My old PSU was on it's last limbs. I should have known sooner because the cpu fan would have to be flicked to start spinning. It failed on me while playing a game, my computer locked up and I got a distorted screen. After waiting a while I tried to reboot and got the same distortion at the winxp load screen.

So I got a new PSU. I installed it yesterday and my machine boots up smoothly, except the monitor isn't getting a signal. There are no beeps from the machine and no visible damage. I don't know what's up. Could my video card or monitor gotten damaged? They look okay. The fans spin up and nothing is visibly wrong.

I tried resetting the bios, using analog cables, and later today I will test the monitor on another computer, as well as try another monitor on mine. Googling got mixed results and nothing I found seemed to be similar to my problem. I'm hoping I can find some help here.

monitor is 226bw samsung 22" widescreen
video card is evga 8800gt 512mb
mb is ECS Geforce6100PM-M2 AM2+/AM2 NVIDIA GeForce 6100 Micro ATX AMD Motherboard
new psu is CORSAIR CMPSU-750TX 750W ATX12V

Sounds like the video card may have gone blooey on you. Try pulling it and seeing if the onboard works ok.

Ouch. I hope not. Will try this out later as I am unable to atm. Could a blown power supply do that to a video card?

My card has a lifetime warranty, although only if you register it within the first 30 days, which I didn't.

A blown PSU has the ability to damage any part of the system. But most good quality PSUs have safeguards in place to help prevent other components from failing. So its always important not to cheap out on the PSU. For those cheap PSUs that will damage a system its no uncommon for it to take out the CPU and RAM. Often a PSU failure causes a surge of power threw the system which is what destroys other components.

so I managed to get the video card into another machine to test since my mb doesn't have onboard video for me to test at home.

The video card gave fragmented screens in the second computer, but it did start to boot up. So this means that the video card and MB is damaged on my machine? That's like 500$ lost on top of the new PSU I bought. I am very angered and can't believe in this day of age something like this could happen.

I want to make a note now I am on a personal vendetta against anything OCZ. I will not ever buy anything related to them even if it was a cure for cancer. I am outraged that this company has fixed their warranty system to cover the exact amount of lifetime their products last. My PSU failed just weeks after the 3 year warranty expired. There is nothing they can do now, and I am out several key components in my machine due to their hillbilly manufacturing. Screw you OCZ, from a poor college student who is out of a computer and going to have to rely on unsanitary school computers surrounded my immature imbeciles in the campus library.

OCZ genreally has good PSUs and good built in protection. Something had to go seariously wrong for it to die as hard as it did. But i doubt the PSU is to blaim. The problem you encoutered with the artifacts points at a bad video card. If it was from a dead PSU the system would have shut off and thrown up smoke and/or sparks. An 8800GT is an older card and i have seen many poeple with dieing 8800GTs in the past year or 2. So before you go off half cocked, get a new video card and test it out. You may find that everything is fine.

No one said they where the greatest. But they are good enough to prevent damage to other components in the event that the PSU fails. But i agree OCZ isn't in my top 10 list of PSUs.

Not necessarily... my bro's PSU started going way out of spec and pumped his graphics card (9800 pro at the time) with nearly 16VDC :eek: no sparks, no smoke, just fried vid card. Thankfully nothing else got cooked.

It was a piece of crap rosewill PSU btw.

At the time I first wrote this I was taking into account the cost of replacing the mb, cpu, video, etc.

Also, it wasn't the psu that went bad after all, it was the video card. After receiving a very well written personal email reply from ocz my opinions of them changed of them back to positive.

my favorite part of the reply to read was:
"The first and last are the most common. Obviously, if the computer had been working for a while, you did not make any connection mistakes. However, in most cases where a claim is made, we find something inside of the power supply. We have found flies, giant dustballs, bits of metal shavings or dust, lizards, and most recently a nest of cockroaches."

I could copy / paste my invoice totals but argueing over how much parts cost now vs then isn't going to get my computer fixed.
