Dllhost.exe Constant 50% CPU?
Sep 29, 2009
I just did a clean install of Windows 7 Ultimate x64 and I have a new problem:dllhost.exe (COM Surrogate) is constantly taking up ~50% CPU, I don't have Nero installed, the only things I've installed so far are:
Windows Live Messenger + Plus! by Patchou
Firefox
Alcohol 120%
WinRAR
nVidia Forceware(newest)
Drivers for my E-MU 1212M soundcard
In the middle of an installation of Adobe Creative Suite(but the problem was before I started installation).UAC is on.

I keep getting " Runtime error Program: c:windowssystem32DllHost.exe
This application has requested the runtime to terminate it in an unusual way."
I can close this window but it reappear in a few seconds. It seems that it is not affecting my system at all but the window is really annoying.
If I create a new user it resolves the problem but when I run Windows media Player the error appears in the new user.

each time I open a folder containing videos with big size my dllhost.exe uses an enormus quantity of RAM making my computer freeze. I have a 3gb of Ram and a Quad Core Q6600.
I first thought it was because of my codecs, so I removed them then reinstalled again K-Lite Codec Pack, it didn't work so I removed the K-lite again and just installed FFDshow (like someone said on a forum), it didn't work, so I installed Kasperksy Internet Security 10 (trial version) to check if it's a virus, no virus detected ...
I also stopped the UAC.
What can I do now ?

I'm having problems with my system, I can barely go 10 minutes without having to restart my computer because of DNS failure. I've restarted my router, changed my IPv4 DNS location, etc. And I've had no luck.

I made the switch to Firefox from IE8 and i'm highly considering going back because of this annoying and disrupting error message. Take a look at the screen shot and give me a holla at what to do.

My laptop has been getting the BOD several times a day and reboots itself constantly (been going on for over 2 weeks). The Blue Screen always indicates BUGCODE_USB_DRIVER When I look at the dump files, this is usually indicated Caused By Driver : usbhub.sys Caused By Address : usbhub.sys+Laptop details: Windows 7, 64-bit OEM I had to do a reinstall of Windows a couple of months ago after the laptop crashed after a Windows service pack 1 installation. ASUS U50F series, 2 years old have included two different perform reports one from the night after the computer has been on all day and one from the morning. Ive noticed that the report is usually different.

I had a thread before with some blue-screen errors, mostly memory errors, so upgraded my RAM (8Gb DDR3), installed a new operating system (32bit to 64bit) and on the first boot-up: CRASH.

I have an acer Extensa 5620Z laptop and recently, without any warning it just restarts. A blue screen appears out of nowhere and then the computer restarts. When I was able to choose how to restartt I chose safe mode and went to the event log where it said "The driver detected a controller error on DeviceIdeIdePort2.". I have no idea what this is and I've seen a bunch of stuff talking about reconnecting thing and adding new roms

I'm new to this forum, so please forgive me if I make a mistake.I recently purchased a Dell Latitude E4300 refurbished laptop from a seller on eBay. Ever since I brought it home, it has been constantly freezing randomly, whether it be whilst I'm browsing, navigating through windows etc.I've reformatted, and completely wiped the system about 3-4 times, installing different versions of Windows 7 whether it be Home Premium x32 or x64, or Windows 7 Professional x32 or x64 bit, but regardless of what I do, it concludes pointless. I first suspected it was the graphics driver, hence I've tried updating, and downgrading the driver to see whether it would rectify the problem. After that appeared pointless, I suspected it might've been the fan, as the computer does heat up quite quickly, however that concluded pointless as the computer froze even on the windows 7 boot logo. Finally I suspected it might've been the hard drive, and/or the ram, I did some tests (Windows Memory Diagnostic & Memtest86+) and CHKDSK multiple times without any detected errors being found. What I found interesting was that it mainly froze when I initiated a "Windows Experience Index" test, however that was at the beginning.

I have 7, 64 bit, running on an HP and have been keeping pretty up to date on my drivers.amd a4 3300 processor with graphics card, and 4 g ram.When trying to use menus, the window or entire screen will seem as though it refreshes, closing the menu, i can watch the bar across the top of windows flash as if it had just disappeared for a split second and the menu is gone, leaving me to reopen it, but at a second or less between these refreshes I have to be quick on the pointer to get to what I want. It seems to happen on any menu item, including all drop downs, wether im right clicking a start menu pined item, a choice dropdown on a webpage, a setting dropdown, etc. it doesnt alwasys do this but more often than not. It seems like I can sometimes restart the pc and it will work, but it often will do it right at startup. I hadnt noticed it til I connected the VGA out AND the HDMI out to the same tv (dont know why I did it at the same time, I think to compare the cropping). Also, I used system restore to go back to before a bunch of updates and it seemed to fix it, but that might just be because the pc restarted in the process.

I'm getting pinged constantly and I don't know what program is doing it. Is there a way of listing all my programs to configure which one could be the culprit?

I am using W7, home premium on 1 year old HP desktop computer.Recently, I was having trouble accessing videos from you tube, email and other sites. I had been using adobe flash player 9 and I was told to upgrade adobe flash and to get version 11. I installed version 11 but it would not play until I lowered my privacy settings from medium high to medium per instructions on Adobe. The flash player worked after that except now I am constantly getting the following message everytime I launch IE 9 and every time I go to a web site. The error message is always similar to this -"Privacy Alert The website (AZh).com has requested to save a file on your computer called a cookie. Do you want to allow?Allow or block"I am currently getting this message many times a day. No matter if I select block or allow, they keep coming back. This happens on all sites and often is unrelated to the site I am visiting.

Basically, no matter what browser I'm using (I get the error in IE, Firefox, and Chrome), it usually takes me 5-6 tries to load any given webpage, and even then most of the time the formatting's screwed up, pictures don't show up, etc. I'm using a new(ish) HP laptop that's maybe about 20 feet from the router. The router itself is hooked up to the desktop computer, which never has this problem. My wifi signal is strong, and the indicator in the tray never drops below "excellent" signal strength even when I'm repeatedly clicking refresh. Power cycling the router doesn't work. I've cleaned out caches and histories, even uninstalled and reinstalled browsers with all necessary updates, and still nothing. I called the cable company that provides my internet and they're convinced it's not on their end. It doesn't matter if anyone else in the house is using the desktop with its net connection at the same time I'm trying to use mine. Theirs works, mine doesn't.
But here's the really weird thing: I had this same problem with my previous laptop.In both cases, I can take the laptop other places (school, coffee shop, etc) and never once experience this issue.It seems to have cycles where it'll be fine for a little while (maybe hours, maybe days), and then for a few hours or days at a time I just want to give up and go read a book or something.In IE, I typically get a standard "this page cannot be displayed" type error. In Firefox and Chrome, I tend to get more specific "the connection was reset" errors, often immediately upon hitting refresh. Sometimes the page will try to load, and "Sending request" or a similar message will appear in the status bar before everything craps out. Just as often, the page will appear to be very slowly loading, then parts of it will load but most of it will be an Error 105 message (In Chrome: "Error 105 net::ERR_NAME_NOT_RESOLVED): Unable to resolve the server's DNS address.") Doesn't matter what page it is. Google, Facebook, my school's library portal, reddit, Amazon, doesn't make a difference.
The only other thing I can possibly think of is that it's the router itself that's bad. It's a generic deal that doesn't even have a name; the manual I had to scour Google for refers to it only as "11g Wireless Security Router." But that still doesn't really tell me why the desktop connection works like it should (unless that connection is completely bypassing the router; I'm rather clueless about these things).

I regularly have to go into Options/ Advanced/ Network/ Clear Cached Content to get pages to display properly.From time to time pages will display with just simple text...no images etc...like a failed webpage load. The solution through trial and error has been to clear the cached content.

I've had these issues since I built this computer in about February last year. Programs are unstable or freeze (SC2, Skyrim, even firefox). I get seemingly random BSODs. I can't really define a pattern of when they occur, but it is at least daily.I have reinstalled the OS (Windows 7 home premium 64 bit, full retail version) multiple times in an attempts to resolve. I have 2 HDDs in addition to my SSD. OS is currently on SSD. I had tried installing the OS on the HDDs as part of troubleshooting but ran into the same issues. I wiped the HDDs with Deriks Boot n Nuke before using them as storage.I can run Furmark with no issues. I have run memtest86 with no reported errors. I've run Driver Genius Pro to keep everything there up to date.I believe that is all relevant information. Please let me know if there is any further information required. I have been looking for a definitive conclusion for a long time.

For the past week I've had crashes after about an hour of use. I was getting BSODs that flashed quickly then the computer tried to reboot but would not get past the motherboard screen.Power cycling brings windows back. After enabling a page file I was able to get a BSOD and minidump which wasn�t happening previously.I've tried memtest86 (only 1 pass), chkdsk and windows virus scans. Nothing shows up. I dusted out the internals and monitored the CPU temp and that was normal. The video driver (AMD onboard) was the only driver that needed updating and I fixed that with no change.
Here's my info:
x64 windows 7 professional, homebuilt, about 1 year old.
More details:The first time the crash happen I was running Google Earth for the first time in a long time. Initially web pages stop loading. Then I can�t switch programs or start task manager. Then the spinning rings cursor shows up. About a minute later the computer flashes the BSOD then reboots. Though now it seems to persistently show the BSOD.

i have been spending alot of time on this problem, and everything does not seem to work. i have windows 7 home premium 64-bit, with a AMD Phenom II 945 Quad-Core processor. my graphics card is an ATI Radeon HD 5450, with an intergrated sound card and 8gb ddr3 memory. generaly, a problem arises within 20 mins of gameplay (does not matter if im outside or inside), and presents itself either as a crash-to-desktop or a freeze. also i am not playing with any mods or DLC's or with New Vegas i have tried many fixes; i have set the INI to use only 2 (then 1 processor), disabled all autosaves, downloaded/installed the d3d9 file, changed windows color scheme to "basic", i have updated all my video card drivers, i am not aware of any codecs being used on my system (did a file search, came up w/ nothing), running as administrator, allowed all premissions (its even installed in my documents, NOT program files), and even now i still have this problem. however, i can also play Oblivion w/ about 300 mods and i can play pretty comfortably. on top of that (even though i dont have the most recent games) Fallout 3 is the only problem.

Now on to the issue I have run into.
** I am currently running WIN 7 Ultimate 64 Bit RTM **
Every single time I try to use system restore, it comes back with the exact same error, on reboot:
{"System restore did not complete successfully. Your computer's system files and settings were not changed. Details:
Unspecified error occurred during System Restore. (0xc0000043)"}
I have tried different system restore points, (within Windows), but it does not seem to fix the issue. I have also tried disabling my security software, (KIS 2010), and that doesn't seem to help either.
The puzzling thing is that when I run system restore in safe mode it seems to work no problem, but it just will not work within windows itself, (normal boot).

I am using my iPhone to try to figure out my computer. So it is the only one I have. It is in a constant loop of windows not starting and trying to fix errors then says it can't, I can't get it to load in safe mode or anything else. I can use the box where u put in commands and found my registry hive says 0 bytes. I do not know how to fix this. And I do not have a windows disk cause it came already installed. So how can I fix this and what do I need to do or try.
I do have a Windows 7 product key on the back of my computer.

I have an HP laptop that upon boot-up would show the HP logo and then go to a constant blinking underscore on the upper left hand corner. During the HP logo screen, I pressed f2 to enter "HP Startup" where I scan the hard drive and it passed all the test. Also I can go into the BIOS by pressing f10.
From my research, I changed the order of boot-up and put local hard drive at the very top. I also unplugged the battery. And laptop is still not working. I also read that perhaps putting in a System Repair Disk might work(?) But I just discover that my cd-rom drive is not working. What would be the best way/ or my options in going about to recovering my data?

I've been having this problem for a while now, and I really want to get to the bottom of it. The flicker takes the form of narrow vertical shadows moving across the screen horizontally. It isn't particularly noticeable on lighter backgrounds, but on a darker screen, it's really distracting. I notice it most when play Minecraft (in dark areas) and at darker scenes during DVD playback. I thought it might be that the monitor isn't getting enough power - there's my PC, an external HDD, surround sound speaker system and two lamps running off the same power supply - but I plugged it into a different supply, and still had the same problem.

I'm not sure if this has been posted before, but for the past few weeks, I've been experiencing constant connection drops(I've concluded it that it's the router because both the modem (sb6120) and the router shows the amount of time it's been up) and everytime the connection drops, the router would show that it had just rebooted. Should I reset all my router configurations or is it something else that is the problem?

I installed Windows 7 RC. When ever I am booted into Windows 7 one of my hard drives (probably not system drive - sounds like my secondary storage drive) is constantly working. Not very much but still making sounds.
I have completely turned off indexation, there is no automatic defrag going on. I have set a constant size to the paging file and there is no antivirus activity going on. The hard drive is making noise even when the system is idle for a long time and also when I am using it.
The processes tab in the task monitor shows no process that is using CPU.
What can this hard drive activity be?
