Self Restart When Installing Windows Right On Uncompressing Files 0%

[code] everything is detected with in the bios but the boot device LED stays solid on, I've booted it from a Windows 7 DVD then THE COMPUTER RESTARTS?!? It's only restarted after I've booted from the DVD, sometimes when it's at the language part but always does it when its at the install part right at uncompressing files at 0%.Now I've but about 6 rigs over the years without a problem and it's really getting to me. I've tried most sata settings (IDE & AHCI), different hdds, different sata cables & ports, cleared the CMOS(removed mains power, removed the CMOS battery, moved jumper waited 5min, held down power button, waited 5min, replaced battery, moved jumper back, replace mains power) the mb memOK function gives the RAM the all clear as well as the windows memcheck after 5 passes, everything was seated with a wrist strap, I've checked the ssd with sata to USB interface and my laptop gives it the all clear (oh yeh I chech with a diff HDD) and the mb has the latest firmware, USB flashed.
