Normally when I press the main switch the computer will have a “beep” sound and then the boot up screen will show on the monitor. But recently when I pressed the main switch my computer has no response.
I am sure there is electricity on my computer because the fan is running and I am able to open my CD-Rom.
I have changed another power supply (230v) and video card but it still doesn’t work. In order to test the hard disk, I put it on my friend’s computer and it works fine.
Indeed, my computer was like this in the past few weeks, but I was still able to switch it on after 5 to 6 attempts. However, I can not switch it on anymore no matter how many times I tried now…
I think the problem is the motherboard but I am not so sure. Could anyone please give me some advice…many thanks!!
