Sata 6 Mysteries

Ask the Doctor LogoAre 6Gb/s SATA ports on the newer motherboards backward compatible like USB 3.0 is with USB 2.0? I’m eventually going to purchase either an Asus Crosshair 4 Formula or a MSI 890FXA-GD70 motherboard.

I need to know if my two Seagate Barracuda 7200.12 1TB hard drives will work in these motherboards’ 6Gb/s SATA ports. I won’t be using any RAID configurations. The first drive is for Windows 7 64-bit and programs. The second is going to be for the Documents, Downloads, Music, Photos, and Videos folders.

Also, when are 6Gb/s SATA hard drives for desktop computers going to be available?

Dual BIOS Necessary?

Ask the Doctor LogoI am looking at a new build with an AMD CPU. I normally use Asus, but I see that Gigabyte puts out a board with a dual BIOS. What are the advantages and disadvantages of a dual-BIOS board?

Help Rock out My System!

Ask the Doctor LogoMy current rig is an HP Pavilion M8530F with a Viola-GL8E motherboard. The CPU is a 2.2GHz Phenom X4 9550. The board is AM2+. I asked HP for a copy of the mainboard’s user manual hoping it could tell me what AM2+ chip I could drop in. However, I find myself even more confused. I think a 2.6GHz Phenom 9950 X4 will work even though it is a 125-watt chip and my current 9550 is a 95-watt chip.

I’d rather not spend the money only to be proven dead wrong and be stuck having to borrow my fiancée’s Vaio laptop. It may be nice, but it’s not my desktop. So far, the only change made to my rig in the two years I’ve had it was the addition of a graphics card cooler, of the intake variety. I’ve done research and the more questions I have answered, the more confused I get. If I could, I’d just buy/build a new rig, but that’s not an option. Some newer games, like BioShock 2, require AMD core speed in excess of 2.2 GHz, and mine barely meets the requirements. Even the budget upgrade article in the July 2010 issue is vague on whether I can upgrade. Doc, please steer me in the right direction, lest I crash on the rocks of inaction.

Kill In-text Pop-ups

Ask the Doctor LogoRecently, a lot of websites have started to put little pop-up advertisements in their text. I read with my mouse, so as I follow along with my pointer I hit a word like “Film” and it pops up with a little box about local theaters. It interrupts what I am reading and is really annoying. Is there a way to turn this off? I know it’s an advertisement and a source of income but I get enough of that when I have to sit through a commercial to watch a movie trailer or get an ad page in between going to a new web page. I use Chrome as my main browser, and Firefox and IE when I have to.

A Sharper Image?

Ask the Doctor LogoI’ve been contemplating purchasing a 120Hz monitor for some time. After reading the May 2010 review of the Acer GD235HZ, this now looks like more of a possibility. I currently have a GeForce 275 GTX, and my understanding is that in order to take advantage of the 120Hz, I need to connect to the monitor with dual-link DVI. However, will this 120Hz monitor do for games what 120Hz has done for movies and TVs? Does it deliver that same crisp image that makes it feel like you are right there with the cast? Also, would a streaming service, such as Slingbox, have that same feeling if I’m steaming at HD speeds (2Mb/s+)?

Disappearing RAM

Ask the Doctor LogoI have two 1GB DIMMs of DDR/400 installed on an Intel D875PBZ mobo. The board has four slots, and I have the DIMMs arranged in dual-channel mode. I have double-checked it and I have one DIMM in channel A, slot 0 and one DIMM in channel B, slot 0. About once a week, every few restarts, the machine reboots with the error saying that the RAM amounts have changed. When I check, it shows each DIMM as 512MB instead of 1GB. On occasion, it will show the correct amount, but it will be in single-channel mode only! Keep in mind, I swapped in these 1GB DIMMs recently from a pair of 512MB DIMMs. I tried updating the BIOS but have had no success at all.

Mysterious Random Folders

Ask the Doctor LogoI have four hard drives I use for storage. One of my drives is a 1TB WD Caviar Green. A folder named “35c7b77f9e7bab635e2efb4b74b9” keeps appearing, with a file “MPMiniSigStub.exe” and a bunch of files with names like “1.81.790.0_to_1.81.799.0_mpasdlta.vdm._p.” When I delete the folder a new one with a similar randomly generated name appears in its place, with similar files in it. I scanned with Malwarebytes’ Anti-Malware, Norton 360 4.0, and Microsoft Security Essentials; none of them detected anything bad. I have also “hidden” the folder, but it reverts back to non-hidden status.

Migrating to Home Server

Ask the Doctor LogoI’ve been considering building a Windows Home Server. My problem is that I have three 1.5TB hard drives with media on them. Can I move these drives to a Windows Home Server machine without formatting them? They are currently formatted in NTFS on a Win 7 machine. I have everything for the home server except the case and power supply. I also have a 40GB hard drive that I had planned to install the Home Server software on. I don’t have the money to buy new drives to transfer the media from the other drives. Also, will I be able to stream .vob and Blu-ray files to Media Center on my other machines?

Next-Gen Wireless Worse than Last-Gen?

Ask the Doctor LogoI have a Netgear WNDR3300 dual-band router that broadcasts both 802.11g and 802.11n signals. Today, I noticed that in certain areas of my house, the 802.11g signal is actually stronger than my 802.11n signal, by a lot! Shouldn’t this be the other way around? Currently, the router sits atop a bookcase in my basement as I don’t have anywhere to put it upstairs. The signal comes from a cable modem and is attached to a Windows 7 Pro 64-bit computer. What gives?

What Happened to AutoRun?

Ask the Doctor LogoI am using Windows 7 Home Premium and I have found that there is no longer an AutoRun option that permits the automatic startup of USB flash drives that contain software. I am particularly referring to flash drives that contain portable operating systems such as Portable Apps or SanDisk U3 Launchpad. The user is now presented with a prompt that permits viewing the files and double-clicking the application to be executed.

Is there a registry hack that I can use to restore the AutoRun feature for USB flash drives that contain applications?
