No signal on monitor
I upgraded my wife's PC to my former PC after I bought a new PC The specs below
I7 975 extreme
16Gb ram
gtx 295 nvidea graphics with latest drivers.
240Gb ssd as C drive
Sometimes 2-3 times a session the monitor goes blank with a No signal message in the box. During this time the Sims 4 audio continues as if teh game continues. Reading over teh net I found similar issues with sims 3 and 4 but no solutions. So far tried
1. 4 different video drivers
2. checked power supply and cpu/motherbord temperatures ( asus probe 2 software running all the time) all ok Power supply 850W thermaltake
3. lowered graphics to absolute lowest settings
4. Testing another graphics card a gtx 9600 a tad low but no issue as yet.2 hrs play.
Any1 seen this issue and have any ideas re a fix. In her old PC a quad 9450 and 8gb ram with a gtx 9800+ card she used to get lock ups which required a reboot now she gets the no signal issue.
PC virus clean that I am sure of.
