Higher CPU Usage Due To Deferred Procedure Calls (DPC)
Feb 10, 2010
Running Windows 7 64-bit and just downloaded the lastest updates from Microsoft last night. Now my CPU is sitting at 20% due to Deferred Procedure Calls and Interupt Service Providers running constantly according to the resource monitor. What could cause this issue? Could it be a driver that downloaded from MS? I believe the fix for this would be to just restore back to before the install but I have a question about restore points. When I open up the restore point menu and it shows all the dates, do I pick the date of the MS update or one day earlier?
Recently I have noticed higher than normal CPU usage from my laptop which I know will reduce battery life, cause higher temperatures and slow the computers performance.The task manager did not tell me too much so I decided to have a look in the Resource Manager.Sure enough under the CPU tab of the Resource Manager there is a process called System Interrupts that has a description of "Deferred Procedure Calls and Interrupt Service Routines" with a average CPU usage of about 30%.I did notice that when I first turn my laptop on and boot in to Windows that this process uses about 1 - 5 % CPU usage and my temperatures stay at about 28 - 32 degrees Celsius.Usually after some time of using the laptop I notice this temprature rises to about 48 - 54 degrees Celsius and when I check the process it is using around 30% CPU usage, usually to resolve this I restart my laptop and everything goes back to normal and the process is back down to 1 - 5 % CPU usage.I done a little research online and found that clean boot of Windows may solve the problem, I did this then re-installed all the required drivers from my system manufacturer, installed Avast Antivirus Pro then done a Windows Update.
Just today I decided to update my IE8 to IE9 (Win 7). There was also an unknown windows update to install (today 15th Jan 12)). As soon as it was installed (without even opening IE) my system is now using 25% more ram (about 700 of 1G compared to around 500 before). I uninstalled IE9 and went back to 8 as shown on the microsoft page, but as soon as i start windows its using 700 again. I tried rolling back to an earlier point today and still have super high ram usage. Now with just this single IE tab open im using 900!
which in your opinions is better? a higher resolution and lower textures and details or lower resolution, but higher textures and details. the highest resolution i am able to achieve is 1366x768. so nothing past there?
Each time I right click, in say explore or search type program..like everything for example, my computer tries to configure/install acrobat. I guess there is something left over somewhere from maybe windows installer or even adobe installer.
I have a fax modem pci card that I use to send the occasional fax. Is there telephone software somewhere in 7 that would enable me to use the card to make telephone calls through the pc and use the pc as an answering machine ?
All I want to do is make and receive land line phone calls on my pc. NOT VOIP. Using a USB headset and USB voice modem. Please can you tell me the specification I need for the modem and suitable software to make it all work?
I am thinking of re installing window 7 onto my laptop, which currently is on window 7, but of a different language. I would like to install an english version of window 7.
When addressing an email, I begin by clicking on "to". Then the list of contacts appears and I have to click on the contact's name, select from "to/Cc/Bcc" and then click on the 'okay'. This seems to me to be a rather laborious procedure. Is there a way to modify WLM to simplify the addressing procedure. For example, after selecting (to/cc/bcc), a single click on the contact adds the addressee without having to move the cursor over to the far end to hit "OK"?
I have a 22' monitor with a resolution of 1680x1050px.When I am working on my pictures for example in Adobe Lightroom the UI is very big and it lets about half of the monitor space for the actual image... I know that people having bigger screens with higher resolutions have the UI MUCH smaller, and I also know that the screen resolution is physically limited so I don't want to set my resolution to for example 2560x1600px but I want to decrease the size of everything on the desktop... Like just scale it down like you can do with the icons with simply holding Control and rolling the mouse when but with the whole desktop, the mouse, the UI, the start, etc. etc.A good picture of what I am trying to achieve is when you set the DPI to 125 or 150% but I want to set it to like 50 or 75%
I'm getting an eVGA e-GeForce GTX 285 soon, and I currently have a BFG GeForce 8800 GTX in my system. I usually uninstall the graphics driver I have installed, and then swap the card and install it's new driver. Is there any other "better" way, or is that pretty much the standard procedure?
Is a registry sweep recommended to get rid of any remaining driver components? Do you recommend any programs to do this?
I'm having major trouble with my audio card driver (M-Audio Delta) so I wanted to uninstall it. I went to "Programs and Features" and click uninstall. It immediately gave me this error:[CODE]
I recently upgraded from Vista Ultimate 64-bit to Windows 7 Ultimate 64-bit. I have a problem with the resolution now. The monitor I use was supported in Vista for resolution 2560x1600 but now the highest I have is 1280x800. I can't get it any higher, when I go back to Vista /same Dual-link cable, same monitor, same PC/ it shows 2560x1600 correctly, once I go Windows 7 - it only displays 1280x800. I have tried every driver update /Dell monitor3007WFP, ATI Radeon HD6950/ but nothing works. I first thought its my monitors' driver problem but after I researched online, it seems that many people have same problems with the resolution once they go Windows 7 /no matter the pc or monitor brand/. How to able to run this at 2560x1600 resolution.
Slow Respond in games on higher resolution such as 1366x768 or 1024x768

When I insert USB Drive, the folder just load but its not opening at all, plus all the icon was gone. I have done scans for both malware and antivirus but none found. The only solution for this is when I remove the drive and restart the pc. I also experience this when sorting items without the usb inserted. After this problem I often get "The remote procedure call failed and did not execute." Which restart is the only option.
Microsoft says you need a "DirectX 9 graphics device with WDDM 1.0 or higher driver" for Windows 7. How can I tell I have the proper one? I have a GeForce FX 5200 DirectX 9.0.
I purchased the Windows 7 Professional upgrade version through Digital River and I have been trying to install Windows 7 since last night with no luck. I downloaded the ISO file and EXE file with absolutely no luck. I keep getting an error that my current version of Windows (Vista 32-Bit Home Basic) is not compatible with the version I am trying to install which is Windows 7 Professional 64-Bit.. I tried Paul's three methods with no luck =(. The second method gives me an error message that higher privileges are required to do this.
Why isn't my computer reading any of the Windows files as a boot disk? I hope I downloaded the files correctly. I did burn the ISO file to a disk but still no luck. I am so frustrated abd honestly had I known this was going to take up so much time I probably would have just continued suffering with Windows Vista which i absolutely hate with a passion.
I recently got a new 120gb SSD to replace my HDD. I have an i7 Lenovo y570, 8gb ram, with switchable graphics using a Nvidia GeForce 555m. Before upgrading, while playing Guild Wars 2 my performance was flawless on ultra graphics running at about 80 C and stable 50 FPS. Now I'm experiencing spiking FPS running at about mid 90's C after 5 mins on the lowest graphics settings! I updated all drivers and installed it correctly to the best of my knowledge.
I've a problem to install any software on windows 7. I cant even install games which is compatible with wins 7. This message will appear when I want to run/install a software. "The specified procedure could not be found".
i install autocad 2007 on my hp laptop notebook size, i try to open it, i cant see the other command below because the window is not fit tot he screen.
I have a ACER D255 netbook with intel atom N550 (1.5ghz, 1mb L2 cache) 1gb DDR3 memory and 250 gb hdd. lately it has been a tad slow and freezing up will using google chrome. my task manager says right now that CPU usage is 4% but Memory is at 75%, sometimes up to 90%. it also says that i have 89 processes running.
Since about a couple weeks ago my computer has been working fine. Then when i woke up on March 25, the minute my computer started i received an error message. I thought everything was alright but when i went to open my browser i received the message " The procedure entry point _except_handler4_common could not be located in the dynamic link library msvcrt.dll." and "The procedure entry point _ftol2could not be located in the dynamic link library msvcrt.dll.". Everytime i try opening a programs like Photoshop,Word, Malwarebytes and ESET... it gives me that message(I tried dowloading and running rkill with different names but the message also popped up). Strangly I can still open SuperAntiSpyware and open games like Chess. I have tried running Microsoft Security Esssentials with no results. I have tried running SuperAntiSpyware in all modes (including the rescue scan) and it said that everything is clean. When i clicked on something that was only avaliable to the paid version my internet browser(Internet Explorer) popped up(So i think its like the Security scam that does not let you use programs).
My computer had a bit of a melt down and now I think it best just to start from scratch. I am going to re-install the O/S on my Toshiba Satellite L500-19x.I use Dropbox quite a bit. Do you know the 'proper' way I should handle the process in regards to Dropbox? Will others lose access to my 'shared' folders when I do this?
I keep getting the The Remote Procedure Call Failed and did not execute error when opening my control panel or windows explorer on Windows 7.I've made sure the RPC is on and that the second service is on manual so that isn't the problem.
I am trying to play a game I used to play nearly ten years ago. It's a free online game called Continuum/Subspace and there are user created "zones" or variations of the game within the game (if that makes sense). I play in a zone called Trench Wars. It's a top down game, meaning you are looking down at your ship as if from above and the screen scrolls as you move to reveal more of the area (map) you are playing in. You are in a spaceship of your choice with varying weapons for each ship. The game requires aiming at your enemies before firing at them and anticipating their moves.
Well I noticed that playing at a higher resolution allows you to see more of your immediate area and expands your view of the map. It works just like your desktop in essence. The higher the resolution, the smaller the icons, but the more space you have. In the game, the higher the resolution, the smaller the ships are, but you can see more space around you. Obviously, this would give an advantage to anyone playing on a higher resolution, as they would be able to see their enemies and fire before the enemy even knew they were there.
My native resolution for a 32" LCD TV is 1360x768. This is fine except when playing continuum. So I tried changing my resolution to the max which is 1920x1080. Well the screen expanded and cut off parts of my screen, everything got blurry, and had a blue tint to it. I figured this is probably not good for my TVs functionality, as I have burnt out old monitors in the past by running too high of a resolution. So I went to my NVIDIA Display Properties and started messing around. I realized that changing to a higher resolution (1920x1080) from here still caused me to lose part of the screen, but the blue tint wasn't there.
It's still vaguely blurry, but not enough to really notice. So I went to the resizing tab and resized. My screen to fit at the higher resolution. I ended up with resolution of 1842x1036 at 60HTz refresh. I resized my icons and text and the screen is perfect now. But, it is much higher than the native resolution of my monitor. So my question is, will keeping it at this resolution cause my TV to "burn out" or have any otherwise adverse effects?
