Re: Sudden computer freeze...and barely reboots!
Opps almost forgot there is a power rail dedicated for the vid card...386 i have ummm misplaced the memeory..

do you know which one....it is important if you have a high end gaming card and most psu's will state how much power they deliver to each rail...
Well, I believe the video card uses the 5V rail. In your example, that power supply has one 5V rail. There's not one dedicated for the video card. So all your 5V devices have to share that rail. You may have a lot of cable strands and plugs, but they're all soldered to the same place. Other things that also use that rail are hard drives, cdrom drives, pci cards, agp cards, USB devices, etc... Yes, most of your goodies are going to be on the 5V rail. Most of the wattage of your whopper power supply is on the 12V rail. While that's good for braggin rights it not sufficient enough info to decide if you have what you need to run all your stuff.
On my Enermax 460W PSU I have 5Vx35A. So even though the total wattage is less than yours, mine has more power where it counts (on my system). Not knocking your power supplly btw.
I don't know the model of waterinthefuel's video card or power supply. But he could easily get an idea if it's sufficient for his system if he's willing to look a little deeper than the overall wattage.
WTF needs:
a good working video card
sufficient power to every component of his system
clean power that doesn't fluctuate
If any one of those 3 things are not in order the symptoms WTF described could occur.
I am inclined to think his video card or power supply is bad because it hangs during POST. Even a crappy power supply will usually let you boot. It's not until the power supply can't keep up with the demands that you normally see problems. Running a game for example, will require more power to the video card than just surfing the internet.
Now here's the part that really sucks. It's rare but it happens. His power supply could be bad. It could wreck every brand new known good video card he plugs it into. Just like a bad motherboard can fry every brand new processor you put in it (and vice-versa). It doesn't happen that often but it has happend to me before. With the power supply, I avoid getting into that situation by using my tester. With CPU's I guess I'm just screwed.
Some other stuff to play around with. Unplug stuff... hard drives, cdroms. Take out cards like network and sound. That'll give you more power on your 5V. Troubleshoot. Make the system consist of very few parts. If it doesn't fail, add parts back piece by piece.
If he's got an extra power supply laying around, he could give that a try and see if that changes the symptom. It should at least boot.
