sims2 not working with LCD monitor

i have sims 2 i used to work fine with my old monitor but my step dad brute a new lcd monitor now en i play sims 2 the monitor cuts out saying no signal it dos this with both analog and digital more often with digital but it dosent happen with any other game and it i tride turning the garffics down and it steal dosent work
(ps sory for bad speling)

 

I use a huge 31" LCD Screen. But it can not take more than 1024x768. It says signal lost if i increase the resolution. Maybe you have the same problem.

 

thanx hope that works cos i love the game but it anoys me how it cuts out all the time

 

What video card do you have, and do you have the latest Direct x installed?

 

i woldent have a clue what vido card i have but its a prty carp 1 im gesing thats me prob cos turing the resalushon down dosent work and i think i got direct X 9

Try checking if you PC's earthing is proper. (ie) do you feel any shock when you run your comp for a long time?If so then it would really damage your system. Or just check the basics, if you have plugged in the VGA plug properly, lose connecting could be the problem

 

english is my first langiwich i just dident lern much in school

 

i dont thnk its the earth plug thing cos i dont have much other probloms with my computer ic sept for the problom with simes it doentdo it with any other game

 

Does it switch off only when you play sims or just in general

 

the monitor only cuts out with sims not with any other thing on my computer
