I recently started another thread here for help on getting a new motherboard. Well I got all the things I ordered yesterday, I took all my old stuff out, plugged all my new stuff in, put it all together. I double checked everything and it looks all right, so I hook it up to my monitor and keyboard, plug it into the wall, flip the power switch, and turn it on. IT STARTS! Yea, I was happy, but it boots to the screen I was getting before my computer died last time.
"Window was turned off unexpectedly blah blah blah... Would you like to open windows in safe mode? Safe mode with networking? Safe mode with command prompt? Open window in last know working mode? Open windows normally?"
SO I figure this was cool, so I opened it in the last time it was working, but instead of opening windows, my computer just turns off. So I turn it back on and try to open normally. Same thing happens. I turned it back on and tried Safe mode. Same thing happens. So I figured that I'd go into setup. So I turn on the computer and hold F2 going into setup. I look around there for a bit and was almost about to exit when my computer just turns off. The same thing that started happening before my old motherboard fried!

But last time it did that we blamed it on the PSU. I have a brand new 500W PSU, so what's wrong?! I started up my computer
again and this time I tried to start normally, and it started to show the windows loading screen but then suddenly it rebooted. So I tried again when it came up, and it did the same thing! So now it's not turning off when I try to start it up, it just starts over. ***?!
Does anyone know what could be wrong and how to fix it? I just spent $230 on a motherboard and parts and I would like to have it fixed befor I leave for vacation on the 5th. Any and all help will be greatly apreciated. Thanks.
