Plug in and it should fire back up! Pull the power cable from the power supply, and keep the power supply switch in the “on” position for a minute or so. I would recommend you contact our … I guess I’ll have to remove them now, but my question is why are these things sold in the first place if they can cause problems? thanks dude it worked saved me la lot of panic. Unplug the computer then hold the power button down for 60 seconds then release and wait another 30 seconds then hold the power button again for 60 seconds.Now plug in the computer and try to start it. Instead of panicking right away, take a look at your PC and the connected components. It's a fine line and sometimes hard to tell. You can follow Martin on. If the power supply connections look ok, but the computer still doesn't turn on, the motherboard may be bad. PSU testers run about $10. Good catch… How that “U” got into OSHA, I haven’t a clue! Save my name, email, and website in this browser for the next time I comment. You want to discharge the capacitors. [Motherboard] Troubleshooting - No Power/No Boot/No Display. No Power, in this case, can be defined as either the system not receiving any power from the power source or the power not being distributed in the system correctly. Case power switch failures are the type of hardware that normally shows either DOA from day one, or intermittent after years of use. Not sure though. …computer not POSTing is pretty easy to diag: – Is the power led burning on the motherboard (Asus has always a green led on the motherboard that is on when there is power, even if the computer is off). Good thoughts, Mr. Joey. Just make sure you don't touch anything hardware related after you open the PC while it is turned on. I removed the battery using a flathead, checked the voltage and it seemed slightly down (2.5V instead of 3V). I think that my problem may be the motherboard or the PSU. There is a small button (usually yellow or red) on the motherboard, usually near the cmos battery. My PSU is working as well as my motherboard, and I know this from the LEDs on the mobo- the power one is always on, and toggling the TPU or EPU on/off also shows their LEDs to be on. Push the start button. If the problem persists, check the video or graphics card (if any). If you are reading ghacks.net GPU is almost idle and its power consumption is at very, very low level. 2. However, the fact that nothing happens is a clue in and of itself. Check to see if your motherboard has an onboard power button. Yes, there are a million stories in the city. I just installed new RAM and it wouldn’t start. PC’s are so power efficient that it doesn’t use that much extra power to keep it running. Open the left side of the PC panel. Or you had a electrical outage in your location that could’ve also triggered the switch and have seen this happen over the years with certain PSU but not all. Turn it on to see if the problem persists. Power efficient? (I got a total of 14 years of good use out of the Zenith; they don’t make ’em like they used to.). Don’t leave us hanging! There’s only one computing device that can be left on 365/24 with minimum power consumption, and that is a regular laptop that maxes 65W power consumption! Q: == Any way/app/utility in LINUX to measure the voltage of the MB CMOS battery, without opening the PC…?. All PC's, laptops, desktops, towers will always boot into the BIOS without a hard drive.A hard drive, working or otherwise, is not required to get to the BIOS settings screen.. If you suspect that the Power On Self Test is still going on and that Windows has not yet started to boot, a better troubleshooting guide for why your computer won't turn on might be the one from above called Computer Stops or Continuously Reboots During the POST. (Accidentally set it to 120V while connected to 240V power) No other known faults with the mobo-doner PC. It was the first time I’ve ever had a computer outlast the PSU. Then I tried to turn it on 1.5 weeks later and nothing at all. One of the first things I do each morning is to power on a PC. Check the power and reset buttons at the front. Thanks for the good advice, Martin and Mr.Joey! Check the memory. I thought sure I’d never encounter that again. Any of you guys familiar with a digital multi meter? I use the motherboard insulating washers to protect the motherboard from getting scratched by the screws. As far as components are concerned, the most important ones are the power supply unit at the back that supplies power to the system, the motherboard, the processor, the video card, and memory. Chrome is blocking downloads? As far as I know, I didn't bang it into anything and personally carried it. Use a power switch downstream (likely on the power supply) until a replacement is procured. While I'd suggest you turn off the power before you do so, you may get important clues why something is not working if you keep the power on for a moment longer. I have tried everything in HP online steps. I have a button on the backside witch sais CMOS, and it was pulsating with a blue light. If power is out completely, those won't work as well. PC wouldnt boot up before, so I switched out the CPU and motherboard from an older PC whose PSU was fried. If you work on these things long enough, you know to keep a CR-25 battery (new, in it’s sealed package) in your tool kit. Imagine my surprise when my PC would not boot at all. Is the power cable plugged into the wall and the ot… Then not at all. Also, check that memory and the video card are connected properly. I mean you’ll need min 100-110v~ or 200-220v~ to run your computer’s PSU. PCs have a power on/off switch on the back usually. Now I ALWAYS look at the motherboard screws! 3. Another funny thing i’ve seen a long time ago : There was blown up capacitors on the mb (on a old motherboard which had a Pentium 3 on it), and they were causing random reboots. Once you have done so, it is time to check the connecting cables. A slight variation on this solution is to remove your power cord (from the PC or laptop) and hold the Power On button for 30 seconds to 1 minute and then connect the power cord back again. I suppose I could pull the battery and test it or just replace it and hope for the best but the PC is inside my desk and its a pain to get at. However, after 30+ years in this, looking at the big picture, a computer that won’t power on, or one that spontaneously powers off, tends to be power supply related, probably half the time.

It runs 365 X 24. I’m referring to your question, trek100. Also, make sure the power connection is working by testing it with another electronic device. (CPU Temps etc are very stable BTW). As those pins are (almost) directly forwarded to the PSU, if it starts the fans, the PSU is outputting power, if it stops spinning soon after, it means the Motherboard is not picking up a “power good” signal from the PSU or there is a problem with the motherboard/videocard to get past the POST. We wondered about this back in 1981. Additional info: This is going to sound so OSHUA to y’all, but seriously, before touching MB components, like making sure RAM and PCI cards are “fitted” snugly, grab one of those static discharge wrist bands and fasten the wire (usually on an alligator clip) to a metal piece of the case. Check the CPU. I swapped out the PSU and the PC worked fine for a couple of weeks. I have no idea what OSHUA stands for (and neither, it seems, does the Internet). Many power supplies have an external switch located at the rear of the unit. I suppose you could engineer something at the hardware level whereby a running and powered system could somehow cut power to the CMOS, thus flipping it to battery back-up, and take a reading, report this to the user, and then set power back on to the CMOS. A 500 watt power supply doesn’t pull 500 watts just from being on. They are MEANT to get scratched by the head of the screw (makes for good contact). This guide provides you with tips that may help you fix the not turning on issue on your own. You can quick check this with the multi-meter without even opening up the power supply, just touch the two meter probes to any two metal prongs on the power supply where the cable was plugged in. Ever notice that different holes have a different number of little dots around them? One thing you can try is remove any component that is not required to run the PC. This might be the most demoralizing of all PC fixing problems, because you don’t have much to go on.
