Why Does Windows 7 Freeze When Try To Switch To AHCI Mode
Jan 1, 2012
I changed the appropriate setting in the registry. (msachi > start: 0) Then I changed the setting in my motherboard and Windows froze upon starting up, and my system rebooted.
The thing is, I changed it to AHCI before. It worked fine! I then switched back to IDE while trying to fix a problem with eSATA detection (turned out to be a faulty cord), Now I can't switch back! Sigh. I really would like my eSATA to be plug and play.

anyways, my main drive is a RAID 0 with Vista x64, but I have a second HD that is a SATA 250GB, which I installed Windows 7 on. The only way I could get install to work was to switch my BIOS to IDE mode rather than RAID. I would of course though, like to be able to access my Vista drive from Windows 7 (and more importantly, not have to switch between IDE/RAID mode at all in the BIOS, it's a pain).
Now, the one odd this about this all is that the drivers I have for Vista (x86/x64 drivers) for this mobo's RAID controller WORK when loaded on installation to identify and install to the drive, but seem to not load or not work in any way once the first reboot on install occurs. Maybe this is because I installed from within Vista x64, though.
(Incedentally, my motherboard is an M3A Asus, using ATI's SB600 for a RAID controller)
I've tried loading the drivers from within Windows 7 while in IDE mode, but the install program won't let me. At first it didn't allow because of version restrictions, but then I altered the ini file to get around that, but it encounters some sort of error when installing and quits.
Any help that can be offered, would be grateful. I realise it's a beta and not a real release, so I can get past the BSOD from my odd setup, and I really am enjoying playing around with it so far. Very very impressed.
Edit: Just in case anyone thinks of suggesting me to right-click the inf file and install that way, already tried, won't allow for it.

Everytime i want to swap hard disk with different OS, WinXp(IDE) to Windows 7(AHCI), i need to do change some hard disk setting on BIOS. Is there any way that i can do to make both hard disk with different OS compatible on the desktop PC without change any setting on BIOS everytime i change hdd? Is there a way to make WinXP IDE mode to run under AHCI mode?

First thing, my build:
Board: Gigabyte GA-P55A-UD4
CPU: Core i7 870 @ 2,93 Ghz
Graphic: Sapphire AMD Radeon 8670 Mushkin 2x2Gb Red Culvert Kit @ 1600Mhz CAS 6-7-7-18
Seagate 320 GB SATA II HDD + WD Caviar Black 1TB SATA III HDD
Running: Windows 7 Ultimate
Trying to install: Windows 7 Ultimate
PSU: LC Power Arkangel 850W
I have Windows 7 Ultimate installed on my 320 Gb HDD and everything is running ok. I just bought a WD Caviar Black 1TB SATA III disk and I want to install Windows 7 there, since the disk is faster. Here's what happens. When I connect the disk (it is connected GSATA 3 connectors), the disk will be recognized in bios and in Windows, but wont show under My Computer. I figured it must be some software bug so I formatted the disk in diskpart (clean format) and installed Windows 7 on it. At that time the GSATA 3 interface was set to IDE mode. It ran fine but after installing a big batch of Windows updates, the system hung at windows startup screen. After restoring the system to a previous state (i.e. before the updates), the system booted up normally.
I didn't know what was wrong so I formatted again, and this time I set the GSATA 3 to AHCI mode, since I realized this is a better option. When installing in AHCI mode, the computer expands the windows files but when the system is restarted, I get a BSOD (code Stop 0x000000B4 video driver failed to initialize) at Setup is updating registry settings. I really want to use the AHCI mode, but I cant get the system to work in IDE either so its really a bugger. I have no idea what could be causing this as the system works fine when using the other disk. Can the BSOD be caused by the HDD? Anyway, I really want to start using the disk. I have tried installing Windows 7 from a dvd as well as from a USB key.

i'm working with a new pc build that uses a 60 gb ssd for its boot drive, and which is also reusing some "old" sata hdds for storage.
at the time i installed windows 7 ult 64, i had only a new ssd plugged in, and the bios was set to ahci mode. the installation went fine and i was able to boot into windows afterwards without issue.
then, i connected a wd caviar black sata hdd to use as storage, with the ssd being the boot drive. with both of them connected, windows will not get past the starting windows screen.
i made this video of the program before i understood that it was a drive controller issue: startup problem - Internet in it, you can see that windows boots fine in ahci mode with just the ssd plugged in, but that when the backup sata drive is also connected it doesn't get past the starting windows screen.
for the record, this caviar black hdd was my previous boot os, and it also has a windows 7 install on it (which i've renamed the base folder of), but it is not booting from that hdd. also, i have tried the same thing with other "old" sata hdds that do not have any previous windows install on them, and the result is the same thing which is shown in the video.

i have an ASUS M5A88-M motherboard, and a Western Digital WD2503ABYX HDD. i am trying to make that drive work in AHCI mode, but when I try, the disk won't boot. i think the HDD is AHCI compatble, tho not certain. i went into the registry to set a value=o for the relevant AHCI parameter, but no luck. if i need a full re-installation of Windows 7 64-bit, does it prompt me along the way to set the mode to IDE or AHCI?.

I created a system image on an AHCI system, then I replaced the hard drives & re-imaged the system. Now Windows won't boot in AHCI mode, it has to be it IDE mode. Why is it not booting in AHCI mode?

I successfully installed Windows 7 64bit in AHCI mode on a PC with 3 new 3TB Western Digital WD30EZRX Caviar Green hard drives.Then I installed "Intel Matrix Storage Manager Driver [v8.9.0.1023]" & as soon as Windows restarted after installing it, Windows would not boot, & will now only boot in IDE mode.In IDE mode I have to do a system restore to the point before installation of "Intel Matrix Storage Manager Driver" to be able to boot again in AHCI mode.

Can someone hit me with a link for manually installing the AHCI driver and switching the OS mode for the storage controller.
If I remember right, this is just putting the driver in /sys/drivers, running a script, and making a registry change. Then you reboot, change the motherboard setting, and then install IMSM after the OS comes back up. I don't remember the script, or if it was just a reg edit, etc.

I'm trying to do a startup repair of Windows 7 x64 on an SSD but can't boot from the CD-ROM while in AHCI mode. I have set CD-ROM at the top of the boot order in BIOS but this is just ignored and the computer boots from the SSD with the knackered version of W7x64. I read somewhere that when in AHCI mode, the BIOS boot order may include "CD-ROM" but it's not the real device anymore. I tried looking for the CD-ROM by its manufacturer name in the list under Hard Drives but it's not there either.So just how do I go about booting from the CD-ROM in AHCI mode? No problems booting if I set the BIOS back to IDE mode, install Windows 7 and then do the registry hack to install the AHCI drivers, but I'd like to be able to boot from the CD-ROM in AHCI mode.
P.S. I have a Gigabyte GA-MA78GM-US2H motherboard and am using the latest BIOS version (F9D)

My motherboard is a Gigabyte Z68XP-UD3 Revision 1.3, my OS is Windows 7 Professional 64 bit, my HDD is a Seagate 1.5tb, and my SSD is an OCZ Agility 3 60gb.
So i was using Intel Smart Response technology with my SSD for SSD caching, everything was pretty much working fine. The other day i flashed my bios using @BIOS without properly disabling my smart response configuration, which i probably shouldn't have done and i won't do again. When i rebooted, Intel Rapid Storage technology was acting up and when i tried to open it, it said "IAStorUI.exe has stopped working". After that, i uninstalled the program and tried to re-install it, but during the install it said "This computer does not meet the minimum requirements for installing the software." After a little research, i found out that it meant that my bios was set in IDE mode instead of ACHI mode. I am not sure what the mode was before i flashed my bios, but it was probably some sort of raid that it used for SSD caching. When i went into the bios and switched from IDE to AHCI, windows would blue screen after performing a few seconds of the boot logo. I switched back to IDE, and did some research to find out about the "Start" registry in HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesmsahci. I switched that from 3 to 0, and windows was able to boot into AHCI mode and automatically got drivers. Then, i tried re-installing Intel Rapid Storage technology. It was able to install, and i rebooted my computer. It blue screened again on the same part of the boot logo as before. I had to switch back to IDE mode to get it working again. Then, i got new chipset drivers from Intel's website, which didn't help. The registry that i changed is still set to zero, but it just won't successfully boot with AHCI like it did the first time i changed the registry. I am very stumped and i dont know what i could do to make it work like it did before i flashed my bios. My friend recommended that i should reinstall windows, but then i would have to go through the trouble of getting everything back and i think there should be some way of doing this without reinstalling the os.
The bottom line is that windows blue screens when the bios is in AHCI mode, even though i have the registry that should fix that and that did fix it on one boot set to zero.

I'm installing Seven on a WinXP machine and completed the install, but forgot to change the SATA setting in the bios from "compatibility mode" to AHCI. Now when I change it, windows gives me bluescreen on boot.I'm dumbfounded that Windows Seven startup repair can't fix a problem this simple, but it completely failed, wasn't even able to find a problem.I was thinking it might be easier to just reformat and begin the install over again, or startup in safemode and install the intel SATA drivers... assuming it will let me boot into safemode with AHCI enabled.ps. On the other computer (different thread), I'm going to wait till I have several hours of uninterrupted time, in case I need to begin over installing all the windows versions one at a time. I'll reply with any success/failure on that thread later in the week.

A strange problem, nothing critical, but I found it annoying that my optical sata drives will not boot from a bootable disk when in AHCI mode in Bios. If I switch the drive mode to native IDE then I can boot just fine from either of the Opitcal Sata drives.I have done some searching and found this has been a problem out for some builds/MB in the past but you would think with a new MB and Sata controller and such this would no longer be a problem.If you look at my specs you will see the Gigabyte MB. The documentation is fuzzy on the sata ports. There is a setting to put SATA port 4/5 into some kind of IDE support mode. I currently have the slots 0 - 3, used for all the drives. 0 & 1 for HDD, and 2 & 3 for the optical drives,wondering if I use the 4/5 slots for the SATA and set the bios to the 4/5 ide support if this might solve my little problem.

If the BIOS setting for the hard drive controller is AHCI it will not recognize the drive. (This was the default setting in the BIOS), If changed to IDE mode it recognizes the drive but come up with an "No operating system detected" message. If the hard drive is installed in a second lap top it works fine. If another hard drive is installed it works fine in AHCI mode. Only the combination of the original hard drive and the original lap top wont work.

Recently purchased a Rosewill 2 port KVM switch so my laptop can use my main monitor, keyboard and mouse. Since hooking it all up, the main PC will not go into sleep mode on it's own after 10 minutes of inactivity it had previously (which I had it set to).I removed the switch, and it went to sleep after 10 minutes, reinstalled the switch and it stayed "awake". I can manually put it to sleep via either the start button, or via the sleep button on my keyboard...but it won't on it's own.Strange thing - the monitor will still turn off after 5 minutes no matter if the switch is hooked up or not.

I have the GA-EX58-Extreme Board and have just installed the pre release of Windows 7 7600 64 bit. Normally i have experience to get the BSOD when in staling with AHCI active in bios so i change to IDE mode. Installation went flawless and also the change to AHCI mode on Intel ICH10R controler went normal.
As always i got problem to change the J micron controller to AHCI and of cause i got the BSOD again. I installed the latest R1.17.48.16 driver and tryed again but no luck. Can some tell me what i am doing wrong. ? I have a hardisk and a dvd drive attached to the J micron Sata connection.

We have Windows 7 x64 and needed to run older QuickBooks software. I installed XP Mode and everything works great except when it comes to printing. I installed the HP LaserJet 1320 USB printer and used TSPort 001 and everything worked. The next time the user stated XP Mode the TS port 001 was inactive. I switched to an active port TS008 and printing worked again. The next time the user started XP Mode the TS port TS008 that was just active gets switched to inactive so I have to change it back to the original port TS 001 and then it works again.

I am still having bug and freeze problems on all of the computers that I have been testing on since the first release in November.
I am currently testing both x64 and x86 versions on 4 of my PC's and still having minor bug issues, and the major freeze problem.
I do not Just use my PC's for e-mails, browsing the web and gaming. I primarily use them for Engineering Design Work and they need lots of resources to operate efficiently. My primary Base unit is the one I do most of my work on and the Most efficient Operating system on it is Windows XP x64 (sp2) and customized. (Not the Basic install of services and registry sets).
The freeze issue is random and it happens when my PC's go into sleep mode. Some times the will wake up normally, but way to often they will not wake at all, I have to force re-boot. And no error logs related to sleep mode issues, only the E-ID 41 (forced re-boot). This has happened on all the releases from 7000 to 7127, and now 7600, the releases from 7137 to 7229 never had this problem. And this has happened on all my test PC's including Laptops and Desktops.
I have tried many changes in settings for Power Settings (Advanced), Network Adapter Settings, Monitor settings.
Ideally I want my Network Adapter to stay Active on my main box so I can access files from my other computers any time I need them, I want my HDD's to go to sleep when not in use so they will live for a while. and My Monitors to shut down when not in use.

When system goes to sleep longer than a hour and you wake it up the bottom third of the screen freezing. The top 2/3's get split like window pane a when you scroll the top 2/s's will scroll but the bottom 1/3 will remain as it was before sleep. Also the bottom third wont have any hover icon effects though icon will still work, the task work as intended. If I restart the programs the will work fine but windows has to restart for icon hover effects to work.

I walked away from my computer last night with only Google Chrome running, and 2 tabs: AOL mail, and Facebook/FarmVille. When I returned to it, the browser froze. I hit cntl alt del to close the program. Things still seemed slow after everything was closed, so I tried a reboot. However, it won't let me past login. I get the word welcome with the spinning circle and nothing else.
In safe mode, things were fine, just a little slow. I scanned with Webroot twice, and nothing was found. I was browsing for suggestions last night and Tried sfc/scan now... That came back normal too. Another suggestion was some anti malware programs, downloaded Nader safe mode with networking. That's how I learned I get the same freeze at login with that startup.
I'm not a computer nerd but use them regularly and am willing to try some things before taking it into a shop, so I'm open to suggestions. Last month I contracted Trojans and while it was at Best Buy being repaired, they realized the hard drive was going bad, so I have a new hard drive, if that makes any difference.

My A200 has been upgraded to 4GB RAM, and Win7, worked fine for a while, then started randomly freezing with weird screen stuff (video not displaying properly). Power off only worked. Much frustration and removal of progs later, tried on safe mode - works fine. Safe mode with networking - works fine. Can plug it in (surefire way to get it to fault normally) and in safe mode it works fine, in normal mode, immediate fault.
Thought perhaps a horrible malware, did clean install from disc of win7, no change (except now, coz I deleted all the Toshiba drivers, the dvd drive is noisly lol). Can't load progs to run the damned thing properly because it won't run in normal mode, only safe mode. Tried formatting the hdd, but it won't let me (partitions) which I thought were reformatted during a clean install anyway?
Haven't tried changing the charger yet, because it works fine in safe mode, so I thought probably a software issue? Have tried minimal or "clean" normal boots, freezes immediately.

Whenever I switch user accounts the computer will start the switch and then lock up with a display message that says no signal on the monitor. It happens if the computer has been running for hours or only a couple of minutes. I have to shut the PC off and leave it off for 20-30 minutes. I can then restart and enter any user account. But if I try to switch user or logoff and pick a different user the whole cycle begins anew.

Im tryin to get my 64GB Mtron SSD runnin with Windows 7 but I can't get it to show up in the installation process. It shows just fine in the BIOS, in device manager, in My Computer and in Windows Disk Management, in fact I can even use it as storage but for some reason It will not show up as a disk to install Windows. I have tried as IDE in BIOS and AHCI and in AHCI mode it will not show up in the BIOS at all or anywhere, I can only get it to show in IDE mode. It has been fully formatted and has had Windows 7 on it here recently (had to reformat due to some speed issues). Does anyone know a way I can get Windows put back on, preferably in AHCI mode cause Im stuck with a Thousand dollar drive thats good for storage only
My board is the Gigabyte GA-EP43-UD3L with BIOS F8 which according to their site is the latest one. Processor Q8600 and 4GB of OCZ Flex RAM...

This happened when I was booting today after turning it of last night after using it successfully since I bought it.The AHCI Drivers are corrupt.Windows won't load, it is stuck on the load screen.Trying to repair windows using the various F8 options doesn't work because they won't load either.Even the recovery partion won't load, it's stuck on the Acer E Recovery screen "please wait" and it is stuck for several hours on this.Now, in BIOS, when I change to IDE mode, it will load the various F8 options like trying to fix windows, but the problem doesn't solve itself. Also, the recovery partion does load, but it only gives me an option to install everything to factory settings, not just reinstall windows. However, Windows 7 won't actually boot on IDE mode, so I can't actually get into Windows 7.Therefore, my AHCI drivers are corrupt while the IDE ones are fine. How do I install fresh AHCI drivers to fix my corrupt ones from a USB stick? I do not have a windows install disk, it is all on the recovery partion/recovery disks
