Boot problem (can boot only once in 40 tries)

I have:
- P9X79 WS motherboard
- Intel i7-3930K
- Gigabyte GTX 970 Mini
- (also RME HDSPe AIO audio card + Sunix UFC2412 PCIe Firewire card)

My problem started perhaps two years ago when I started to feel there's something strange with my bootup sequence. It randomly took a long time before the Windows 7 loading screen appeared. Gradually I started have more severe boot problems and maybe even some blue screens. Recently I changed my case and improved my temperatures. I had a too hot case for a long time, somewhere between 70-85'C. Now, after the recent changes my boot problems have gotten worse and worse. The timing may be a coincidence, though.

Anyway, the problem now: Everything is perfect when I am booted into Windows 7. No significant temperature problem, no bluescreen, everything is fine. Even standby and resume work quickly and perfectly. But if I have to turn off the computer completely, that's something to avoid at any cost. Nowadays I have to reset (hard reset or ctrl+alt+del doesn't matter which) 40 times before I can get past the Windows loading screen. It takes quite long, maybe 45 seconds, and then it typically gives this reason for failure:

File: \Windows\system32\winload.exe

Status: 0xc0000221 (file possibly corrupt etc.)

or the same with ntoskrnl.exe. However, there are about 15 other files that may be the "cause" as well, it is totally random. Then, after 40 times trying, I suddenly get past and everything is fine.

I have tried pretty much all possible BIOS settings (which is a total mess IMHO in this mobo) and also tried switching TPU and EPU mobo switches (although why touch it if it used to work). I have removed all USB devices. Nothing helps. I have done a relatively comprehensive memory test so I doubt there's anything wrong with my memory (8 x 8 GB RipjawsX). I really doubt it would be hard drive either (I already had the same problem with previous hard drive too).

What is the most possible culprit here? Since there are no problems after boot is successful, what part in the computer is "sensitive" at bootup, other than whatever is involved with BIOS? Because I think BIOS works fine (whatever small problems I find with the BIOS settings, they are probably just bugs).

It'd be a bummer buying a new motherboard and still encountering the same problem..

Try look in eventlog. See if you ahve issues there now and then. Could be a storage issue.

I smell storage issues too. Leaving just boot disk and swapping SATA cables could pin point the issues real soon. Heck i would probably try other sata port as well.

ShintaiDK, by eventlog do you mean Event Viewer / Windows Logs / System? There I could not find anything helpful because the time starts at somewhere when the Windows is already probably loaded (which is when everything works already).

Once I have to turn off my computer completely next time, I'll try booting onto another hard drive to determine hard drive health (it takes one hour and 40 reboots to boot up this thing now..). CrystalDiskInfo says "Good (100 %)" on my C: drive (which is Samsung SSD 840 EVO 1 TB), but that probably doesn't rule out the cable, at least.

Jim, if you've run memtest and your memory is fine, and if it works perfectly after it's booted then your CPU is probably fine (probably GFX card too given your problems predate it). Maybe as others have said you have a serious problem on the I/O side of things:-

- Can you actually see your SSD / HDD's in the BIOS screen (pre-boot)?
- Faulty SSD? Does SSD work on another PC in an external 2.5" USB to SATA caddy (do you have one for an external backup drive you could temporarily swap it around to test)?
- Faulty SATA cable? (maybe unplug optical drive & test that cable)?
- Faulty SATA controller or ports on mboard? (Test in other ports?)
- Reinstalling Windows? Even if you don't go through with it, can you reliably boot say a Windows install DVD and get to the disks detection screen to see the SSD listed (even if you then cancel)?
- Have a spare HDD lying around you can test a new Windows install on?
- Can you boot from any other device (USB stick, DVD, etc)? If so, can you see your SSD if you boot to say a Linux Live CD of some kind?
- Problem with RAID BIOS / drivers? (There was one version of an Intel SATA driver that refused to boot unless BIOS was in "RAID" mode (even if you didn't have a RAID setup)).
- Tried reflashing BIOS?

I've no real answers, just throwing some ideas out there to test and maybe narrow it down?

What PSU do you have ?
I had one system that wouldn't boot all the time, and it turned out the PSU was dieing.

I think that it could be this.

OP, when you say it won't boot, does it POST, and then say "ERROR LOADING OPERATING SYSTEM"? Because that error would point to storage being the problem.

If it doesn't POST at all, then the problem could be the PSU.

Hi all! Thank you for great answers. Sorry, I haven't yet turned off my computer since yesterday, I can boot to another hard drive, that will tell much.

But since you asked, here are some answers:
- I am using the booting C: (Samsung 840) on Marvell's controller at the moment.
- There is no problem with POST that I would recognize. It POSTs fine and gets stuck right before "Starting Windows" or at "Starting Windows" (the Windows logo doesn't come up, if it does, it will also boot).
- The error message is as I said, different each time. Sometimes just "unknown error" without a corrupted file.
- My PSU is Corsair AX650W (2 years old, been very hot)

And if you are going to change SATA ports, do try using a different cable as others have suggested. I had a big problem a couple of years ago and was pulling my hair out trying to figure it out. I didn't even consider the cable because I thought they were so simple that nothing could go wrong. Well, I was wrong about that and the source of all my problems was a bad SATA cable.

Ok now I have pulled all my hair incl. scalp out several times, but perhaps it's time to start growing the hair back. Indeed, this ridiculous thing called Marvell controller seems to have been the culprit. I just put my two SSD drives onto the Intel SATA ports and put two HDDs onto the Marvell crap ports. Everything seems to be fine now. Ridiculous.

The Marvell port does have a sticker, but it only says "SSD Caching".

But thanks all! :awe::thumbsup:
