Computer won't stay on for more than a few seconds

Hylian7 · 05-12-2009, 05:40 PM

I've had this computer built for a few weeks, and things have been running fine. Today, I opened it for something, and then when I put it back together, it wouldn't stay on. All I was doing was making sure the GPU was seated correctly and had all the correct power cables connected to it, so it was all that I touched. I tried a few things, such as unplugging everything and putting it all back together and it did nothing. I noticed one thing though, I unplugged my CPU and it stayed on (with the GPU still in). If I took out the GPU, and left the CPU plugged in, it stayed on. What am I doing wrong here?

Specs:
585W Power Supply
500GB SATA HDD
SATA CD/DVD Burner
XFX nVidia 9800 GT graphics card
Intel Core 2 Duo 2.8 GHz

I have some more information. I have confirmed that it will stay on if EITHER the CPU or GPU is plugged in, not when both are plugged in. This means that if I remove the GPU, it will stay on. Likewise, if I unplug the CPU's power, it stays on as well.

First make sure your CPU's heatsink is in full contact with the processor. I had this same problem.

It always has been in full contact. It ran fine before I opened the case today. It also stays on when the CPU is plugged in and the GPU is not plugged in.

Anyone else have ideas?

Hello Hylian,

Can you list the make/model of the MB?

Also list the PSU brand. You may have a failing power supply.

do you have another power supply you can test with? Since its only a few weeks old, you can still probably RMA it

Recheck the legs on the CPU Heat Sink you would not be the first person to nave one pop off by moving the PC.
