I have upgraded cpu and motherboard and ram, everything else stays the same.
I was hoping that i dont need to reinstall windows.
Now every time i boot into windows, the computer can run up to the starting windows screen then it will automatically restart just before login screen appearing.
Is this a hardware problem or software?
I tried windows startup repair tool. It does not help.
I really dont want to reinstall if theres another way.
I also tried load optimized defaults in bios and i ran windows memory dianostics, no problem found.
I suspect its software problem.
Update,now i know why my computer restarts automatically, i disabled automatic restart on nsystem failure, then i get a blue screen.
I tried booting into safe mode, that doesnt work either.

This almost sounds like you added an SSD to the system as well, but you didn't mention that.

Is AHCI enabled in the BIOS? If so, try switching it over to IDE instead and see if that cures the problem. Normally defaults will run IDE instead of AHCI, so I doubt this is it, but it's a shot in the dark.

What exactly happens to Windows when loading in safe mode? Same blue screen? Any note on which file or fault? It may be a corrupted Windows .dll or the like.
 
The only components are these,
Cpu, went from core 2 duo e8600 to amd fx 8350
Mb went from gigabyte ga-ep45t-ud3lr to gigabyte ga-990fxa-ud3
Ram went from corsair cmd4gx3m2a1600c8 to amd memory rg2133 2x8gb
Bluescreen code stop:0x0000007B(0xFFFFF880009A97E8,0xFFFFFFFFC0000034,0x0000000000000000,0x0000000000000000)
Thats all i changed in my system.

That's "all you changed"? New CPU, motherboard, and ram is practically a whole new system. You also went from Intel to AMD.

I'd have absolutely no expectation of being able to just plug in your old HD and go after those changes. Sorry, but if you genuinely want that system to be anywhere close to stable you need to reinstall windows.
 
Mushkins got it. Unless you removed all the Intel drivers from device manager before the change, you will need to reinstall Windows.
 
You need to have the generic Windows drivers installed and not hardware-specific drivers to "transfer" Windows 7 to a mobo with a different hardware configuration. Otherwise, it will not boot.
 
Motherboard for sure. Changing mobo's changes WAY to much stuff. Heck just changing the a chipset is usually too much.

you may be able to get by with a repair, but I'd recommend a re-install.
 
Mushkin is exactly right. Stop 7B means that Windows couldn't find the driver for your primary disk controller. You might try changing the SATA controller setting in BIOS to legacy IDE mode. If that doesn't work, it's time for a repair install.
