New build boots OK but freezes during install

I am putting together a new system and it is driving me batty, the system just freezes up, no particular time or reason. It does POST ok, and memtest86 seems to run just fine. But as I am putting in the OS, it will lock up somewhere during the process. I have installed the OS about 15 times, I did get it all on one time but the system would intermittently freeze. It seems to be a timing or interrrupt issue, but I just may be jumping to conclusions.

Details on the parts:

CPU = Intel E8500
MOTHERBOARD = Gigabyte GA-EP45T-UD3LR
RAM = Mushkin DDR3 1333 2x2Gb
HEATSINK = Intel, 49degrees
OS = XP, Vista or Win7, all display problem
POWER SUPPLY = Antec 500W
VIDEO CARD = Sapphire 4830
SOUND CARD = Onboard - Realtek
CASE = LianLi
HDD = Seagate Barracuda 7200rpm 250Gb & Maxtor 80Gb Both are SATA

I have tried the minimal boot process and the freezing still occurs under that condition.

There is really no time or reason why or when the freeze will occur. Sometimes, I get all the way thru the install, the system restarts and then it freezes during the reboot. Sometimes the logo will display and freeze, other times, the system freezes during the painting of the image so I get a scrambled image

The Memory calls for 1.7 - 1.8 volts. The board comes configured for 1.5 I've tried 1.5, 1.7, 1.76 and 1.8 All display the same problem.

I've tried optimum settings, Minimum settings and custom settings, all show the same problem

I've tried upping the Northbridge voltage a couple points but no change

If I run an app to takes over the system, like Partition Commander or MemTest, the system seems to run OK - but I may have just been lucky or didn't use it long enough

Any ideas? If it wouldn't post, I'd blame the Mobo, but in this case, it tries to start and then it can't.

Suggestions or ideas

Thanks,

Paul

Is that one of the seagate hardrives with the firmware freezing issues?

You can do a model check and contact Seagate here:

I happened to have it handy as, I too, have a bad one... Takes a few days, though, to have them verify the problem and get you the firmware - I guess they're being picky because there are also some drives out there that can be bricked by inappropriate updating of the firmware...

what os do you have? once i was unable to boot into windows once because a bios setting was changed that was for 64bit OSes ( mine was 32). it was called memory hole or something. it happened after installing ubuntu.

I'll get you a 'workable' batch of BIOS settings - I've got to do a little looking first, as you've got a 't', and I don't see a lot of DDR3 - I wasn't willing to pay for it; in the meantime, what do you have plugged into USB? And, what BIOS settings are you using for it? USB problems are pretty common on the 'd' family of MOBOs...
