I frequently get the computer (Athlon 2000XP 2 x 256 Mgb memory)) switching itself off, black screen than reboot itself, for no apparent reason. Have the same problem after reformatting last weekend. The main fan is pushing out plent air. Would be glad of any suggestions or diagnostics as I only have one week of guarantee left. (
Fine business, gratefull for your help Jester & Mark, checked all 3 fans working nicely (removed dust) temperatures remaining steady. (now 27 board, 46 processor, so cleaning had some effect. Reset 2 sticks of memory (left both in for time being but good idea to remove one later) My computer is self build and all but one memory stick supplied with preassembled board, CPU + fan and memory, local supplier EZ. As long as I can make sensible checks I will have info to help/combat the guarantee claim, that is tomorrow.
