My PC is freezing up a lot recently. Also it fails POST and a long continuous beep is heard and it won't boot. A few times my screen is filled with exclamation marks. I think it might be the CPU overheating as when I open the case and put a desk fan on, it works fine until I switch it off. Sisoftware Sandra tell me that the temperature of the CPU is only 20*C/68*F when the fan is on it but when it locks up at about 26*C. I have a P4 3.0 CPU & I am not running any intensive programs.
Look at the heatsink underneath the CPU fan and make sure it isn't clogged with dust and lint
Mark why won't my laptop work?
