I have a Thermaltake DuOrb CPU cooler and when I installed it, I tightened the screws until I felt some tension, but I’m not sure that was the right thing to do. I have a Q6600 CPU and the temp was 34-36 C at 2.4GHz (stock). I overclocked my CPU to 2.8GHz and the temp went up to 38-42 C (idle). If I overclock to 3.0GHz the CPU gets too hot—55-65 C idle. Is there a proper way to tighten a CPU cooler for optimal performance?
I built a home theater PC from scratch a while back. It has an Intel D945GCZLR motherboard with a Pentium D 925, a passively cooled GeForce 6600, and an Avermedia PCI-e Combo TV Tuner, all inside an Evercase ECE1341 case. I went with the best BTX CPU cooler I could find: the Thermaltake CL-P0191. This thing sounds like a lawn mower.
Even with plenty of airflow into the case and plenty of room in every direction on my entertainment system, the cooler is far louder than the 14-28dBA its marketing materials claim. I have already replaced the cooler’s fan once, but the new one was just as loud.
What can I do to quiet this thing down? Would upgrading to a cooler Core 2 Duo or Quad make a difference? What about upgrading to an actively cooled GPU? Even stock ATX coolers are cooler than this thing—can I just use one of those?
I bought two laptops for my two granddaughters about a year and a half ago. Now both have missing keys. Is there a way to purchase replacement keys, or do I need to buy a whole new keyboard? These two laptops are both Compaqs sold by HP. If I give HP the model number can I get a kit with all the key caps and a procedure for installation?
I’m looking to get a new SSD for my laptop when Windows 7 comes out, and I just read a review on Newegg warning about a drive not supporting Win7’s TRIM feature. A Google search gave me the basics on TRIM, but how important is it, really? I’m having trouble finding which drives support it and am wondering if I should wait before pulling the trigger.
I use my laptop for home and work, so I’d really like to do a clean install on a new drive (for restoration purposes when I really screw something up) and it seems like a perfect time to make the switch. I’m also moving from 32-bit Vista to 64-bit Windows 7, so—as I understand it—I need to wipe regardless.
I recently reformatted my computer after a failure with an old Seagate 7200.11 1TB. Lately, though, I have been noticing problems with my USB ports. Whenever I connect my iPhone 3G, it is very hard for iTunes to recognize it and the popup tells me that the iPhone isn’t plugged in to a high-speed port, even though all my USB ports should be 2.0. This has raised even bigger concerns about my other devices connected via USB.
My motherboard is an Asus P5Q-E. The CPU is an Intel Q6600. My initial thought is that an upgrade to my mobo’s BIOS or other utilities might fix the problem, but I’m wary of undertaking such a feat without knowing for sure what the problem is, because I’ve heard updating the BIOS can be dangerous. If a BIOS update is necessary, what sorts of precautions should I take?

PC MightyMax 2009 was included with the purchase of my new HP a6827c with Windows Vista. After trying out MightyMax I decided I didn’t want it due to its obscene costs. I obtained the instructions for removal—go to the Start menu, go to the PC MightyMax folder, and hit the uninstall button, but the software does not fully uninstall. Help! —Shannon Swank
Doctor, I managed to get two computers infected with AntiVirus2009, simply by following a link to a video review online. Both machines run Windows XP Professional SP3. One is a Dell Vostro laptop, the other is a desktop I built about three years ago.
I’ve run Malwarebytes’ Anti-Malware, which removed a bunch of copies, Rogue Remover, SuperAntiSpyware, ThreatFire, and ZoneAlarm Internet Security, but every so often a new browser window will suddenly open and try to access AntiVirus2009.com. I’ve looked at every website on the Internet (well almost) and nothing I’ve tried will get rid of it on either computer. The only way I’ve been able to keep using the computers is to manually block antivirus200*.* in ZoneAlarm. Every time I check the log, there’s entry after entry where it tried to send an ICMP ping to that website or tried to open Firefox to access it. I’m at the end of my rope. I don’t know what else to do and I’m sure that there are other people out there having much the same problem as I am. Is my only hope to re-install Windows? —Steve Rugg

At first I thought it was a fluke, but when I first installed Win7 Beta on a new HDD on my laptop, one of my USB ports stopped working and performance of the others took a nosedive, with some USB devices not getting enough power. I tried a reinstall with Win7 RC and now three of my four USB ports are having the same issues. It may not even be an issue with Windows 7 but there seems to be a correlation that the problem started and got worse with each installation.
I have Windows 7 running on two other PCs with no issues and all I can find on the Internet are people with the same problems but no solutions. I’m sure you can imagine how much it sucks having to use a four-port USB hub just so I can connect more than one USB flash drive.
I have a home-built PC that uses a Gigabyte GA-EG45M-UD2H motherboard. When I load it with 8GB (four 2GB sticks) of RAM, I find that I cannot install either Windows XP or Vista 64-bit. The installation process fails partway through the “expanding files” section, with a “corrupt files” error. I tried new install media to no avail. Eventually, on a hunch, I removed all of the memory except the module in slot 1, leaving 2GB on the system, and the install completed normally.
I tested all of my modules in slot 1 and all passed. I then tested a module in each slot and all four passed. So what could be the issue with this motherboard? The memory (Kingston DDR2-800) is listed in the compatible memory list and the motherboard supports up to 16GB. I could find no information about this issue on Gigabyte’s website.
I was recently reviewing different graphics programs for showing video files when I noticed that Explorer now refuses to display a miniature version of video graphics files when I go to the thumbnail view. It still shows miniatures of picture files (.jpeg and .bmp) but not video files. What would cause this? Is it possible to fix it without reinstalling the OS (XP Pro)? The video files show the miniature version when exported to another computer, so there must be something different with my OS. I’ve tried everything I could think of but no luck.
I have a month-old computer with a 64GB Falcon SSD for my OS and my most frequently played games. After I first installed the OS and all my games I had roughly 13GB of free space. Everything I’ve downloaded and installed since then has gone on my secondary drive; I have not added anything new to the primary drive. Despite this, I now have just 137MB free on my primary drive and am getting warnings of low disk space. Where is my available space going? I did a disk clean-up and that hardly freed any space. I’m running 64-bit Vista SP1. Any help would be appreciated.
