well your jumper is probably set to boot right to bios. you have to go into your comp and move the jumper to its origional location.

Is it SATA or IDE? Have you tried another cable? If it's IDE, have you checked the jumper settings (usually Cable Select is easiest)?

SOURCE: eMachine T6522 monitor says
This could be an issue of a video card gone bad. I have experienced the same issue firsthand. This could also mean that no RAM is installed. If you have been using this computer previously, the second option is probably not even an option.
If you have another computer available, please try plugging the monitor in to that machine to test. If it works, your Video Card is more than likely toast.
But not to worry, you should be able to find a new card for that machine. I believe it will be a PCI Video Card, which may run you anywhere from $20-$100 depending on what you purchase. Please consult with eMachines before ordering a new card. Some will not work with your machine.
I hope this helps you out. Have a great day and please don't hesitate to ask any further questions regarding this issue.

Testimonial: "Will definitely ck this out...sounds possible."
Try this: remove the DMOS battery and unplug the on/off switch plug. It's the one in the corner near the power supply. To be sure follow the cable from the front on/off switch board on back to this plug. Then plug the A/C cord in, if the system boots up fine, then replace the front panel power on/off swith board. Naturally you will not be able to power off the computer using the power switch (since we unplugged it), so you will have to just pull the plug. Hope this helps. Joe

Tips for a great answer:
In your computer (as well as other gadgets), the battery powers a chip called the Real Time Clock (RTC)chip. The RTC is essentially a quartz watch that runs all the time, whether or not the computer has power. The battery powers this clock. When the computer boots up, part of the process is to query the RTC to get the correct time and date. A little quartz clock like this might run for five to seven years off of a small battery. Then it is time to replace the battery.
This does not explain why your computer would not boot, however. You would expect the computer to boot fine but have an incorrect time and date. The reason your computer would not boot is because the RTC chip also contains 64 (or more) bytes of random access memory (RAM). The clock uses 10 bytes of this space, leaving 54 bytes for other purposes. The BIOS stores all sorts of information in the CMOS RAM area, like the number of floppy and hard disk drives, the hard disk drive type, etc. If the CMOS RAM loses power, the computer may not know anything about the hard disk configuration of your machine, and therefore it cannot boot.
Many more modern computers are not quite so dependent on the CMOS RAM. They store the settings innon-volatile RAM that works without any power at all. If the battery goes dead, the clock fails but the computer can still boot using the information in the non-volatile RAM area. I would change the battery and make sure unit is unplugged and my other hand is touching the metal frame on the computer to stop static discharge. Blow out the inside of the computer completely.Start computer with case off and make sure all the fans run and don't sound like a siren.Replace anything not running.It may not boot if the BIOS can't see the hard drives. You might have to start computer and watch the screen and when it asks you to hit a key to get into like the bios do it and see if you can reset it. If nothing seems be running right maybe the power supply went out they are real cheep at Tiger Direct.
