When I got home to install the LCD screen could not boot up. I called Moni and discovered that I had to use a DVI cable or to use a DVI adapter. That damn Moni did not tell me earlier and I had to go to Sunway to buy that piece of adapter.
Again, as I got back the PC wouldn't boot and as I tried to reboot the plastic button got stuck. Again, I had to sent it back to Moni. This time the PC doctor said it could be due to the DVD player. I am not sure but I decide to change a new Samsung DVD player which is only $100.
The test was done and it works. I thought I might as well buy a new wireless keyboard and mouse to replace my existing one which is also a wireless set. After all, it was about spending money and maybe spending some money will heal the problem. It did! The problem is resolved and I can now do my blogging.
