Hi everyone, I'm so glad I have found this forum. I have already gone through many of the previous posts and have found them extremely useful. I have tried several things already and hopefully this post will clear out my problem for good. I have just built a desktop. And basically I have been getting the blue screen error since day 1. They seem to appear at random times, I say "they" because I have been getting many different ones. They will show up when I'm listening to music, playing games or even during a clean-installation of Windows (this convinced me that I have a hardware problem). For 2 days I did not get it. But today (the 7th day) I have had 2. So here's what I've tried so far: -Clean installing windows xp pro -Updating drivers (100%) -Speedfan (PSU voltage well within stable range. MOBO temperature slightly high at 50degreesC.) -memtestx86+ (no erros at stock RAM settings) But to no success. I'm leaning towards the motherboard or the graphics card. Here's my computer specs: AMD Athlon64 X2 4200+ DFI Lanparty NF4 Ultra-D ATI radeon x1900gt (sapphire) 1 stick of 1GB RAM (g.skill) 550W PSU (coolmax) Creative Audigy 4 (BSOD appeard even with this card removed) WD SATA 320GB harddrive (OEM, came with nothing, so just plugged it in) Samsung DVD-Writer I post my minidumps here for all the experts out there. Thanks in advance, Hope to hear from you guys soon. HK.
