Did you find any answer for that? I'm also facing a similar problem. My monitor goes into standby mode the moment I boot up. I had rectified it once from a technician & ended up paying huge amount. After 20 -25 days, the problem again started (I didn't operate my PC for a week).

Now I feel I should do it myself than empty my pocket. There is no beep & the monitor light just blinks. I tested my monitor in other system & it works well.
I also opened up my cpu to figure out about motherboard, bios et al but was scared to do anything wrong. I'm not a hardware person but wish to know the details of this problem.

Please help!!

Thanks,
Jas

There is no beep & the monitor light just blinks. I tested my monitor in other system & it works well.

"No beep" almost 100% indicates a hardware problem with the computer. The mionitor is going to sleep because it's not gettting a signal. How old is the computer? Do the fans spin up? The hard drives? How about the front paned LEDs? The CD-ROM LED? There are many things that could cause this sort of problem.

That's too broad a scope for simple answers here to address. Google is your friend.

www.google.com

Don't use one word search criteria. Use terms like 'What is a motherboard' or 'how does a motherboard work' 'What does BIOS do' 'How do I change BIOS settings'

You'll uncover articles and discussions, and the best thing you can do is read, read, read.


Your motherboard basically is your computer, and the BIOS is the chip on it which contains code to let every little part of it find and interact with the rest. That's a pretty big field you're walking into there!
