Windows 10: Power light on but no boot

This has gone from bad to worse. It started with an error message when I went to close down, to the effect that the Start Button wasn't working and would reset on restart. I restarted; it didn't reset. I could use programs but the Start button still wouldn't work. I tried to restart in Safe Mode, but the computer wouldn't go into Safe Mode -- I got the screens that let me select reset but the final step that would select Safe Mode with Networking just got skipped. I'm a little sketchy on what I did next (I got kind of and had to step away from the computer for about a week to cool off, and I'm afraid I didn't write out a history while it was still fresh in my mind) but I tried a variety of things to force it to start in Safe Mode and the result is that it doesn't start at all now: the power light comes on, but the screen stays blank and there's no action on the drives.
Should I use my laptop to create a USB Recovery Drive to start the desktop computer on?

windows 10 fails to boot

after updating to 10 computer will not turn on and boot. Power light and hard drive light comes on briefly then goes off.

 

PC Boot but no display.

Yes, I did but no changes.

 

Does it beep on boot? After you turn it on before windows loads (or tries to load) do you hear a beep to confirm your bios has posted?

 

No beep -- all that happens is the fan comes on.

 

mmmmm there is a possibility it has no speaker installed have you heard it beep in the past? If so let me know make and model of motherboard and ill tell you how to clear your cmos

 

I have external speakers connected -- they work fine because I've been using them with my laptop, too. How do I ID the model of motherboard? I've taken the cover off the front, but don't see any identifying info on the motherboard itself.

 

Do any of these numbers look like Models?
E145B3
MS1003
MIB75R/MH_SG MLK MB
11068-1
48.3HD01.011

 

This is what I'm looking at: http://i42.tinypic.com/2144k5i.jpg
I'm not sure where to locate the motherboard model #.

 

I located instructions for resetting CMOS (Clearing Cmos Passwords - Dell Inspiron 660 Owner's Manual [Page 104]) and have done the reset. No change in the symptoms: power light comes one, fans come on, nothing else happens.

 

Hi,

Sounds like a power supply issue. Try taking out the power lead and if there is an off switch on the psu turn that off too. Press the button that powers up the pc and hold for 30sec. That should clear the remaining power from your motherboard. Plug the PSU power lead back in and turn the psu on. Power up and see what happens.

 

its nothing to do with your external speakers its a tiny speaker that plugs into your motherboard , if it doesnt have one you wopuld never hear it obviously *Wink Im trying to determine if your pc is posting past the bios if not you can reset the cmos eithewr by moving a jumper , pressing a button or removing your cmos battery (depending on what mobo you have)

 

ah well in that case you need to make a bootable usb or dvd , if that fails it could be psu , mobo , hard drive failiure , ram issues allsorts which we can troubleshoot , sounds though like its prolly just a windoiws issue. (wpul;dnt hurt to make sure everything is plugged into your mobo properly too especially the 24 pin plug on the left side *Smile

 

I can see that the NUM Lock and Caps Lock LEDs on the keyboard toggle on and off. I don't think it's a power button because the fans turn on when I power on. I've cleared the CMOS and there is no change in symptoms. I'm trying to work my way through DELL's No POST/No Power/No Video article, but I'm not clear what the diagnostic LEDs are that they mention...

 

If the PSU has failed you can still receive power - it's just not enough to boot up

Perhaps get on of these:-

Leegoal 20 / 24-pin Power Supply Tester for ATX / SATA / HDD, Black: Amazon.co.uk: Computers Accessories

It helped me determine the faulty PSU when exactly the same thing happened to me. I just bought a new PSU and I was back in action. The pic of your computer's PSU connections look standard but Dell can be a right git as they sometimes use propitiatory connections.
