OK.
We are at the stage where you either
1. Proceed again with the fresh install.
THIS TIME HOWEVER - take the hard drive out of the computer and format it, on a FULL format, using the Western Digital utility.
The reason for that is that certain types of Malware can remain on the drive when it is formatted in the computer involved.
Then install as before but this time using the motherboard CD .
You can then LATER update from Gigabyte.
IF YOU TAKE this option I would NOT install anything other than Windows and drivers, until you have tested the system.
I would MOST CERTAINLY not reinstall any of your SAVED data. Even the Excel files.The other option
2. Is to go to our Malware forum, following the advice in the link
http://www.geekstogo...cleaning-guide/If you do that please provide on your Malware thread a link to the thread, so that Malware expert can see what has occurred here.
This would in the circumstances be of benefit ONLY to avoid the reinstall,
AT THIS STAGE.
The third option is to
3. Refer to Gigabyte via a Technical Support ticket (in the first instance) on this link
http://uk.gigabyte.c...al-support.aspxpossibly with a view to them suggesting a return of the board, if they opine that the error lies there.
If you take the third option, even if AFTER the first or second you can most properly inform them of what has been done here and if necessary they can of course view the thread as soon as you provide a link to it.
We could run another program to confirm the voltages on the PSU, as Speedfan did not register them, but the BIOS confirms they are OK, you could try another PSU. The memory checks out on both Memtest and WMD. The only aspect we have not tried is running it with just ONE memory stick, but I seem to think you tried all four in different combinations on both cores. HOWEVER I tend to think that, we have reached the stage where it is best to proceed with one of the suggestions on this thread.
The only issue remaining is that the BIOS on that board is a dual chip BIOS. There is a facility in addition to the normal SAVE and exit, to Save your settings to the backup BIOS chip. Originally that second BIOS chip, had known safe settings on it. If the system detected a BIOS corruption or UNSAFE setting, it would automatically run on the second chip. HOWEVER if you had at anytime SAVED settings to the other chip, rather than just SAVE and exit, then that failsafe on the second chip no longer exists.
Finally, please do of course keep us informed and I regret that my efforts have not been successful and I wish you the very best.
