At startup of XP Pro SP2 I got the following message:

You can attempt to repair this file by starting windows set up using
original set up CD-ROM. Select r on the first screen to start repair."

If I shutdown and restart the computer it often starts but startup
takes a long time.

Before the slow startup or the failure-with-message there is a large
band across the bottom of the screen that looks kind of like barcode
and like a progress bar.

I recently tried to install SP3 and got an access denied error
followed by the running of an uninstall wizard.

What is happening and what is my best course of action?

Help will be appreciated,

- Any New Hardware/software installed recently?

You reminded me that yesterday I was having trouble with a program
message that running out of memory. I have 2G RAM. I increased the
virtual memory manually:
Initial size 2046 -->3069 MB
Final size 4092 --> 5116 MB
That did not solve the program's problem so I don't think the page
file size was wrong to begin with.

Another question before I undo that change.

I have 6 partitions: C: to H:. The paging file is on partition F: as
custom size. Partition F: has 9956 MB available and it is on the same
HDD as C:.

Partitions D:,E:,G:, and H: are set to "no paging file". But C: is set
to "System Managed Size" with no size shown. Does this mean that I
currently have two paging files?

Partition C: has room for 29,596 MB. I started to set C: to "no paging
file" but got a warning about possible trouble getting debugging
information if a stop error occurs -- so I left the setting as it was.

Could I be having a problem with the paging file(s)? Do I have a
problem with this setup? Should I the paging file setting on partition
F: back to the way it was, or to let the system manage the size?

- Have a look in the Device manager and see if there is /are malfunctioing
devices or Conflict in IRQs
- Did you scan for malware and visruese with an upd2date anti-viru and
anti-malware applications?
-How old is the machine?
- Open a run command and type in:
sfc /scannow click [OK]
Note you will need your XP CD Installation media handy if the SFC asked you!
