Sony Vaio Desktop - Suddenly Died

Hello Forum Friends!

I have a Sony Vaio PCV - RS422. The compute is over two years old and out of warranty. Last Sunday, I noticed that the screen saver was frozen. After trying for a while, I did what had worked in the past - did a hard boot.

However, after starting the computer again, I did not get any activity on the monitor screen at all - no Sony splash screen, no DOS screen, no OS screen - NOTHING AT ALL. I tried booting it again, leaving it shut off unplugged from power overnight and then trying it again etc. but nothing worked.

I have checked the monitor and its power cord - they are working fine with my other desktop.

Before I take it over to Circuit City or Best Buy to get professional help, I was hoping if some on this forum can provide any insight or tricks that may help me rule out whether the problem is failed hard drive or something else.

Any and / or all help will be appreciated.

Thanks,
