Flash, Video Playing, Sound And Generally High CPU Usage
Jul 1, 2009
i've done a fair amount of reading and searching on cpu usage in windows 7 (both beta & rc 1) and haven't had any luck with this issue yet.
the issue i'm having is my cpu usage spikes up to 80-100% very often and performance of any other task during this period is frustratingly laggy. these spikes happen from even the simplest action ranging from opening the start menu, to scrolling through text on a webpage and worst of all playing video (Internet is my benchmark tool, 80% usage guaranteed during video play).
using any web browser with 3+ tabs open is guaranteed to spike cpu usage over 50%. multitasking in general begets a sluggish os performance.
some of the solutions i've read and tried:
installing nvidia's windows 7 video drivers, no improvement.
disabling the hd audio in device manager seems to help a lot of people, i don't have this in my device manager.
sound drivers/devices also seem to be a leading source of cpu over-usage in a lot of cases. i've tried disabling/removing my sound card, drivers, and audio services to no avail. i initially had a sound card and on-board sound (ac97) running and disabling one of the two had a minor improvement in performance but nothing spectacular.
even with both disabled the cpu usage still spikes to 90-100% during video play, not to mention the video stutters and stops often.
i also had on-board lan in addition to a wireless card installed so i've switched between the two, disabling one or the other with no marked improvement.
setting the page file to manual control with a 4+ gb size setting, no difference.
disabling aero, using a windows 7 classic theme, no dice.
i like to think that my hardware is strong enough to handle video streaming/playing without maxing out the cpu but if you think i'm mistaken then feel free to let me know. my windows 7 performance score was somewhere around 3.4. i've also watched the process explorer extensively and i can't find any service that sticks out terribly.
any ideas? any diagnostic tools you guys would recommend?

This problem occurs on both of my desktop and laptop. The only similarity of these two is the OS so I am kinda sure this is a problem caused only in Windows 7 RC.When I was using Windows XP the system and game and sound run fine. However, after I switched the OS of both machines to Windows 7 RC, I realized that the sound pops very often and also drops game performance (Ex. WoW). This problem never occured in Win XP.I am pretty sure there is nothing to do with my sound card driver too because this problem doesn't only happen when I am using the onboard sound card but also Logitech USB Headset.Sound seems fine under normal usage, but it pops A LOT when I play games. The music and effects pop very often and drop the game performance a lot which causes the game almost unplayable. FPS drops when sound pops. So I am here assuming this problem occurs only when CPU usage remains high.

XMplay is like Winamp only the mem usage is astoudning for the interface and sound quality. Un4seen Developments - 2MIDI / BASS / MID2XM / MO3 / XM-EXE / XMPlay If you need a low usage music player with some nice prefs/options this is for you.

Recently the hiccups that happen when playing hich bitrate audio (happens in 320 kbps and not in 192) and videos (HD) started to really annoy me so I came here.I have windows 7, intel i7 870 processor, roland UA-4FX USB sound card, radeon hd5800 graphics card, and 4gb ram, I think all of them have up to date drivers.The clicking intensifies when doing rather CPU-heavy things like opening microsoft word but it is always there in high bitrate files, but the CPU load never goes above 20% in task manager.The hiccups are such that audio playback stops for a very short time periodically and making a click sound as if you removed the cable of the speaker.

I just installed windows 7 ultimate sp1 - Like the title says I'm seeing 35% cpu usage with nothing going on. I googled around and ran traces to see which driver it was, turned out the ahci driver was doing it. The USB driver showed similarly high latency but that can be delt with later. Most forums recommend upgrading your drivers but this problem has stayed constant both with microsoft's stock drivers for everything and after running windows built in search for drivers even after I manually grabbed the latest drivers for everything. url...BIOS is up to date4 GB RAM - Corsair something or otherEVGA Geforce 8800 GT450W psu1 DVD burner (sata)5 hard drives (sata) plugged into all but the first sata port because that caused nothing but headaches for me. Update - switching from AHCI to IDE in BIOS fixed the problem.

A few days ago my Flash and HTML5 audio stopped working, but the video shows up fine. I tried all of the browser I could think of (Chrome, Firefox, Opera, IE, I even made my own) and I got the same problem. Sound does work, though, in other programs like iTunes and Skype. When I tried Silverlight it worked fine.

I apologize in advance if my post is missing any information; I attempted to follow the directions for properly posting but while I'm am computer functional, I'm not overly computer literate. [code] The system constantly crashes when playing video games and games consistently lag. We have completely re-installed the OS and replaced all parts in the PC at least twice. When the system crashes the speakers buzz loudly, although sometimes it sounds like it's coming from the computer itself.We switched from Nvidia because everything has checked out and it was hoped that the problem was the hardware not playing nice to no avail. I'm still getting the same error/crash.

Whenever I am on my computer My RAM usage is really high. More than I think I could ever use up! When I am not on an App/ Browser my RAM Usage is still above 50-60%. I also think my internet connection has something to do with it because when ever I try to load a video/website it takes more than 10minutes to load a 30 second video!

I have a very high cpu usage for some reason. I wont even be at my computer and I can hear it working away.Take a look at the picture. I wasn't really even doing anything. I have itunes open, mozilla, skype but not doing anything.I've looked at the processes and it seems normal. Firefox is always top.

I don't know if I'm just overthinking/worrying too much about my laptop, but my CPU usage lately seems to idle between 10 and 30% even when I'm not doing much. I've noticed that TeaTimer.exe (Spybots real time protection) seems to hog some of this, and I'm not sure if I need it since I have Malwarebytes and SuperAntiSpyware installed. I've also noticed Firefox to be very laggy but this could well be a seperate issue. Also on startup my computer does seem to take up to five minutes to settle down after logging in.What can I do or what should I be checking?
Here's my system information:

I just reformatted my computer to windows 7.
And i'm kinda disappointed on its performance compared to some reviews i've seen in the web.
It seems that my computer consumes alot of RAM if i'm not mistaken.
Here are my processes and memory usage:
i have 4gb ram installed, but i installed win7 x32bit.
So when i on photoshop or other program that uses alot memory, the ram usage goes to 1.6-1.8 GB.
And during that time i felt some lag.

Lately, the cpu usage on my laptop goes very high without no reason. It sometimes bursts from 10 to 100 percent without any apparent reason. Looking into the task manager and sorting the procceses by cpu usage reveals that no single process uses very much cpu,instead about 10-15 percent is used by multiple services each.I run an Asus laptop k73s with an i5 2430m proccesor, an nvidia gt540m, 4 gigabytes of ram and windows 7 ultimate 64 bit. I tried everything from doing registry cleaning and repairing to disk formatting and virus and malware scans. Each attempt to no avail.

I have noticed when Iam downloading at full speed of 1.8MB/s on Wifi or LAN there is high DPC/IR (Deferred Procedure Calls and Interrupt Requests) CPU usage - and when transferring files in or out to USB hdd.. i sometimes get pops & clicks in audio too - the CPU is a Turion 1.8Ghz x2 with 1Mb L2 cache and 2Gb of ram, DPC/IR can only be seen using Resource Monitor in windows 7 (type 'resource monitor' into startsearch) or using Process Explorer software, I dont know much about DPC/IR but as far as Im aware it handles errors or something like that and I was told it should never even go beyond 1% cpu usage - its more noticeable on laptops as these have CPUs that arent as powerfull as desktops and have wifi, it seems to be worse with wifi. it causes latency problems in windows too and things like audio playback get pops & clicks and windows & apps become sluggish.
What brought it too my attention was the CPU fan on my laptop was on all the time and windows seemed to be sluggish when I was downloading even though uTorrent was just using 3-5% CPU, I noticed the total at bottom of Task Manager seemed to be more than what would tally up in the window, it was when i used resource monitor that I seen it.
WiFi @ 1.8MB/s = 10-15% DPC/IR cpu usage
LAN @ 1.8MB/s = 5% DPC/IR cpu usage
Copying Files to USB HDD = 15% DPC/IR cpu usage (this test was odd as it was some time ago i done this one, but I remember it was either IN or OUT that had the increase, probably IN (and OUT was <1%) , I tried SDcard too and got varying results)ive even seen it max at 40% when downloading on wifi and copying a file in/out too usb hard-drive at the same time...

I was using vista x86 up untill windows 7 came out, it was the I decided to go for my first x64 operating system. I have an i7 and 3gb ram.
Ever since I've moved over, games take up a stupid amount of memory, they'll go to 80 - 90%. I recently decided to install Crysis Warhead as I never got round to completing it, last time I played it I was on vista x86 and it ran fine. However now, it takes forever to load and/or freezes because there's no memory left.
I've tried setting the page file at 200 - 1024, 1024 - 1024 and turning it off, none of that makes a difference. I tried increasing it to 4096-4096 just out of curiosity, that managed to load the game, however, while I did have a constant 50-60fps I was lagging really badly and had 91% ram usage.
Am I missing something here, does anyone else have this issue?

I have a Lenovo laptop with Win 7 Pro.
When I leave the laptop on standby, and come back to it after 10 minutes, the fans are blowing loudly. I have a CPU gadget which monitors CPU usage, and I see that right when I resume from standby (move the mouse), CPU usage drops to normal.
At first I thought Security Essentials is doing some scanning or windows is indexing some files, but this happens every time the computer is idle for longer than 10 minutes. I have a suspicion that my laptop could be part of a bot network.

system: inspiron 1420 windows 7 issue: suddenly slow system (cpu usage usually raises to 100% when opening any programs such as a web browser, then dips back down when everything is loaded enough) attempted solutions: anti-virus, malware, anti-spyware programs | chkdsk, sfc /scannow |memory diagnostics | adjusting appearance | using task manager to locate highest cpu usage program (none of these attempts have identified the problem.)my system which is a dell inspiron 1420 windows 7 was recently given a clean install to windows 7 from vista. everything was going fine for about two weeks when suddenly everything started to become sluggish.now when i for instance open a video on Internet, the video will buffer, and while that's happening the audio that plays sounds like a droning machine as if it was being disconnected from the matrix, ha. after the video loads enough, the sounds remains normal. not only that, but the mouse will stop, stutter, freeze, then continue after the video has loaded enough to where the mouse can move again. i'm also experiencing freezes on this machine, and usually when the computer does freeze the mouse pointer disappears.
i have already tried many things, such as running anti-virus, malware, and anti-spyware programs which had all come up with no threats. i've run chkdsk, sfc /scannow (which did in fact find corrupt files, but they were unable to be repaired. if anyone can tell me how to repair those files that cannot be repaired, i would appreciate it), and i've also done memory diagnostics, all of which are not identifying with the problem i'm having.

I have a Sony with win 7 64-bit and 4 gigs of ram. About a month ago I started to notice my computer running slower. When I checked windows task manager (performance) it was using 3.5 gigs of my memory. I restarted the computer and it went down to 1.5. I have on occasion had to restart twice to get the memory down. I have run virus checks and reg cleaner but it still occurs.
