Must pull cmos battery for 7 64bit to start up but not XP
Have working XP on one hard drive. Wished to do a clean install on a 2nd hard drive. After 4 days of trying to install Windows 7 (both 64 and 32 bit upgrade versions)
Reduced the system down to:
Asus M2N-SLI Deluxe motherboard,
2G ram stick
DVD drive
500G HD
processor/fan
non USB keyboard/mouse
Flashed the bios, reinstalled chipboard drivers on the xp, 8 hours or testing the ram stick memory-no errors, and any other thing I could think of during all the attempts (there were too many.) Always the system would freeze and BSOD at Windows starting screen with the splash icon (Was trying to boot the install straight from store bought disks) with various bsods.
On a whim took out the cmos battery and moved the pin over and back. Install starts.. goes through to complete installation and does the normal reboot. BSoD again at windows starting. Do the cmos battery and restart the install from scratch but this time turn the computer off during any restarts and redo battery/pin. Windows 7 64 finally installs with no errors.
Now windows 7 is running beautifully with no problems except when the computer needs to be turned on. Unless the cmos battery is pulled for a few seconds (realised do not need to even move the pin) it will go into a reboot loop during the windows starting screen. I do not have this problem when I load up windows XP (each on it's own drive).
Suggestions?
P.S. Battery voltage checked. It's over 3.1
Edit note: Resetting the bios in the bios window to defaults by pushing F5 and then saving does not do the trick (I do not touch the bios between boots ups either). The battery must be pulled every time.
