Windows 7: Games and rundll32 issue

15 Jul 2010   #1

Games and rundll32 issue

Hey guys

I'm new around here. I recently installed win 7 ultimate (I had vista previously) and had some considerable issues (bsod, driver issues etc.) I managed to resolve the bsod by installing a new 56k modem (no adsl in my area)

So after about 3 re-installs of 7, I thought I had everything sorted. However I noticed after connecting online one time, from the reboot afterwards, none of my games would work. My games would open with about 1000kb of ram and 0% cpu but a rundll32 process would start up and use 50% cpu... doing nothing.

I re-installed 7 but after connecting online once again, from then onwards the same issue arose. It's as if 7 is downloading something that messes up my system. I've turned off all updates (windows update, games explorer, windows media player etc)
I don't have an anti-virus installed. I think other software is doing the same thing (third party software eg. video editing software) Any ideas?

I don't have an anti-virus installed.
That and having windows update turned off is just waiting for trouble. If you look over in the security section you will see an article stating that Microsoft Security Essentials, which is free to everyone, is one of the best AVs out there and worth installing.

Now the main issue. What games are we talking about here? For some of my games I have to use XP mode, but its mostly just Doom 1&2 and other old as dirt games. It definitely seems like a compatibility issue to me. But I can't find out unless I know specially which games you're using.

EA games (Needforspeed Underground 2, Carbon)
Quake II

I can manage to get Q2, Halo and Portal working sometimes If I open the .exe a few times and run-as-admin after killing rundll32.exe

What's weird is that all my games were working perfectly fine before I connected online (about a week after installing 7) so it's not so much compatibility but rather 7 doing something on its own accord. I've tried running everything in compatibility mode (Xp and Vista)

I'll try installing some newer games (Fallout 3, Fear etc.) however I have already tried Halo 2 (which installs but hangs when I try to load a level)

Based on my experience with playing Halo and The Sims 2 (an EA game) with no issue, I would say you have a virus of some sort. I also just saw what you wrote about 7 trying to install something. Reactivate Windows updates and update your machine (this might actually solve the problem by itself if a patch from Microsoft is all that is needed). Then download and install MSE if you are able to do so. If some weird error occurs, it is probably a virus preventing you from installing it. I know it sounds weird, having a virus after going online one time, but it is not unheard of and I've seen it myself. After installing MSE, let it run a scan. Please write back whether it solves the problem or not. We like to know the results of what we recommend.

Okay, think I found a way to fix this. I won't go into too many details about what causes it. Go to the start menu. Click all programs, games, games explorer. If a pop up does not happen, click options. Set it to not check online for updates, and uncheck the two boxes about collecting info for your games. It seems that when the a certain dll tries to collect the info from the internet it starts an infinite loop of sorts. This should solve your problem. Please write back with the results of doing this.

you have a virus of some sort
I only have access to dial-up so I was unable to download MSE, however I was able to not only install but run ESET, avast and AVG (which I had access to). All returned with a zero virus result (they picked up some self-modded files which aren't harmful) So I think it isn't a virus.

think I found a way to fix this
This was the very first thing I did prior to first posting on sevenforums. Infact it was the first thing I did after installing 7 the second time. It did not resolve the issue, and when I connected online- the same issue arose.

Since I'm on dial-up (there's no adsl in my area and I only live 10 minutes from the city centre in a first world country lol) windows updates are a sort of no-go-zone for me. The only workaround I've discovered is this:

1.Run the game
2.Terminate the game using task manager
3.Run the game as admin
*Game opens
4.Alt tab and terminate rundll32
*Resume game which plays with proper cpu usage

Running the game as admin first off does not resolve the issue.

Thanks Petey for your interest mate. I'm really stumped on this one; it's more of a nuisance than a life-or-death situation but I have no idea what's causing this.

Windows 7 Ultimate x64

Only problem is because Windows Game Explorer recognize it as Windows game, and cannot open it !!! See in Game explorer or type: shell:games in the Start Menu, and if there are non Microsoft games delete it (explained in: Games Explorer Folder - Delete a Game) but it ain't easy at all and windows will place them again there !!! (and you have same problem without end !!! -Easiest way (If game allow) to rename same game (.exe), game in install location, not shortcut ! as example: SPEED2.exe (what is NFSU2) to any XXX.exe file (Tested on most problematic games as EA NFSU2 and more !) and periodically check did the game explorer "catch" it and put it again in own list, if is so, rename it again !!!
