Sony Vaio BSOD on startup (CI.dll)

Hi Experts,

Just over a week ago, my Sony Vaio started to act funny and stopped starting properly...when it did finally load, all actions could take 15+ mins for a simple click.  The laptop was originally running Windows 7 home premium (64-bit OEM running on 8GB RAM).  I tried to run the repair via the recovery partition which appeared to have died as well.

I decided to format the C: and then remove the recovery partition etc and then reinstalled/upgraded the OS (Windows 7 Ultimate 64-bit) and the laptop worked fine for a day or so... However, when the laptop was restarted it appears to have got into a bit of trouble and now it won't start up, but instead gets a BSOD every time.

I've tried all the usual things:

  -  Last Known Good Configuration
  -  Safe Mode (doesn't load)
  -  Safe Mode with Command Prompt (doesn't load)
  -  Repair via Windows 7 disk
  -  Attempt to restore to earlier date (says there's no restore points, despite me creating one prior to the BSOD)

Each time the BSOD happens, it mentions CI.dll in the dump section... I've tried renaming and removing the dll but it recreates and dies each time...

Do you guys have any clues at all?!

Test your HD using the manufacturer's diagnostic tool. You'll find it on the UBCD:

If the test shows no errors you can also use that tool to lowlevel format or zero fill or write zero's to the disk (the different tools use different names for this). That should remove any mbr viruses etc., and after that you can try the installation again.

If this is a 'virus' shouldn't Kaspersky have picked it up?

I've used my Kaspersky IS 2012 disk as a rescue disk and performed a full scan (including all vulnerability scans) on the laptop and it came back clean...

Create a reliable backup. Make sure you always have dependable copies of your data so you can restore your entire system or individual files.

AV tools can never pick up all threats. The malware makers are just usually ahead... Also, I don't really know if kaspersky is any good, but I know that Symantec's AV products aren't worth their cost, and personally I use Panda's Cloud AV tool, which has a free version for personal use, and it is good.

I'll have a look at the links above when I'm back home (with the laptop) this evening.

One question - how do I get the files on to there when the laptop won't start?  Is this a case of burning scripts on to a disk or something?!

The UBCD is a CD you boot the PC from. The download gives an ISO file, and burn that to a CD using a CD burning utility like InfraRecorder, selecting "Write Image", and then selecting the ISO file you downloaded. Then use the lowest speed for burning the CD you can select. When finished, insert the CD into the Laptop's CD drive and make sure it is set to boot from the CD first:

and in the case i mentioned - they describe what to do : connect the disk to a working pc - then run TDSKiller

Unfortunately, the UBCD didn't resolve the problem and I couldn't get the laptop in enough of a working position to run TDSKiller.  Turned out, after a bit more digging on Google, that it was a potentially corrupt HD... I went out at the weekend and bought a replacement 2.5" SATA and it has worked a treat (so far).

Tried using the old HD in an enclosure as an external HD, but there's still some issues with it which don't seem to want to repair... so I've binned it!

Thanks for all the suggestions though, definitely something for future posters to try.
