Pretty sure my PSU is failing on me

post #1 of 10
Thread Starter 
I have an OCZ ModXStream Pro 600w PSU. Whenever I turn on my computer it boots, and at a random point, everything just shuts off, no HDD LED on my case, the fans are all lit up and running, the PSU fan is running, video card is running but with no display picture.

I plug in my bluetooth USB adapter, and it doesn't light up when I plug it into the front or back USB ports.

I recently switched to an 8800 GTS 320mb video card, since then it's been giving me issues. It runs 50C idle, around 70C-80C load.

I had this HIS 4850, and no issues. It ran nice and cool, 60C max.

It might be the video card, but since my whole motherboard is unresponsive, im thinking it's the PSU. Any suggestions?

My brother recently built a rig, he has a Corsair 650w, should I try that and see if it gives me any issues? Thanks!

To determine if it's the GPU or not, just take it out and then boot and see if it still does it. If it does, then there's your answer.

And yes, definitely swap PSUs after and see what happens. I think you're the first person I've seen with an extra PSU to test when something goes wrong like this

I was in Safe Mode and it still happened, so would I still have to take out the GPU to see if that's the cause?

I also tried a PSU Calculator, I should be getting ~400w with my rig.

I'd still remove it, you never know. If it's still happening give that PSU swap a go!

The essence of computer component troubleshooting is always part swapping. It's primitive, but there you have it.

Swap the easiest parts first, and move on to the harder stuff. If you can put the 8800 into your brothers rig and see if it murders it while simultaneously dropping the 4850 back in your own rig and seeing if it will run that'd be ideal (or if your brother has a stronger GPU, trying his in your machine would yield even better data).

That's exactly what i'm doing. He has a 4870x2. Unfortunately, I no longer have the 4850 with me.

I'll try putting the 8800GTS in his rig too, that's a good idea!

He doesn't want to let me touch his rig, even when I built it for him and I know more than he does about it

Okay so I've tried 3 different scenarios:

1. Plug in my brother's 4870x2 into my computer. Worked perfectly.

2. Plugged in my 8800 GTS into my brother's computer. Worked perfectly.

3. Plugged in my 8800 GTS into my dad's computer. Worked perfectly. He's still playing Portal on it...

I'm at a complete loss

Maybe my computer just doesn't like the 8800GTS

You may be right. I have read some complaints like yours regarding problems with your motherboard and the 8800 series. Check with ASRoc and see if there is a BIOS upgrade fix.

I was using a PCI-e 6pin to a molex converter that came with my 4850. I realized I had a direct PCI-e 6pin connector from my PSU, so I tried that after swapping out my brother's 4870x2, and everything is working awesome so far

Thanks! Rep'd all around
