Re: emachine w2686 no display when boot up
Couple things to check. First, check with different monitor. Their monitors are usually build by KDS and I think there was a bad series out there. Also check for any beep codes through speakers on startup, this can tell you bad ram or bad video out. Also try unplugging computer and removing CMOS battery inside (watch like battery). Lastly, If non of the above, a bad processor will allow the computer to come on but no beep, no boot, no nothing but fans and green power light. Hope this helps a little.....

hi! if your pc is still powering then theres no problem with the PSU, if your pc boot and have a display on your monitor then theres no problem with your VGA card and RAM but if your PC don't have display then you must check your VGA and RAM it maybe a faulty hardware. and next thing you do is check if your HDD is stillworking and make sure you have a bootale CD with you..good luck
It sounds more like the computer isn't starting up. The "no signal" message is coming from the monitor itself to tell you it's on but there's nothing coming in to display. Normally no special drivers are required for the monitor, and you'd see at least the computer maker's splash screen and BIOS messages if the computer was starting up properly.
You'll need to determine what is keeping the computer from starting up. Make sure it's getting AC power and that the power light comes on when you press the front panel power button. You may need a power supply. If the computer comes on but doesn't boot you may have memory problems or trouble with the motherboard. But your monitor is working properly.
Okay if your keyboard doesnt come on, then you shouldnt be able to get past the BIOS screen. Second does the motherboard come with on board VGA??? If so the try sticking a external VGA card in and see if that wont get your screen to work. I know it will cost you, but theres not much you can troubleshoot with a monitor if it wont come on. Oh you can also try booting into safe mode, if you are able to get that far. If you can get into safemode, my bet would be that you have a driver problem.
And how are you able to see that everything else is working if the monitor wont come up???
Anyway give it a bash and see any of this helps. Good luck.
Emachines have had a lot of problems with their power supplies going bad and destroying the motherboard in the process. If you can, start looking for a replacement motherboard (on eBay) and a larger wattage power supply (any local computer store) especially if you have experienced the computer shutting off or rebooting for no apparent reason. If you're lucky, you can try booting into safe mode by pressing the "F8" key on you keyboard during the boot process and select safe mode from the menu. If your computer boots up, then there exist the possibility of a corrupt video driver and/or corrupted file system. If you still can't boot and experience the same thing, then you may have a physical hdd problem or again, power supply, motherboard, or both. Also, do not over look the possibility of an internal fan on the video chip not turning. I hope this helps and good luck.
