I downloaded the DPC Latency checker and I've been getting a lot of spikes. When I open my laptop and start the checker, it's all green; but as soon as I open Chrome or Firefox it starts to spike. It's spiking as I'm typing this. It's reached 65,795. I've disabled devices to try and find the cause but I can't figure it out.
View 2 RepliesWe are having ongoing problems with Windows 7 and mapped drive latency on our network. Our environment is as follows:Multiple servers running Windows 2008 & 2008 R2, some VMware servers (including our file server). Windows 7 x64 came preloaded on a brand new Lenovo think-pad, 4gb memory. This occurs on 4 different laptops. This problem ALSO occurs in exactly the same way on an HP Compaq x64 desktop running Windows 7 32. All systems are fully patched & up to date on SP's. Running IP 4 & 6 on all servers & Windows 7 machines Connected to GB Cisco switch.We run login scripts via GPOs that map drives (with net use commands) to 3 shares on our file-server, drives G, H and S.A fourth mapped drive to an IBM I-series does NOT experience these issues.
In Windows Explorer, mapped drives may or may not appear with red X's, but when clicked on they hang with a spinner and the green bar at the top of Explorer begins to run. This occurs randomly, but usually not right after boot up. It can take over a minute to complete. Also, in Word, which has references to these drives in file locations, file opening and saves can be very slow as it attempts to access these shares.This issue has delayed our roll out of Windows 7.Its unacceptably slow and cannot be used in a production environment.We have tried every suggestion we can find on the Internet:Turned off auto-tuning, indexing, thumbnails, set auto-disconnect to the max (both 99999 and ffffffff). Server & clients. No luck. Changed properties on the mapped drives to optimize for documents...no change.Changes setting on the network cards to disable flow control, set static link speed & duplex. Network drivers have been updated. Even tried using our wireless network and disabling wired connection...no change.All bios and hardware updates are completed...no change.Turned on and off network discovery..no change.
Disabled SMB2 on servers & clients...no change.Disabled firewalls, and unloaded antivirus (Trend)...no change.Safe boot with networking & clean boot with no services other than Microsoft...no change.
Testplatform HP Pavilion DV-5 Entertainment Notebook PC (4GB RAM, 2GHz dual-core) with MicrosoftĂ‚® WindowsĂ‚® 7 7048 x64 and Creative Sound Blaster X-Fi Surround 5.1.Driver:USB_W7DRVBETA_US_1_01_0091.exe. Tested with clean installed OS and only this driver.The Sound Blaster X-Fi Surround 5.1 is connected with optical TOSlink to a 5.1 Pioneer reciever. There occures great (and increasing) latency while playback of videofiles.-Sound will very noticably loose sync from video within a minute (all filetypes, not a codec problem). The latency will not occure with the internal notebook speakers, nor on same system with MicrosoftĂ‚® WindowsĂ‚® Vista x86. The Notebook ships with HPs "AMD USB Filter Driver" that should improve the performance of USB accessories, such as USB speakers or a USB TV tuner. I have tried to install this also on the testplatform to resolve the problem, however even though it seems to install fine the latency/syncproblem still resists.
View 2 Replies View RelatedHave been optimizing my windows 7 alot recently, i always do it when i reformat as it runs alot more efficient. Something i never did though was get my latency down. I had an issue were my latency was spiking to 1700, so i uninstalled my network driver and that brought my ping down alot, it spikes as high as 160 roughly. Is that fine for gaming or should i expect alot less? I have done the ping fix and other various tweaks to my nextwork and that seems to be the lowest i can get it.
View 4 Replies View RelatedI've been having DPC latency problems lately. It seems as if the latency ONLY spikes when using the internet. That's it. I play music in the Media Player; latency is fine, sound is fine. I play Halo and the sound is fine. I don't get it. Does the internet effect the latency? It only spikes when I'm watching a video or listening to music while online.
View 1 Replies View RelatedRecently I upgraded my computer hardware to a new motherboard, graphics card and processor. I moved my old hard disks (from my old hardware) into this new computer, turned it on and it started right up, I just had to re-validate Windows 7, which went without a hitch.Yesterday, I bought a new headset and started using it with my PC (before I was using desktop speakers), however, when I turned on some music, I was hearing a lot of stuttering/static while it was playing. I had this problem before, but it usually only happened when there was a program running that was taxing the CPU, and that isn't an issue now.I read around for a while last night about the issue, and it turns out that it's something called "DPC Latency", so I downloaded all the tools and tried to troubleshoot it for a few hours before I went to bed with no luck.So far I've tried:
-disabling HPET in bios & switching it to 64 bit mode (it was on 32 previously)
-turning off Powermizer on the Nvidia card
-disabling all USB ports one by one
-disabling all audio and network drivers
-changing the power settings for the CPU and HDD (tried this http://www.sevenforums.com/tutoria [...] -dipm.html
-updated all my drivers except by BIOS so far (I haven't tried that because it seems kind of risky, but I suppose I would do it as a last resort)
Another issue I was having was with my processor making this high pitched whistling noise, but when I turn off "disable processor idle" in the Windows power management area, it stops making noise. The weird thing to me is, it changes my dpclat.exe from full red bars to this for about 1-3 minutes (but after a few minutes it just goes back to full red bars, 28000ÎĽs):Before I went to bed last night, I turned on a 2 hour audio track and set it to loop with LatencyMon running. You can see in the screenshot below that the main culprits are:
-ndis.sys
-ataport.sys
-usbport.sys
-dxgkrnl.sys
-HDAudBus.sys
I've looked around on how to fix these individually, but I can't come up with anything at all. If I purchase a PCI sound card, would it fix these issues? I would prefer to fix it without having to do that, but if that's the only way to fix it for sure I can do it.
Recently the sound from my speakers has started to crackle when I am in a game and also when a UAC window pops up. I have used DPC Latency Checker and seen that when the audio crackles, the latency is very high. This screenshot shows the results of a UAC window popping up and being closed at the point when the bars are red.I was hoping it would resolve when I re-installed windows 7 and updated my drivers but the crackling still persists. By checking DPC latency when some devices were disabled in Device Manager one by one, I noticed that without my graphics card (nVidia GeForce GTS 250 512MB) driver installed, the audio crackling and latency was gone.

Can someone do a speedtest using the server in New York, NY?I've been getting an latency error everytime. Other servers work fine and the one in New York worked before. It's the one that's nearest my house, so that's what I generally use.
View 1 Replies View RelatedAfter about 24 hours of booting my computer, I have seen my DPC Latency spike tremendously. At first, I thought this was an issue with my network card (since disabling it would drop DPC Latency), so I bought a new card. The problem didn't go away, so I realized it was something else. High DPC Latency is a problem since it causes audio and video lag.
As I troubleshooted the issue, I have realized the spikes were caused from network activity. For example, when I am seeding [not necessarily uploading] many torrents or am loading a website, it shoots up.
Does anyone know what may cause this and how I could prevent it?
am running Windows 7 Home Premium. Aspire, Intel i5-2430M 2.4 GHZ, 64 bit Operating System. We only bought this at the end of December, 2011! When I am on Blogger, I haven't noticed it otherwise, when I move my mouse, sometimes the whole screen goes patchwork. There are squares of yellow, green and orange covering the screen, except for the address bar. (I attached a picture) I can navigate to a new address and it goes away. I am just a bit concerned there is a virus. I have run a full scan with Super Anti Spyware and I quite regularly use Crap Cleaner.
View 9 Replies View Relatedive been revieving some stutter noticibly when playing and form of video or audio and it has been getting worse as of late. Overall performance has dropped as well.Ive tried using Latency Checker and Latencymon and Realtek Ethernet Diagnostics Utility to try and diagnose the problem and the closest thing ive come to is that it has something to do with 'Realtek PCIe GBE Family Controller' as when I disable it the stutter appears to vanish and latency readings drop however I need that to connect to the internet so keeping it removed is not really an option.I have tried using a variety of drivers and methods from this forum and others and none have come to be of any use as of yet.

View 2 Replies View RelatedI received my copy of Windows 7 Home Premium. I skipped the Vista bandwagon, so I was moving directly from Windows XP Service Pack 3 (32-bit) to Windows 7 Home Premium. I opted to install the 64-bit version of Windows 7, as I had no issues when running the 64-bit beta.
As it turns out, I seem to have encountered an issue with my network adapter on Windows 7. Using any speed test site, such as speedtest.net, I get an extremely high ping (500ms +). I have tested another machine behind my router running Windows XP and there is no problem. Also, on the speed.io website, which tests connections per minute, I can only get around 200 on Windows 7, whereas I could get 2000+ on Windows XP with the same hardware.
Strangely, in games like Counter-Strike: Source, my ping is normal and in the 25-60 range on most nearby servers. Also, when running the ping command from the command prompt, most servers return a result lower than 100ms ... which is also normal. So, I don't understand why on speedtest.net, pingtest.net, and dslreport's flash speed test.. I get a ridiculous ping time of 500+ms. Web browsing does seem to be slow as well, as images take longer to load then they should.
I'm not sure whether this is a driver issue, or what. I have tried disabling both my firewall and AV software, so they are not at fault. I've tried 3 different version of the drivers for my NIC. One from the Gigabyte website, and two from Realtek's website (they released an updated version yesterday). My motherboard is a Gigabyte GA-EP45-UD3R (rev 1.1). I have all of my system specs listed on my profile if anyone needs to know more.
When my computer finishes starting up, it ends with what looks like blobs of colored pixels in a line at the top of my screen. This happened for the first time tonight and I have no clue what happened. I took out my video card and plugged my monitor into the mother boards vga slot. Same result. Then i used a HDMI cable from my monitor to my motherboards HDMI slot. Still, with the same result. I plugged my Xbox 360 up to monitor with the HDMI cable and it looks fine so it's not on the monitor's end.
When the computer is loading, the screen stays black. Then when my desktop would normally show is when the pixels show up and the rest of the screen is black.
I have an issue and think noone can solve it. This problem is randomly occured during commonly pc works such as web browsing, gaming, typing in notepad ,etc ; Freezing with Colored Vertical lines.Somtimes this ballon appears with such a message like "Display driver has stopped working and has been recovered".

View 1 Replies View RelatedRecently I've been encountering an issue where I'll be doing minimal tasks such as using safari with less than 4 tabs open. In the background I have photoshop open but not currently doing anything with. As well as aim and MSN and sometimes itunes. All of a sudden the whole thing slows to a crawl and I get the urge to throw it out the window. So i open the task manager and take a look and my CPU is at 100% (physical memory is around 30%). In the task manager i sort it so the highest CPU eating processes are at the top and they continue to jump around. for instance, safari might have 12 then 2 then 15 then 22 etc. I try ending a process that I'm not using and another process just spikes higher. if there is any drop, it's only down to about 92%ish. And it will behave like this until i close everything and start over. I've never really had this problem until recently and the computer isn't that old. I bought it in May 2010. It's a HP G62-144DX with a 2.13GHz Intel Core i3-330M Processor and 8GB of RAM. My windows experience rating is a 4.2 with my processor and memory being a 6.2. According to speedfan, my temps average in the 30s to 50s degrees celsius.

I have used startup repair and the computer is unable to automatically repair it, I have tried to reboot from an image of the computer and the same error happens at start-up. I have even gone as far as restoring the factory settings but there is nothing that will prevent that little streak from showing up and freezing my computer mid start up.
View 1 Replies View RelatedI've been using my PC fine for the last 3 years. A month or so ago I updated to Windows 7 Ultimate x64. That too has been running fine, then today, after about 3-4 hours of use, in the middle of a game, my PC screen suddenly got weird wavy lines and colours all over it and crashed. Long story short this has now happened about 10 times. Interestingly, I thought it was a graphics card problem, so I tried it on my HD TV (both TV and monitor connected via HDMI) and it did it on the TV too. I then uninstalled the nvidia (8800gt) drivers and restarted my PC. It works fine in safe mode, and in normal mode, but I can't change my resolution to 1680x1050, (it's native resolution) without installing the nvidia drivers.
I don't know if the problem is the drivers, (but never had an issue before?) or with resolution, (monitor problem?) Every time I do install the nvidia drivers the PC restarts normally, screen looks fine, and the PC seems to run, until I click on anything with the mouse and then the wavy lines and weird colours appear again and I can't CTL-ALT-DEL, I have to hard reset it every time. Once I left it for 5 mins. and moved the mouse a little every min. or so and that was OK, but as soon as I click on anything, it freezes and artifacts again. Also, my antivirus flashed red a few times and so did the windows clock in the bottom right corner of the screen, (very odd!) when the PC first starts windows.
That made me think it could be a virus, (even though I'm very careful about what I DL), but I had Avast run through a deep clean check and it found nothing. I also tried to get Win 7 to repair itself, which did nothing either! I've tried reinstalling the drivers, using newer and older nvidia drivers and I've tried to install my HG216 monitor driver, but since it's a few years old there is no official Win 7 support and all I have is an inf. file I can't install on Win 7. I haven't included a dump file, I know a fair amount about computers but I haven't worked out how to do that yet. Also, since I have to hard reboot everytime, in my event view the only errors listed seem to be about 'power failure', so I don't know if the bug or whatever would show up in the dump file?
OK, just woke computer up from "sleep," and everything is working fine. A few minutes later, all of a sudden, the monitor screen is filled with colored vertical and horizontal lines...and nothing is working nor is there anything else on the screen but the lines. Manually, shut down and rebooted. Opened with options on how to continue. I chose Normal Mode. Computer and screen now working as they should for the last hour.

It always stops in exactly the same place.
If I kill power, then boot again I get an offer for Windows to repair itself. If I let it, it cannot repair. If I select Boot Windows Normally, all is well.

View 3 Replies View RelatedI tried to do a routine (once a year) chkdsk via the command prompt Code: > chkdsk /r
> shutdown /r /f /t 1 . And upon the reboot, all I get is a black screen, no cursor, with ~4 rows of rainbow, garbled pixels at the very top of the monitor (certain pixels occasionally change colours). This occurs before the windows splash screen. I have left the computer as is, hoping it will eventually boot on its own with no luck. This was just a routine check. Some more information, I dual-boot with Ubuntu. I can mount and access the windows partition from Ubuntu, and I even ran ntfsfix in Ubuntu (which has some analogous functionality to chkdsk), but it didn't notice any problems.
I've noticed while playing Skyrim that my CPU spikes to 100% causing FPS to go down and the computer to lag.
I'm able to verify the CPU load via my G13 display set to the core temp application.
I've not noticed any type of consistency when this happens and by the time I am able to maneuver to the Task Manager to check which process is causing this, it stops.
I've had the HP DV6-3052nr for about a year and a half. My processor is an Intel Core i7, my graphics card is the ATI Mobility Radeon 5650, and it contains 6GB of RAM. A year ago at this time, I was running the game Crysis along with other programs all at once with an accumulated memory usage of 1,500,000. The CPU was at 15% while this was happening. Today, with all other programs closed, I can hardly run Skype, Oovoo, or Minecraft without my CPU spiking to 92% - 100%. The only way for me to solve the lag produced is by restarting my laptop. Why is it that the performance has declined, and aside from formatting, what alternatives do I have to return the performance to what it had once been?
