Understanding IRQ Assignments And Troubleshooting
Sep 14, 2008
I've been going over and over trying to solve a problem on my PC for the last few days, and while it's not an issue worthy of another thread, I do have some questions that you experienced guys might be able to either explain, help or point me towards understanding. I'm pretty fluent in computers, I've been building them since I was 9 years old, so that makes about 21 years worth of seeing things break.
One element that I never really got into, due to not experiencing, is understanding and troubleshooting IRQ conflicts. I have a massive list of entries in my device manager, and some of them share an IRQ entry with other items. Would I see any improvement in stability by putting, for example, the video card on its own IRQ channel, if my PC's only problem is freezing shortly after launching a 3d game? My video card is actually sharing an IRQ assignment with the 1394 and 4 USB controllers.

I've installed a 320 gb disk in place of my full-up 80 gb disk. To make room for W7. Now I'm formatting it into C: and D:, running from a CD. But since the CD is D:, the 2nd partition became E:. I am using software from StorageCraft to restore everything - boot record and all. But my 2nd partition must be D: for my installed software to work. How can I change the partition letter assignments?

Given an internal drive with multiple Vista installations how do I change the drive letter of the boot drive of an installation?
Best explained with an example. Given:
Partition 1: Vista 1
Partition 2: Vista 2
Partition 3: Vista 3
etc.......
In other words, Vista seems to insist on the currently running system living on C: (like in the olden days). I thought since W2K Windows can be installed on any drive e.g. my old system has W98 on C: (no choice there) but W2K boots from and stays on D:.

I am getting intermittent memory error message saying the pc has run out of memory and trying to track down what is causing it. When I boot up the pc I see Physical memory of 3.325 Gb and used memory of 1.04GB 32% in task manager. When i go to Resource manager I can't understand which of the different types of memory (Commit, working, private) make up the 1.04 reported as used. If I add up all the processes under Working Set it only comes to about 600Mb. So 2 questions:
a) Are ther other OS processes not listed in resource monitor that are using up the unaccounted 500Mb?
b) Is Working Set the right type of memory to be monitoring to see which p[rocess is causing the reported % usage to climb so much?
I'm intending to writie down each porcesses usage every 24 hours ot try and identify the culprit. Strangly the problem has only appeared since i increased the RAM from 1Gb to 4GB!

I've put together a number of apps for anyone who doesn't know their specs or needs troubleshooting info. The archive contains Belarc Advisor, Process Explorer, a shortcut to dxdiag, and a .bat file that will list all the drivers and their dates. There are also 3 guides, 2 of which are in my sig, the third is a guide to event viewer.
There is also a readme for getting your system specs and uploading them here as well as a brief intro to the apps. The archive is an SFX archive, so just double-click and choose where to extract the diagnostics folder. Any feedback would be appreciated - or complaints.

I am new to Vista, and definitely not in league with the pros, but I have gone through all the gaming posts, and followed the suggestions for downloading updates, especially the SP1. Here is my issue: Despite troubleshooting; updating all drivers; downloading and installing SP1, and performing all automatic updates, I still receive a critical error message regarding virtual memory, which crashes the game after the first level, when loading the second level of the game.
My system is a HP Pavillion dv9500; windows vista home premium 32 bit OS; AMD Turion 64x2 1.90 Ghz; 1938 MB RAM; I changed the compatibility to those recommended for win 95 games; have increased the virtual memory via custom settings to the maximum of (1938 x 3) allowed per system. I love this game, and really want to play it on my laptop, but at this time, I do not have any free money to upgrade or purchase or make changes in hardware, etc. Does anyone have a fix for this?

I bought a computer last year with an OEM version of Windows Vista Ultimate x64. I needed an additional 4GB of RAM and I was having problems with the computer not booting up. After posting in the memory modules manufacturer's forum they told me to alter some parameters in the BIOS regarding memory timings. After some experimentation, the computer would not even post to BIOS, so I decided to clear CMOS. Now, every time I boot into Windows, it asks me to activate and if I activate it, it tells me the license is already assigned to another computer. I contacted Microsoft support here in Portugal and I already tried telephone activation and System Restore as specified in the troubleshooting for activation, with no luck. After contacting Microsoft support again they told me to post here in the newsgroups to try to find a solution, otherwise they would have to bill me for telephone support.

I have a fairly new PC running Vista Ultimate. Last week I noticed tha tthe HD in Computer reported only 3GB of the 137 available on the primary C: partition of my drive was available. I've been trying a lot of troubleshooting to figure out what's eating my space Here's what Vista Disk Manager show: Here's what another utility show: On the latter, the large, grey area seems to be the issue. THe Lenovo utility says that it has not scanned that part sue to insufficient authority (I am the only user and has Admin privileges on this machine). So how can I go about determining what is eating 74GB of my harddrive?

I am experiencing a number of Reliability and Performance Logs, and Task Scheduling issues and difficulties.
In trying to troubleshoot the problems, I have started with the Task Manager, as it is clearly not performing at all.
First, before starting this process, I created a new Restore Point.
Then, at Start>Help and Support>Select, ?Troubleshooting>in Search Help box type, Troubleshoot Task Manager>Select, How do I enable Task Manager if it has been disabled. ....I end up with this set of troubleshooting instructions;
Using Administrator Rights, I am able to navigate down to Step 3 of the instructions,[see string in bottom panel] here;
Before going further, per the instructions, I saved a copy of the Registry Key to a hard-drive.
With that done, I tried to double click on System, but nothing happens! Disable TaskMgr does not come up to allow me to continue with the troubleshooting process.
