The PC Health page in BIOS settins does not list any 12V items at all...
CPU voltage 1,57
AGP voltage 1,50
Chipset voltage 1,60
+5V 4,99
DIMM voltage 2,51
Battery voltage 3,15
5V standby 4,97
It seems that the Speedfan does not recognize all items or at least has different title to them.
Both hard drives (one SATA and one IDE drive) and the CD drive are working ok though.
Last night was again better... no crashes in hour or two of playing.
