I am having serious issues with my windows 7 64 bit pc.
I believe the issue is hardware related but unable to determine cause or solution.
About 3 days ago computer froze and crashed. Restarted the computer and crashes occurred within 30 or so minutes. Eventually the pc failed to boot and windows startup repair found error but reported unable to repair.
However I could boot with safe mode. Transferred files in case of drive failure and reboot was working for a while. Crashes continued until boot failure once again but safe mode worked. Safe mode and then restart allows me to boot normally for unknown reasons for a while.
Crashes were giving a consistent error in a ".sys" file with error code 1060 in windows event viewer. So I decided to reinstall win7 OS. I attempted upgrade install. Installation failed.
So I tried clean install on unused hard drive. Removed all other drives before starting. 5 attempts all failed usually at the "completing installation" phase. Error message only said "unexpected" restart which caused OS install failure.
I have no idea which component is causing the situation.
Any ideas for troubleshooting or solving this situation is appreciated.
