Well as you have already tried disconnecting the peripherals from your computer, and tried restarting the computer too which did not help you, it sounds to be an hardware issue with the monitor. However if incase you have not tried this, you can disconnect the monitor completely from the tower, power on the monitor, if it powers on and you get a message as no signal, your monitor is working good. If not replace the monitor. If the message appears on the monitor screen, disconnect everything from the tower, push and hold the power button on the tower for a minute. Connect just the monitor and check for any display. If you do get display, thats good, connect one device at a time and check to see if the display appears.
If theres no display with just the monitor connected, the issue would be with the graphics card. You may need to replace it or get the system repaired.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

Your new moniter may not be compatible with your computer. I have an Emachines that won't take a flat screen. I have to use a big bulky moniter because it says not connected even thought the hookup fits the back of the tower. That might be your problem. Did your old moniter work correctly?
First make sure that all the cords are connected properly from the back of the CPU to your Monitor.I suggest you to unplug all the cords of the CPU and then plug them back in after 10min. and make sure they are all connected tightly.Next check if the power cord connected to the Monitor is attached tightly.
If you still face the problem then you will have to replace it with a new power cord whih connects the CPU to your Monitor.It is black in colour.
Try plugging in headphones into your computer. If they work then your audio circuit is working. You can also try running the diagnostics from the the Resource CD, It will have"Diagnostics and utilities" listed under the "Contents". You will have to bootfrom that CD disk. To do this, power on your computer and tap the keyto bring you to the "One time boot menu". Insert the CD and then select CD/DVDdrive and hit key. Selectthe "Run the 32 Bit Dell Diagnostics". Select "Custom Tests" and run the audiotest. If the audio tests fail you might have a problem with your speakers. The easiest and sure fire way to determine if your speakers are the problem is to try another set of speakers.
The original CPU was 1200 Mhz, namely 12 times the 100 Mhz "clocking" supplied by the motherboard.
The new CPU is 1.53 Mhz, namely 11.5 times a 133 Mhz clocking, if the motherboard can supply that rate of clocking.
If your motherboard can only supply 100 Mhz clocking,
then the new CPU would run at 1150 Mhz (namely its 11.5 multiplier over the 100 Mhz clocking), i.e., slower than the original CPU.
Can you try the 1.2 processor in some other motherboard?
It's possible that you "killed" it, when you removed it,
or after you removed it, by giving it a static-electricity burst.
Do you have another processor that you can try in your motherboard?
What happens if you put the 1.53 processor into the motherboard?
Does it POST (Power On Self Test) ?
the light blinking makes me think that the moniter is going in to sleep mode...try turning the computer on while the moniter is not pluged in(pull the blue vga cable) wait a bit then move the mouse around then plug the vga coble back in...(while the screen is already on)
First of all you need a sound card on your computer with a Spk. (Speaker) or Phones (headphones) Out Jack it might be a symbol of a small speaker or headphones. You have to be sure you are getting a actual sound output signal from this sound card too. If the sound card is not working your moniter speakers would not have a signal to drive it. You also need a 1/8" Stereo 2 male stereo plugs on both ends, one end plugs in back of moniter other plugs in back of computer like I mentiond above. Make sure your Mute button is not selected on your computers volume button usally at bottom right of screen. Make sure the volume buttons are up to aprox 3/4 up also. Then for last on the moniter look in the menu i think you might have to keep pressing the menu button but i kind of forget now but its a Spk setting and volume setting in this speaker setup within the moniter as well make sure this is turned on and set at a higher volume level as well. Thats about all I can say without taking the moniter apart and checking the jack and wires and speakers. I would suggest you take it to a electronics or a tv repair or computer repair person to go any further then this. Hope you take time to read all of this I tried to put every step in here to help anyone out with this problem. Thanks for reading.
