, if that matters.
Thanks in advance to the kind soul who chooses this post to read.
