I rebuilt my PC - installed Asus Extreme Striker mobo, Q6600 Core 2 Quad, dual nVidia 8800GT in sli-configuration, 950W power supply, Vista x64 Home Premium (BTW - great way to get high-end rig. used previous case, Raptor 74x2 HD, CD-R and DVD RW, Audigy 2 ZS Platinum Pro. total cost about $1700). Have installed latest NVidia graphics, nForce mobo drivers and all Vista updates.
Having boot problems: Striker mobo has LCD at back that shows boot sequence. First is "chipinit." Next is "DET DRAM." Boot sequence gets hung up on DET DRAM sometimes but not always. Sometimes simple rebooting works. sometimes I have to unplug the PC for a few minutes and then restart. No overclocking. CPU runs at about 38 deg. C. Any thoughts on what might be the problem?
