Hi, I built a system for the first time last year, and it closes down spontanously several times a week, which makes it unreliable for trading, which was what I built it for.
I installed a new copy of Window7pro 64 bit onto the new build.
The event logs show several different error types, but I thought I would try to tackle them one by one.
The most persistent seems to be this type, which has just happened:
"A timeout (30000 milliseconds) was reached while waiting for a transaction response from the lmhosts service."
The computer had been idle for about five minutes (it is set to switch off screens after half an hour, and sleep after an hour.)
It spontaneously closed down.
Pressing the power button fired up the fans, but the screens did not come back. So I switched off the rocker power switch on the back of the case then on again, pressed the power button and it started up the fans but again no output to the screens.
Then I held in the power button on the front of the case and pressed it in again and the system rebooted normally.
