Windows 7: Pale Blue Screen with active cursor after logon & Welcome screen

Pale Blue Screen with active cursor after logon & Welcome screen

OK here is my problem.
I have a (my kid’s) HP Pavilion DV6-7002ax (aka dv6z-7000 (AMD-A10-4600M) using Win 7 (64) Home Premium and it has lately (last few weeks) developed a weird “blue screen with active cursor” hanging habit.

After you log-on and the welcome screen pops up with the spinning circle and then before the desktop displays it switched to displaying a pale blue screen, with active mouse cursor.
Up to that “blue screen” point, after logging on, the “boot” is slow but normal, based upon my experience with this HP Pavilion.

This blue screen delay/hanging lasts around 3 – 5 minutes and then the desktop loads and all is well.
I have searched the web and found many references to black and blue screens with active cursor related to HP Laptops but I have not found a real solution that has fixed my problem. Apart from just wait and wonder!

Suggestions I have tried include;
1. Scanned with Emsisoft Anti-Malware, Malwarebytes Anti- Malware, SUPERAntispyware (including in Safe Mode)
2. Specialty Scan with AdwareCleaner, rkill, TDssKiller, CCleaner
3. Registry Clean and Defrag with Wise Registry Cleaner
4. F5 > F8 > System Repairs Tools > Repair Startup (HP Pavilion has partition for System Repair)
5. F10 BIOS – no issues that I can find
6. Command Prompt > sfc scannow (System File Checker)
7. Completed Full Disk Check C: > Properties > Tools > Disk Check
8. Alt + Control + Delete when blue screen appears > switched to taks manager and after cancel back to either black or pale blue screen

There is a hotfix for this issue, with the issue being so wide spread one would think Microsoft would put it in an update. The hotfix is called Windows6.1-KB2578159, make sure to download the 64 bit version from Microsoft's site. This will hopefully fix your issue. At the hospital I work at we have had this issue a lot and just now found this hotfix, so I can't say for sure if it will fix your issue. Also make sure you have all the Windows updates installed. Hope that helps.

OK Every One,

Two maybe related things.

1) Normally our house hold wifi at the Router is turned on in the day time and early evenings as we have multiple devices and users using it. It is turned off at last one up bedtime.

This morning however it was off at the Router but on on the Pavilion when I booted the Pavilion and the pale blue screen was not there.

So I turned on the wifi at the Router and it was back. Wifi off gone, wifi on back?

Interestingly if I leave the Router wifi on and turn the wifi off on the Pavilion the boot is slightly slower with the desktop appearing with task bar, some icons then background and the everything compared to the Router wifi being off and the Pavilion wifi on when the desktop appears almost instantaneously after the welcome screen.

2) Based upon other advice I checked the registry (regedit) in HKEY_LOCAL_MACHINE>SOFTWARE>Microsoft>Windows>CurrentVersion>Run and HKEY_LOCAL_MACHINE>SOFTWARE>Microsoft>Windows>CurrentVersion>Runonce.

I understand that Runonce should be empty but in the Pavilion's case it includes this;

> ab NCPLuginUpdate REG_SZ "C\Program Files (x86)\Hewlett-Packard\HP Health Check\ActiveCheck\product_line\NC...

So, could it be the case that when connected to the wifi this HP Health Check Key is activated and causes the pale blue screen with active cursor, occasional twirling circle and several addresses to the dvd drive?

During the pale blue limbo phase the Pavilion seems to be doing something?

Interested in everyone's thoughts and I guess whether I should delete the HP Health Check Key from Runonce?

Turning off the wifi onboard the Pavilion or on the Router would seemingly work but would be avoiding the issue I think.

Onwards forever onwards.

It is possible that is the cause. We have been working with Microsoft on our issue here and we are not looking at the real-time malware protection. It seems that it is fighting with the antivirus at logon and causing this to seem like it is frozen but really it is just extremely slow. Booting into safe mode without issue will suggest that this is the case.
