Title: No startup but CPU Fan vibrates Product: Compaq Presario S5000NX PC Desktop with XP Pro Details: After shut-down, start button causes CPU fan to try to start and at times will go full blast for a second then returns to vibrate. Full blast does not last long enough for proper boot. Intermittent problem in that on one occasion machine booted and worked properly after fan worked went full blast. But when placed in sleep-mode and resumed problem on wake-up. Drive lights all work. Power supply light OK.. When fan vibrates, there is a ticking noise as if it is trying to start. Normal startup for this machine is for CPU fan to come on full blast for maybe 10-sec' boot occurs, then fan slows to a quiet running speed. "Full blast" means a high speed with lots of fan noise.
It appears you have a faulty CPU fan and it is causing the CPU to overheat and shut down.
I suggest you replace the CPU fan. remove any dust from the heatsink and put new heatsink compound on the CPU/heatsink.

Any fan that is making noise you would need to replace. There is also never a need to use alcohol to clean a fan. Some computer air or a light wipe down will do just fine.
If you have any other questions let me know.
Thanks,

I don't see how removing the battery would help but tried for the same problem and it did in fact do nothing.
The fan races but the system never makes it to the Bios and never displays anything on the monitor. I suspect a chip is fried on the MoBo.
Maxum52, please post the solution if you found one.

May be your computer motherboard wires connection get loose or getting moisture in wires. Or there may be some earthing problem in ur power switch. First, check the wires connection & tighten up properly. if problem persists, check the earthing by power tester. Check you RAM if it is properly tight in the jack.

Mea Culpa - I should have noted in the question that I did replace the fan and I also removed and cleaned the heatsink and put new compound on the CPU. Heat is not a problem, everything is cool, even that one time when it started and booted properly. It's a real mystery. Thanks for your kind attention.
