I have a windows PII running windows 98 that is giving me problems. I power up the pc and it begins the start up process. Usually when it gets to the window screen it shuts down. Always happens. The fan to the power supply as well as the cpu fan both are running tikk it shuts down. I removed the cpu cleaned any dust away as well as cleaned the power supply. I checked for leaking capacitors and found none. If I leave the machine for a while it will start up but then shuts down again. I can’t get to the bios because it shuts down. Can someone help please..
