wow, the IRQs do look off. Your video card shouldn't be sharing an IRQ with your NIC! Especially IRQ5. IRQ5 is reletively lower priority. But anyhoo, the rest of it is okay except for that IRQ5.

Try to get the NIC to a different IRQ. Here is mine, just in contrast:

Oh and also, my video card uses IRQ 16, the NIC uses 20. But XP is supposed to dish that out properly.
 
Normally you can change resources from Device Manager. But since XP and Plug n Play, it doesn't let you have a resources tab any more. At least, it doesn't have a resources tab for my network card. Because it's all done with PnP.

BUT, you BIOS can have an entry for setting IRQs to specific PCI or devices. Check your BIOS and make sure ALL assignments are automatic. Or at least maybe see if the BIOS has your NIC at IRQ 5, and change it if for some reason it can't be auto.
Same for you video. But still, set it all to auto. And come to think of it, if you have a setting in the BIOS called "Plug and Play OS" or something similar, make sure it is YES.

If you do see a problem in the BIOS, and change it, if XP doesn't change automatically, then delete the NIC from Device Manager and let XP reload it again on restart, maybe it'll grab a different IRQ.

good luck
 
k will try, but atm i uninstalled it and am using Onboard LAN.. dont think if i uninstalled the nic card it should run fine?is there even a problem in my IRQs in the first place ya think? k thanks
 
I barely understood your post. lol

I'd say there IS a problem with IRQs if your NIC is sharing with video. That's just wrong. Both of those devices would require pretty heafty demands during online play in a game. And having them BOTH try to use the same IRQ while playing?! I think not!

Check System Info again and see if there are any conflicts like that with the onboard instead.
Remember to check BIOS.
 
Hmm barely understood my post.. well let me clarify hehe, sorry. I took out my NIC card, and switched back to using the Onboard LAN. I enabled it in BIOS, and everything ran the same ( with the lag etc ). Now I messed with the BIOS.. ( well looked around ) and saw the IRQs.. it says a list for example

IRQ device [PCI] 1 through all the way to 15 or so.. i reserved IRQ 5, and now it looks like this..

OK, so you reserved 5. So XP swaps you IRQs around. It's good that they aren't shared any more. But you didn't say if game is still bad after that? I assume so.

IRQ 3 for video is still a pretty low priority. But at this point I don't think that is the big issue.

Have you run any kind of hardware tests yet?

memtest86 for RAM
cpu stability test for CPU
Manufacturer's drive tools for your hard drive (look up at manu's respective web site)

After all you've done, I'm leaning towards hardware issues. Can we find another video card to swap?
 
HM swapped the Ati Radeon 9550 to a Geforce 4 MX 400. I uninstalled the ati drivers of course, and installed the Nvidia ones.. no luck.. i'm leaning more towards hardware problems too, i dont have any PCI slots used, only an AGP , and onboard sound atm, im guessing it would be the ram.. i found out its really slow, PC2100 (266mHZ).. gonna try to get a 3200 stick today if i can afford it.. money budget not so great atm.. =/
 
Very interresting. Surprised the video card didn't at least change things.

As for your RAM, you have PC2100 now, what can your mobo support? Remember that the FSB of your CPU matters as well.

For example, my motherboard supports FSB400, I bought RAM that was DDR400 also. But my CPU was 333fsb. So it clocked down my RAM until I bought another CPU that supported 400mhz and everything got in sync. You can buy faster RAM IF your mobo supports it, but it won't help a ton if your CPU fsb is slower and clocks it back down.
But if you suspect RAM I would first suggest testing it with memtest86, and then if it's good, loosen your RAM timings in BIOS.
 
alright i tried it, sorry i havent replied in a bit trying to do everything to this darn computer, don't see whats the problem still. i've yet to wait for my new ram to come in.. my CPU FSB is 800MHZ. and im pretty sure it supports DDR400MHZ. well i get back to ya . thanks
 
Question for Vigilante:

With my system (if you don't remember, it has problems similar to kryptoknight's), I've noticed that playing video files (.avi, .wmv, etc) causes a lot of lag to happen. It looks as if the audio and video are badly out of synch, but it's actually just my system lagging horribly with the video. This doesn't happen, however, when I play a DVD--they play perfectly. Any ideas? I was thinking about the video card (which the company that built my computer already replaced while it was still under warranty--this video problem wasn't happening back then), but DVD video is still processed by the GPU isn't it? Any ideas you can offer would be appreciated. Thanks.

You might read around www.dvdtalk.com. Here are two big questions answered:

Q: What's the difference between software and hardware decoders?
A:With a hardware decoder, the audio/video stream is decoded on a seperate add-on board in your PC. These add-on boards have one or more chips on them that are like mini-CPUs designed specifically for decoding DVD streams. A software decoder relies heavily on the PC's CPU to get the stream decoded into audio and video which the sound card and video card can deal with. There is a thing call Hardware Motion Compensation that is included on some video cards to lower the amount of CPU that is required.

Q: Does my video card offer hardware DVD decoding?
A:I have yet to see a video card that offers full DVD decoding. Some video cards have Hardware Motion Compensation which takes a little bit of the load away from the CPU for the video decoding. Many of the ATI cards have motion compensation as well as the nVidia GeForce.
--------------------------------------

As most home users don't have hardware decoder cards, your DVDs are handled mostly by the CPU. And IF you have the motion compensation thing, that helps a little.

But chances are good your codecs are somehow bad or corrupt for those other formats.
Download the program "VideoInspector" from http://www.kcsoftwares.com/index.php?download

It will give you interresting facts about the video files themselves and what they are and what codecs they use and whether you have them etc... It can list all the codecs you have in your system. Might be a good read.

Otherwise, you could try downloading a codec pack like the K-Lite Codec Pack. Browse around http://www.free-codecs.com/Codec_Packs.htm and see all the codec packs there. I almost always load the K-Lite pack, including being able to read Real Player files and Quicktime without having to install those apps. Very handy. Although I think the one including that is called the K-Lite Codec Mega pack. It's harder to find.

Good luck!
 
Chip driver update Just a suggestion

Just another suggestion. I just built my gaming computer on Saturday, MSI K8N Neo4 SLI platinum with AMD64 3500 and 1GB OCZ P3200 platinum DDR ram.

After Windows XP Pro installed itself onto the newly formatted WD Raptor 10K rpm SATA drive in ran like **** (insert your own descriptive).

Then I used the enclosed Live Update 3 software from MSI to update the on board LAN driver and nVidia nforce4 chip set drivers. The computer ran like a charm after that!!!! Remember this was just delivered in the box on Friday Aug 26 (then assembled by me) and I had to immediately update the chip set drivers!!

Aslo standard stuff: PS, make sure it has enough power, over heating of CPU??

Aslo standard stuff: PS, make sure it has enough power, over heating of CPU?? Try to turn down your desktop resolution. I took my old computer up staris for the kids to use (it's an ASUS a7A244 mobo with 512mB DDR Ram with AMD A4 CPU and GeForce 5200 video) not bad for some games. Any how on my monitor downstairs it ran fine and was set at 1024X768. Take it up stairs plug it into the 8 yr old monitor there and the mouse would hardly move across the screen! Nothing change just the monitor! Had to turn resolution way down to 800X600 so it would act like a computer again. Weird.

that would explain when I way overclocked my XP 3200+ and burned it out (it was easy to overclock- I got carried away) and downgraded to a XP 2500+ I couldn't overclock at all with the same PC3200 memory.
 
I just came across this thread after doing a couple searches in google, and I'm relieved to see that at least there is somebody else that is having the exact same problem I am. I still haven't been able to solve it, and I've tried just about everything. I'm using an Intel D865PERL motherboard with AC'97 onboard audio, I have 2 interior HD's and 1 exterior, a 2.4 ghz P4 processor, 1 gb DDR RAM, and an ATI Radeon 9800 All-in-Wonder.

This problem has been relatively recent (within the past month), but I cannot pinpoint any major changes that should've caused it. I've been pretty consistent with my computer usage behavior over the past couple months and I haven't installed any new hardware or significant software upgrades. All spyware and virus scans have been run to no avail. I've since updated all my drivers and scoured the internet for any and all options that could fix this.

At first I kind of just tolerated it, but it's getting quite obnoxious, and I desperately want to get rid of it.

If you have any luck fixing it please clue me in on how you pulled it off. Maybe comparing our situations together might reveal some kind of common factor that could pinpoint what the problem is.
 
Seeing as, like I mentioned, I found this thread from Google, your comment is pretty irrelevant.

I read through every post in the thread, and the problem was never solved. I don't see how bringing it back could cause any damage at all.

Every forum needs at least one post-nazi though, I suppose.
 
ringo380: what power is your PSU and how old is it? You've got a fair amount of equipment on this thing, you need about 450W high end PSU with at least 26A on the 12V supply and prob 50A on the 5V supply.

Check your CPU temperature as well. Both low power and CPU overheating are classic faults for laggy, unstable computer.

Cheers.
 
Think I found a solution

I had this exact same problem , and it seemed to just pop out of nowhere. You should check in device manager>>IDE ATA/ATAPI controllers>>Primary IDE Channel and then in Advanced settings and look for the "current transfer mode" (NOTE: most likely it is the primary and not the secondary causing the lag). If the current transfer mode is PIO only then you have the bug. PIO pretty much means that your harddisk data tranfer speed is at 16.6 MB/sec, not what UDMA can do (133mb/sec for instance). To read about the problem and solution go here!

fixed it in seconds!
 
Ok, ok, I know that this topic is friggin ancient, but I'll post my experiences here anyway just in case people with the same problem come across it in google. I've had this problem on my friend's laptop that I was fixing. It would freeze up every few seconds no matter what I was doing with it, whether it was moving the mouse or typing something. The most annoying part about typing is that whatever you typed while it was freezing up would not get inputted.

For me, it turned out that the issue was with a dead battery. Sure the laptop was running on A/C power, but when the dead battery was hooked up to the laptop, I would get these freezes. When I took it out and had the laptop only running on the A/C power, it was ok.

Yes, I know that the issue here isn't with a laptop, it's with a PC, but it just shows that the problem may be with the power supply. (This was mentioned earlier in this same thread, but my experience is one that confirms that it can be the issue.)
 
Help!

I have somewhat the same problem. My computer lags every 3 seconds or so when gaming. I am not sure, but I dont think it is the internet connection because I have another computer that plays the same games online without lag. Can anyone help me?
