Computer Shuts Off After Starting Up.

Hey,
So I recently got out of College for Spring Break, I loaded my working computer into my trunk on it's side, if I remember correctly it should have been laying with the motherboard on the bottom faceing up. I drove to my mom's house(About an hour of driving), I then drove and picked up my younger brother from his rifle club meeting(about 30-40 minutes of driving) We put his rifle bag in the back with the computer which had slid a little. When we got home we were both tired and left his bag in the trunk with the computer for the night. The next day the computer sat in the trunk all day, Later that evening I took my brother out to McDonalds and we got shamrock shakes(For St. Patrick's Day) Which was about (30-40) Minutes of driving, when we got home we removed his rifle bag from the trunk and the computer spent another night in the trunk. This morning around noon I left for my dads house which is about (10-30) Minutes of driving depending on how fast I drive. Once I got here I unpacked my computer and set everything up(Yes I set it up right I do this quite often and I know how to plug things in). I went to turn it on, and it turned on and got to the point where I was suppose to log in, I entered my password and hit enter, a few seconds after that it died, the power just shut off, no warning or steps, just as if someone pulled the plug. I turned it on several more times, switched the plug from the power strip to the wall outlet, and I opened up the computer and watched it. The computer then offered me with the Option of Repairing the windows Files, I selected that rather then an ordinary start up, it died immediatly. I looked online and saw that someone was having issue with the Power button wire, so I pushed the Power button on my Motherboard and the same issue happened. I then unplugged the Power button wire from the motherboard and turned it on, it died at a rate that seem quicker, as in it didn't let me start up, I unplugged all the Front Pannel Plugs and got the same results. I called my brother who is better at me with computers, he suggested that I remove the RAM all except one to see if I had bad RAM, I did that to all 4 sticks I had, THe computer actually shuts off much sooner without the RAM, as in before I get to the login sceen or even chose to start windows normally. I've given it all the trys that I know how to.


Information:
OS: WIndows 7 64bit
CPU: Intel 2 Dual Core Duo
Motherboard: NVIDIA 680i SLI Motherboard
Graphics Card: NIVIDIA 9800 Geforce GT
RAM: 2 2GB Sticks and 2 512MB Sticks(My brother sent them free with the motherboard so why not use em?)
Power Supply Unit: Cooler Master 500

I've had issues with older PSU's where they would work, THis was about 2 weeks ago where I went 3 weeks without a computer so I'm rather tired of this computer not working.

 

Hi Extursion and welcome to Computer Help Forums

Unfortunately Computers don't like travelling something to do with vibration

first thing to do is take out all the cards, already done the RAM but their is still the GPU Card and make sure they are all seated properly (Pull Them out and Pust them back in)

Next thing is to check all the connectors are ok, give them all a firm push,

then see if you get anything happen when you try to start up.

if no joy report back and well start looking more in depth into the problem.

Just for reference, I keep the Original Case Box and Packaging for transporting.

 

Well, I did as you said, I removed and replaced the Grpahics Card, replaced all the RAM and Then firmly pushed on all the plug things I knew of, No Luck, It turned off about 5-10 Seconds after I entered my password, durring the Welcome Screen.

 

SUCCESS! My CPU Fan Was loose, And I remember my Uncle, Brother, and a friend I had work on my computer last time it was broken mention that without a CPU fan it wouldn't work. I noticed my was loose and tightened it.

 

Yep that would do it, Glad your up and running anyway
