WTF

How come my computer skips in videos and cursor movement? Every time this occurs, the next thing that happens is any music i'm currently playing slows down and skips ALOT when I launch Firefox.

The only remedy I've been using for this problem is re-installing windows. The problem comes back whenever it wants to. This time my video and cursor are skipping 4 days after I re-installed windows.

Anything interesting in your task manager?  Some program hogging too much CPU time?  Running out of RAM?

You probably keep infesting yourself with malware or shitware.  If you've got Norton or something replace it with AVG or Avast.

Also, Linux.

I really doubt that. That wouldn't explain why the problem arises at different times. There isn't anything I do different when re-installing windows and my web-surfing habits are the same afterwards. The only thing I can think of is me downloading more movies from uTorrent. Movies like Wedding Crashers and I,Robot, from some group or something called aXXo when getting the torrent at torrentspy.

1. Stop using Internet Explorer
2. Get rid of all the system tray bullshit; bullshit useless system tray crap is bullshit and useless
3. Check that your hard disks are in Ultra-DMA mode

Enjoy your AIDS.  Because you've got it.  And by AIDS I mean malware.  Your habits suck.  You can't be trusted with a computer.  Get a Mac, because you're obviously too retarded to be able to trust your own judgement.

I use firefox and I don't have any system tray bullshit.

How do I make my hard disks run in Ultra-DMA mode?

CMOS settings, though I'd suspect it's already on, or it'd take about an hour for Windows to start up....

+1 vote for AIDS.

With proper BIOS, disks, motherboard, OS, and cable. Since you probably have BIOS, disks and motherboard, you need to be sure you have the latest service pack for your OS, and an 80 wires IDE cable in good condition (good condition = perfect). You can see if you are running them in UDMA mode in sysdm.cpl (Windows+Run), hardware, device manager, IDE hard disks, properties of each, details or something, see that it says "ultra dma mode".

use WinPatrol, CCleaner, AVG or AVAST, bench your HDD, Use a system monitoring utility like Winbar to try find out when the system starts to lag which bit of hardware is causing it.

most of the time its not the hardware but some software clashing. check your system logs to determine whats happening

THEN USE GOOGLE!

It shows that my Primary IDE Channel is in PIO mode, while my Secondary IDE Channel is in Ultra DMA Mode 2.

I have Windows XP Proffesional and Service Pack 2.

So your primary IDE channel is in PIO mode. You need to get that fixed. Try replacing the IDE cable for the primary controller and devices by a brand-new 80 wires one.

GEH! PIO! No wonder! PIO is seriously old school. You've definately got something set up incorrectly there for it to fall back onto PIO mode. You need to check the jumper and BIOS settings for devices on your primary channel, and also that you have the correct chipset drivers for your MB installed.

if XP "at some point" notices a lot of CRC/timeout errors it sets the HDD back to PIO and greys out the DMA option, so there is no easy solution by just reselecting DMA

use RUN->regedit and go to the entry
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}

now there are three things that MAY fix this

1. add EnableUDMA33 (or 66 or 100 etc) as DWORD and set it to 1
in the entry 0000

2. delete 0001, 0002 etc (doesnt do no harm, win just has to recheck and redetect the values)

3. add ResetErrorCountersOnSuccess as DWORD in 0001 or 0002 etc (whatever is the HDD, or just add it in all HDD entries if you got multiple HDDs)
and set it to 1

if that doesnt help...dunno
bios update, driver updates may help too
here is the MS article which ...does not help much

I'm not a PC veteran per se, I kinda know my way around a computer, but I'll try my best to follow what looks like instructions in another language. Thanks for the help.

I'll let ya know if i blow up my computer or fix the problem.

By the way I'm gonna try >>14 first because I have absolutely no idea what >>12 and >>11 are talking about.

Err I meant >>13

I'm in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}

But I don't know how add anything.

>>16
rightclick-> NEW
after you created the DWORD ricghclick on it to change the value to 1 (1 on, 0 off)

dont forget to click the [+] symbol under the registry entry i gave you to expand the 0000, 0001, 0002 etc folders
0000= general settings for the drive controller of your motherboard
000x= drives/HDDs

>>17
i'm not the OP, but that actually worked for me.
had the exact same problem.

i'd never figured that out on my own that DMA wasn't enabled.
fuckin PIO has only 3.3MB/s

I added EnableUDMA33 to 0000 and deleted the folders/keys 0001 and 0002, then I remade the 0001 and 0002 keys and added ResetErrorCountersOnSuccess to them.

This is where I'm confused because it doesn't let me check what mode my Primary IDE Channel is running in. I go to Device Manager/IDE ATA/ATAPI controllers/Primary IDE Channel/Properties and the tab in which I check the mode is gone. It was called 'Advanced Settings' it's still there when I check my Secondary IDE's properties.

And none of the registry entries have the collapse symbol [+]

What did I do wrong?

What did I do wrong?

You didn't install Linux.

www.kernel.org

I checked that article >>13 posted and it fixed my problem.

To re-enable the typical, or faster, transfer mode for an affected device:
1.    Double-click Administrative Tools, and then click Computer Management.
2.    Click System Tools, and then click Device Manager.
3.    Expand the IDE ATA/ATAPI Controllers node.
4.    Double-click the controller for which you want to restore the typical DMA transfer mode.
5.    Click the Driver tab.
6.    Click Uninstall.
7.    When the process completes, restart your computer. When Windows restarts, the hard disk controller is re-enumerated and the transfer mode is reset to the default value for each device that is connected to the controller.

After I uninstalled the Primary IDE, it said I have to restart in order to do so. When I did the computer began to recognize the Primary IDE as new hardware, and after a few moments I said I had to restart again. I did and then checked it's properties and it said it's running in Ultra DMA Mode 5.

Thanks for the help. :)

you did nothing wrong, i do not have those entries too
and in the properties it also sais that there is no driver version  etc...

but on the other hand now the HDD works in DMA
check your transfer rates...
do you still get slowdowns?
I don't

I guess those entries reappear when you reinstall the drivers, but for HDDs the win standard ones are just fine

Okay, OP here.

The re-installing of the driver solution isn't working. It switches back to PIO in no time at all.

What's the difference between keys like EnableDMA33, EnableDMA66, EnableDMA100, etc? Maybe I should add something other than EnableDMA33.

WWW.LINUX.COM OR PEBCAK

Helped myself again. After checking the AT Attachment article on Wikipedia I came across this link: http://sniptools.com/tipstricks/getting-back-to-dma-mode-in-windows-xp#comment1891

Theres a much easier alternative than re-installing the driver:

To enable DMA mode using the Device Manager

1. Open Device Manager.

2. Double-click IDE ATA/ATAPI Controllers to display the list of controllers and channels.

3. Right-click the icon for the channel to which the device is connected, select Properties, and then click the Advanced Settings tab.

4. In the Current Transfer Mode drop-down box, select DMA if Available if the current setting is “PIO Only.”
If the drop-down box already shows “DMA if Available” but the current transfer mode is PIO, then the user must toggle the settings. That is:


• Change the selection from “DMA if available” to PIO only, and click OK.

• Then repeat the steps above to change the selection to DMA if Available.
