post #1 of 9
Thread Starter 
I installed my new, Coolmax CUG-950B PSU and now when I turn my PC on. My monitor say's "No DVI Signal" and Monitor shuts down. I've checked everything over and over again. When I uninstalled my old PSU. Every connection I unhooked. I Immediately hooked back up with the new PSU. I'm stumped. Any and all Ideas would be greatly appreciated.

OK

I'd reseat your GPU's to start with, that could be an issue, check all your PCI-E power cables and make sure they are tight in there. If that's all fine then take out your old PSU again, put that back in and see if you get the same issue.

It could be that there is an issue with the new PSU giving power to your PCI-E cards.

If the GPU didn't have PCI-E power wouldn't the alarm be going off? I would still pull the graphics card out and put it in again. You may have just bumped it a little or something.

What was the reason for the PSU change? Did the last one die? It is possible it took your GPU with it.

I have taking my GPU's out and put them back in I don't know how many times to make sure they were seated. I've swaped them around. I've tryed one, and then the other one. Last night I reinstalled my old PSU and everytime I get the samething. No DVI Signal. I had this problem when I first bought my Asus 24" LCD, HD Monitor. I can't remember how I solved it. I'm about ready to dig out my very old monitor and try hooking that up and see what happens. I know the GPU's are running and everything else seams to be running. Just NO dam DVI signal to my monitor.
I installed the new PSU because I was told my old 600 Watt. PSU wasn't enough for the upgrades I'm going to be doing. So I used Asus PSU Calculator and it said to use a minimum 800 Watt PSU. So I bought the Coolmax CUG-950B. I am Upgrading my CPU to a AMD Phenom IIx4 955. I'm just waiting on a PS/2 keyboard. Installing a SSD hard drive that I'm suppose to have today and soon. Windows 7 Pro 64bit. someday.

I just made sure my GPU's were seated, and they were. I hooked up my old monitor and got the same results. No DVI Signal. I then took out the two GPU's and installed one of my older 9800 GT's and got the same results. No DVI Signal. I then uninstalled the coolmax 950 and replaced the old 600Watt. PSU, again and got the same results with the 9800GT GPU. So I took the 9800 GT out and put one 550Ti GPU back in and nothing changed. I then uninstalled the old parts and reinstalled all the new parts. Coolmax CUG-950B PSU. and both Geforce GTX 550Ti 's. Still no DVI signal. So now I'm wondering if I burnt something out on my motherboard or maybe a hard drive. Any and all Ideas would be greatly appreciated.

My PC is up and running. A friend told me to remove my ram and reinstall it and to remove my CPU and reinstall it. So I did and my PC booted up. smile.gif

Removing the CPU isn't needed, This used to happen to our HP all the time, just reseat the RAM. It's usually because of dust.
