| 525929 | 2007-02-19 21:49:00 | I am currently experiencing two problems on my home PC, but I'm not sure whether they are related or not. 1. When I turn the computer on, almost every time it will go through POST, display the Windows XP splash screen for a few seconds, and just after the keyboard lights flash, it will die with a BSOD with the following details: PAGE_FAULT_IN_NONPAGED_AREA STOP: 0x'00000050' (0x'FFFFFFE8', 0x'00000001', 0x'804DA07F', 0x'00000000') When I press the Reset button on the machine, it may or may not start successfully - sometimes it can take a dozen or more attemps to get it to start without the BSOD. (It will always start in safe mode which suggests it is NOT a hardware issue.) Web searches imply that the STOP error code indicates a driver issue. Using MSCONFIG to try and narrow down the culprits highlighted the second problem. 2. Logged on as administrator using MSCONFIG, every time I press APPLY or OK, I get a message saying "Access denied. You may need to log on as an administrator etc." Oddly enough, the changes appear to be applied. The same message appears if I try to make any changes on the Services screen. PC Details: 2.8GHz P4 running fully patched Win XP Pro SP2. Leadtek FX5900 Video card - drivers from Dec/Jan PC World disc. These problems have only started since I did a complete format/rebuild of the PC in January. The only significant software change during the rebuild was replacing Nortons AV 2003 with NOD32 (courtesy of PCW subscription). Initially I had suspected a flat CMOS battery, but now that has been replaced and the problems still persist. The most confusing thing I guess, is that it tends to start from pressing RESET on a BSOD, but invariably will not start from a cold start. Any help appreciated. I don't really want to go through the rebuild again, but feel that may be my only option. |

| 525930 | 2007-02-19 22:10:00 | By access denied in msconfig, do you mean msconfig wont open? Does it boot into safe mode? Does regedit and task manager open? I would uninstall the video drivers, and get the updated drivers from the Nvidia site. Use ccleaner and see whats in the startup, or / and tell us whats there. |

| 525931 | 2007-02-19 22:27:00 | By access denied in msconfig, do you mean msconfig wont open? Yes, msconfig will open, but if I select/deselect an item in the startup list, for example, when I click Apply/OK, I get the message. Ignoring the message and exiting msconfig appears to keep the changes however. Does it boot into safe mode? Does regedit and task manager open? Yes. Task manager is fine, haven't tried regedit. I would uninstall the video drivers, and get the updated drivers from the Nvidia site. I should have tried that by now but haven't. TBH, it is the one I suspect most. Use ccleaner and see whats in the startup, or / and tell us whats there. It's quite freaky when you are editing a post that I am replying to and the quotes keep changing. :waughh: |

| 525932 | 2007-02-19 23:19:00 | 0x00000050: PAGE_FAULT_IN_NONPAGED_AREA Requested data was not in memory. An invalid system memory address was referenced. Defective memory (including main memory, L2 RAM cache, video RAM) or incompatible software (including remote control and antivirus software) might cause this Stop message, as may other hardware problems (e.g., incorrect SCSI termination or a flawed PCI card). |

| 525933 | 2007-02-19 23:22:00 | Doesn't really narrow it down. As I said, the PC has NEVER faulted when starting in safe mode, so reduces the likelihood of hardware. | Miami Steve (2128) | ||
| 525934 | 2007-02-19 23:35:00 | Looks like Bitdefender, Zonealarm, or some HP software (specifically a security update for this printer - HP PSC 1410 printer software), can cause this access denied error. You're not the only one who has this prob (www.techspot.com) Is this the error/message you're getting? Also you shouldn't disable services in msconfig. |

You're not the only one who has this prob (www.techspot.com) Is this the error/message you're getting? I have searched for solutions to the "Access denied" problem and there were just too many variations. I never saw the one you found. I'll follow the steps in there to fix my problem. (PS I bought an HP PSC 6180 printer in January. :D ) Also you shouldn't disable services in msconfig. I didn't actually use msconfig to enable/disable services, I just tried to see whether that was affected too. However, why should msconfig not be used? |

| 525938 | 2007-02-28 21:31:00 | Here is an update to the problems I was having. 1. The BSOD - appears to have been resolved (fingers crossed) by uninstalling the video drivers and installing the latest ones. 2. Access denied problem - I emailed HP support and got a response with a link to a utility to correct access problems. I ran the utility and it didn't help. There next suggestion was to uninstall the HP software and see whether the problem remained. I did this, but the HP services are still in the services list, and the error is still there. How do I remove services? I am unable to disable the services through services.msc - Error 05 - Access denied. I then thought I would create a new admin user to try that in case the current profile was corrupted in some way. It made no difference. I noticed that administrator was not in the list of users so I tried to create it. Got a message that the account already exists - why can't I see it on the Welcome screen or in the User Accounts control panel applet? If I reinstall Win XP using the recovery option, what is the likelihood of this fixing my problem? |
