Specs: Biostar TA760G AM2+ X3 440 2 x 2GB DDR2 667 + 2 x 1GB DDR2 667 - All Crucial sets TT Mini Typhoon 1 x 80GB IDE for OS 1 x 640GB + 2 x 500GB RAID0 to host VMs Host OS W2K3 Standard 64bit Antec 430w Trio PSU And a regular good airflow mATX case that really gets dusty lol. And ofcourse 2 fans to keep the airflow. Have the version just prior to the latest bios. Problems: Out of no where the system will go blank while booting or system is idle. The watt meter generally shows up 76w on idle but when it goes blank it shows 44w. The system is not responding until you press the reset button (sometimes need couple of times resetting) If the system is properly shutdown and PSU switch is turned off, leave for a minute or so, turn it on all fans comes up, the fan speed is not throttled by the mobo, no hdd lights until I press reset button, then the fans will throttle down and the mobo will start the boot sequence. All settings are default, CPU is not overclocked, no unlocking, Ram as per specs. This is a server so no fiddling with those things. I reset the Cmos jumper and still it does the same thing. Was running fine for almost 3 months 24/7. I am thinking its the Cmos battery that is dying. Any other thoughts? Hope the mobo is not dying. I reset the PC last night and this morning there was no response, so once again turned off and turned it on, hit the reset button and its been working since then for about 4 hrs now. I checked the cmos/OS date and time and it didn't change. And oh the NB freq and HT freq needs to set at 1600 Mhz rather than 2000 Mhz, if I let it auto or more than 1600 Mhz the system becomes unstable. Help please.
