Hello, please direct me to the correct topic in case I have posted in the wrong place.

I have recently reinstalled WinXP Home Edition with SP2 on AMD Athlon 64 2x with 2GB of RAM [at the moment the memory does not appear under My Computer properties and the system is impossibly slow].

After reinstalling most of the programs the computer seems to have developed some registry problems that have became apparent when reinstalling an AntiVirus program. Install is denied to the Administrator.

Service Pack 3 has been trying to update but after download will not install properly due to local administrator priviliges denied, although I am logged as Administrator on a standalone computer. I have also tried installing SP3 after dowloading the complete file but to no avail.

I have performed several AV and Anti Malaware scans in the last 48 hours, both online and off, CHKDSK and Defrag on all disks. System, drives and memory all appear to be error free.

The registry was reported to be too large to be backed up so I tried a compacter/defragmenter. All attempts have been unsuccessful. I also uninstalled [with uninstall tool] all AV instances. Windows Live OneCare scan tool gives error 0x04601C01 but I found no help in the Microsoft Knowledge Base.

Microsoft Baseline Security Analyzer warns that Windows Firewall tests cannot be done due to an error(0x80080005) occurred while scanning for security updates.

I have not yet attempted to run the update in Safe Mode nor have tried editing the registry which appears to have a lot of clutter from programs that have been installed/uninstalled over time.

At the moment the PC will boot up to a black screen and I have to manually run explorer.exe to get to my desktop and Start button does not respond.

Please do not suggest I reinstall XP as this has not resolved the registry issue in the past, rather it seems to have aggravated it.

Perhaps unrelated I have lost all my backed up data on external Hard Drives [Maxxtor 320GB and Seagate 500GB] twice in 4 months due to excessive tremors from a railway line.

Please advise on what scans I can perform to assist in your diagnosis and whether I should take any other action before running a HijackThis log.

Thank you.

What type of install did you do, Full or Repair? Honestly, if it were me I'd start over with a fresh install. Did you do this reinstall with an XP CD or the computer manufacturer's recovery CD's and were they the correct ones for your computer?

It sounds like they have tried to run windows as a repair disk from within windows, not by booting to the cd?

thanks for the replies...it has taken approx 7 hours to get again to the blue screen I had yesterday, as usb mouse and keyboard were not recognised. i have attempted safe mode, this gives: "the following file is missing or corrupt:\windows\system32\config\system ...select "r" to start repair using original CD-ROM."
this is what I have attempted, booting with the original CD, otherwise I got complete failure to even start Windows, black screen, zero fuctions and after checking power supply, cables, memory, monitor and had to reset BIOS and CMOS, tried 'Last Known Good Configuration' all to no avail.
it's impossible to do a HijackThis report as I don't even reach the Start screen, and I am reluctant to do a clean reinstall as I couldn't back up the registry as explained before. I know my files are OK on secondary drives but I kow I'd lose all the Outlook data and I have some work that cannot wait in email folders and drafts there... HELP?

boot to the cd, skip the recovery console and install windows using the repair option as shown in my link

you may have to fight the infection with tools downloaded from another computer and staying out of normal mode

if you can ever get it fixed enough, grab the outlook data

I have some work that cannot wait


have you seen the wait times in the hijackthis threads?

I see the XP screen and then the dreaded blue screen of death...work should have been sent yesterday, now is already too late. depressed. if I can I'll use my maxed out credit card and buy a new PC ad rescue the main drive? but how?

ask around, there are a lot of places that grab your data and if you have a legal cd and certificate of authwhatever
they can reload and have you up and running

it is cheaper to buy a new computer but then you have that problem of that data, here again it's not a beginner task

back in the olden days of dummies for dos and windows those books stressed having a pc guru, a friend you bribed with beer
chocolate, home cooked meal whatever

well, are you suggesting I offer personal favours to rescue lost work that already cost me thousands of pounds? :thumbsup: I have worked out how to reset the CMOS but then what? here's what I'd like to try next: http://support.microsoft.com/kb/307545/ "How to recover from a corrupted registry that prevents Windows XP from starting" but how do I get the XP disk to start the machine so I can select "r" for recovery?

thank you Bakky! Finally some hope! I will try the Recovery Console as soon as I manage to burn a CD on this clapped out emergency laptop that has a few too many keys missing and no floppy nor USB 2...and I mentioned my work not to get sympathy but because everyone keeps telling me to reinstall/reformat and I can't afford to! ...dinner is on me if you're ever in London! :thumbsup:

Implementation of a backup strategy...would eliminate unnecessary worry about what is on a system.

Things go wrong all the time with computers...not all of them can be solved by retaining the files which were on the system when it went on the blitz.
