The power supply LED is lit and not flashing, and the fan in the power supply runs.

Other than thatI get no signal to the monitor and it goes directly to sleep. The machine does not even beep at all. I have tried to remove the battery, removed the memory cards, unplugged and re-plugged all connections, tried starting up with hard drive, CD Rom, fans unplugged did not unplug the USB's however.

The only things plugged into the MB are the two fans, four pin plug from PSU, the large 24 pin plug, and the plug for the power switch. I also removed all memory cards. Plugged in monitor and power cord and turned on. Fans start for one second and you can immediately hear them slowing down to a stop. Power LED is on constant, power supply fan spinning.

Also disconnect any internal USB fly leads from the motherboard. Locate the round silver battery in the bottom right corner of the board.So I have a TI in my computer and when I boot it, it spins first then stops. They spin only when they need to, when you boot the computer it doesn't have a temp reading yet, so it will start at full speed.

Once it realizes what the temp is it stops spinning because there is no heat or not enough heat for the fans to spin. This is just to save power and prevent unnecessary wear and tear on the fan bearings, increasing its lifespan. Let's get something straight, the pc does not start turning off parts of itself when it has insufficient power, it's not a human body trying to keep its core warm.

If the PC had insufficient power, it would just shut off without warning. The card will never use watts. Unless this guy has a ton of devices sucking power from the PSU, watts is sufficient. The modern cards are made that way. On the older cards the fan was on all the time.

On the modern cards, the fan stops and stays off until the card needs it. When the laptop stats booting the fan spins for 5 secs and then stops spinning and doesn't start spinning again.

But after restart it again spins for 5 secs and stops again. We decided to send both of them back in exchange for a the same but different serial CPU and a newer motherboard. Finally it worked. You just have to diagnose which PC part it is.

You are not getting to the the POST routine, so, the gpu is not a factor as the processor is not running or looking for components To be thorough, unplug the A.

Now press the power on button. If it works, the supply lost power unexpectedly and it is a feature of the newer supplies to have to be reset as above, If you. Its because of this ridiculous demand the public has for "A Quiet Computer". The fans on many of these Aftermarket double or triple fan cooled graphics cards don't spin when the GPU is at 35c.

Wow, that's quiet, uh huh. Quiet with lots of RGB lights. So much for the old days of loud Delta and Scythe fans, cases with closed of side panels and a mm fan of the side door.Menu Menu.

I pushed the start button and the case fan would spin a little and stop repeatedly, the graphics card light would flash, the mother board has an ezdebug feature and the light next to the cpu option was blinking.

Frustrated- PC wont start (Fans spin a Second and go off)

The fan will even spin for a bit after I flip the power switch off, but eventually stops. I have looked online for fixes, I cleaned out the dust with compressed air, I have tried plugging the power cord into a different outlet, removed and reinstalled the MOBO battery, held the start button after turning off the power, reinstalled the graphics card which I had to take out to get to the battery.

So far no changes. I built the computer over a year ago and until now it worked fine. If anyone has a fix for this please help me. Can you tell me what happen prior to this problem. Did this hardware ever work? If it did what happen? Did you have Brown-out that's when the power goes off and quickly goes back on.

Would you have to unplug the entire power supply unit to test it? The computer worked fine for a year. In the last few months it would sometimes not start unless I turned off the power strip connected to the wall outlet and then turned it back on.

Sounds more like a PSU problem than anything else, but other candidates can include voltage regulation on motherboard and a bad fuse on your power strip.

CPUs and motherboards can be checked at local repair shop but try to prove their reputation before going in for help. If anyone knows a way to check CPU or motherboard individually, I would love to hear it. None of my multiple systems or those of my 'best' friends are compatible Cycloid Torus said:. Primativ said:. Ok thanks for the replies. I think I fixed my issue. While I was looking at my motherboard I noticed that the cpu fan was connected to the sys fan outlet, and that one of the case fans was connected to the motherboard cpu fan outlet.

I swapped the position of these cables and tried to start the computer.Forum World Records. Sign In Sign Up.

So now only the processor iKcpu 8 and 4 pins plugged in, and the ATX power is connected to the board.

Still does the same thing. The last numbers on the serial sticker are I have also tried the new bios which seemed to successfully install Any suggestions? One update.

PC fans spin for half a second only, replaced motherboard and psu also..

Could you tell me what board it is? To help us help you - please provide as much information about your system and the problem as possible. It is indeed a Rampage IV Extreme. I have tried to boot using both of the BIOS. Neither will post.

RMA the board I am sad to say. Will this have to be done though ASUS? Or should I contact the seller newegg? Just curious if you have any experience with it? I think newegg is 30 days Typically with an RMA you'll be waiting a bit longer than going to the point of purchase and resolving it that way. Thank you very much. Submitted the RMA to Newegg, and they accepted. Thank you for all of your help, both of you! Just to add, your next board may do the same thing if it needs a Bios update for your CPU.

Just FYI. EDIT: I just noticed you just posted this, check the long thin sticker for the last 4 numbers on the end. It will be the Bios version your board came with. Last edited by MrPeter; at PM.

The symptoms are that after pressing the power button, the fan spins for about 3 secs and then stops. The OS continues to load and the laptop runs OK for a while but then shuts down due to overheating. Thinking it was the fan itself, I got a replacement fan and swapped it out. No change. The laptop otherwise runs fine but shuts down when it overheats. I don't see anything to force the fan to run continuously or adjust it in any way.

One thing I did notice when disassembling it was that 2 of the screws between the hinges had damaged sockets indicating that it had some impact on its edge in the past.

Maybe this damaged the motherboard?

PC starts for a second then stops, then repeats

Any other suggestions? Hi, have you blown through the laptop to make sure vents are clear? You may have to renew the Thermal compound between the CPU and the heat sink.

Log in or Sign up to hide this advert. Hi Neil. Yes I had the laptop fully stripped down to the last screw. All the vents are spotless. Why would replacing the thermal compound make this sort of difference?

Is there a sensor that would be affected by that? As you, I would suspect physical damage. Not much you can do about that, besides replacing the system board. Arie .Forums New posts Search forums.

System boots for 1 second, cpu fan spins, system shuts off, repeat. Thread starter White Falcon Start date Apr 23, White Falcon. Joined Apr 15, Messages 36 0. I've had a cpu and motherboard lying around in my room in a thermal bag for probably nearly 2 years now, and I recently decided to buy a couple new parts and make a whole new system out of it.

After trying it without the hard drive, the disk drive, the video card, switching around the ram, I decided it was probably an issue with the psu I had lying around, and as such I went to buy a new one. After setting it up with that, the same problem is still occurring. Joined Jan 18, Messages 0. Do you have the button behind the mobo to CMOS clear? I don't have the button for it, But I have two pins on the board for cmos clear It specifies: "Short - clear cmos Open - Normal" I've also got the ram kit I used to use on this motherboard currently plugged into my current system Maybe that's the easiest test.

Kaynar: Attempted my old ram sticks, didn't work. I'm unsure how I'm supposed to 'short' those two pins to clear the cmos, but I've tried numerous times to remove the battery to achieve that, as well as buying a brand new one and using that, still no dice. Maybe there is a short? If it's in a case can you build it outside of the case just for testing? There is sometimes a 3-pin connector with a jumper on two of the three pins.

Switch it over should clear the BIOS unless you have a button for it instead. If you give me a minute, I probably could find it in your manual for your board. Joined Apr 19, Messages 12, 4. White Falcon said:.
