After defragmenting C:drive, the following files could not be defragmented - can I safely delete/replace them?
Documents and Settings\Paul\Local Settings\Application Data\Microsoft\Windows\UsrClass.dat.LOG
4 1 KB \WINDOWS\system32\config\default.LOG
4 20 KB \WINDOWS\system32\config\software.LOG
3 124 KB \WINDOWS\system32\GCCollection.dll
28 1 KB \Documents and Settings\Paul\ntuser.dat.LOG
4 2 MB \WINDOWS\WindowsUpdate.log
9 2 MB \Documents and Settings\Paul\Local Settings\Application Data\Microsoft\Outlook\Outlook.pst
6 1 KB \WINDOWS\system32\config\system.LOG

Thanks
Paul
 
System files such as the paging file will not defrag due to being in use. There are different options to defrag the paging file and the drive if you have at least 256-512 meg of RAM memory. Simply turn off the paging file, press the SET button and restart your machine, THEN defrag. Allowing XP to handle the swap file size will frag again unless you set the same min-max numbers for your swap file settings. There is also a reg hack that deletes the swap file on shutdown and recreates it when restarting that helps stop so much fragging if you don't mind a slow shutdown. System restore and hibernation files can also be fragged. Simply turn off the hibernation option also before defragging, system restore, only if you don't mind losing your restore points and recreating them after your defrag
 
Tried all of the above but those files remain fragmented. I'm trying to avoid going through the recovery console to fix this problem. Are any of those files deletable? The registry has been affected which is why I'm thinking of the recovery console solution. There is a windows fix Q307545 but this may not recover everything back to its original state. Ran checkdisk also. My computer is sometimes hanging at the POST screen but boots up on the second attempt. Beginning to look like a reinstallation of XP!

Thanks Paul
 
This could be almost any thing. From the power supply being "weak" and not able to power up everything in the box, to disk drives, CD-Rom drives and fans overloading +12v. To defective memory modules or video adapter, and even the system board.
For example, cold motors in the disk drive and fans could be overloading the power supply and making other parts of the system fail. Disk drives as they age take more initial power to start up their motors. You could have added too many CD-Rom drives and fans for your power supply. Or the power supply could have aged and is starting to fail when cold.

All you can do is make sure all fans are clean and not binding. Then try unplugging things like the extra CD-Rom CD\RW drives and fans to see if it makes a difference. If they do and nothing else is wrong with them, its time to replace the power supply with a better one.

When you attempt second time HD may still be spinning slightly and wouldn't require as much power to get upto speed.
