Hello,
just built an entirely new system using an MSI A75MA-G55, AMD A8-3850, 16 GB (4x4GB) Kingston HyperX DDR3 1600 and a pair of Seagate 1TB drives (hoping for RAID 0)... locking up randomly during first-start... typically locks before I can get to startup, sometimes as late as starting Win7 setup (from new Win7 DVD). Any ideas?
 
Pat, thx for the idea...

turns out a beefier power supply did it... ran to Best Buy an hour ago and grabbed a 600w Corsair GS600... and a case to fit it. Re-started the fresh installation and all went smooth.
 
Your config can't be pulling 200 watts and the Diablotek PSDA450A 450 watt psu can't handle it. maybe send the Diablotek PSDA450A back to whoever you bought it from and have them send you another to put in your spare parts bin. It can't be working. (or is it that bad a psu... ?)
 
I would also consider the possibility of heat... the CPU heatsink (AMD OEM) was too hot to touch in the old case, the new case (Antec) has a couple of 120 mm fans near the CPU... the heatsink is warm but not near as hot as it was before.
 
in the setup, I did notice the temp running around 65 to 67 C, now it is showing around 60 C.

Perhaps a $5.00 fan would have been smarter troubleshooting, but I do like the roomier case and beefier power supply.
 


Sometime it is not the quantity but the quality of power dispatched to component. With lower quality PSU, or aging PSU, it is sometime advisable to bump voltage in BIOS for RAM or even CPU.
 


Bad power supply put more stress to voltage regulator and may have them working harder and creating more heat. Even if your old PSU would have done the job with some BIOS help, you are still better with your new PSU
