Took Vikings to local computer shop to do a diagnosis.
The technician acknowledge the problem I'm facing, so he tried to boot up the computer. First try did not work. The next step he took out the RAM and place it in another slot, reboot. It works.
It's just a simple trick and yet it works. The guy told me the RAM's faulty, and my graphic card is still working though.
It's a relief for me, I do not need to spend any money to fix this up!! :D
Yeah, hopefully this com can stay on like this til I get a replacement someday.....
