Problem when powering up pc

[Larsie115]

Hi guys.

 

I tried to improve the airflow in my case by redoing the cable management (it was bad) but now when I power on my pc, the fans spin for half a second, turn off for half a second and turn back on and the pc continues to boot fine.

I didn't have this before and the pc works fine.

 

What I did:

I turned the PSU upside down (fan was pointing up) because my case supports a bottom PSU fan.

Moved the SSD to the SSD mount on the other side of the motherboard, I don't know why it wasn't there in the first place.

Reseated the GPU.

Reseated the CPU cooler which came loose for some reason while I was busy. (stock intel cooler)

I replugged all the cables into the motherboard.

When I powered on the pc it didn't boot because I forgot the CPU power cable (very stupid) but after I plugged it in it worked fine, except for the problem stated above.

 

I have also noticed some random stuttering while watching videos on youtube. (not noticed while gaming)

 

The temperatures are the same as before.

Memtest86: No errors. (4 hours)

Intel Processor Diagnostic Tool: Pass

 

I don't know if this is a big problem and I don't know what to do about it.

Any help will be appreciated.

CPU: i7 4770K 3.5ghz (no oc)

Sounds silly but have you triple checked that every cable is securely connected?

I wouldn't say for definite but it sounds like (from the fans and the stuttering) that a contact on a power cable might have been slightly damaged.

You are ABSOLUTELY sure that you plugged every single cable back in correctly?

Yes, also, I used an extension cord for the 8 pin cpu connector but now it's directly attached to the psu. Nothing changed.
