Today my computer is always showing a black screen on booting and no signal on monitor, but the monitor is working.
The BIOS message on boot isn't showing up. I thought the problem was my graphics card but it wasn't. I tested by removing the graphics card and tried it with the onboard graphics (VGA, DVI & HDMI). Pulled out the CMOS battery for 10 minutes. I also removed the RAM. Tried every module in every slot alone etc.
CPU, graphics card and tower fan are running. The HDD seems to work because of spin up sound.
Edit: NEW INFO
My computer was turned off for about 30 minutes and now when I boot, everything is working like normal.
What was the the problem?
- GIGABYTE 890GPA-UD3H
- AMD Phenom II X4 945
- 4x 4GB Kingston KVR1333D3N9K2/8G
- NVIDIA GTX460
- Samsung 320GB HDD
I hope you can give me some tips about the possible source of the failure.
