Does this happen when you set the monitor to sleep? Sometimes I don't get a signal to my monitor after it would go into sleep mode. I set it so it never goes into sleep mode again so I don't have a problem with it now.

i think that's not my problem, because sometimes when i just turn on my pc(usually i turn off my monitor too), the monitor often get no signal from my graphic card

maybe you have a faulty monitor connector? that blue thing that connects to your video card?

i don't touch that thing.
first it think that's the problem, but i try to release the cable and put it in the proper place, but my monitor still doesn't get any signal

Maybe a dodgy VGA cable?

Try wiggling it around and see if it flickers back on.

not that too.
i've try to change monitor, but it's still no signal

Do you get any beeps when you turn the computer on? If not then you might try taking your video card out and putting it back in again. If that doesn't fix it then you probably have a bad video card. I would try another card and see if it works. If still nothing then you probably have a bad mobo and need to get a new one.

ahhh... i think i'll take it to the service centre now. i'm already tired with this problem. thanks for helping me

it may be a some electric shock, or lack off power :P radeon uses a lot of it, so if you got only 300W it may be the problem

thanks for the help, i'll try to change my power supply
