Hey. I'm new to the boards and I have a question related to a poor old compaq. I know its pretty much junk but I want to make sure. The last six months the cpu has been runing at idle with a temp of 65c. The fan is on constanly. I have already cleaned the tower and is dust free. I check the processes running on it and no cpu intensives are running. I finally decided to check the heat sync to clean and re-apply thermal paste. Now she won't budge. High pitched whine and one slow steady POST beep. Any ideas before I junk it? Compaq Presario S4020WM Athlon 2400 xp
I would recheck the heatsink - see if it's been reinstalled properly. Also, I would reseat the connectors and memory modules.
I've a feeling the heatsink wasn't installed properly, make sure there is a 'click' sound when you install the HSF
