MSI K8N Neo2 Platinum + Athlon 64 3500 Venice. 2 x 512 Mb Crucial\nDDR400 memory(*). Akasa Cooler. New 500W PSU and new SATA Hitachi\ndisk. Using my existing CD/DVD drives & Matrox G550.\nPut it all together and it started up OK. Default BIOS settings apart\nfrom setting the boot HD and disabling IDE. Installed XPPro + SP2.\nHung once during the install but completed OK on rebooting.\nInstalled the drivers off the mobo CD.\nIt stops about 3 - 10 mins after any reboot. No blue screen - just\nfreezes. CPU temp seems OK if I look when booting - c40.\nAlthough I have built many PCs in the past, this is my first AMD one!\nI really have no idea what to try next. Any suggestions would be\ngratefully received!\n\nThanks\n\n* Crucial memory (matched pair) was as recommended for that mobo on\nthe Crucial site although it did say 2.6v on the site and the mobo\nseems to imply 2.5v. They are in DIMM 1 and 3 (the green ones).
