Windows 7 Suddenly Very Slow With ~5%CPU Usage?
Dec 22, 2011
until a couple of weeks ago my PC was running perfectly, quickly, etc but one day i turn it on and suddenly EVERYTHING is slow.For example, every time i open a folder in explorer, i have to wait about 30secs for all its contents to load, chrome is being un-usably slow (same with other browsers) even just loading a google search. when i listen to music it often cuts out for several seconds and everything freezes up etcetc but throughout this my CPU will stay very close to 0% (like it should be) i have run virus checks, windows repair, a DDS check (whatever that is) etc and nothing seems out of place. on top of all this now windows is suddenly starting to question if i am using genuine windows 7 (i am) AND have got a few seemingly random BSODs?
SPECS:
->Windows 7 home premium 64bit (service pack 1)
->i5 750 intel CPU @ 2.67GHz
->NVIDIA GeForce 210 graphics card
->4GB RAM

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.

I use my laptop to dj with 4 nights a week so as you can imagine it is very important to me and a vital part of my income. a few weeks ago i had an issue where i had somehow picked up a virus and it forced me to do a complete format and reinstall of windows. however since then it has been running very hot and cpu usage has gone through the roof.
all drivers and bios are up-to date and the laptop is fully optimised for audio processing.
the specs are as follows:
hp g62 450sa
i3 2.27ghz
8gb ram
60gb ocz vertex ssd (with os on)
500gb 7200rpm hdd in drive bay (music only)
i have read that another complete reinstall may fix the problem, which i am prepared to do.. however onto the next problem, i left a cd walled in a club last week which had my recovery discs in it, when i went back the next week it was gone!!
how to get around or sort this, or is there anywhere that i can download a copy of the install discs. i have spoken with microsoft and they are willing to re-authorise my product key when i re-install.

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 have win 7 x64 on my laptop and it has been running fantastic for several weeks now. But all of the sudden it has just become unbareably slow and unmost completly unresponsive. I can hardly do anything on it it is so slow. It is not my laptop, which is still quite new and fairly fast. I have 32bit on my desktop which is much older and it runs fine. The only recent changes I have made is installing the latest updates for office 2007, and installing PS3media server with Java runtime. I can boot to safe mode and it runs fine and is not slow at all. I tried to restore to the restore point before installing office 2007 updates but it fails to complete. I was able to uninstall Java after taking almost an hour to open control panel and everything. Now i am trying to completly uninstall office to see if that fixes it, but I have a feeling it will take all day or more. This is the second time it has done this, both times I installed win 7 it ran really great for a few weeks than its just dead like it hit a brick wall.

All of a sudden on my Windows 7 ultimate 64bit, my Windows started to run so slow to the point where I can basically not even use it. All the stats show my RAM registering fine(4gb) and I just can't find what the problem will be. In its normal mode, it will take around 20min just to get to the front screen and is super slow when it comes to opening programs as well. It seems to run safe mode fine though, with speeds that I am used to.

The problem started 3 days ago when I was playing World of Warcraft and I was alt-tabing (nothing special, just ordinary stuff). After a load screen, where the game normally starts loading stuff, the alt-tabing was inresponsive and while I was in desktop, clicking WoW icon had no effect, like I wasn't clicking it. Soon I realized Firefox wasn't working as intended, so I pressed the reset button on my case. The pc gave me an error that, if i remember correctly, was that no boot device found. I played a little with plugging-unplugging my USB devices and the problem fixed after about 10 minutes. All good since yesterday afternoon.
So yesterday I got the exact same problem while I was playing an another game, but still at loading screen. The computer boots (from zero) very slow, even getting to "Starting Windows" screen takes a minute, and until I see the windows icon (the one about the SW text) 15 minutes pass. I left home and left the pc at that icon, and when I was back it was at login screen (weird because I only have 1 account without password so I don't ever get there). I pressed my account icon and after around 10 seconds (notice the time for just pressing a button) I got the "Welcome" screen, with the circle moving smoothly. I tried to use my Windows installation disc to find a boot problem, however it takes for ever to find a problem. Also tried booting in safe mode, but it takes a long time to load (haven't left it enough hours to load, I think it got stuck at some point).
My initial thought was of course a HDD failure. I have tried removing the ram sticks, unplugged everything but the DVI cable, played a little with the HDD sata cables, but nothing. The only thing I haven't tested is PSU.All the few operations I have managed to see (like the SW screen or the clicking) take a huge amount of time. I suspect it might not be a boot, or even HDD related, error but something else. The problem so far is the speed. The only thing I have seen to be working normally is navigating in the BIOS menu (which is graphical, I have an Asus motherboard). Also notice that just before I manually rebooted my PC, alt-tabing was inresponsive (not crashing, just very slow probably).
** EDIT ** : chkdsk reported no bad sectors
PC specs:
Windows 7 64-bit
Intel i5 2400
2x2GB Kingston 1333 MHz
Asus GTX 560 Ti

I just installed a completely fresh windows 7. I wiped and formatted the hard drive prior to installation. For some reason the install took like 7 hours. And afterwards, it still runs horrifically slow. I checked task manager and it shows my CPU usage at 100%. I checked applications and processes, and there are very few there, and all are between 2-8% CPU usage. I'm not very tech savy so I'm just going by the number shown under the CPU column in the Processes tab. Also it says there are 33-35 processes running, even though it only lists about 8 in the task manager. I've only installed 2 things since I installed windows 7, and those are google chrome and microsoft security essentials. Before someone says that either of those 2 could be the problem, they were installed afterwards, and it was slow and laggy before then. Windows has supposedly updated all the stuff it needed to because it restarted and updated a number of times, and I'm no longer getting update messages.I'm using an Intel(R) Core(TM)2 CPU E7500 @ 2.93GHz with 4 gigs of ram.

I have been using my HP Pavilion g6 laptop for around a year now, and so far it has been smooth sailing. However, around a day or two ago, my computer suddenly became unbearably slow on normal mode. I would try to open google chrome and it would freeze up my computer, and even opening the start menu took an incredible amount of time. This was a sudden onset of slowness and I cannot remember if I installed any updates that may have caused this. Using even safe mode, opening the uninstall part of control panel would take ages. I have tried many things to fix this:Used SFC/scannow, caused a crash.
Used disk check on safe mode, says that I need to defrag 1% of the disk. However, It also says there is a SMART check failure. I am quite confused about this because when I looked again it said that the smart status was "good". (HP support center) Deleted temporary files Checked task manager to see if there was any processes that were taking up too much memory, it looks good normally. However, on normal mode whenever I would open chrome the CPU would spike to 60%.
Specs are:
AMD A6-3400M APU with Radeon graphics.
6gigs of RAM

I have a HP I purchased at a store just over a year ago.I am running Windows 7 64bit. [code] I have some games (Spore, Sid Meier's Railroads) that worked great on this machine after I got it. The machine more then meets the specs. I could play for as long as I want and have no issues. Now I open either game and after about 5-10 minutes it is like the machine is overwhelmed with process. My CPU usage and ram goes up to 100% and everything is slow. When I click on a button to get a menu it takes 3-5 seconds for the menu to come up and then another 3-5 seconds for the mouse to move to the menu so I can select an option. So far I have made sure all my drivers are current, I have cleaned the registry with 2 different cleaners, I have removed all unnecessary programs from starting, I have tracked down process I determined to be non-essential and made sure those don't run, I have tweaked Windows to use less recourse (I should not need to do this now), I have removed unneeded programs, I have defragged, I have cleaned unneeded files, I have run Microsoft malware scanner (forget the name, no problems found), I have run Kaspersky 2011 in a deep scan and a critical area scan (nothing found), I even got one of those Speed Up My PC programs (I know garbage program) because I am so frustrated but that didn't do anything. I don't want to F disk it because I have too much data I need to keep.

For some reason my laptop has slowed down incredibly on start up. It is an HP Pavilion purchased last ovember and everything has been fine until 2 days ago. I started up and it took around 5 mins fo my desktop icons to show completely and then a further 2 mins before I could access any programs. I did a system recovery to before the problem started but no use. Any ideas before I take it back to the shop - its still under arranty.

I`m having serious problems with my windows 7 machine. It started yesterday when I was getting blank screens. TOday I turned on and its running very slow, freezing up and i noticed an svchost.exe process was using about 6gb of ram. I had to reboot about 5 times just to geta taskmanager up and then it would freeze up again. I tried a windows restore to about 4 days before incase it was some virus but it hasnt fixed the problem. Everything is ok in safe mode and i`ve tried running dr web virus checker aswell as installing norton antivirus and malwarebytes on an old windows xp installation on the same pc but theyre not finding anything.
Really dont fancy having to reinstall windows.

I can be away from the computer with no programs running besides the start up (which is just basic functions, kaspersky, and skype) and come back and the computer will respond like normal, except everything will jump around and take about 1/4th of a second for the mouse to move properly where I try to move it, if I am talking to anyone on skype their voices get chopped.

I have a fairly new laptop that suddenly, for two weeks ago went VERY slow. The start up time has increased from about 1 minute, to about 5-6 minutes. And it is generally slower, and freezing occasionally (The ones that freeze the most are programs like flash player (while browsing) and "explorer".) Although it gets faster after a while, it hasn't been as fast as when I got it. And not only that, for about 4 days ago when I was about to go to bed, I turned the "sleep mode" on. (It takes about an hour or so for it to run faster, and not freeze as much.) Anyways, it usually takes some time for the sleep mode to turn on, because of the laptop being as slow as it is. So I had fallen to sleep before the bsod had occurred

My problem is that my computer is very slow on startup and in general even though very little resources are being used. In the task manager the CPU usage rarely exceeds 10%. I have disabled all unessential startup programs and services and have defragged my HDD. There's a very little possibility of malware as i run Avast! which is fully updated.
Specs:
MS Windows 7 Home Premium 64-bit.
Intel Pentium T4500 @ 2.30GHz(49 �C Average)(>10%)
174GB free in HDD.
4.00 GB DDR2 (22% used on idle)

since yesterday the CPU usage on task manager doesn't go above 50% no matter what i run on my pc (benchmarks, movies, games) and I need more than 50% to watch movies so movies are playing slowly. I have no process stealing CPU time and I'm protected with Microsoft Security Essentials.

Suddenly opening programs took much longer than usual to load, I have a SSD and everything had been fast before. So today I just went ahead and reinstalled Windows and the speed returned for the most part. The problem I am having now is that if I launch an install program it takes 15-30 seconds to load, but if I right click and "run as admin" it launches instantaneously. I turned UAC off and I'm on an admin account.

So I have a Dell Inspirion 1545; One day when I turned it on, it started running extremely slow. It took almost 30 minutes just to boot to password screen, I put in the password and almost took another 30 minutes to get to desktop. Well then it started giving me errors like Dell Dock has failed and Windows (Something) had crashed, I got it up long enough to run Malware Bytes, and CCleaner to fix registry errors but nothing. Now I try to turn it on in normal mode and takes about an hour and thirty minutes to get through everything and to the desktop and thats if the icons decide to show. and if I try to get it into safe mode I get Bad_System_config_Info bsod.I dont really know whats going on, it decided that it was gonna shit out on a random day. The computer is out of warranty and Dell doesnt provide support for it anymore.Its basically un-bootable. There are no system restore points aswell, Repair your computer says it fixes everything but it doesnt.

I'm writing on my desktop laptop at the moment, as I can't stand how slow my laptop is..Well, I was on a holiday for a few weeks. And when I came home, my laptop suddenly went super slow!I have no idea how this could happen, as my laptop is fairly new, and the only thing I have installed to it is games from Steam. ( I got it in March I think?)It takes 10 minutes to start it, and when it's on, it is super slow. And not only that, it laggs allot! (Explorer stopped working etc.)I have disc fragmented several times, as well as used the disc cleanup utility.I have done a system restore, but that didn't work either, as it wasn't any old restore points to recover to.That's basically everything I've done, and it didn't work.
Something worth to mention,- The Internet browsing has become very slow on my laptop as well. (Not on my desktop.)The laptop is getting hot quite often, because there are only one fan in the whole laptop. And I haven't cleaned it a single time after I got it.
Spec:
Asus K53S
CPU - Intel Core i7 2.2 Ghz.

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.

My computer has become awfully slow after playing Assassin's Creed 2, I was playing then my audio went fuzzy and the fps went down to like 2-3 fps. It has been slow ever since, all my graphics card options reset so I fixed them then tried a registry cleaner.. It worked to some extent but my games are still laggy. my hard drive is clean and I have 4gb of RAM plus an i5, my GPU is a Nvidia GT 540m.

The computer was perfectly fine yesterday; normal speed and using the default Windows 7 aero theme (save the background obviously).Since today the computer is suddenly slow from the start-up already; When it comes to the "configuring windows" screen it takes about a minute instead of the second to get to the login screen. Then when I log in, everything is in the classic theme. A warning also pop-ups during start-up. Here's a screenshot where you see the task bar in classic theme while it should be aero theme. You also see there the warning on start-up. It basically says it can't connect with a Windows server, namelAfter start-up other problems are occurring.First of all, parts of the computer has become slow. The most notable is right-clicking on the desktop (and only the desktop!), it will take ages before the right-click menu is loaded.
Secondly, I can not change the theme, was my initial thought to do. All themes except the classic themes are greyed out and not selectableThirdly, the antivirus, Avira Antivir, starts up disabled, and whatever I try, I can not enable it. This started to happen after a few start-ups.So yeah, quite bothersome problems. I have tried the following solutions:- Scan my computer with Avira. I've scanned every single file my computer has, but my computer didn't find any viruses. This scan was done before Avira started acting weird.- System recovery. I first send it back to yesterday, which was right before an Windows update. The computer was fixed after the system recovery, but after a reboot every problem was back. Now for some reason none of the system recovery points are working, including the first one I tried.
So far I have one possible conclusion: It's the Windows update from yesterday. It installed only one update, which was a definition for Windows Defender, KB915597 definition 1.129.1102.0 to be precise. It's also the only difference between today and yesterday, and before and after the first system recovery. Sadly this update re-installs itself immediately after a system recovery, and I can't find anything about this update on google, so I can't say for sure this is the cause.
