Hi Everyone,
Apologies if this is a re-run of the usual 'black screen' posts on the XP forums; I've had a search through the site and as yet haven't found anything that solved the issue...
........................................................................... ...........
**System**
Dell Dimension 3000 (Celeron)
Windows XP Home edition SP2
(**To my knowledge I haven't got SP3, (through custom/selective updating of Win Updates), but XP may have subtly updated my system without my knowing it).
........................................................................... ...........
**Hardware changes made**
-512K RAM to 2GB RAM modules
-Wireless PCI card
(Both have been on the computer for at least a year and have been working fine)
........................................................................... .............
**Issue**
A few days ago I downloaded, mounted and opened a *possibly* suspect .ISO file and tried to open a .pdf from within it.
The system froze during this process, I restarted and then the following...
-Dell startup screen, followed by normal Windows XP splash screen as normal, then just a black screen with a moveable pointer.
-I have access to safe mode, but the same black screen occurs, (it has the usual "safe mode" text written around the edge as per normal and a moveable cursor).
-All four green diagnostic lights are on at the back of the tower.
........................................................................... ...................
**Attempted Remedies (not necessarily in this order)**
-Accessed and backed up hard-drive via PuppyLinux on a CD; makes me think that there's nothing wrong with the hard-drive, as it is perfectly accessible.
-Removed all USB peripherals and restarted PC; no changes.
-Tried restarting to 'last known good configuation' from (F8 Safe Mode Screen); no changes.
-Pressed shift key 5 times followed by 'bleep'; no changes.
-Taken network and wireless cards out and restarted PC without them; no changes.
-Removed CMOS battery to reset BIOS; no changes.
-Checked hard-drive connections were seated properly and generally tidied/dusted inside of tower; no changes.
-Tried bringing up Task Manager from Safe Mode (Ctrl+Shift+Esc); failed.
-Entered repair console from XP disk, then backed up and replaced user32.dll with the original, just in case Sasser virus was an issue; no changes
-Repaired windows using the XP disk. This changed nothing, other than the mouse cursor being made slightly bigger (?!)
-Tried 'fixmbr' through the Recovery Console; no changes.
-Scanned majority of the backed up hardrive files and Avast! flagged pagefile.sys as a virus. Scanned it using McAfee on another computer and it didn't find a problem. I've backed it up and deleted it anyway; no changes.
........................................................................... ...............
**Haven't Tried**
-Virus-Scanning the contents of the hard-drive remotely.
-I'm concerned about recovering from registry, (should it be corrupted), using the recovery console because according to this article (
Microsoft Website) it will apparently create usernames/passwords that didn't previously exist; due to OEM OS installation.
-Reformatting and Reinstalling OS; I would rather avoid a complete reinstall at the moment; although I know this needs doing soon.
I have a tendency to think that this is an easily-solvable problem because all components seem ok, hard-drive is accessible and XP loads normally at first.
........................................................................... .......................
...Sorry for the SERIOUSLY long-winded post. I realise I may have over-killed the problem with all manner of google/internet-forum solutions, but am at a complete loss of how to go from here
Does anyone have any ideas that I should try before finally reformatting?
Any help would be very much appreciated; many thanks.
