Help computer wont go through post

elektrichead22 · Sep 11, 2014

I lost my gaming pc for the first time and I am very perplexed.. after running well for ten months it wouldn't go through post. all fans are running case fans, cpu fan, gpu fan, psu fan... but I get no beeps or video output. I tried unplugging all extrnals as well. I tried swapping out five year old 750w psu to see if that helped same issue... I then assumed it was a dead mobo so I bought a new one same issue so then I assumed it was a bad cpu or that the old mobo fried the cpu so I bought a new cpu still same problem... so here I am with a gaming pc with the cpu led lit up and staying on and no clue what to do....

have you tried to post, with just a single ram and nothing else (other than mobo and CPU of course)

xreap · Sep 11, 2014

also this might help, http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems

Then again let us know if your ok with booting with a single stick of ram and just the cpu on the motherboard so we can find whats the problem by the process of elimination

elektrichead22 · Sep 11, 2014

I have tried swapping the ram too... I am afraid it is the psu because that would be the next logical step but there is the fact all the fans are spinning.... not sure if that means anything though

xreap · Sep 12, 2014

Are those fan connected to the mobo fan headers, or the psu? By the way is the fan on the cpu heatsink running?

JimF_35 · Sep 12, 2014

Do you have a debug display on your motherboard. If so what is the code?

elektrichead22 · Sep 12, 2014

all fans are running the ones connected directly to the psu and the one connect via motherboard and th psu fan itself and I just double checked that check list

elektrichead22 · Sep 12, 2014

oly ouptput I am getting from the mother board is a red led light on the cpu led that is staying on red... the manual says this means there is problem with the cpu.. I had this on both my old cpu and the new one I installed an hour ago.

xreap · Sep 12, 2014

this is a new MOBO and CPU correct?

elektrichead22 · Sep 12, 2014

correct. Not sure if it matters but I tried booting up with the old cpu first.

JimF_35 · Sep 12, 2014

This sounds like you need to do a firm ware update. Were you able to boot with the old CPU?

elektrichead22 · Sep 12, 2014

no I was not able to boot with the old cpu

JimF_35 · Sep 12, 2014

I hate to say this but have you checked for bent pins?

elektrichead22 · Sep 12, 2014

both cpu's the old and new one are straight as arrows.

JimF_35 · Sep 12, 2014

If it is not the CPU and its not the RAM then its the motherboard. I would see if you can get it RMAed from the original seller.

elektrichead22 :

did you check if the other 4pin in the atx powersupply is properly seated?

Guest · Apr 29, 2016

Is the PWR_BTN cable connected?
Also, Check all the cables properly.
