manosagn, thanks for your reply. I will check and get back to you on that. However, recently, it hasn't been acting up which is good.
But, my computer now fails to respond when it's inactive for like 10 minutes. I see my monitor is black and when I hit the keys, it doesn't respond. I then have to manually shut it down. If you can help me with this new issue, I'd be indebted to you. Thanks!
