Laptop makes screeching noise, then shuts off

Specs: Windows XP SP3
I have a 4 year old Gateway 7246GX laptop that worked fine (more or less) until now. There are 3 problems. When I turn it on, it will make a weird screeching sound that seems to come from the motherboard (?) then it will shut off instantly after about 1 minute of being on the desktop, even if the battery is fully charged. Also, the laptop's fans won't turn on at startup like they usually do. This started happening after it overheated last week and shut off.

The second problem is that the light on the laptop showing the AC adapter is connected will only light up if the battery is in. This happened once before a week and a half ago but seemed to fix itself after 30 minutes, but hasn't fixed itself again and I don't know why.

The 3rd problem is that the DC Jack (or something in/around it inside the laptop) seems to be loose. Even with the battery in, I have to jiggle the plug of the AC Adapter inside the jack to get the power light to turn on. I don't think it's a problem with the AC Adapter itself making electrical contact with the jack, as once I get the jack into the right "position" I can move the plug of the adapter a little and the light will stay on.

All of these things started happening around the same time, last week. I have opened the laptop with a screwdriver to try to see what's wrong, and I know the screeching only happened before that, but I don't know what caused this. Any ideas?

OK, I turned on my laptop and so far it hasn't shut off. I am now posting from the laptop. When it was booting up, I heard the same screeching noise, but only once and it was very short, and it turned on normally. However, the fans still aren't spinning at all, and the DC jack is still loose, I just managed to jiggle it into place and hope it stayed.

Edit: before I turned it on, I held the on button for 2 minutes with the battery and AC adapter out, and plugged the AC adapter into a wall outlet, which I heard about from another thread on here. Seems that worked. :)

Hmm. It seems the fans have started up again. I guess problem solved for now. :)
