Welcome to PCWizKid’s Tech Talk. Today is PCWizKid weekly answer back episode number 2. We’ve got common questions from you guys and I’m about to answer. Here we go. ‘Is it safe to remove all the files in the dllcache folder?’ I’ve been getting that a lot, based on one of my tips. Yes it’s safe, you just need to back up the folder if you’re not sure. There’s lots of files in there. Some of them are very old, never used, you might as well delete them. If you’re not sure, make a copy of the folder, back it up, reboot the machine and then check. So the folder that I’m talking about here is the C:/windows/system32/dllcache and you can see here the folder and I’ve got a whole bunch of files in there from 2004. So I’ll just highlight the 2004 files and then just delete those. Gone. Now I do have files from 2009, I’m not sure about those. I’ll make a backup of those, copy them somewhere else, delete the whole folder then, and then reboot the machine. And then if everything works fine, then I can delete the backup. Now here is another question. ‘I have 4GB of RAM installed, why does my Windows OS, why does it only show me 3GB of memory?’ Well that is because 32-bit Windows only recognizes up to four gigs and if there are devices installed that are occupying certain memory areas, then it’s only going to show 3.5 or three gigs or even less. So that’s normal actually. If you have 64-bit Windows it will show you the full amount. Ok, so just keep that in mind. Now depending on whether you have Windows XP or Vista, the areas that it shows you under ‘My Computer’, for example or in the ‘Control Panel’ looks slightly different. But that is basically it. Just keep in mind that this is a memory map reservation issue ok? That is known to Windows 32-bit Operating System especially so even though, this is not dependent on Windows. It is a 32-bit issue ok? And depending on whether or not you have a video card, or integrated or not, it’s going to use that memory as well. Ok, now another question is, ‘Can I uninstall Internet Explorer?’ Now we know that IE Six and whatever before that came integrated with the OS makes it very difficult to uninstall and remove. As IE Seven and IE eight came out, it also was a little bit difficult to remove because when you went in to the ‘Add / Remove Programs’ to uninstall one version, it would then leave you with the previous version, right? So that kind of defeated the purpose. So keep in mind that it is a little bit tricky to have removed but you can go into the Windows components and try to remove it from there. If you don't see the ‘Internet Explorer’ option under the ‘Add / Remove Programs’ in the ‘Control Panel’, it might be because you have for example ‘Service Pack Three installed in Windows XP and you’ll have to uninstall Service Pack Three in Windows XP in order to uninstall Internet Explorer, ok? Alright, now another question that I have is, ‘Where can I get the music that you have in your intro?’ So all my music that I use, is free. It’s under the Creative Commons License available from incompetech.com, ok? So you can go ahead right there and download the music, such has a GearHead.MP3 that I use in some of my videos. Now another common question that I have is, ‘How can I increase my integrated video card memory?’ So that’s a little bit trickier. Not all BIOSes are the same but generally you would go on to your BIOS and look for the ‘Integrated Profiler’, ‘Video Card’, ‘Integrated Video Card Settings’ and then through there, you would see a shared memory amount that you can allocate. So 64 megs or 128 megs or even higher. So just go to your BIOS, look for screen similar to this one and then you can adjust the shared memory size and increase it, ok, from there. That’s all I can suggest for you. Screens are slightly different depending on the BIOS you have. So keep the questions coming, and I hope you enjoyed this video and thank you for watching.
