Hello,
I hava a compaq tower that boots up. The fan above the harddrive (i think) spins as fast as i can and all the other fans spin at normal speeds. There is a soild green light above the power in cord input. The computer boots up as soon as i plug it in.
Things i have all ready tried
1. Replaceing the memory cards(or ram sticks dont know what to call them)
2. Holding power butten(that never solves anything)
3. Smelling for burnt smell inside (no burnt smell anywhere.
The computer does not output any signal to the monitor (belive me the monitor works fine)
If anyone can help i will be very happy

Hello,
I would still try to connect to another monitor. If you still have no display, I would suspect that your graphic card has fried.
Regards
P.S. Do you get a display if you boot in safe mode ?

Fans spinning does not equate to "booting up".
If you have speakers attached and you hear the "Windows Start-up" sound then you know it's booted into Windows. The other kind of booting is when it has completed the BIOS booting process. It often gives a single beep when the BIOS has fully booted.
You might try removing the memory modules and see if the BIOS beeps when you try to start the PC. Just unplug the PC from the wall before you remove the memory modules. Absence of beeps might indicate the motherboard or CPU has failed.
Good Luck

Fix/Solved
While the computer is running make sure the cover is off take the lithium battery out of its holder and it should boot up.

The motherboard manufacturers WARN you not to remove the CMOS battery when the computer is plugged in. Just a heads up for anyone that might try this. I would first replace the battery while the computer is unplugged.
