BSOD NIGHTMARE

I keep getting bsod's.
It all started when I first put the computer to gether i didn't realize that the PSU was too small and blew resulting in a power surge that fried the HDD 1TB and the motherboard but luckily the graphics card got out ok but at the time we didn't realize that themobo was fried and only reaplaced the HDD with a 500GB one because eclipse computers kept sending faulty ones back.
so my local computer shop put it together and it worked...... for a while then BSOD started to appear at random intervals sometimes after a couple of hours other times after a few minutes they got more frequent and started happening on safe mode as well!
It got to a point where BSOD where happening on the LOGON SCREEN!
So the pc shop found out that the mobo was fried and we sent it back.
It took 3 MONTHES for a new one to arrive so we formatted the HDD and did a clean install of windows the shop installed all of the core drivers and AVG and Far Cry 1. They said that they played on Far Cry for 2 hours straight and the PC ran for the entire day without any sign of BSOD.

BUT when i got it home i installed Norton 360 (newest one) and then i tried to install Microsoft Flight simulator X Deluxe edition and WHAM BSOD!!!
and nowi can't log on because it restarts or BSOD or freezes after i log in.
Safe Mode just don't work sais loading files then odd colours at top of screen then restarts, i've tried taking graphics card out no difference.
but startup recovery works fine some times.
AND and this is a big and I CAN'T REINSTALL WINDOWS!! When i put the disk in it boots from disk and starts windows install then BSOD HOW CAN I GET THIS OFF THE INSTALLER DISK.

But i also have splash top on my pc it works fine never crashes.
Please help I've been working on this since October 2010
and have spent over £700 on this thing HELP!!!1

My AMD Phenom black edition has 6 cores but on startup it sais only 5 cores are active when before it said 6 where active.
plus atomatic over clocking is on.

i can't access windows!

most of the time

Run Safe Mode with Networking and then create a BSOD Report: https://www.sevenforums.com/crashes-d...tructions.html
If can't, then run Startup Repair: Startup Repair

I've tried what you said to do but windows just won't work I've attatched a photo of the BSOD that appears.

Here's the minidump.
I can only access my computer if i go on Safe Mode with command promt/
And when i start my computer up it says only 5 cores are activated but i have a 6 core cpu whats up with that.
