Have you followed one of the WinXP tweaking guides and turned off all the useless services that run at startup that you don't need?

? Windows XP Home and Professional Services 411
? WIndows XP Tweaking

Turn off the QOS Scheduler under network properties.

 

[thorin]

Ya and Disable "Automatic Updates"

Try going to www.passmark.com and downloading Burn-In-Test. Under the Configuration menu, goto Test Duty Cycle. Check all tests that apply to you (If you have no USB devices, uncheck USB, and so on). Set all tests to 100% load. Have it run overnight. Check if any errors occur with any devices while it is running. This will help you narrow down which device is causing problems, if it is a hardware problem.

I know its been said before BUT TURN OFF "QOS SCHEDULER"! It causes the exact problem you describe.

 

[locutus4]

I turned off Qos scheduler and even unistalled the damn thing.
I also d/l that Performance Test thing and i ran them all. My scores were all pretty good, from the little bar graph they give you, but the Disk -> Random Seek + RW was really low. What does this mean in laymans terms?

Well, buddy, turn on UDMA mode for your hard drives. XP has this little test upon the OS loader that turns it on and off. Unfortunately it turns alot of perfectly capable hard drives off by mistake. If it won't stay on then go into the registry and flip the "0" to a "1" then go into the hardware properties of the primary controller and flip it to "PIO mode only" then back to "UDMA mode if available". Viola, six times the hard drive performance and virtually no CPU use when using the hard drive.

Some litttle bugs makes XP suck for alot of people.

 

[locutus4]

ok that sounds like something i definetly need to do,
can you be a little more specific about how to turn it on in the registry. THANKS

 

[thorin]

"If it won't stay on then go into the registry and flip the "0" to a "1" "

Which key would that be exactly? It'd be bad if some newb read that and did a find and replace

LOL. The Primary IDE (SCSI PORT 0) key of course. For SCSI PORT 0 (0 = logical 1st instance/primary) go into regedit:

Find:

My Computer - HKEY_LOCAL_MACHINE - HARDWARE - DEVICEMAP - SCSI - SCSI PORT 0

DMAEnabled should read "1" and not "0".

1 = on
0 = off

 

[locutus4]

hey, i just did what oyu said
i was wondering if it mattered that my drive isn't a SCSI?

 

[locutus4]

ok i changed the value to 1 for both SCSI PORT 0 and SCSI PORT 1
I ran a program called DMA CHECK and it did say "DMA IN USE"
when i rebooted it was reset though, is there a way i can keep it on?

 

[MadRat]

It should have stuck. Did you go into MY COMPUTER - SYSTEM PROPERTIES - HARDWARE - DEVICE MANAGER - IDE ATA/ATAPI CONTROLLERS - PRIMARY IDE CHANNEL and under ADVANCED SETTINGS you will see where you can toggle PIO/DMA mode. Don't use DMA check, its an NT era program and is irrelevant in XP. You have to toggle the controller to force transfer mode to "PIO Only". Apply it then switch it back to "DMA if available". You should end up seeing the current transfer mode go to a form of DMA.

BEFORE you do any of that you have to force the registry back to a "1". That is the difference between forcing the mode to DMA and allowing it to set the mode automatically. Since you rebooted it will have gone back to its original setting. After these changes they should survive a reboot if you did it correctly.
