Hi,before doing this I would like to update , I have already done a fresh install of Win7, and it goes well, EXCEPT when I install the graphics drivers. After installing the graphics drivers (R9 270) (amd crimson 16.3.2) it goes into the same boot loop. Are the steps the same?
The idea is to do a BIOS update BEFORE you install windows and your MoBo manufacturers latest drivers.
1. Never let Windows Update install hardware drivers
2. Be aware that you will not get TS from MoBo vendors (i.e. Asus) if you do not have latest BIOS installed
3. Be aware that the latest hardware drivers, may depend upon having the latest BIOS installed.
Undoubtedly, as we have already seen, graphics drivers was not your original issues. Using F8, would have stopped any drivers from loading.
Clearing CMOS did solve your initial problem. The reason I recommended updating the BIOS at that point as you had nothing to worry about. Doing it after installing the OS could wipe out several hours of effort if the update goes awry
So with the BIOS issue out of the way, you indicate that your system install went south when loading the GFX drivers. Obviously, as you had no GFX drivers installed right after installing OS, booting into safe mode prior to installing would accomplish nothing as prior to that there was nothing to remove.
At this point I would.
1. If you want to get BIOS update out of the way, it's best to do it now whether or not it is related to your problem.
2. Boot into BIOS and use the "restore default Settings" option.
3. Reboot and check BIOS settings to make sure everything is correct
4. Format disk and install windows
5. Install original hardware drivers that came with your equipment of DVDs
6. Stop Windows from ever down;loading / installing HW drivers

7. Run windows update the 16 times or whatever it needs till it says "no updates found".
8. Create system restore point

9. Reboot
10. Install latest drivers from manufacturer's web sites for all hardware except GFX card
11. Reboot and create a restore point.
12. Install latest WHQL approved GFX driver
If you crash again, boot and press F7 to load w/o drivers. Restore to the latest restore point. (step 11).
At this point I'd contact tech support from your card vendor.
