Hi, sometimes when i play a game my monitor says it has no signal but i can still hear the game still running through the speakers.
I have a Sapphire Ultimate 4670 512mb, Thermaltake TR2 RX 500 PSU, Dell 2209wa monitor, 1tb hdd and 500gb hdd, 1 optical drive, 2gb ddr2 ram and athlon 64 x2 4200. I realize this isn't the most powerful system but should be more than enough for Age of empires 3 and The Sims 3(at least i hope)

I have just updated the ATI drivers to 9.6 tried with driver only and with full CCC but the problem remains unchanged.
My case is getting plenty of airflow and temps are good.
Using Windows XP 32bit sp3 genuine fully updated.

This has been happening for months and have not been able to fix it.

Does anyone have any ideas, any help would be appreciated

part of me is thinking this is a PSU problem but i don't want to spend money on one if it's not

I don't think it will be a PSU problem, 500W is more than enough to power your system. I'm guessing its either a problem with your graphics card or monitor.

Thank you for replying
i have just recently tried Sims 3 again this time in windowed mode at 1024x768 and it ran good for over an hour until it lost signal and i had to restart, would this imply it's a problem with the graphics card?

it's your monitor problem,you should change your monitor.i had this problem with my 15" crt monitor because my monitor doesn't support refresh rate above 60hz if i change resolution above 800*600

chek your vga temp maybe it's too high. i think ultimate is passive cooling version(i'm not sure) try to add a 90 mm fan on your vga heatsink

I ran GPU-Z while playing and here is a minutes worth of readings until it went

strange stuff at the bottom, hopefully it will shed more light on the cause

Edit: yes it is a passive card, why it shows fan speed i have no idea.
also this time when i had to restart the color quality changed itself to 16bit instead of 32bit
