So I had to finally do an upgrade on the cheap on my sons PC and I did a cost analysis and by giving him some of my old components and upgrading mine as well we saved quite a bit between the two.

Pulled out his old MB a real dinosaur p35, a pk5-deluxe and replaced it with a nice z97 PC Mate MB and a g3258 processor. I installed my old 8 gb RAM and my old AMD 5870 vid card, up from 4 gb and a 4800 series card.

This is his first build that he had anything to do with so I got him started and he went to it. Everything looked fine and we powered up. System went through post and the Windows startup screen (Win 7) came on for a couple seconds and
BOOM! A BSOD that lasted a tiny fraction of a second.

Reboot after reboot and the same thing. Repair failed. Restore failed. Safe Mode failed. "Last known good configuration" failed. Repairing the boot sector. Nada. CHKDSK- no. Hours and hours of nothing but nothing.

Then I cast my mind back years to a similar problem and on the off chance I looked at the BIOS and the hard drive was set to AHCI. I set it to IDE and voila! What a PIA.

Anyway I downloaded a tool from MS which loaded the proper drivers and registry changes and now we're AHCI and booting.

I hate builds.

Glad you got it working. I hate that "Oh crap, what have I done" feeling when flipping the power switch and I get nothing, or worse, an burning electronics smell.

Cool that you got it figured out, but that shouldve been a 5 second fix.............

Though I deal with issues like that all day, so I guess that isnt really fair :p

The power supply and the vid card wont last. I would have just bought him a new laptop

IDE mode sucks. Reinstall windows in AHCI mode.

In fact, after the repair failed, a reinstall would have been my next step.

Yeah, work with enough systems and you end up memorizing the 7b error means Windows cannot access the hard drive.

Halfway through was thinking "AHCI." Had the same issue when I did my last motherboard replacement. Glad you got it fixed.

the 5870 is still a decent low-mid range card. A laptop with that much graphics power would cost $1000+. Also, why do you say the PSU will fail? And even if it does, that's what $50? Still cheaper to upgrade desktop and replace a few parts than buying a laptop.

I have had bad luck giving people old stuff. the parts fail soon after i give it to them it seems

Updated my mb bios the other day, on the reboot win 8 gave me a lite blue screen with a :( on it and a message then turned off. After doing that twice I booted into bios and saw it had turned ahci to ide causing a failure when it tried reading the drive.

I would think that OSs ought to be smart enough to treat HD's like boot sequence orders. If AHCI fails automatically try IDE and report the event after boot, assuming it works.

An OS could be programmed with that logic, but the motherboard/storage controller is what determines AHCI/IDE mode, not the OS.

I think this specific problem is in Windows, though, or in some interaction between Windows drivers and the hardware. At least up to 7 you can't just switch back and forth between AHCI and IDE mode. My memory is hazy on it, but I think it basically uses a different low level hardware driver, and you have to make the choice at install, or hack the registry afterward. I never quite understood what the benefit was since I never saw a difference in performance either way.

Yeah, it spazzes out, I had to do a CMOS reset on a 7 system the other day & forget to flip back to AHCI, it kept blowing up at boot until I remembered that trick :p

For those who don't know, 0x0000007B is INACCESSIBLE_BOOT_DEVICE.

Probable causes:
1 - IDE/AHCI
2 - Dodgy storage driver
3 - your disk is dying
4 - the file system on your disk is a bit mangled, chkdsk /f /v /r from safe mode / boot CD should do it.

Of course, 4 can be a symptom of 3.

There is a way to switch between AHCI and IDE through registry changes. Of course you have to do that before making the switch.

I've encountered the old AHCI / IDE switch BSOD problem many times before. You would think Microsoft would come up with a contingency plan for a configuration change like this.

Who you calling dinosaur?!
*looks at his GIGABYTE GA-P35-DS4

Making me sweat a little...

I was working on my system and I am the one with the p35 board, and it's been a good one. I'm keeping it for backup so you don't have to feel so old. His was a LGA 775 board almost 10 years old.

I just thought it somewhat funny to get something like this

Nice! How did you get that? I'm guessing that Windows was installed in the VM, then a setting was altered so that the emulated system wasn't ACPI capable, or perhaps the emulated processor was switched to a 32-bit one? Or perhaps someone did an ill-advised HAL switch :)
