I have a computer with a MSI ATX mainboard MS-7037...

Question

Hi I am Richard and I live on the island of Curacao (in the Caribbean).When I start my computer the "on-light" goes on for a minute and then turns out. I do not get signal on my monitor. I hear the computer fans working etc. According to the shop where I brought my computer for repair they checked all parts like power source, processor, videocard etc everything is oke. How can I check the mainboard myself ? or what may be the problem ? Can it be solved this mainboard canot be replaced ?
