Question about PC Desktops
When I boot up my computer the Monitor says no signal, The computer lights are on.I turn the power strip off.The computer and Monitor turn off and then I turn the power strip back on and the Monitor and Computer turn on with out a problem.Sometimes I have to do the above 2 or 3 times.This only happens in the morning when I boot up my system.I think its a Computer problem and not a Monitor problem, The same thing happens when I had my old CRT Monitor hooked up.Can you please tell me what the problem is?Thank You
Is this a brand new system? What is the make/model?
This is a peculiar problem, as the computer was working fine for several months after you purchased the computer, then suddenly started this behavior. The fact that you do establish normal operation after the restart eliminates a few culprits. Your monitor is perfectly fine, as you eliminated that by trying another (same problem). I doubt the problem is your BIOS, as the OEM BIOS is usually a very solid part of the system. Unless you updated it in March/April?
The hardware should be fine--if there's a hardware problem, usually it works or doesn't work, or will work intermittently in an unpredictable manner (meaning, you'd start up and everything would be fine, but later on the video would cut out).
Also, try this experiment: When you start up the computer and you get the "no signal" indicator on the monitor, shut down the computer and leave it off for about 5 minutes. Start it again. If the problem repeats, it could be that there's some kind of software conflict between the operating system and BIOS, but a warm restart bypasses this.
It is possible that a Windows update that occurred around March/April may be conflicting with a driver or the BIOS. There are a couple of things you can try... In the "Accessories > System Tools" there is a System Restore utility. If you haven't made many changes to your system since March/April (e.g. installed a lot of device drivers, components, software), you could try restoring to a point where you are certain the problem wasn't occuring. If that works, you know that a software update is the culprit. If it doesn't, don't worry--you can "undo" the restore and go back to where you were so you don't lose other things you've installed (your registry gets updated frequently over time and you don't want to lose that).
There may be an updated BIOS for your computer as well. If you bought it new, it doesn't guarantee they had the latest installed when you got it.

You should try resetting the BIOS (either by changing the right jumper, or by pulling out the CMOS battery, or whatever religious ritual your brand of motherboard requires, such as sacrificing a chicken on the keyboard), because it sounds like you've got a problem with one of the busses (e.g. the PCI bus, the AGP bus, the Chicago-bound Bus, or whatever). It may only be a software problem, which you might be able to get rid of by resetting the BIOS; but if your computer still displays the same vital signs as an ashtray, then you've got a more serious problem on your hands. Post back here and we'll see then.

Tips for a great answer:
you plug in the power cord is there any lights whatsoever on the laptop, where
the plug goes in or on the AC Adapter of the power cord?
When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the computer is trying to boot or may have booted, but the screen is not showing for some reason.
Beep tones and blinking lights tells the technicians what is going on with the laptop and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).
Maybe you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.
your memory is bad or the memory slot is bad.
the Power Cord, Open the Case and remove one of the memory chips. Set the
chip aside then try rebooting the computer. If it boots, then you know
the memory chip you set aside is bad so mark an x on it with an ink pen.
If it fails to boot then move the chip to the next memory slot and try
rebooting. If it fails take the chip out and set it aside, then put the
other chip in and try booting it in both slots. If it boots, just to
verify that the chip set aside is bad, mark an x on it and put it into the open
memory chip slot and try booting.
