Dell Inspiron 1520 problems

[picky0nicky]

When I try to start up my computer, it will either flash the Caps Lock light for about 10-15 times, and then shut down. Or it will start up to the first screen for Dell... and not boot up. What could be causing this?? I know very little about computers. I called Dell Support and they told me to replace the motherboard.. does that sound right???

how old is the computer???

is it still under warranty???

Could be a motherboard problem or a power supply problem...
