Greetings all, I have just build a new workstation. WIndows 2000 Pro is installed on a 10000 rpm Seagate Cheetah SCSI drive which commands dual 2.2GHz Xeons mounted on a SuperMicro P4DC6+ with 512MBs pf Corsair RDRAM. Power is supplied by a 475W PCPower and Cooling PS. I have waited quite a while to afford this machine, and as you can see, it is top end beast. What has me talking to myself is its penchant for spontaneous reboots -- sometimes as many as 3 or 4 during an eight hour session. Inital paging size is set to 768 with max set to 1536. I would suspect the power supply, but as you can see, it too is a Lexus-level component -- I realize that anytning piece of equipment could be faulty, even components with reputations such as these. As you can imagine, I don't relish spending anymore money, but I am considering investing in an uninteruptible power supply back up -- in for a penny. in for a pound. But does anyone have any suggestions other than or including this move?
