We had a power event at our house the other day. I received a robo call from the local power company at 08:37 AM that beginning at 08:30 AM the power would be out of service at our house for 3 hours while a transformer was being replaced with a new one. I have 7 uninterruptable power supplies (UPS) consumer grade. I knew they wouldn't be able to sustain power for 3 hours, but I just left every thing set like it was with 3 computers running. The power came back on after only 2 hours of being off. When it came back on the power surge took out my 8 port KVM switch. I had it plugged into a power strip instead of one of my UPSs. A dumb mistake I made maybe 4 years ago and didn't realize I had till the KVM switch quit working.
While waiting for my replacement KVM switch to arrive, I Wanted to be able to continue to use the 2 PCs I use most. So I moved my Windows 7 64-bit Pro PC to a secondary monitor that sits a little farther away from me then does my primary monitor. After the move this PC booted up and everything was working fine. Because the monitor was a little farther away from me I wanted to change the screen resolution on the secondary monitor so that the characters wouldn't be so difficult to read. I am used to setting monitor screen resolution on PCs by the numbers like 800x600, 1024x768, or 1900x1600 etc. The screen for making this change required a little exploring on Control Panel to locate. One of the options presented to me was 125%. A 25% increase looked just about right to me. So I clicked the radio button to select that. I don't remember the exact sequence of events that took place after that, but I did want to make the change in screen resolution without interruption. I didn't have any other programs running on my task bar.
I was presented with a sub-window that said reboot was required to make the screen resolution change I requested. So I clicked OK. That was the last time I saw my Windows GUI on that PC in a normal mode. I must have botched the restore process to a restore-point using Control Panel. Now every time that PC boots up in normal mode the screen goes completely dark after what appears to be a normal Windows 7 Pro start sequence. If I just let the computer run, it eventually goes into hibernate mode. But I know that the OS is running OK because I have Windows Media Center (WMC) on that PC. At times that I know that I have TV shows scheduled to be recorded, this PC will come out of hibernate mode, record the TV program, and go back into hibernate mode. I can also reboot in SAFE mode and go to the USB hard disk directory that my TV programs are recorded to and see the WTV files with the date stamps that tell me that those shows were just recorded that day. So I know that Windows 7 Pro is running OK, but I just can't see anything.
More than once in this saga, Windows would give me an error message that says "Windows didn't start . . . ." It would then give me an option to allow Windows to do an automatic restore to the last known good restore-point. The outcome of that process was never what I wanted. I also failed to burn a "Restore Disk". Another mistake that I'll not make again given my current experience. I am not sure that I will be able to replace all the software I have installed on this PC should I decide to reinstall Windows 7 Pro on it. It came with WMC already installed on it and no disk should I need to do a reinstall. It was supposed to be a multimedia PC at the time I bought it. Microsoft has basically abandoned WMC and wants everybody to convert to Windows-10. That is two other stories I don't want to write about. I have already written too much here.
Does anybody have a fix for this problem that has a chance of success?
