my computer turns off almost instantly after turning it on and then turns back on.

slan44 · Jan 20, 2015

so as the title says i try and turn my computer on and almost instantly it turns off and then 3 seconds later it turns back on but same thing almost instantly back off. this all started when i was cleaning my computer of dust yesterday and i decided to re-wire some of the cables from the psu around the back of the motherboard too make it look more tidy. i did this for main motherboard power supply the the secondary motherboard power supply (i think thats what it is called) and the GPU power. it was a tight fit on the other side of the case when i put the sides of the case back on but it fit pretty easily. i am thinking that i may have damaged the motherboard as i did touch it on a few occasions although i did try to touch the case occasionally to relieve static electricity. any help would be really appreciated.

My specs
PSU: Seasonic G-650
GPU: xfx Radeon R9 280X
CPU: i5 4670k
Motherboard: MSI Z87-G45 Gaming
Case: NZXT Source 530

Check if your CPU cooler fan is working.

Disconnect the OS drive. Connect an internal speaker. See what post/beep error code you get per http://www.computerhope.com/beep.htm

Internal speaker eg http://www.amazon.com/gp/product/B00BBJDNCG/ref=pd_lpo_sbs_dp_ss_1?pf_rd_p=1944687622&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B002W4M0DW&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=0YKQSV91YR8QBWVBNPS5

See your mobo manual for where to attach it.

was that meant to come with the motherboard because i am almost certain i dont have one of those, is there anything else i can use instead?

No. You'll have to buy one of them.

Or just take your PC to a PC repair shop.

i am thinking of testing the parts in another computer, so the problem would either have to be with the motherboard or PSU but the motherboard and the graphics card and everything do get power because all the fans start spinning and the LEDs on the motherboard work. so do i definitely have a faulty motherboard? i also dont think it could be the PSU because before yesterday when i tampered with the wiring there was no problems and i checked all the cords i took out were plugged in properly. so does that mean i have damaged the motherboard or could the problem still be elsewhere?

You need someone to help you. I can't tell you what you should do because you can't understand.

See your mobo manual for where to attach it."
