So here is the case where an easy project has turned into a complete nightmare.

I wanted to upgrade to two video cards using SLI. so i went and purchased two new 9800GTX+ then alas they would not fit in my case so i bought a new case and my power supply need a little boost so i bought a new PS. well the PS i bought did not have enough connections and the computer wouldnt boot, i troubleshooted the best i could, got frustrated thinking it was the CPU so i went and bought a new CPU and MB, now im still experiencing a turn off during boot.

Here are my Specs of wat im working with
Cooler Master FullSize Case 4 Large Case Fans
Corsair 750watt Power Supply
Asus p5N-D Motherboard
4 1 gig corsair DDR2 PC 6400 ram sticks
Lite-On BluRay burner/player
tring to use TWO xfx 9800GTX+ cards (tried using only one pc still does not boot)


Here is what i have tried so far :
1- move/lessen the amount of RAM sticks
2- took out one graphics card
3- tried one graphics card and even a different Power Supply
4- thermal gel is just right
5- cpu heatsink seems to be on tight enough

I dont know what is wrong or what im forgetting. and i have a very hard time believing that two MB by different Manf. went bad so im thinking i have done something wrong?

the old MB worked lastnight with ONE of the new cards ALL of the memory and the HD and BD drive, and the first Powersupply that i bought incorrectly yesterday.

thanks for any help

ok here is a slight update and maybe an early end to this thread with no help needed .

So being hard headed like i am i re checked everything and it looks like the proccessor fan may have not been FULLLLLLLY seated..... go figure i have built 3 systems before and this is such a silly error on my part. maybe ill become a millionare if i can figure out a better way to seat these ******* proccessor fans because these clips are horrible. hopefully you all will see me around otherparts of the forum and not worring about this problem anymore

If you think you're the only one that has messed up a system -think again.
That's how we learn, don't be embarrassed, just DON'T DO THE SAME THING TWICE

Thats always a positive way to look at it .

Hello tmcglynn.

So is this issue resolved now that you found the heatsink askew?

Yes this specific problem is fixed, Im still having issues of random BSODs with vista that i'm still fighting through. but no more as i appairently called it before a comouter turning off during boot.

Right then, marked as resolved.
