Sometimes simple problems are hard to find! Especially when someone else has been in there before you. I never have liked Dell computers, they have a long history of doing weird and/or flaky things like that power connector on the motherboard.

H man im straggling with my computer. It was working fine suddenly after power failure. Doesn't want to go on but the boad is light. No fan spinning. On pc board and power supply. But if I press small button behind the Power supply fans will spin and DVD Rom will light up and hard drive will run. Soon I release it everything went off again. Is dell optiplex 980
That usually means there is a short somewhere. Disconnect all drives, cd/DVD, floppy if you have one and take all the extra boards out. Then try to start it. If it starts you have a bad component if not the motherboard might be bad or it has bad caps. You can try removing memory too and see if it will at least beep or flash the led.
I have an Optiplex 7020that keeps blinking and will not do a post. I left the power on for a long time and now this is the result. I took the memory out and inserted it back but it has not changed.
@@AERVBlog I did the power supply test. pulled both cables from the MB and pressed the test button and it did not light up. I may be the pwr sply is bad.
Help! I have a dell gx230...won't turn on...on switch is flashing...yellow light inside the computer (auxiliary power?) is on...I changed out the small battery inside the computer...nothing...what next? Thanks.
Hello I need some help my dell optiplex 7010. When I turn on my pc it doesn't show any beeb or light led but fan is still working. And when I touch button to power supply sometime it's working and dead again.. And what happened to my pc was not showing up any beeb and light. How to fix that?
If it is blinking yellow it is probably a bad motherboard. If it is solid it is probably the power supply. Listen to the power supply closely when you turn it on and see if you can hear it squeal a little and then go silent. If so pull all the cards out and disconnect all drives. Try to turn it on again. If it works reinstall each thing one at a time till it won't start. The last piece is shorted. If the computer does not start barebones then the power supply or motherboard is bad.
Sir my cpu is 7010 dell optiplex . i5 3 rd generation processor included in it. One month ago my cpu went to dead,one guy who work in a computer service center asked my cpu motherboard dead. Sir you please suggest an another any mother board any brand to suitable for my cpu.
Hi Man, I hope you’re still here being tech support. I have a 7020 which I took apart to do some case migrating on but later decided against it. Put everything back did that by accident the system tries to boot but says errors like CPU FAN 0 FAILURE and then if I bypass that and choose Setup it doesn’t detect my SSD, please help me fix this :))
Hello, do you know what to do if a Dell Optiplex 755 desktop computer turns on but then on the screen it says “Your PC has ran into an problem...” and it resets by itself and then goes to automatic repair but your mouse and keyboard won’t type? I called Dell technical assistance but they don’t want to help me because I don’t have the newer models of their computers
What kind of mouse and keyboard do you have? Is it wireless? Those might not work before it boots up. They should but I have seen them fail on pre windows screen. Your error usually means that some DLL or system file did not load right. Sometimes you can just reboot and it will fix itself. If you have a wired keyboard, either USB or old fashioned plug try using that.
AERVBlog the keyboard and mouse are wire and they would when the computer turns on but all of a sudden, when the computer says “Automatic repair” it gives you an option of “Restart” or “Advanced Options” But I’m not sure why the computer shuts off power to the USB ports and it’s not letting me log in
@@keving.6163 Can you get to the advanced options menu? If so you could try to do a system restore just in case the latest update failed or somehow messed up your computer. Failing that you could do a complete reinstall but that would lose all your data and programs. I don't think you need to log in on that screen.
AERVBlog Well it’s okay if I lose all my computer data and everything but I just want to try to get my computer back to working position and when it does the automatic repair, it gives me options after that but for some reason, it disables my keyboard and mouse when it does that but when I turn it on, I could only use my keyboard for F2 and F1 and then it sends me to a set up, but it’s okay if my only option is to reset the whole computer, I just need to know how to do that
Basically I put in extra ram into mine and it started orange flashing on the power button so I took them out and it turned on for a second then went completely dead, no power what do ever, not even on the mother board or anything, and it isn’t the cable
At this point you are going to have to have a meter to check voltages. See if there is anything at all on that plug. With the unit just plugged in there should be a 5V standby somewhere. It is used to turn the computer on when you press the soft on/ Offswitch.. If you can't find that then you have a short somewhere or a dead power supply. Good luck. Thanks for watching.
Thanks for this video, sr i have the same computer, but it doesn't turn on, i tried to press the power button, and nothing happens, but the PSU is fine, could you please give me a solution?
@@Octavio_Jorge If the fans start to spin but then stop it usually means that the power supply is crow-barring meaning it is seeing a large current draw, like a short, and shutting down. Start by disconnecting everything from the power supply except the motherboard and turn it on. If it does start then hook the peripherals up one at a time till it will no longer start. The last thing you plugged in is the culprit. If it won't start with just the motherboard hooked up then it is most likely a bad motherboard. Good luck.
@@jj-fx1dl have you reseated the memory. That is what the flashing orange light usually means. If that does not work take all the memory out and just put one at a time back in into slot one till you find the bad stick. Don't forget to turn the computer off before you pull out the memory and between each stick. If you only have 2 sticks be sure they are in slots 1 and 2. They are usually blue but not always. They should be marked on the motherboard.
@Digital World start by taking all extra cards out of the machine and all but one of the ram. Disconnect the HD and CD power then try to turn it on. The idea is to find out what device is shorting out the power supply. Hopefully it is not the motherboard itself. And carefully inspect all the capacitors, they look like little cans on the motherboard, for leakage or bulging at the top where the little crump marks are. If you have any bulging capacitors you will probably need a new motherboard.
@Digital World No. Do not wash your motherboard. Did you try disconnecting all the drives and CD as well as take out the extra boards? It is beginning to sound like a bad motherboard and there isn't much you can do about that. Sorry I can't be of more help.
If there are no lights or beeps or anything I would check the power supply first. It sounds like your 5V is missing. Of course it could be shorted somewhere. Take all extra cards out, disconnect hard drive and DVD and see it boots to bios. If it does connect one thing at a time until it quits booting.
saved me hours on trying to find the problem. Thanks :)
Your welcome. Glad I could help. Thanks for watching.

Yeah but.... gotta fix what I am given.
Thank you so much, i was about to do get new ram and powersupply. Taking out my hair, I put that little cable backwards. Thank you thank you.
Your welcome.
Sir my pc would even start if i hit power button it shows 1 and 2 blink orange

Try taking just one memory stick out at a time and then turn it on. You might have just one bad stick.
@@AERVBlog I did the power supply test. pulled both cables from the MB and pressed the test button and it did not light up. I may be the pwr sply is bad.
@@murahomesa that is a good bet. If you have a meter you can check voltages.
@@AERVBlog I do have a meter. I am in the process of ordering another pwr sply. Thanks for the video. Blessings!
Did you replace your power supply? or you just put it the cable on the right direction?
I got lucky and was able to just put the cable on right.
Help! I have a dell gx230...won't turn on...on switch is flashing...yellow light inside the computer (auxiliary power?) is on...I changed out the small battery inside the computer...nothing...what next? Thanks.
What is the flash pattern on the power light?
Hello I need some help my dell optiplex 7010. When I turn on my pc it doesn't show any beeb or light led but fan is still working. And when I touch button to power supply sometime it's working and dead again.. And what happened to my pc was not showing up any beeb and light. How to fix that?
If there are no lights at all then I would suspect that one of the voltages from the power supply is gone or the motherboard is truly shot.
My optiplex 390 is show a Orange light go no but no Screen and no deep help me please

Hey my optiplex turns on but won’t boot it’s the same w/out ram installed and with one only installed , any help ?
Do you hear any beeps?
Sir my cpu is 7010 dell optiplex . i5 3 rd generation processor included in it.
One month ago my cpu went to dead,one guy who work in a computer service center asked my cpu motherboard dead.
Sir you please suggest an another any mother board any brand to suitable for my cpu.
You can pick up the motherboard on Ebay for about $25. That would my suggestion.

The fans go full power and make a shit ton of noise in this process
The system says SETUP FAILED SYSTEM HALTED after the setup button is pressed
The only thing that does work is on board diagnostics
