While saving up money for a new computer (so I can play The sims 3), I decided to re-instal all my sims 2 games. While trying to get the sims 3 game to work on my computer(before I relized I had to get a new one), I changed the graphic card, put more memory in, and got a new monitor. BIG MISTAKE! .... When I first turn on the sims 2 game it runs great! until I try to save it, or about a hour into it! Then I get a "out of frequency, HF 23.9 KHz, VF 38.0 HZ, Operating Frequency, 30-90 KHz, 50-160Hz, Power manegment (then counts down from 20)", and then it turns off, and when I turn it back on it says the same thing!!!!. I think its my monitor but Im not sure, I have a LG 900B?. If anyone can help me, I would be for ever in there debt! <3
Thank you very much for your time.

Hi ,

Games run at a different frequency and resolution to your desktop settings . Many of the newer games run at 1024 x 768 , older games tended to use 800 x 600 . I very much doubt it is your monitor at fault .

Firstly try resetting your screen refresh rate to 60 mhz and your screen resolution to 800 x 600 ( lowest screen refresh rate and screen resolution ) then load up Sims 2 and see if you get the same problem .

I had the same problem but not through gaming - I made a dual boot system when trialing Vista running XP at a screen refresh rate of 75 mhz - trying to boot into vista gave the frequency error message . Lowering the screen refresh rate to 60 mhz solved the problem .

Also try installing your correct monitor drivers ( if you've not done so already ) . Here's the link to the driver download for your monitor :

first off let me thank you for reading and taking time out ur life to try and help me! but..I have tryed lowering the refresh rate on my monitor as well as the games refresh rate, and It lets me play abit longer, but still saying the say thing and sreen turning off.
I'm trying to download the proper drivers for my monitor as we speak(from the link you gave me), but its asking me for a register key code to do so? Is there any way around this?
