So usb 3 can supply more power in terms of ma's than usb 2 but do they both use the same connection in the same position. For example if you plug a usb 2 device into a usb 3 port with a usb 3 cable will you get more power (available milliamps) available than you would if you plugged it into a...

If you wanted to uninstall Windows 10 from a computer and use another os but still have the option to reinstall windows 10 at a later date, what do you need to do before uninstalling to retrieve the cd key etc. (where the windows 10 install was an upgraded windows 7 retail). What's the simplest way?

I am trying to get a fan to upgrade a fanless pc that overheats in summer by adding a fan. I found this picture of the motherboard, does anyone know what this 4 pin cpu fan plug type is called?

I have a small fanless computer that overheats in summer without an external usb fan but if you connect a usb fan it will stay on in sleep mode and even when the computer is off. There is no way to change it in the bios. Is there a way to connect a very small fan to any other wires on the usb...

I have an mce remote but unlike moving the mouse when you press a button it won't turn off the screensaver. Does anyone know if there is a way to get the remote to turn off the screensaver. I've got it going through eventghost and autohotkey, so I'm not sure if that is making any difference to...

I want to know if anyone is successfully using a usb 3.0 flash drive through any length of extension cable. I have had no end of trouble trying to use extension cables or hubs. I want to know if it's just inferior quality cables etc. or it's not supposed to work. I even tried a very short...

Can you add a usb flash stick to a computer as storage (instead of a hdd/ssd) and leave it connected all the time with no issues like loosing data over time?

If you join two sata power cables to make a double length cable to ssd/hdd, could this be too long for the gauge of wire used in standard cables? I'm not talking about the data cable, just the power one from the psu. Since usb external drives never seem to work with longer usb cables maybe...

Hello, I am trying to print labels that have to match exactly to measurements on the page, but the basic laser printer I have is a bit off and prints lines a bit leaning over and misaligned. I tried to adjust it but can't get it to be any better. What type of laser printer (or other type but...

Can anyone suggest a super mini computer to run linux to watch videos at 720p (having 1080p ability wouldn't be bad either) from a usb stick. The only other requirement is that it has to be able to run gamma adjustment commands such as "xgamma -bgamma 2.0 -rgamma 0.5" for example. and this...

Does anyone know if I power a very low power usb device (ie. like a led desk light) from a computer while the computer is off (for many hours everyday) will it be less power efficient than powering the same device from a wall wort? Or are there any other downsides like wearing out the psu?

I have a good MCE remote control that came with a tv/video capture card. The receiver it came with though has a special 2.5mm type plug that only connects to the card it came with. Is there a cheap adapter I could buy or can I resolder the wires to a usb plug to use it with a usb port?

I have two IR remote controls and receivers but the receiver for the most important pc has broken (it's generating gibberish) so I tried to connect the other receiver instead but it will only work with the remote it came with. The other remote control was specifically set up for that pc, is...

Is there a cheap way that I can connect a keyboard and mouse to two different computers. I would never be using both computers at the same time, I know there are kv switches but I thought something more like a hub with two pc connections. because I don't need to use both at the same time. Any...

I have a main monitor (with a normal short cable) but I also want to connect a second monitor to duplicate the display so a second person can view the screen. I am trying to use a 5m hdmi or dvi cable for the second display and both cables fail (the hdmi one works at first sometimes, then cuts...

My windows 7 colour calibration is wrong somehow. Blacks look grey, everything looks very washed out. With linux there is no problem. I have used f.lux (but uninstalled now) and also run an eye one colour calibration (which I have uninstalled now) in the past (with old monitor). How can I...

I have Windows 7 retail now which I believe I can continue using if I buy a new motherboard and cpu in the future. But if I upgrade to windows 10 will I forfeit this retail right and I'll end up with just an oem version that I have to throw away if I upgrade my motherboard/cpu in the future? Or...

I have Windows Vista installed on a computer but it often comes on in the middle of the night. Ie. 2:30am last night. It is set up as a pvr but frequently comes on with nothing to record and always in the middle of the night. Often it stays on all night even though it didn't record anything...

I just bought a kindle touch 6" and opened it but I think I have made a big mistake. I bought it because it was the only ereader at a local shop but I didn't realise I couldn't use it without wifi or an Amazon account. Is there a way to use it without one by reflashing it? I just want to read...

It's been for a while that I couldn't install silverlight 64 bit (the default version it downloads for my 64bit windows vista) but I could install the 32bit version that worked enough to use. Yesterday there was a windows update which was automatically installed and now silverlight no longer...

I am having a problem with my mini pc. When you start the computer, every so often at least one usb device fails to work (the device is powered but the computer fails to detect the device). It is fixed by either restarting the computer or unplugging the device that didn't come on and plugging...

Has anyone else noticed Firefox crashing recently, ie. since the last update? I'm just trying to work out if it is a problem with my system or a bug in this version.

I have a bedroom projector, with lots of clothes, blankets etc. And I just had to open it up and try to clean the lenses with a felt pad on a stick because it had accumulated a lot of dust that was starting at to look a bit like dead pixels. But there is a lot of dust in that room, is there...

I have a USB hub where some devices connected to it don't come back on after the computer wakes up from sleep, it is an intermittent problem that occurs at some times with some devices (possible related to how many devices are plugged in and to which ports. Until I updated windows 8 to 8.1 it...

Hello, I have a mini arm computer that I run android on, but I want to be able to adjust the display brightness for hdmi out. I have found (it is a known issue) that the brightness control in android doesn't work because it is designed to control built in mobile phone screens. Is there an app...
