CPU Usage Spikes (100%) And Windows 7 Lags?
Aug 4, 2011
I have a Dell inspiron e1505. 2 gb RAM.
Essentially I am getting seemingly random spikes in my cpu usage where it ramps up to 100% and windows basically freezes for an extended period of time. Sometimes I simply have 1 google chrome tab open with no other apps actively running in the foreground and I get these cpu spikes. I just did a clean install of windows 7 to try and eradicate this and it persists. I am at a loss as to what the problem is. What is odd is even though the cpu usage spikes at 100% my available memory is almost always nearly around 50% still. So I am just not sure what is happening.
(unfortunately to no avail) High CPU usage, programs crashing, windows hanging - Tech Support Forum
Anyway like I said I eventually just did a clean install but the problem persists. Since the clean install I have not noticed and flash problems with chrome (as per the tech support forum thread) just random cpu spikes.

On occasion my physical memory usage will quickly rise form between 1 to 2 gigs of memory usage to over four until it reaches 98-99% percent of memory usage. I am running on 5 gigs of ram. This problem has even occurred while the computer was essentially idle. When this happens the computer loses almost all functionality. I've tried ending all non-essential processes to alleviate this problem but it makes no difference.

I have a problem where my CPU spikes to 100% while playing online games. When I check task manager there is no process that actually seems to spike. I have also tried a fresh windows install but this didn't fix the problem either. This only occurs while playing online games (starcraft II, league of legends), I tried offline games to see whether or not it had anything to do with the internet and I didn't get any cpu spikes at all playing offline games even though these games have higher performance requirements.

Now to the actual problem. The reason I bought all this RAM was so that the computer would run faster and more smoothly. Despite the large amount of memory, however, I still experience frequent spikes in CPU Usage, which I have learned is not related to RAM very much if at all. Regardless, I would still assume that my system wouldn't have to overexert itself to run simple tasks like Windows Explorer (i.e., folders, desktop and taskbar) or the Task Manager itself.
Either of these tasks, as well as others such as "System," "svchost," or "File I/O Surrogate" (none of which I know much about) can spike to anywhere from 30-70% of the CPU without warning, and when it does, the total CPU Usage ends up being 100, which REALLY makes my laptop sluggish and unresponsive.
I understand that RAM does not directly impact CPU Usage, but I would also assume that, since my laptop isn't ancient, that its CPU shouldn't struggle to display my folders/desktop/taskbar, or to run the Task Manager itself. I also run a daily virus check with Symantec Anti-Virus, so I don't think infection is the issue. In addition to that, I monitor memory usage alongside CPU usage, and the memory usage never goes higher than 10.5 (it usually hovers around 6-8) or so GB of my available 16-- insufficient RAM is also probably not the problem.

I just installed Windows 7 64 bit and FL Studio 10. Whenever I open up a project in FL studio 10 the CPU spikes to 90%. I am usin an ASIO soundcard in the EMU 1616m and a quadcore CPU. This never happened when I was running FL studio inside XP 32 bit.

Ever since I installed Windows 7 on my PC a few months ago I've been getting consistent ping spikes on basically every game I play, but mostly on this one I'm playing most of the time. My ping will be a solid 20-22 for few minutes (often less and more often) when all of a sudden my ping spikes in the hundreds (150-400). Along with this, sometimes my UDP goes red. This never happened with XP, I'll even have the same game server on beside me with XP and I'll never see ping spikes. I've talked to other people who play the game and they experience the same thing, many of them for this very reason have decided to stick with XP for these particular game(s).Another thing that I've noticed since installing 7 is a delay (no better way to describe it, can't say it's lag since it says my ping is 20?). While on my XP PC 20 ping will feel just like that, 20 ping. On the 7, it feels like 50-70 (while saying 20). The game I play is very dependent on fast reaction times so this is obviously very annoying to me.

've encountered in the last few days on my laptop. I may be wrong but I'm pretty sure it has happened since a Windows Update installed as I remember a big registry update....like I say, may be wrong! [code] My physical memory is pretty stable at around 1.6 to 1.7 Gb but my CPU spikes are just haywire and latency on keyboard strokes is driving me nuts! Even running no programmes the CPU is betwen 26 and 100%...whilst I'm running IE then it's 95 to 100%.The task manager graph is just a total zigzag.Unfortunately, i don't think I have a restore point to go back to pre-Update so I don't think I have that easy route out.

The worst thing is, this is a new PC and I've just freshly installed Windows 7 Home Premium 64-bit on it.
I've already updated ALL my device drivers to the latest available, as well as applied all available Windows updates, yet it still happens. These weird CPU Spikes can occur seemingly randomly, and thereafter causes my OS to inevitably freeze or become EXTREMELY unresponsive at best. I am unable to Restart the computer (it either hangs at logging off or doesn't seem to be able to shutdown (left it trying to shutdown for 1 hour).
The onset has happened to me so far in these scenarios:
1) Just surfing the internet
2) Playing a video file
3) Leaving the computer idle (It was frozen when I got back to my PC)
4) Changing control panel settings
I was lucky enough to capture and save the screenshots showing it in Task Manager. The culprit process seems to be the 'SYSTEM' process (which shows only 25% CPU usage, however as you can see my ACTUAL CPU usage spikes all the way to 100%!
Quoted below is my system information:

Lately I've noticed that my laptop starts acting choppy at times. It lags or chops whenever I watch a video, play a game, sometimes when I'm doing nothing. I have windows 7.

I've been having some frustrating issues with Windows Explorer (on Windows 7), and I've pinpointed the cause to one stubborn wmv file on my external hard drive.Whenever Explorer accesses the location of this wmv file (unfortunately the root directory), the green bar at the top starts slowly running, presumably trying to load the thumbnail of that wmv file. This wreaks havoc everywhere, as any other folders I navigate to then have missing thumbnails that will not load... and when I go to "Computer", it's completely empty and the green bar atop runs indefinitely, but never makes any progress... only heating my computer frustratingly.Furthermore, when I restart explorer, the error "the remove procedure call failed" shows. Logging off or pressing Ctrl+N in explorer have provided temporary solutions so far.

I'm using Windows 7 Ultimate with a 6-core AMD processor, 16GB RAM, SSD as primary. Whenever I transfer a large file over the network to another system the mouse and other applications will persistently hang for a second here and there as long as the transfer is in progress. I'm sending 8-10GB files over from the secondary 2TB 5400RPM drive and no resources are showing as maxed out so I don't get it. I'm thinking of trying a 3rd party file transfer solution again, but this still shouldn't be happening with the default.

Recently 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'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?

This problem has been plaguing me for so long. Sometimes when I install games or extract games that is in a RAR file, my RAM spike to a point where 94% of the memory is used. The longer the installation of the game or file is, more ram is consumed. Anyone care to enlighten me how did this happen? So far the only way for me to solve it is to reset the whole system since I can't do anything on the task manager.
My PC Specs is quite updated so I doubt it is some hardware problem?
Intel Core i5 750 @ 2.66Ghz
4GB Kingston DDR3 1333 Ram

Something is wrong with my Sony Vaio FW series laptop.. I get major FPS spikes in any game I attempt to run (Dragon Nest, Audition), with FPS dipping down to ~10 every five seconds. When I check Task Manager, it's the games that are taking up the most CPU with overall CPU usage at 90%+. This is really strange and abnormal as I had never had any problems with those games taking up CPU and fps spiking until today (they ran fine yesterday).Between yesterday and today.. I used compressed air to clean my laptop's fan, and I visited some movie watching sites (which resulted in some popups appearing). I'm unsure if the problem can be attributed to a virus, but I ran a full scan of Malwarebytes and did a deep clean on Advanced System Care, none of which helped fix the problem. Firefox, Skype, and other applications appear to run as quickly and smoothly as they did before. However, I've gotten three BSODs in the last 30 minutes, and my laptop appears to be overheating: Here is my Hijack This Log : xks.
EDIT: I understand that a system restore will likely solve all problems, but I want to save that as a last resort.
EDIT1: I think the BSODs were a result of me running CPUID HWMonitor to check for the temperatures - each BSOD occurred right after or soon after I ran it. I'm unsure why running that specific program triggers a BSOD, but if I leave it alone my computer appears to be fine (no BSODs so far after I stopped running it).

I got a new laptop (DELL XPS 172nd Generation Intel Core i5-2450M processor) recently and I had it returned for having lag spikes that would happen whenever it felt like. (gaming, videos, Reddit, etc.). Dell sent me a new computer that also has the same problem, lag spikes that give off a noise that you would expect from a transformer.

i am trying to record some game play for a Internet channel and i keep getting lag spikes on 1 game. when ever i play league of legends i always will have a frame rate drop. i usually get around 120-90 fps without recording and 60-40 fps with recording but for some reason there will always be a drop to around 1-10 for about 2 secs.

I've been having trouble with my PC for quite a while now, and have been looking for a fix for a long time. When I'm using my computer every so often I will get random lag spikes, that last for around 2-5 seconds. When it happens everything slows down, and the sound sounds like a broken CD/DVD where it goes all choppy.Recently I was staying at a friends house, where my computer wasn't connected to the internet, and while I was there I didn't have the problem at all, so I think it's something to do with being connected to the internet.

I installed windows 7 RC a few days ago, and every 2-10 seconds it would spike with lag, the mouse would jump and the internet would do the same i would get a consistent low rate and every now and then it would jump to normal.
I found out the problem was with my network card, i had to roll back the driver on my network card for it to work properly.
Now my network card updates itself every now and then and i have to go back and change it again.
I was wondering if anybody else has had similar problems like this, and or found a permanent fix for this.

I'm having incredible frustration with my pc. It LAGS during most games, including the following,
[code]...
So why on earth would these games lag??? IT's DRIVING ME INSANE! I can't play them without a lag and my system specs are above the "REQUIRED" system requirements to run the games.
1. There are no additional process's running in my process's that are chewing up my memory and slowing my pc down.
2. PhYsix is set to auto so it selects the best CPU for physix controlled games. And I've also tried both.
3. My games are run in the LOWEST possible game and graphic specs to try make it
less laggy, to no avail.
4. 3d is "disabled". So it can't be slow.
5. I do not have any virus's, and all my display drivers are correctly installed and up to date.

Okay so a couple of problems. When I don't use my computer, the harddisk light is on. Not blinking, just flashing with no pause. I'm having some lag spikes when I boot and it says "Welcome", I checked my Event Viewer and it said: (DeviceHarddiskVolume1WindowsSystem32msiexec.exe) .. some registry error was generated. It seems like msiexec is some sort of bootup tool having contact with my HarddiskVolume1?

If I left my computer for 30mins, when I came back, it lags. While lagging, I opened Task Manager. The RAM usage its only 2.8Gb out of 8GB. If I use it for 2 mins, it back to normal...what is that?

I have had my laptop for around a year now, and it's always been pretty fast for a cheapish laptop, It's an advent modena m100 in blue, but recently it has started getting real slow, like my CPU Usage is at 100% all the time and my Physical memory usage is running quite high aswell, without even having any programs open.

When I first boot up the machine and start using it (win 7 ultimate 64bit) the memory usage stays arround 40%. If I keep using it, the memory usage will slowly increase until it reaches 99%. If I boot up the machine and just leave it there for a couple of hours, the same happens.I try to restart (via windows), it logs off, shuts down the system, the coolers keep spinning, the motherboard lights are still on, but it doesn't boot up again. It remains like that. I have to restart via reset button or power button.

Recently when ever I'm playing games or running programs, they suddenly spike up to 100% cpu usage and start lagging very badly.They normally run fine and quite smoothly but then after a while, they suddenly stop working. It usually stops if i leave them alone for some time or if i close the program, but i don't think the application itself has anything to do with it.This happens on many different games and applications alike, but normally only with games, even old ones.I checked my processes and it says i have 61-65 processes running! Isn't this too high? how can i check if those processes are OK? I have HijackThis and can post a log file if needed.

I recently bought a new computer and everything works fine, I play League of Legends, Borderlands, Left 4 Dead all in high settings and I get constant fps and very smooth gameplay.But when I try to play the oldest game ever (Counter-Strike 1.6) I get fps spikes very very often. I am playing in OpenGL, yes. I disabled vsync, yes. I even went to my nvidia control panel and just straight up set everything up for high performance and not quality and I still get fps drops to around 40's-50's.
My computer specs:
-Intel i5 3.3 Ghz (Turbo Boost 3.7) L3 Cache 6MB, Quad-Core, 32nm
-2x Kingston 4GB DDR3 (1333MHz - PC3-10600)
-Seagate 1.5TB HD 32Mb Cache, 7200RPM
-ECS NVIDIA GeForce Black GTX 560 Over Clock, 1024MB GDDR5

I have noticed that svchost.exe is doing this connections every 10-20 seconds, and every 10-20 seconds there is a lag spike that jump the latency up to 1000ms and more.
I want to disabled this periodical connections that windows does...I don't know what Has caused this...I have tried completely disabling svchost.exe access to internet but than no application launched can connect to internet.
The connections are port specific, the remote ip to which it connects to is always 192.168.1.1:53, which for sure is the ip of the dns (redirected by the router) plus the port 53. I have tried completely disabling the access to this remote port for all the local ip and local ports with my firewall, but it just keeps avoiding it. I have used this method with the connections to microsoft with the port 3544 witch are being disabled.
