My girlfriends Win 7 Pro x64 computer.
Today 10/27/2014, The video on the monitor started extreme jittering and I tried everything to just shut down the computer ( the curser was frozen ). I tried ctrl-alt-del etc. and nothing worked.
I finally hit the reset button and then the computer went into a continuous loop of trying to boot ( nothing showed on the monitor, no UEFI, nothing but black ).
All of the lights and fans would run but it kept trying to reboot over and over.
I had made an external backup HDD for her computer so I tried that and the same sequence of events happened.
I noticed that when I pressed the power button the HDD activity light comes on once and then doesn’t come on any more during the reboot loop.
Now the HDD activity light doesn’t come on at all when you press the power button but all the rest of the lights and fans come on
and nothing comes up on the monitor. The computer just runs and doesn’t even go into the reboot loop.
I’m wondering if the MotherBoard or CPU has a problem?
Don't take yourself so seriously, no one else does
