For a couple of weeks now, my CPU alarm has been going off. I dealt with it by closing programs and putting a big fan against the back of the tower, blowing air into it. When the alarm went off, I closed programs and turned up the fan to high. A couple weeks of that, and I decided to take the tower in to the shop. He replaced the CPU fan on the guess that that was what was causing the problem, but then when he tried to reboot, he got a memory error (checking memory). This went on for 20 minutes or so and the only way to get out of it was to swap out one of the memory sticks, which he assumed had gone bad. So now I am running on only 512 MB of memory, which kind of sucks, but I use Windows 2000, and that uses memory very well and requires very little.
Anyway, with the “bad memory” swapped out and the new CPU fan in, I took it home and started it up. It immediately started checking memory again, and started looping around on that. I hit escape to get out of that mouse wheel. Then it booted up. But after a bit, the CPU alarm went off again! So replacing the CPU fan did not end any of the problems associated with overheating.
What’s going on? Why is the motherboard overheating. How come changing the CPU fan did not stop the problem? Why did the memory stick suddenly die, if it even did? Why is the computer still running endless memory checks with seemingly good memory in the box?
I am not understanding so many things here.
