Backup Rig won't turn on! HELP!

post #1 of 8
Thread Starter 
Ok, so my backup computer has had these issues before. I unplug everything and let it sit for about 10 minutes then I remove the graphics card to do my work and then replace the graphics card (making sure to check all the connections throughout the computer). Then I plug everything back into my setup and I get nothing, my computer does not turn on. The CPU fan twitches just a small bit when I push the power button but nothing past that.

It has done this before, I let it sit for about a week and it just randomly started working again. Suggestions? Thanks!

Try going through and checking all the power connections and ensuring they're snug. Modular PSU? Check both ends in that case. I've also had a modular cable be bad out of the box (for SATA).

If those are good, check how the video card and RAM are seated.

After that, try using a different power switch, as they can cause a twitch problem, too.

If the problem still persists, then I would start scrutinizing the power supply more closely.

Go ahead and reseat everything in your case. My first instinct is the power supply, either inside or on of the cables came loose.

Sounds like a PSU issue. If the rig isn't too powerful just buy a good cheap PSU for it. Antec Earthwatts comes in both 380 and 430 PSU and is bronze certified.

Loose cables and/or a bad soldering job somewhere. If it's just barely making content it may only work under the right temps/humidity. If that's not the case first thing i'd try is replacing the PSU.

Also just because a cable is all the way in, does not mean its getting a good connection. Unplug every cable and replug it back in. Make sure your Power On/Reset/etc cables for the case are not touching and are correctly installed. Also make sure your computer is plugged all the way into the wall, and that the cable is snug in the back of the PSU.

Test your psu using the 'paper clip' method.

1. disconnect your psu from your pc.
2. on the 20/24 pin cable take a paperclip and jump the green wire to any of the black wires.
3. plug in your psu to a wall outlet and turn it on. The psu fan should spin up. You can also connect a fan to the psu and see if it spins up.

If it doesn't, your psu is fried.

Well I personally feel like I shouldn't own a computer. It was my power switch! Since the OEM dell power switch only worked on the OEM Dell board I had to use a small square momentary switch out of an older 98' computer. Took the old switch out, replaced the switch as well as hotwiring the PSU and it works great. Thanks guys +Rep

Glad it worked out. Step 2 from my post worked. Yay! I've run into this a bunch in the past. Sometimes the switches just wear out. Hopefully this is one of those moments you'll remember for a while, to help someone who doesn't yet know.
