Monitors keeps blacking out, flickering but sound & computer working ok. i have tried different monitors but still the same. Thought it might be the video card, i have updated the driver.

I've checked for the video card, seems it's integrated with the ASUS motherboard. it doesn't have any HDMI DV only AVI so must be a cheapy. I ran another monitor for two days and it was ok so I bought another monitor, but then it started blacking out, the monitor arrived next day and i've been using it and yes it's blacking out although not as much, hasn't done it some some hours. me thinks it might be to do with the hot weather, i blown out the dust and the fans are all working and it's a cool day. me thinks i might need to invest and upgrade to a new motherboard and separate video card with a fan etc. Thought this might help others in similar situation.
