The computer I'm talking about runs Win7 x64 Home Premium. About 2 months ago both Mobo and HDD were replaced in 2 different occasions. At first it seemed the Mobo had gone so I replaced it and re installed Win 7 on it. After few weeks it was still playing up so I replaced HDD as well. Now just before Christmas my client rang me again saying that it has been behaving very strangely. Sometimes comes up with "Please select proper boot device", sometimes crashing while in Windows.
Last night while I was troubleshooting it I found that it has loads of SideBySide errors listed. The Error code is 33 and message is:
Activation context generation failed for "C:\Program Files (x86)\IncrediMail\Bin\MFC80U.DLL". Dependent Assembly Microsoft.VC80.MFCLOC,processorArchitecture="x86",publicKeyToken="1fc8b3b9a1e18e3b",type="win32",version="8.0.50608.0" could not be found. Please use sxstrace.exe for detailed diagnosis.
It mentions IncrediMail but it cannot be the reason why it also acts like this:
Last night I left it scanning for any errors on files through "sfc /scannow" It came up clean. I left the PC running and after some time it crashed. The computer restarted on its own and got stuck on the black screen saying "Insert Boot media" - just like there is no hard drive in it.
I pressed the reset button and it started up nicely.
Couple of other errors what keep reappearing in the Event Log:
Event ID 7026: The following boot-start or system-start driver(s) failed to load: cdrom
Event ID 11: The Driver detected a controller error on \Device\IDE\IDEPort1 - Source "atapi". This error message only happens maybe once a day.
I have disconnected the DVD-ROM it had attached (an IDE device) but Event 7026 still happens.
About 30 minutes ago I changed the SATA HDD to another slot on the motherboard - no Event 11 yet but as I said it only happens once a day or so.
Any help would be very welcome as I'm really struggling with it.
