I just put together a new computer and I am trying to install windows xp home(It was free through school). After about 15 minutes into the setup the computer just shuts down, right in the middle of the setup. no error message no warning at all. I don't know what is HAPPENING and I know that Raidmax isn't the best PS but I need help I am at a loss. Thanks!

intel core 2 duo E6700
asus p5w dh deluxe
sapphire x1950pro 512MB ddr3
2 GB g.skill ddr2-800
Seagate 320 GB SATA HD
Raidmax 500W PS with Raidmax case
I noticed you have som mismatched RAM...try PULLING the 512 stick out and see if it installs...
Also check the CD for smudges/scratches...clean it with a lint free cloth.
If neither of these work i would SWAP out the PSU and try that.that's the memory on my video card.
the 2 GB g.skill is my RAMGotcha...sorry my bad.
Reading too fast again.
Try the other suggestions and let us know.You might try removing any unnecessary devices as well. Many setup issues are due to incompatible hardware. Sometimes you can install the hardware after the installation with better luck. You might have a modem or sound card that is preventing windows setup from completing. Try removing them until after windows gets installed. Check that your graphics card has a power connector if required. Check that all your fans are functional as well, the system may be overheating. all my fans are going. all my peripherals are on my mobo (i.e. soundcard, modems, wireless.)
I checked after it turned off and it was barely hot.
I checked to see if my CPU heatsink was seated properly on the chip.
I just ordered a seagate 580W PSU and we'll see how that goes. if it doesn't fix the problem then I'll be back.

I suspect it is a PSU problem. after it shuts down I can't immediately reboot the system, even if I manually shut it down. Then I flip the power switch off then on and I can reboot.

I let it sit idle in the setup menu and it still shut off. that's why i don't think it's a heat issue.
