All I want to know is what does that error message mean and what can I do to correct it ???
The answer, unfortunately is NOT as simple as the question may appear
User address space - as I understand it, is in simple terms the space available in memory (physical and virtual) to run a process., in your case chkdsk.I must admit to not being fully conversant with it.
It appears to me - that as chkdsk in the way you commissioned it, runs at boot - before Windows itself loads - there is either a memory (physical ram ERROR) or if the ram itself is OK, a fault somewhere causing the apparent ram error -for instance the ram slot on the motherboard,
Alternatively it MAY be, that something is using ram, on boot before chkdsk can "grab it"
What I do know is that something is NOT right. By that I mean that the system in its entirety should handle this matter automatically and generally speaking, no user intervention is required. This presumes - that there is the basic requirements of :
1. Sufficient physical ram in the first place - clearly if it is GOOD - you have, as you have 4Gb I think you said, although if it is 32 bit windows, then Windows itself will only of course see 3.2Gb approx.
2. Sufficient free space on the HDD - clearly on the evidence available - this is not an issue - albeit this is not directly related to User address space - HOWEVER and only as an example a DEFRAG cannot run if the free space is NOT at least equal to the largest file on the drive.
3. See this articlehttp://blogs.technet...17/3155406.aspx
and scroll to the 5th image on the article.
4. On reflection the clean boot will NOT address this issue, as that process of minimising startup items and services - will NOT assist with the problem to hand.
RETURN THE computer to Normal startup. pleaseSteps to configure Windows to use a Normal startup state
After you used the clean boot to resolve your problem, you can follow these steps to configure Windows XP to start normally.
- Click Start, and then click Run.
- Type msconfig, and then click OK.
The System Configuration Utility dialog box is displayed.
- Click the General tab, click Normal Startup - load all device drivers and services, and then click OK.
- When you are prompted, click Restart to restart the computer.
5. I would check the RAM, using MEMTEST and running it for all 8 checks on at least the one full pass.http://www.geekstogo...sing-memtest86/
However - note the procedure - of a stick at a time.I am NOT sure if this has already been provided to you by my colleague phillpower2.
I would as phillpower2 advised RUN a FULL check on that hard drive, using the appropriate manufacturers check utility as that one, will provide you with the most comprehensive check and results.
