The manual for my new Asus P8Z68-V (i7-2600K) says on page 4-1:
"This motherboard supports Windows XP/ 64-bit XP/ Vista/ 7 / 64-bit 7 operating systems...."
Let's not argue about why I want XP. I need it. I have already tried W7 Pro with XP Mode, but XP Mode cannot run my old program that has run on several direct XP builds in the past.
I have tried two separate XP 32-bit CDs, two different DDR3 sets (Corsair 4GB and Gskill 8GB, both underclocked), two different hard drives (Hitachi 1TB, Western 250 GB), NTFS and exFAT formatting, and several combinations of the above. Every hard drive was freshly formatted every time.
In every attempt, after a few minutes, I get the following:
"A problem has been detected and windows has been shut down to prevent damage to your computer.
"If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:
"Check for viruses on your computer. Remove any newly installed hard drives or hard drive controllers. Check your hard drive to make sure it is properly configured and terminated. Run CHKDSK/F to check for hard drive corruption, and then restart your computer.
"Technical information:
*** STOP: 0x0000007B (0xF78D2524, 0x00000034, 0x00000000, 0x00000000)"
My experience with Asus support is that it is a total waste of time to ask.
Suggestions please.
