Computer Booting Problem

Posted Today, 01:45 AM

Hello,

I built my custom computer about 4 months ago, and it's been smooth sailing ever since now. I turned on my computer and the monitor displayed the message "no input" so I fiddled with the DVI input on the monitor itself, unplugged the HDMI from the back of the computer, then did a hard power reset to restart the computer. Upon pressing the power button to boot it up, the fan LED lights turned on for a brief split second, the disk drive made a short whirring noise, then everything turned off. It would do this every 3 seconds until power was directly cut off. I tried to troubleshoot the problem and could only think it would be either the motherboard or the power supply. The CPU fan would also turn on briefly too, suggesting the motherboard has power. I also tried other power cords and the same issue happens. I'm at the loss right now, any help would be greatly appreciated! Here is a video demonstrating the issuse:

 

Is there a reason why you have no RAM in the system?
Also do you have the 8 pin power port for the CPU plugged in? It is in the upper left hand corner near those gold heat sinks.

 

GimboV made a good point regarding the ram, but I'm assuming that the Youtube vid is not your machine but just an example of what's happening to you.

You've told us that you suspected a bad power supply. Have you tried a known to be good/working PSU?

 

I think the video is his machine, the video was posted to YouTube by the same user name on May 8th.

 

This seems strange.Why would one post a Video with obvious no Ram?
I don't see the point, unless as Frank says it may be an example.
I have struck four common things that cause this non Boot, and Gimbo has named two.
The other I struck was a stray riser was left in when changing to different brand motherboards.
Also a duff PSU will give the same symptoms, from my experience.

 

There's no post beep....no error beep for no RAM...there's no GPU installed.....what is the monitor using.....the onboard video? What is that TS box that's connected to your PC? Can you list your PC specifications please?

I'm with DSTM on this as well; in all my experience these symptoms are directly related to a faulty or bad PSU.

 

Asus boards do not have a speaker by default so unless he hooked one up there will be no beep codes. The TS box is the power supply. If the 8 pin power is not connected for the CPU the board may exhibit this type of behavior. This is due to the CPU not receiving enough power.

 

The computer in the video is the one with the problem. Even without the RAM installed is still has the same problem. The computer does not even attempt to boot up, the fans run for a brief second then turn off, along with the LED case lights. Everything is properly plugged in that needs to be plugged in. The computer specifications are as follows:

ASUS Z97‑E/USB3.1 ATX Motherboard
Intel Core i5‑4590 3.3 GHz Quad‑Core
2x Corsair DDR3 8GB RAM
EVGA GeForce GTX 960
XFX TS650 PSU
Corsair Carbide 500r Case

 

Have you swapped out the Power supply, as Frank suggested?
Have you pulled off the back side cover and looked at the back of the riser/standoff threads in case there is an orphan riser shorting out the Motherboard?
I had this happen a long time ago and it only booted up for a fraction of a second.
You need to heed the advice given or we are no further ahead.

 

Would you be able to post a new video showing everything plugged in and the computer trying to power up like the last video?

 

I tried a different PSU - a 430W stock PSU that came with my first computer. I have taken a new video showing everything plugged in (sorry for the atrocious cable management):

 

Thanks for that.
Is the 24pin connector pressed firmly home? Sometimes hard to seat right home.
The next thing I would check is to make sure the Motherboard is not shorting out.
Even if it means R/R the motherboard.

 

I would also ask if this was a new case?

 

Another couple of things you could double check. Remove the cpu, check pins and reseat.
Make sure heatsink fan connector is on the correct connector marked "cpu"on motherboard.
If it senses no fan connected it can switch off.

 

To add to Dougie information you may also want to clean the thermal compound off and reapply fresh.

Did you use the risers? Are they tall enough?

 

Everything is firmly connected. I'm now thinking it's definitely a faulty motherboard or CPU. It's weird because it was all working flawlessly for about 4 months until all of the sudden this started happening. I'm going to contact the hardware manufacturers.

 

This was the case I originally built into, it was all working fine until suddenly out of nowhere it all stopped working. Hopefully the manufacturers will work with me and send me new hardware.

 

Risers are definitely tall enough, I triple checked this before I started the build. The thermal compound is fresh and should not be the problem, I am going to contact the hardware manufacturers and see if I can work with them to be supplied new parts.

 

That sound just before it powers off sounds to me like a faulty power supply. Even with too much thermal compound it would boot into BIOS before overheating.

 

try removing the cmos battery and then put it back after 5 minutes
