Hi, some weeks ago I opened a thread here asking for help with a problem with my new hardware and Windows Vista SP1: http://www.techspot.com/vb/topic107008.html Since I couldn't find the main reason of the failure, I decided to format my hard drive and install windows XP SP3 instead of Vista. It has been working fine for a while, but I've got two BSOD since then, approximately one per week. I write again my system aspects: CPU: Intel Core 2 Quad Q9450 2.6 Ghz FSB 1333 12MB M/b: Gigabyte GA-EX38T-DQ6 Socket 775 RAM: (2x) 1GB Mushkin Extreme XP3-12800 DDR3 1600 GPU: nVidia GeForce 9800 GTX 512MB GDDR3 PCI-e PSU: 750w Aero Cool Horse Power OS: Windows XP SP3 HDD: Samsung 500GB SATA, Seagate 500GB SATA I don't know what has happened. I weren't doing anything at that moment in the computer, and it restarted. I've attached the two minudumps I have. Please, could you download them and tell me what can be the problem? I'm very sad with the new hardware I bought. I'm geting only problems with it, and I don't know why :dead: Of course it was worse with Vista, as I got BSOD several times a day, but I think I shouldn't get any at all. I'll appreciate any help from you. Thanks in advance.
