Computer Problem
<div class="IPBDescription">and once again it's stupid D:</div> Last time it was my new gf 6800gt that was wierd and every1 said it was the psu, so I bought a new chassi with a 400w psu included. But now when I start my computer all the lights etc just flash in 0.5 sec, is it the enw psu?

What other alternitive components are you running? (How many HDD's, how much ram, how many fans, what PCI devices what CPU?). It's still possible that you are under the ammount you need in terms of wattage. Although it sounds like you just didn't plug something in properly...
Unless your secretly using a friggin lot of USB and PCI devices you should be decent on a 400W PSU. Although what you are getting definatly sounds like some sort of power issue. I'm somewhat stumped being unable to acctually look at the setup, when nothing whatsoever works there is a few thing that could possibly be wrong.
Assuming that when you say that all that happens is the lights start flashing you mean that none of the fans or HDD's come on (you should be able to hear them if thier active) I can tell you it isn't a direct fault of the video card, the HDD's, or any PCI devices. One thing to try, change the setup of the power lines so that you have each power plug powering as few devices as possible. In the past I have had problems when I have tryed to line power several fans while I still had empty 4 pin connectors that I was able to fix simply by hooking all the connectors to a device before I started roughting power through devices to other devices.
What ur interested in is the Output range..
Look at your PSU label (might have to take it out of the case)
And read off the Amperage ratings for each voltage rail (e.g 12V 30A 3.3V 10A ect..)
Post them here along with ur total system specs....and itll go a long way towards ruling yes/no on the PSU...

Then try removing motherboard components one by one. One memory slot, then the other... the modem, the graphics card (at least temporarily to see if it will stay on for more than .5 seconds), etc. Each time aftery, try restarting your computer to see if it actually boots up. Then reinsert the component and try with another component.
Try taking out the bios battery, then unplug your computer. Turn on your computer (yes, this is to drain any additional power left). Then reinsert the bios battery, and turn on your computer. Sometimes the bios is stubborn to recognize hardware changes, and if it expects something that isn't there, instead of going around it like most BIOS, it will crash and burn and not start your computer.
Try all of these things, and if it still isn't fixed, just have it repaired by professionals. Though, don't complain to us until you've tried these things and it still is not fixed.
