BSOD after a new motherboard and processor was installed.

Hi all,
I have the blue screen that tells me there is an error and then the system crashes.

I have recently bought and had a shop install a brand new Gigabyte GA-B85M-D3H mother board and Intel i5 processor. It did have a AMD graphic card but the man at the shop took it out? I am not entirely clear why, he just said the onboard graphic was ok so it wasn’t needed? It also has a brand new 750W power supply. The machine has 8G memory, (2 x 4G) which indecently is the only thing I have not replaced, as the RAM is two years old

Window Home 7 is installed on a Seagate 2TB hard drive. (which is about a year old)

The machine boots up and I managed to set my WiFi router up and then it crashes with the blue screen. I reboot again and get the windows pop-up box saying it has recovered. Occationally when I restart after a crash it takes me to the instal windows set up screen.

I looked in the bios and it looks fine to and untrained eye like mine. For example the processor was running cool at 36 degrees. I compared the bios setting to the bios manual and its seems to be set to the manufactures default settings. I dont really know about conflicts and hardware. But when I bought the motherboard and processor I did check Gigabytes web-site to make sure they were compatible.

I am a bit confused as to why after the crash and I reboot Windows is asking to install. if I try to install on Disk 0 Partition3 it tells me I cant ? Probably because Disk 0 Partition 1 has the system already on it?

I also occasionally get a video display that look crazy before the crash, does this indicate something wrong with the graphics? I notices the Intel has an option to set the graphics but again it crashed before I could do anything?
I did try to download and install the SF Diagnostic tool but I got the blue screen of death again before i could run it I am sorry I dont think I can post an error report for you to help me

Thank you in advance

Um I will try that and get back to you Thank you :) Of course it driving me nuts cos I just paid a small fortune for the MB and Intel

I will try to post some pictures so you can see what im seeing

Hi Again,

I think I managed to run the SF Diagnostic tool...compressed it and saved to my USB key to tranferto my laptop . I hope I uploaded this correctly.

Still getting blue screen after the video screens throws a wobbly .... changed monior ..checked and updated drivers, within Windows 7 as cant check the internet for drivers as BSOD comes even when I boot in safe mode with networking. Tested the memory all is good. searched the net for a solution and I hit a blank wall and I have no idea how to proceed apart from formatting the drive and starting again. however doubt that formatting will help much as Im almost sure its something to do with the onboard graphics.

Here is the lastest update bit the problem still persists.
I deleted the partions and re-installed windows followed by the gigabyte drivers.
When completing the Windows intallation I noticed the VGA screen crashed while I was trying to enter the WEP key to my router. Upon reboot I skipped this step and windows installed successfully.

However, I can load windows fine but as soon as I try to connect to a Network (my internet router) I get the same flickering screen and the blue screen of death.

I have checked all the drivers and Ive rechecked the bios. Nothing seems to be amiss.

Any other ideas please ....

Well, after three days of searching the net and posting in sevral forums this issue is still not solved ....

I put back in the Radeon card and tried to connect to the internet ....as soon as I put in my network router key it crashed again ....

All things being equal I am about to chuck the damn thing out of the window !!
