I was wrong......
The CHKDSK C: /F /R command did not fixed the problem in my cause although the computer desktop was up and running for a while without any STOP error.
But at last it happened. I put the computer in the hibernate state overnight. In the morning the computer was dead and the screen was turned off, I could not see any message on the screen and could not wake up the screen to display its content.
I may assume that the KERNEL_DATA_INPAGE_ERROR with STOP code 0x0000007A has occured again, but the computer behavior is now different. Before the repair action with CHKDSK /F /R I could make a cold restart by turning power off and on again - now even the cold
restart fails and there is no HDD present anymore, the BIOS setup shows that no HDD is present. The lack should indicate a cable problem, but I do not think it is the cause here, however, further analysis will be performed. The HDD should be intact - I haven't
seen any indications concerning defectives on the HDD.
However, the try to repair using the CHKDSK made things worser and the defectives indicate that a serious BIOS problem has occured, maybe caused by a virus infection?
So let's see how the story will continue ....

Hi,
The story is continuing......
Since my previous message I have been talking with both the Microsoft support and the hardware vendor.
The Microsoft support has been paused for a while, the hardware vendor accepted this problem as being related to hardware and has replaced motherboard as well as HDD and carefully checked all cable connections.
Warranty conditions applies in my case - the computer was bought a number of months ago as well as upgrading from delivery status, Microsoft Windows 7 Home to Ultimate.
I got the computer back two days ago (Monday afternoon) and until now I am going to check it carefully, system has been restored from backup and a number of software updates have been (operating system as well as other softwares so the computer is not crying
for updates and restarts all the time anymore.
Now I am going to check whether the STOP 0x7A problem still persists. Let's see, indeed the actions performed are close to replace the whole computer (new motherboard) and the HDD was replaced, too, as being the critical thing pointed out although I don't suspect
the failure to be caused by the HDD or related directly to it.
But to be honest, I have to say that there were more problems than the 0x7A STOP condition related to the HDD.
Another issue is that I have an USB attached printer device and after having the computer restored from the hibernate state the USB attached printer has failed to reconnect more than 20 times since being installed in late June this year. It is a relatively
seldom appearing state, causing printer driver to fail with a general system error 5 code (from system log, no dump is taken).
But the fail is similar, external device connection fails in conjunction with computer being restored from the hibernate state. If HDD fails, then STOP 0x7A is issued, if USB attached printer device fails then printer driver fails with a system error 5 issued.
None of these conditions are normal, they are hard to reproduce and the cause is still unknown.
Let's see if these actions regarding replacing motherboard and HDD were effective with the desired result. Until now nothing has happened, but the computer was fixed and returned only a very few days ago.
