i hear a click from the monitor upon powering up but it's indicator light almost immediarely goes from yellow to amber (orange?), the cpu appears to boot up as usual but there's no display whatsoever - i suspect it's a hardware thing (monitor), f.y.i. i'm unable to get to monitor to "wake up"

I was in your problem 2 days ago, and the VGA card was not connected proparly, I opened the case, connect the Display adapter well and start, and hey everything is going to work again.

It sounds like your computer is not really running.    Try getting into the BIOS setting, then plug the monitor into both ports. \n\nIf this does not work, then use the CLEAR CMOS jumper on the Motherboard.  I did have issues with my ASUS motherboard, and this was THE CURE. \n\nGood Luck

I would guess the power supply failed.\nIf the hard drive spins up and you can tell it is booting up you may have a bad video card or a bad monitor.

Somethings to do will be;\n\nOpen the computer and check all cables and connections\nRemove the CMOS battery to reset the Bios\nDisconnect any hardware that you don't need to boot up\nTake the Ram out and then put it back in\n\nIf none of this helps then it is either a power supply problem or the CPU is blown and the only way to find out which one is to remove it and test it with a working one.

normally if you have a yellow led, as the monitor says it's in standby mode.\n\nIf you have just turned your computer on and the monitor does not change from the standby mode then check:\n\n1) Your vga cable from your monitor is firmly in the back of the pc.\n\n2) Try your monitor on a different computer - see if you get the same results.\n\n2) Try installing a new video card on your computer. Do this only if 1 or 2 does not work.\n\nA lot of the time the reason the monitor does not turn on is because usually the motherboard has died or the graphic card has died.

No signal means your monitor is not going on. If when you turn your computer on, you can hear the hard drive come on and boot, it is not the power supply, probably a video card issue. If when you turn it on and the fan runs for a second and then dies it is the power supply.

I think every thing is OK.\nIf you see nothing on monitor than reinstall the AGP Card, RAMs  into the motherboard. \nCheck each connections into the motherboard and reinstall Windows. \nHope it will solve the problem other wise you will have to visit a technician.\nGood Luck!

My best guess is a dead hard drive.  Does the computer make it past the Post (power on self test) screen.  Does it attempt to load Windows, does the clicking start with HD access or does it start as soon as you turn the PC on.  Is anything displayed on the screen at all... until the clicking starts.  If your computer makes it past Post then I'm going with my initial gut feeling that your hard drive died on you.\n\nOf course, I've never had a motherboard short out on me so I have no idea what that would sound like... but it could be, I couldn't say.  Once again, this is one of these catch all problems where just about anything mechanical or electronic could be causing the noise.\n\nWell, since nothing works, this is going to be hard to diagnose.  Best guess is still a hard drive but now I'm going to toss in the processor, memory, GPU and well, any other hardware in your system.  Start removing components one by one and see what happens, save for the processor, I've never tried to boot a system without a processor but my guess is nothing will happen.  If that doesn't work, you're right back at square one.  Here's an idea, take your hard drive out, plug it into another computer as a slave and see if it at least works, don't do anything to it, just see if it is recognized, if it is, not the hard drive.  If you can rule out the hard drive you are looking at a dead motherboard and/or processor which will have to be replaced at least.  If the motherboard is fried, you'll have to check the other components to see what is good and what is not.

When does it get blurry, as soon as you turn on the pc and it says windows xp, or when you access the desktop, or when veiwing movies, etc. \n** Are you familiar with accessing your computers bios? If the screen is blurry when your in the bios then the problem is not the OS video drivers**\nWhats the make and model of the monitor? there may me a recall on it. Take that info (make and model) and check on the manufacturers website. If you really don't want to go through all that, and you bought it from a local retail store recently (like within a 1 week time frame), then bring it back there and have them test it. If it works at the store then it might be something wrong with the pc video card.

Your display adapter my be moved a little bit, open the case and check if it is fully connected to the mainboard.

You mean everything? BIOS just woldn't come up? There is no way to fix that unless you send it in to the maker of the BIOS or where you bought your ocmptuer so they can fiz it.

Its got a bios setup....you need to watch the screen when it boots....at some point it will tell you what key to press....it may be quick so keep your eyes peeled! Usually its the delete key

It sounds like your hard drive is getting ready to go.  My suggestion is to get your system backed up, either with an external USB hard drive or a tape drive, if you're not backing it up already, because it sound like you'll need to replace your hard drive soon.  Usually when you get the black screen with reboot information on it the hard drive is having a hard time reading the boot information/operating system information from the disk.  I also would just leave the system on for the time being because next time it may not boot up at all.

well it may have the power settings to turn off monitor after a short period, start it up again, lay on the F-8 key to go into Safe mode,,,, and you can check the settings for the power down on the monitor,  Otherwise,,, if you had System restore activated while your in safe mode you should be able to restore to previous point,  Otherwise,,  if you have a brand name laptop Dell, HP, etc If you dont have the factory restore discs I would call them and ask for some, I bought a used Dell 2 months ago, no restore discs came with it, I contacted them online and they sent me new ones, if you dont have a brand name laptop, then you may need to have a full version, since you mention it "Formats" ,  But also you need to have the drivers for your CD Rom on the disc otherwise the CD Rom wont have anyway to continue on and read the disc you put in there for it to read,,,   If you dont have a disc with a bootable version, IM or E-M me and I can maybe help you out,

Check the battery..Go buy a new Battery.. See if it boots up then..If it dosent then it looks like a computer doctor is needed.Could be costly. If its an old one. it might pay you go buy a newer one.

1.check your power cord for the computer\n2.try plugging it into a different electric plugin place\n3.make sure the power supply fan is running on back of the CPU tower
