How to hook up a pc computer

It might be in a corrupted hybernation mode.
Try turning the computer off by pushing the power button for 10 seconds and then do not choose resume but the other option.

what tower? model, the monitor has nothing to do with power and dead fans in the tower.
'Sounds, (and silent to) means the PLUS in the PC is dead.
all things can be repaired, that is what technicians do.
here is the chain of events, ! to get noise (fans)
power in the wall 120vac , usa
power to the PSU,
the power button goes to the MOBO, and standby power is there
now and pushing said button the MOBO commands the PSU on
if the PSU is happy (PWROK) thinks PSU IS safe the PSU tells the PC its ok, and power stays up.
and fans run.

so my guess bad PSU, its easy to test with anyf $10 voltmeter,
ask.

tower PSU, 101

Look for a setup guide here: http://www.dell.com/us/dfh/p/studio-slim/pd

The manual for your speakers can be found at http://www.logitech.com/repository/1411/pdf/27251.1.0.pdf. The Speakers should be conected to your computer as opposed to the moniter. Disconect the small wire from the moniter to the computer and insert the plug from the speakers where it came from.

Phone jack on woofer goes into computer tower (should be color coded green) and power cable on woofer plugs into 120VAC. Speaker phone jack plugs into back of woofer. The speaker cable has an on-off switch and volume control as well as a phone jack for your headset.

its is telling you the truth (99.9999999% of the time)
believe it !

no PC stated
no TV model stated nor clear connections stated.
are you trying to get the PC (the tower means that)?
to run to video concurrent ports at the same time?

so do both fail,
VGA side
and DVI side,
you never said.

hard to help lacking
what TV
what Tower
what connections, and special adapter (HDMI)
the TV has DVI??
sorry, cant see what you have there. at all.

it means that the monitor is not receiving any signal from the cpu, check the cable that goes from the tower (cpu) to the monitor

It sounds as if your power supply is having issues, I would recommend replacing it.  If your good with computers, you can test the power supply: 1. Open the computer tower. 2. Find the main plug which runs from the power supply to the motherboard. 3. There should be 16 wires. 4. Find the green wire, short it to the black wire with a paper clip. 5. If the computer seems to turn on, its your motherboard having issues and you will probably need a new computer.  If it does not turn on, your power supply has failed, and you need to replace it.
I hope this helps!

on the back of the tower, there are 3 jacks colored Red Green and Blue, the speakers plug into the Green Jack

Hi Brenda,

Your All In One wants a phone line hooked directly to it. It won't fax without a "POTS" line directly hooked to it. POTS stands for "Plain Old Telephone Service" which is the line with good old dial tone on it.
