|Obtained Acer M3640 with q6600 CPU, Bios version R01-A3.|
Former owner stated that original disk has been disposed due to a crash.
First hardware check shows blowed-up AGP card, I removed it.
No further visible damaged parts on the MoBo found.
Then cleaning up the dust from the MoBo like CPU/heatsink area, memory and other hardware.
Then first installation Vista Home Premium SP2, at the time I had no x64 Vista Home Premium version.
That x86 version installation went well, no problems encountered.
Next, I then removed the x86 Vista installation by removing partition and then recreate new partition and formatting it.
Then I tried to boot from Vista x64 DVD, due to 64 bit CPU instructions.
The load bar shows up, immidiately followed by "save mode" pop up even though no prior installation has been carried out or had been terminated.
Next I removed the Vista installation DVD and inserted Hiron's Boot CD to perform some hardware tests like memtest x86, hdd test, etc.
First time Hiron Boot CD booted into tools and I was able to perform hardware tests like Memtest 86, MoBo test, CPU, memory and hdd.
No errors found so far on the tested hardware.
Second reboot attempt with Hiron's Boot CD results in CRC error and every time the same CRC error.
Exchanging SATA harddisk with a identical IDE harddisk, results in "no disk found".
Exchanging SATA DVD with identical IDE DVD and putting back the original SATA harddisk.
Next attempt to boot from that IDE DVD drive results in bsod referring to possible Bios update.
Bios update carried out from R01-A3 to R01-B4.
There happen to be another Bios update available, R01-C2.
However, that one I did not try yet as it is not a official supported Bios update.
One of the changes with the Bios version R01-B4 is the available choice for another operating system.
Having the operating system changed into "other os" (for Linux boot CD) and then rebooting the system results in a black screen that presents "cmos checksum bad" and the choice for either, F1 which will bring you to the setup screen, or F2 which will reset to the default settings and then boot to whatever device has been set as first boot device.
That includes booting from Windows boot CD/DVD as default operating system.
Conclusion, booting from Hiron's Boot CD into testing files is not possible and ends with CRC error.
And the boot of a Linux distribution get stuck.
No Windows or Linux installation seems to be possible.
Windows ending in a safe mode even though no prior Windows installation had been carried out or crashed.
Linux installation get stuck.
Only booting from mini XP (from Hiron's Boot CD) is possible, which is virtually loaded within the memory.
So, what's the problem here?
Is it a driver thing, like nVidia Raid device?
I then would need a Vista Home Premium x64 recovery DVD, which I currently don't have.
Or is it something else?
Assumption is the mother of all f*ck-ups.
