Win 7 Install Registry-Write Crash

(moved by me from another post)
I have been trying to install Win 7 (32-bit) on a 1st-timer new build (post works fine) and keep getting crash right after "Setup is updating registry settings". Installation goes into repair/recovery/etc. Had installation completed several days ago (working at it part-time...), but repeated crashes resulted in trying to do clean re-install. Problems first time as well, seem to have been fixed by installing drivers in repair mode. Have tried same this time w/o success - may not have used same sequence. Would work from setupact.log log file, but don't know how to read and fix results (have looked).

System specs:
CPU Intel i7-920
Motherboard Gigabyte GA-X58A-UD3R bios.F5 (updated)
Memory 3x2GB GSkill F3-12800CL7T-6GBPI
Graphics Card Gigabyte Radeon HD4850 1GB
Sound Card use mobo for now
Monitor/Display PNP display (no name) max reso 1400x1050
Screen Resolution 1400x1050
Hard Drives 0) OCZ 30G SSD - model OCZSSD2-1VTX30G
1) Samsung Spinpoint 500GB #HD502HJ
PSU OCZ850GXSSLI
Case CM-RC690
Cooling Artic Freezer 7 Pro Rev.2

No joy, need some help. Anyone have some ideas?

I suspect the install DVD. Try installing from a thumb drive.

Have tried that a couple of differnet times as well as the DVD many times.

Setuperr.log might reveal is causing the prob - usually the last entry is useful..

Faulty memory can cause reading errors (Run memory diagnostics from 7 Install disk)

Hi, have you got the ram in the right slots.

To boot with 6gb of DDR3, you need to have the ram in the WHITE SLOTS, not the BLUE SLOTS. (Gigabyte's site)

Casca & Hubris: Checked Ram, ok and in correct slots.

Re-installed again from USB, no joy.

SIW2: thanks - will try setuperr.log and setupact.log to see if I can pull anything from there.

Just a thought. Pull the SSD and attempt install to HDD only. Adjust BIOS accordingly.

Casca: If I pull the SSD and install to new partition on HDD, that wipes whatever is on the HDD, correct? Don't have much there and not sure if I can get it off, but want to know first. Thanks.

Yes and no. First, do not delete any partitions or format the target. If you have a Windows directory, it will get saved if you DO NOT choose Upgrade.

You will have an opportunity to do a Folder level review of the drive contents at the "F6" screen where you are asked if you need RAID drivers. I am not sure what will happen if a Users folder exists.
