I honestly didn't know where to put this question...I think there's numerous problems...so I put it here. If its in the wrong place- sorry, I'm new here.
So I've been abroad for several months now- I have a T60, IBM Thinkpad. I've had it about three YEARS now. I downloaded skype before studying abroad which made the computer a little slow but no worries. A few months ago it sounded like the computer was HUMMING. Like the fan was REALLY loud. It has been that way for a long time now. Today, (I know it sounds crazy, but I swear its true) I heard a FAINT chirping noise and thought it was a bird outside or something until I realized it was coming from the computer. I put it on sleep and started it later, but the noise only lasted a few minutes before it went away again. The humming fan is still going.
Even more recently, a little sign came up in the right hand corner saying: Low virtual memory. I spent most of last night getting rid of old pictures, and stuff and emptying the recycling bin.
Went to a computer help SHOP. They want to remove McAfee and other antivirus programs. They want to remove a bunch of other stuff from my laptop as well. I do not know what they have in mind. They never said. They also want me to look at a hard drive as a backup device. And lastly they want to check the fan on my computer.
Does this sound reasonable? Does anybody have any advice of what I can do to fix my own computer? Any advice on whats causing the humming or chirping?
Thank you!The chirping/humming and low virtual memory error messages tend to lead me to one culprit here...
The hard drive is probably getting ready to fail.

To determine this find out in your manual or at the laptop manuf. site what brand drive is in there...
Then travel to the HDD manuf. site and DLoad and run the FREE diagnostics on that hard drive.
This will tell you if in fact this is the issue. Run the long test. It takes awhile so do it at bedtime and let it run til it finishes.
The less you can use the machine in the meantime the better...there are methods where you can replace the drive (not too costly) and save all your data before failure OCCURS but let's find out first if this is the issue.

Report back with the results and again try to use it as little as possible til we know...Plus, it also sounds like you are running more than one anti-virus at once...this is a very bad idea as it causes performance issues, and also some certain type conflict with each other.
