Sounds like the graphics card maybe bad.
Does your computer have a onboard VGA monitor connection? If so you could remove the graphics card and hook up the monitor as VGA and see if that works.
If it does then it's a bad graphics card and needs to be replaced....Sounds like it still should be under warranty.
The higher fan noise could be the fan on the graphics card not a computer fan.
hello,
I'm afraid i really don't know much about computers so please humour my humble approach to explaining this problem i have.
I recently bought a computer and I had no problems up untill yesterday when my comp decided to stop sending a signal to the monitor (i've checked monitor on other devices and it works fine).
There are 2 'dvi' connections and a hdmi in the back of my computer. ive tried each of these to no avail.
I can hear my computer boot up but not see anything. (The only difference being the computer fan is louder than usual)
Is there any way i can see whats actually happening?
Any ideas would be warmly welcomed, thanks in advance.
im running win 7 pro 64 on an Intel Z68x-ud5 i7 with a raedon6970 card.
