Sorry for long thread title. :p

Two weeks ago I accidentally shut my PC down or sent it to sleep when I was in the middle of something. I'd had a long day and was tired and just hit the wrong option. :(

After a while I got the PC working again once the BIOS had reset itself to its default settings. It wasn't until later that I realised it had gone into IDE mode and not AHCI for my SSD on W7. I noticed this because the Intel RST logo wasn't showing the green tick to show that the RST service was running.

I set the BIOS to AHCI over the weekend but I've been having problems since then. When I got home today both Outlook and Excel crashed when I opened them. I had to forcibly reset the computer and when I did neither the mouse nor keyboard were working. I pulled the USB cables out and replaced them. I was then able to login but Outlook and Excel crashed again. So I restarted again and put the BIOS into IDE mode. Everything is now working, Outlook, Excel, keyboard and mouse! :p However I obviously want to get back into AHCI mode.

What do I need to do in the BIOS and Windows to get my PC back into a working AHCI mode? Motherboard is an Asus P5Q-E (LGA 775) and my SSD is an Intel 160GB X25-M I think. Is it possible that when I moved my PC to a new case about month back that I plugged the SSD into the wrong SATA socket and so AHCI isn't working properly? :confused::o
 
Thanks sunama. :) I'll try the manual fix and see how that works for me.

Update: It worked. Cheers. :) The PC was stuck on the glowing Windows icon for about 4 minutes but eventually I heard the sound of the Windows theme tune and was able to log in. All looks good so far!

Famous last words! PC hung when I tried to bring up the start menu. Restarting gave the old keyboard and mouse not working again issue so I'm back on IDE. I might give the memory sticks a test or even re-install Windows at the weekend. I think there's definitely something fishy going on here. :(
 
Yeah. That'll be a weekend job. I need to set the BIOS to AHCI before I install Windows? That's what's causing this problem? BIOS was set to IDE when I installed W7 so Windows ignored the AHCI drivers and now that I need them it won't use them.
 
Had this problem over the weekend.

The culprit was that stupid Microsoft Fixit tool for me.!!!! It actually removed the AHCI driver so the SSD would no longer boot if I selected AHCI in the bios. HAd to revert to IDE settings and that just made things worse - trying to insert the correct driver after is a nightmare !!

Resolved it eventually by restoring to a OS back up image that DID have the correct Intel AHCI driver

Did your re install work ?
