A "repair install" only works about 1/2 the time. Better to back up your data, zero wipe and reinstall.
I would suspect that you may have a bad hard drive. Get the Western Digital Lifeguard boot CD and test it from there. WD Support / Downloads / EIDE (PATA) / WD Caviar Blue
It doesn't matter what brand your hard drive is. The WD tools will work on any drive.
Let the XP Repair Install finish, even if it takes all night. It probably will still fail, but worth a shot. Chances are great your going to have to reinstall anyways.
If you still want help:
How slow is the PC getting into Windows to a point you can actually work?
Is it slow getting to the welcome screen?
Or slow between welcome screen and actually being able to work?
How much memory do you have?
How much free hard drive space do you have?
What sort of CPU do you have?
1. You can look in your event viewer
(Start -> Run -> type eventvwr.msc -> ok)
at the time of startup and see if there are any errors. You especially want to look in the System and Application Logs.
2. You can also try a clean boot to see what is causing the lag
Perform a clean startup to determine whether background programs are interfering with your game or program
3. You have also run the Hitachi hard drive diagnostics tool which just looks at the physical drive. Therefore run chkdsk which will look at the file system. To do this go to
Start -> Run -> type chkdsk c: /r -> click Ok . When asked if you want to force a dismount say No. When asked to schedule the check at the next startup say Yes. Restart your PC to allow chkdsk to run.
4. You can also run Autoruns. Save the file to disk, unzip it and run. Agree to the Eula and wait for it to gather information. Once it is done save the information to a file, zip the file and attach it to your next post.
5. You can also download and run this application: BSOD_XP_v1.3_jcgriff2_PROD.exe.
Once it has finished running zip the folder TSF_XP_Support which can be found in your Documents folder.
Attach the zipped file to your next post.
(Usually this program is used to gather info about Blue Screen Exception Errors however I am more interested in the event logs and the System Info it might provide)
You can run those in Safe Mode. You can also go to Start/Run and type SFC /scannow and press enter. Put your XP CD in the drive and it will replace any missing files from the disc.
