Sims 3 : Screen suddenly goes black when I play game for a while

@srpnizz  First of all, check the connection between the monitor and the computer, on both ends.  In fact, it's a good idea to unplug the cable and inspect it and the plugs for dust, then clean them (compressed air works great) if necessary.  And check the monitor's power cable as well.

If that doesn't help, please run a dxdiag and attach it to a post.

So, I tried clean all plugs and everything but It's still the same.

Here is my information in second solution:

@srpnizz  Do you know how to switch to using onboard graphics?  With some motherboards, it's as simple as plugging the monitor into the board (instead of the graphics card, as you currently have) and restarting the computer.  With other boards, you'd need to boot into BIOS and enable the integrated/onboard graphics first.  If you have no idea how to do this, you can just try plugging the monitor into the motherboard, and if you get no signal even after a restart, plug the monitor back into the graphics card.

My question here is whether the graphics card itself is the cause of the problem, which can be difficult to determine.  The easiest way to test is by using a different card; using the onboard graphics works in the same way.  But if you can't get the integrated graphics chip to work at all, we can put that aside for now.

The other question is whether the game itself is crashing when you have this issue, or whether the cause is something else .  Your dxdiag does list a couple of Sims 3 crashes, but it's not clear when those happened.  So the next time you get a black screen, please look for a corresponding entry in the Reliability Monitor.  Hit Windows key-R and enter "perfmon /rel" without quotes, and you'll see a chart of errors and updates with a column for each day.  Today is on the right.

Look for an error that has a timestamp from exactly when the black screen happened, within a couple of minutes at most.  If you find one, right-click on the error name, select "View technical details," copy the info, and paste it here.  Don't worry if the information is in Thai; I should be able to pick out the relevant details and use a translator where necessary.  Please keep in mind that the Reliability Monitor only updates every hour or so—if you check before launching the game, then get a black screen a few minutes later, you may need to wait an hour to see whether any error was associated with that particular black screen.

I don’t understand anything inside CPU but the last time I change anything inside which I just moved around some plugs and my computer couldn’t turn on so I’m quite afraid to change a thing. 

But as soon as I got the time to open the game, I’ll note every time It crashes and try to do the solution that you’ve suggested. I’ll come back with update, Thank you.

@srpnizz  Just to clarify, you wouldn't be opening up the computer here.  All you'd do is unplug the monitor from the back of the computer and plug it into a different slot.  The graphics card slots are horizontal and about halfway between the top and bottom of the computer; the motherboard slots are vertical and closer to the top.  And if you didn't get a signal, you could switch the monitor cable back to its original plug.

Since you're not comfortable messing with your computer, leave the BIOS part alone for now.  But that doesn't involve opening the case either, just changing some basic settings in the motherboard's software.

So, I played for amost 2 hours and I got black screen again. The thing that I noticed was I my game only crash when live mode but not in build mode or cas.

And here's technical details

OK So, I tried remove package cc and uninstalled sims3pack and It's work! I played for quite a long time without black screen. I'm not sure If it really fixed but I really glad that I can finally play!

Thank you so much
