New computer shuts down after 30 seconds Tags: Homebuilt Systems Last response: January 7, 2007 12:52 PM in Systems Share JPF January 6, 2007 4:29:42 PM I just put together my first system. Case: ANTEC TX640B MB ASUS P5N-E SLI NF650I MEM 1Gx2|COR TWIN2X2048-5400C4PT CPU INTEL|C2D E6400 VGA Gigabyte GeForce 7900 GS (GV-NX79G256DP-RH) DVD_BURN PHILIPS|SPD2410BD HD: WD 250 SATA2 After I turn it on it will run for about 30 seconds before powering off. When it starts my CPU fan, 2 case fans, and VGA fan all run. My HD and CD/DVD drive whirl. A few times I have been able to get into setup where it shows my HD, CD/DVD, memory, CPU First i get the ASUS screen, if i hit DEL to enter the BIOS I have about 10 seconds before it shuts down, if I dont hit DEL it says: "setup is detecting your hardware config" then, "windows setup" then press F6 to run RAID something press f2 to run something else ... thats as far as it ever gets. Any help would be greatly appreciated. Thanks. More about : computer shuts seconds JPF January 6, 2007 5:02:14 PM Thanks mplichfamily, Looking at my system are there any PSUs that you recommend?

For a thermal shutdown, after 30secs, then he doesnt have a heatsink or used 2 tubes of thermal paste I also go with the psu.
