Just Upgraded To Windows 7 - CPU Usage Stuck At 100 Percent
Dec 21, 2010
I have just recently upgraded my OS to Windows 7 Home Premium x64 from Vista Home Premium x64 using the Toshiba Windows 7 Laptop Upgrade. I've actually had the choice to upgrade ever since I got the disk around two months ago, but only now did I have enough time to spare to upgrade the system. Anyway, after upgrading to Windows 7, I noticed that my system was noticeably slower than usual. I could open several tabs on Chrome while running other programs on Vista and I would barely lag.
Now, I'm having problems only with a few programs running. I also noticed that my CPU usage was stuck at 100% and it's not going down or anything. My laptop isn't as slow as a rock right now, but something should be causing the processors to be at a constant 100%. My RAM usage is normal. 4 Gigs being used at around 50% right now. I'm just worried that maybe some programs that I had with Vista are slowing down the computer, but I was sure to uninstall or update any incompatible software too.
I'm running on a Core 2 Duo T6500 (2.1Ghz) Processor with 4.00 Gb of RAM. My laptop is around six months old right now.

I've reinstall my Windows 7. But now i don't know the reason why my CPU always show that 100% CPU, even when starting! I've found that in window task manager there are three processes: cmd.exe, cmd.exe*32 and again,cmd.exe, (I don't run them) and if I end them CPU usage will be normal.

I have 6GB of ram installed on windows 7 64-bit ultimate. For some reason I'm noticing that the usage will rise past 50%, but I am unable to find all of the used resources. From what I found, I'm using roughly 3.2GB of RAM when I add up all the memory usage under the processes tab.

My computer is running all the time over 50%. AMD 4x, W764, 2x hd 1 tb, ram 8 gb. MS Office, CS5, acrobat, pinnacle, etc. I have Avast and MS Defender. I have made twice online scanning with Fsecure and AVG. I have made weekly scanning with System Mechanic, CCleaner, Adware and Spybot. Nothing serious found ever.This problem came when I changed the system hd (C:) 40 Gb -> 1000 Gb and reinstalled W7. Now the Hd (C:) runs all the time, but what? I stopped all Adobe programs (Photoshop / Acrobat) and this decreased cpu usage to about 40-60%. When only 2 services was running (Avast and CatalystContrCentr) cpu runs still too much 10-30%. I made a repair W7 installation, but nothing better.

Some days ago I noticed after a couple of minutes I start mi PC, my CPU usage goes to a constant 100% , so I checked for viruses and such but MSE gave me nothing and neither Malwarebytes. Here's the weird thing, I checked the Task Manager to see witch process was causing this and it's always a different process (Sometimes MsMpEng.exe, sometimes dwm.exe and even taskmgr.exe itself) so I started killing processes like a maniac leaving just the few essential ones but nothing changed. I also stopped all the services with a delayed start, since the problem starts after a couple of minutes but the problem was still there. My system restore is disabled.

Computer has been running slow, so this is what I come across: the Memory is Pegged at almost 100% usage. I've got 4 gigs and this is what it looks like right after startup. I also went into Norton and checked it and apparently my Ram has been like this almost for a month. (I got an SSD and did a clean install and it appears to have run ok for a few days and then you can see its pegged out.

I am using win7. I get the msg backup your files. I start the process and get goes to 25% and sits there for a short while then it goes to 50% and stays there over 10 hrs. I get no other msg or requests for a cd or anything. I have done this for a dozen or so attempts to back up with same results each time.

It got stuck at 15%. So I rebooted into Safe Mode, tried System Restore. It failed, so I tried System Recovery Options, that failed too. Then I rebooted it regularly and it tells me that, in fact, System Restore worked. Now what do I do? (Besides backup my stuff.) Try to update Windows manually or do I need to do something before that?

When idle, my cpu usage is around 20%, which is allot more than it should be in my opinion. Whenever I start a game, Battlefield : Bad Company 2 which is the game I've been playing allot lately, my cpu usage doesnt come down from the 90's %. It just stays there and it often goes to 99% and stays there, once again. I've been running the game at a 20 fps average. When I could run games like far cry 2, cod mw , nfs shift and so on with settings on high with an average of 40 fps.

I have an HP G62 laptop and it has been running wonderfully for a year, it is a farely new computer. Then last week it was been running terrible slow due to the physical memory being almost 95% used. I have an i5 processor and 3GB of RAM and all i use this for is for school, I have all microsoft tools (word, powerpoint, etc.) and I don't game on this computer. I have been deleting unnecessary programs and defragmenting but it hasn't seemed to change anything. I have Norton 360 and i dont think I have a virus, or maybe i do??? My computer takes extremely long amounts of time to open internet explorer, itunes, or anything.

I have win 7 64 bit and have noticed that once my PC is active for more than a few days, the idle memory usage goes up dramatically. See pic, even with only idle processes, i am using 49% of 4gb ram. When i resart my PC, idle memory usage goes down to around 25%, which is a much more sane number. I've tried using a memory cleaning program called "CleanMem", but it doesn't seem to do anything.....

I have two hard drive in my computer, one I use for blu ray movies and storage. Lately, when I access the movies folder on the hard drive, the green loading bar will start loading and my memory usage goes up to 98%, why is this happening all of a sudden, it renders my computer useless for about a minute or two.

My netbook will bog down horribly. Rebooting clears things up - but only temporarily. This is a Toshiba NB505 Netbook running Windows 7 Starter 32-bit. Below are screen shots of task manager and msconfig.

I have a problem with OpenAL. If I start an application using OAL, the CPU-usage rises to 100% and the application crashes. Even the "OpenAL Audiodevice Enumeration" have got this problem.

I recently installed some new hardware into my computer.
Specs:
Gigabyte Z68XP-UD4
i5 2500k @ 4.5GHz
HyperX DDR3 1600
2x HD5870s
PC P&C 750W PSU
Crucial M4 64GB SSD (for my OS)
Everything went fine, computer performs top notch. But I'm having several issues (note, these issues happened BEFORE the CPU overclock also, so that isn't the problem).
1. Randomly (doesn't happen often), my computer will seem to lose internet connection. I'm hard wired right to my Linksys E3000, and it says that I'm connected, but no internet sites will load. Also, I cannot open the "network and sharing center". It just won't let me click on the icon in the task bar. And my CPU usage hovers around 25-30% when this happens. I downloaded and installed Process Explorer to see what the culprit was, and I noticed that of the 30% CPU usage, "System Idle Process" was taking up 75% of said CPU usage. It doesn't happen often at all, and restarting clears the problem up. But even though this SSD is lightning fast.
2. Smaller problem, but sometimes when I want to shutdown or restart, my computer just wont. It will sit at the "shutting down" screen forever and will basically do nothing, like there is a process in the background preventing it from doing its thing.

I have the same problem on my HP laptop, suddenly all system freezes and I cannot do anything except hold shut down button. I have monitored my CPU performance on startup and it goes crazy when my avast anti-virus is updating almost about 70% of cpu usage.
Technical details: Celeron Dual-Core CPU T3100 @ 1.90 GHz, 3gb ram, Mobile intel 4 Series Express Chipset Family
I haven't done anything with programs, have run ccleaner few times, also Disk Clean up and defragmenter. Scanned with the same avast scanner and Trend Micro House call, everything was fine. But never done any cleaning in 'fan' region.

I'm having problems with windows media player on windows 7. I've now had 4 fresh installs of 7 since its release (4 too many?) and every time i get the same wmp problem its either wmplayer.exe or the sharing service using 25%. I've disabled the media sharing service and disabled it in services window so it no longer runs, I only have one directory in wmp which is D:music on a separate drive from the OS no image or video libraries. Windows search indexer is also gone due to the total i/o causing a real slow system
All the download media info and other settings are disabled too, windows media player should just literally play my music and no more however this does not seem the case, it is also seems to be permanently trying to update my media library which it has done on all 4 installs too. Iremember having this problem too on XP MCE ? I am not sure if I have left any info out but basically I have tried everything I can so far and WMP will always uses 25% of my cpu even after its closed I usually have to kill the process manually.
System specs:
OS: Windows 7 SP1 64bit
CPU: Athlon II x4 640
RAM: 1x2GB DDR3 (667Mhz)
HD: 2x500GB SATA II 7200RPM
Audio: SoundBlaster X-FI
Video: Radeon HD 4670
music folder size : 69.2GB

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 purchased an Acer 5733. Why will my new higher zoom setting not remain as such, until I wish to reset. It seems erratic from one web page to another, and often automatically returns to 100%. Sometimes when I return to previous viewed web pages, the higher setting will have remained. If I set at 125% I want it to stay there!!

I just bought a Toshiba laptop that has Windows 7 Home Premium 64 bit installed on it. I have tried several times to install Office 2007 but for whatever reason it gets probably about 70 percent done and then it just hangs. At first I thought it was because the CPU sitting at 80-90 percent even before installing. I found some .NET services that were using up alot of that CPU so I disabled them and tried installing again but I still hung. I am getting no error messages so right now I am at a loss.

I have a Dell 1525, bought in Aug 2008, with 2GB RAM. I recently upgraded from Vista 32-bit to Win 7 32-bit. I am thinking about adding 2GB RAM, for total of 4GB and upgrading to Win 7 64-bit OS.
Can I just upgrade to the 64-bit version using the 64-bit disk that came with my Win 7 upgrade package?
Will it have to be a "clean install"?
Should I add the new RAM before or after changing to the 64-bit version of Win 7?
