Constant High CPU Usage
Apr 6, 2008
I have a Intel Core Duo 1.60 ghz processor with 2gb of RAM and my computer will constantly have 100% of the RAM taken up. I usually only run firefox, AIM, and itunes at a given time and I don't understand why my computer can't handle it. I will open up the task manager and it doesn't seem like any one task is taking up that much RAM, I don't understand what is doing it. I ran a virus scan with norton and it says I am clean, so I am puzzled by how my RAM could always be maxing out.

I think I have tried everything and I am not computer savoy enough to try some. But recently my computers CPU has been fluctuating a lot and has been pretty slow..I took off most of the start up programs and only have a few (virus software etc) but I was wondering if maybe it could be not by updating my drivers.. or bc i only updated some of my drivers.
I am currently running
4 gigs ram...
ATI Radeon HD 3200
vista 64 bit
professor amd duel core..

Why is my CPU Usage so high? It's using 100% sometimes and sometimes 88%. From 88-100% CPU Usage. What is the problem here? Is it supposed to be that high?

I have a Very Powerfull Processor, an E8400 3.6 GHZ and after i installed updates when i move my mouse on my desktop my explorer.exe process SHOOTS UP to 11 percent CPU usage its very unnecessary, on xp it stayed at 0 percent, Anyone know how to fix this? Whenever i move my mouse on my desktop explorer.exe uses anywhere from 5-11 percent CPU.
Its strange because if i move my mouse over firefox the firefox.exe cpu usage goes high to. same thing with ie7. Basically anything i move my mouse over gets 11-15 percent CPU usage, its very unnecessary.

My computer (Dell XPS 1330) runs fine without the monitor (Dell 20" SP2008WFP) but intermittently hits 100% CPU usage with the monitor plugged in - usually if I am running more than 3 or 4 standard office programmes - and then returns to running normally if the monitor is unplugged. I have 4GB of RAM and 2 x 2.5 GHz processors, so don't think this should be a problem. The laptop and monitor seemed to work fine together for a few months but subsequently the problem got progressively worse over a few months.
I have tried stopping all processes in TM when the problem occurs - none stand out as being the culprit. The only common occurrence is that the task manager process itself runs at 20%+ to 40% CPU usage when the problem occurs. I have already tried defragging, spyware, cutting out all visual effects and all sorts of other performance improvement options - I even totally reformatted the hard disk before I realised that the problem was related to the monitor being plugged in! I have tried rolling back and then re-updating the drivers for the monitor and the display adapters, but the problem persisted.

Both pre and post SP1 whenever I install a game my memory usage starts to climb. It usually hovers around 30-33% at idle. While installing it eventually peaks @ 99-100% and will drop to about 95-97% after the install is finished. For the life of me I can't figure out whats causing it.
I just installed lost planet and had the same issue. It happened with COD4, Supreme commander, and Crysis too. I've added screnshots from during the install, post install and after I reboot (because the memory does not go back to normal until then).

My problem is when ever i try to launch certain applications it causes an extreme slow down of the system and high cpu usage, after 30+ seconds the system goes back to normal and the program responds fine. Seems to be a bit slow in loading as well. Programs affected include winamp (latest), nero 8, windows media player 11, powerdvd, right clicking on hard drives and opening properties but not accessing the hdd's. Programs which aren't affected include media player classic, open office, ie7, firefox 3, vlc player. I have been messing around with my codecs recently trying to get thumbnail previews of the .avi files on my pc which suceeding in by installing ffdshowx64 so i uninstalled this and the 64bit vista codec pack to no avail. I disabled kaspersky but that was no good either. I also disabled my raid array but that had no effect

since a few days my cpu has always cpu load of about 90 % at core 2. Vista is very slow. Taskmanager shows no applications with cpu usage. Now i installed process explorer and i can see that 45% cpu usage (this is 90% of core 2) is for "System / hardware interrupts". Which interrupts are the problem, what can i do to fix this?

It seems BlueScreen has been a problem for many Vista users. I was reading the forums trying to find an answer, and it seems the best thing I can do is show you the last minidump.

My memory usage (shown in task manager) is at a constant 80 to 90 used even though I have nothing running.(cpu usage minimal) What is causing the problem or what is using this much memory?

No infections of any kind can be found on this PC, yet MSMail, MozillaFF and IE7 lock up constantly. How can this be fixed short of a reformat and reinstall of the OS? Vista has been as unstable as W98 for us. Is there any way to get it as stable as XP? Does anyone know what causes these constant W98 type freezes so many of us are enduring with Vista?

The notebook I buy is installed with Vista Home Preimum. After using it for a while, I found the LED of hard disk is lighting continuously. I spent some time to search the related topics on the internet. And, then I tried to
1). Disable SuperFetch Service.
2). Disable Windows Indexing Service.
3). Modify the memory management for DisablePagingExecutive = 0
I feel that the interval of HDD LED lighting becomes to low. However, it is not turned off when I don't use any problem for a whle. I tried to use the resource monitor to trace the disk access. I found that "svchost(LocalSystemNetworkRestricted) ... C:/.../lastalvie1.dat" would apear every one second.

In the last week or so my computer has been restarting itself without warning whilst playing video games. When I reboot I get this notice: "A problem caused windows to stop working correctly. Windows will notify you if there is a solution."

I experience the "identifying 'network'" only when I sign on automatically, yet I do have an internet connection and networking works flawlessly; when I sign on manually there's only a very brief instance of it and after that all is normal. After literally spending days on this and trying all sorts of configurations for the router I still can't avoid this issue when I set networking properties to connect automatically.
Got a late model Dell PC/Vista Home Premium 32 which connects with no problems to my AT&T dry loop DSL Siemens 4100 modem which is connected to a new Linksys WRT54GS router which is picked up by an HP laptop/Vista Ultimate 32 with BROADCOM 802.11 b/g network adapter and NVIDIA nforce networking controller. As far as router configuration goes, I have tried the following applicable settings; Automatic Configuration-DHCP, Mixed Wireless Network Mode, Wireless Channel 6, SSID Broadcast as enabled and as disabled, Security Mode as WPA Personal and as WPA2 Personal, WPA Algorithms as AES, TKIP or AES+TKIP respectively. Also I have tried various connection scenarios in Wireless Network properties. Again the bottom line is that while I do have a network and internet connection, I can't sign on automatically without the constant "identifying 'network'" issue and when I sign on manually all is well. Never worked with a router before, Linksys customer support is an absolute trip with no destination and I'm hoping someone here might give me a few clues.

who is not pc literate seems to have a trojan. It's difficult to tell as I don't live nearby so have been unable to look at his laptop. My sister-in-law visited at the weekend and tried to download some media software and half way through she told my dad it couldn't be done and left it. Since then he's been unable to access the internet - error message "IE has stopped working" and the laptop just continually reboots. He is running Vista Home.
Somebody else had a look and told him he has a trojan. He can't actually get the laptop to start up so that he can run an anti-virus (not even sure if he has one). I need something simple and easy that I can talk him through over the phone. He has contacted PC world but can't afford their health check at the moment.

When I start it, it will go to the desktop, everything will run fine, then suddenly nothing can be clicked, and soon the cursor also freezes. No chance to Ctrl+Alt+Dlt or bring up task manager. This freeze was initially happening after about 30 seconds, but after taking out one stick of RAM it lasts as long as 5 minutes before freezing (may be coincidence). This started happening before I changed any settings, the PC is still as new.
I have tried taking out the RAM and putting back in, leaving one stick out as mentioned above, and having a look at the BIOS on startup (didn't really know what to look for though). Made sure everything is plugged into PSU, everything looks right, I'm truly at a loss as to why this is happening. Oh, and freeze doesn't happen in Safe Mode, which leads me to believe it's nothing to do with hardware and is related to Vista or drivers?

i have found over the past few weeks my system has been locking up in the first 10 minutes or so. All i get is a whit screen and a constant freeze out that is not resolved by ctrl alt del. I have taken the following actions
1. took side off case and removed any dust which was minimal
2. cleaned down heatsink
3. removed plug in Graphics card as i noticed it was very hot (GF8400GS)
4. reinstalled Vista ultimate from scratch
5. left the system running with the side off
alas it is still crashing in the first few minutes or wehn i try to install anything. The system is currently clean with just the install software given it crashes as soon as i try to do anything. It is 8 months old and in very good condition. I am at an absolute loss as to what could be. As stated before i cannot run for more than a few minutes so am struggling to do anything with the system....

Is there anyway that I can keep folder sizes to remain constant? For example, in my documents folder, I like the folders to be large, however at times they will be small or in list view. Is there anyway to set the size to remain large no matter what?

My router has been blocking a steady stream of UDP packets from the same four IP addresses. This has been going on for several days now. Here is an extract from the router's log. This same sequence repeats itself "ad infinitum" ;-)
[INFO] Sun Apr 20 15:25:11 2008 Blocked incoming UDP packet from 207.118.109.219:50197 to 76.xxx.xxx.xxx:38043

[INFO] Sun Apr 20 15:24:53 2008 Blocked incoming UDP packet from 71.54.69.146:14853 to 76.xxx.xxx.xxx:38043

Just in case, I rebooted the router and the computer... same results. I also checked SANS to see if there was any new activity and none was noted in relation to these ports.

6 months ago i bought a new lappy and its been going really good with vista on it, no crashes of anykind that i can remember, but last week its just started playing up, Whenever i do anything explorer crashes, sometimes it resets itself and other times i have to load task manager and Run explorer.exe to get my desktop back. anytime i load IE7 it resets itself or anytime i load a new page it does it. It does it when i load explorer (file viewer) and within 10 sec it crashes and closes that with no error box or anything, simply resets or crashes and dosent come back. Same with control panel etc. i've tried my nod 32 virus scanner is up to date and i've run a spyware scan but its still crashing constantly. When i first load windows a missing file error pops up that never used to aswell, but its a different file missing each time i boot up.

Just installed my 3rd system onto Vista Ultimate x64. However, there is now a constant problem of when trying to execute downloaded programs (ie AVG, latest Directx) the application just crashes out in an AppCrash error. I have tried the UAC and permissions and SAFE MODE but nothing. I have read through varius Techs by MS but to no avail and have even done clean re-installs but still the same problem. I have read somewhere that Vista likes different files to be ordered, is ht correct and would anybody have an idea of what is happening?

I'm not sure exactly where to post, but I been getting constant reboot after bringing my system out of suspend/hibernate or power saver mode. It just reboots like its about to post, but then goes back down. It does this over 'n over until I cut the power and kill the PSU. I did have my system OC'ed, but at the moment I'm currently running at default settings.

I looked for posts dealing with RAM and had trouble finding, I thought everybody had problems with slow PCs. Now i need some advice please I have a Vista that is 1 1/2 years old and it had become really slow. RAM is high even when all applications are off and Firefox can use up to 1GB of memory and I have 2G/, I used software like RAMboost and did the long OnceCare scan with MCS, defragmented drives, increased the memory that can be used as RAM on the hard drive. etc.....many things recommended. still same nothing is changed after a short while. Is reformatting and bringing back to how it was when I bought my only hope? And should Firefox take a bloody 1 GB of RAM alone? I checked the processes in task manager and it seems I need all of them somehow and if that was the case if I reformat then wouldn't the same thing happen again?

CPU is running a constant 50%. I have only had this computer for a month and at first it did not do this. then it started every couple of reboots then almost every reboot, but for a while i was able to boot to safe mode and tool around for a bit and then reboot normal and everything would be in sync. I can tell when the comp is booting up if the CPU is going to act up or not, the circle thing by the mouse during the boot up gets jerky and the intro music will be off from the visual..
i have tried turning off the OC but this has no effect. i have to have the OC or the system severely lags. right after this started if i would adjust the OC level it would have some effect ie.. make the cpu normal but now i can do what ever i want and it sits at 50%. While this is happening there are no apps running. and the standard processes but none using more than 04% of the cpu......

I have ran the Microsoft conectivity test many times on my new Netgear DG834G V4(firmware v5.01.09) and it fails on the TCP high performance test(see screenshot attached) I like my Vista tweaks and always had it set to highlyrestricted with my old Tiscali standard Siemens SE587 receiving speeds of over 7Mb on a 8Mb connection almost everyday.
Some of my DSLzone forum buddies have said that theirs passes the test but why does mine fail. I have asked Netgear support and they cannot tell me whether this router supports this feature or not....what a joke!
here is the link to the connectivity test for all routers but you must use Internet Explorer; {url}
Please try and solve this mystery for me. I have just recovered my system recently and it still fails the test so its not my computers set-up.
I will try and attach it seperately this time.

i have installed and updated all my drivers. i got IDT High Definition Audio CODEC. my problem is that my Volume Level in Control panel-Sounds-Recording-Microphone(Properties)-Level, goes down when ever my voice gets louder. is there a setting or a program i have to get through to make it not automatically lower it self? i Already Unclicked "Allow applications to take exclusive control of this device" from Exclusive Mode. this only happens on MSN and maybe other programs that are similar. but not on Ventrilo.

I want to buy the alienware M15x, I want to configure it so it has a 1GB ATI Radeon™ Mobility HD 5730 and a Slot-Loading Dual Layer Blu-ray Reader (BR-ROM, DVD+-RW, CD-RW)which will make the Lappy $1399....Would it be able to play StarCraft II when it comes out? Diablo 3? Sims 3? World of WarCraft? All of these games at high settings? I love video games, but I don't play high demanding ons such as crysis or other games like it, pretty much the posted games above are what I play. Is it worth the price? and will it last me for many years graphics card wise? can the video card be replaced if i want to upgrade? if so how much

i am trying to watch videos in hd on Internet or episodes of on-line shows in "high quality". they are just using flash player 10. i understand i don't have a very fast connection (1.5 mps) but even if i pause the program and let it load, it still stops every 30 seconds or so and i get the "little circle of dots" is this a graphics issue? is it something else? is it my connection speed? i would think if i let it load first i should be able to view in higher quality.

I have a new Dell Studio XPS desktop that is running vista 64 bit. Love the machine...it works great. However, the hard drive loses free space on a daily basis. I've been working with computers for about 14 years and this is the first time I have had anything like this happen. Last night is a perfect example of what I'm talking about. I was going through my library of music files deleting duplicates(to open up space). When I went to bed I had about 45 GB of space open on my HD. This morning/afternoon when I got back on the computer, I only have 35 GB of space available. I'm not d/l anything, the only thing that was going on was that Itunes was running, playing music from a playlist. There was one new system restore point from sometime last night, but that only accounts for 1.5 GB at most. I have really only used WinXP since about 2001. I did have a new computer last year with vista, but hated the performance and switched it to XP. Any ideas on how I lost almost 10 GB of space overnight? Is it a vista issue? A system restore issue(currently set to automatic)?

I've been doing internet speed tests and I consistently have ridiculously high latencies. Like 500+ ms latencies. It wasn't like this a couple of weeks ago and the two other computers in my office don't have this problem. So I figure there's something wrong with my computer. Most likely a software issue but I just can't figure out what it could be. mI am connected wirelessly but so is every other computer in my office so its not that. And I've switched out my wireless adapter and wireless router so I've ruled that out as well.
