My PC : There is no option ! Origin's website:

I have an old ereader (a Nook) that I've used for reading ePub books for ages. I mainly side-load books. I just plug it into a USB port and it appears as a folder, where I can add and delete things as I please. Until now. When I plug it into a port on my new laptop, it is not recognized...

If I have on my PC let's say sound on 50% and I increase it on 100%, how would the sound intensity change? Would it be twice bigger? But I think that function of sound intensity level dependent on sound percets is a linear function, isn't it? How to explain it? Why is it the linear function?

I'm looking for a database of binary stars within 10 PC of Earth, including information such as eccentricity of orbits, their distance from one another, etc. I'm hoping to find a list with this information, or just a collection of pages with this information. I've tried Simbad but I can't find...

Hello. Would you please explain the factors that determines the opening time of a program or a big file. For example if you have a large excel file, why would you have a difficulty to open it, if it is very large? If it is in your PC's main storage, that is either HDD or SDD, is it reading...

Hi all, I would like to back up my Android's downloads, screenshots to my Win10PC. Unfortunately, when I connect the PC to the phone using the charger, the PC does not recognize it, so that's not an option. I can send myself an email from the phone to my PC , but then I have to attach some 500...

Many, many wonderful ideas in that game. What sticks out most immediately is how a society which needs to deal with an infestation of large, occasionally hostile autonomous machines whose only common weakness is an inability to fly will "naturally" develop "structural engineering" that resembles...

Yes, this is a question. I already converted an old PC power supply (350 Watt) to replace the bower bricks for my Internet modem and router. What I would like to do now is install a 2-3 hour mini-UPS in the mix so I can remove it from my computer's UPS. I have spent days online scouring the web...

When we overclock CPU or GPU or RAM we also have to increase the voltage to achieve stable operation (provided we have adequate cooling). Why is that?

my system beeps 5 time, means CMOS is failing?

Our Windows 7 32-bit desktop PC is fitted with an Asus P7H55-M LX motherboard. It was working fine till yesterday evening, but from this morning, it won't turn on. (By this, I mean that it is not even starting the boot; the fan on the processor won't run.) My first guess was the PSU. So I...

My view of tablets and phones is that they are "companion" devices and are not a suitable replacement of a computer. They are there to help you perform certain tasks which you would previously have had to use a computer for and are generally very good at it but are still limited. They are there...

Frequent visitors of this forum will remember my previous thread where I mentioned an issue with the USB LAN adapter in our desktop - it used to disconnect automatically from the net. We could narrow down to the fact that the problem occurred only when we were downloading large files (>= 800...

Is a PC free from viruses when disconnected with internet?

I'm trying to have an in depth look and compare and contrast the various ways someone could get their PC games since it isn't always possible to get PC games physically and nowadays even if you do there are some caveats due to increasing sizes of games. At the same time I'm a bit of an old timer...

procrastination might be a bad term, but whenever I try to do some computational homework or any kind of productive computer usage, I find myself hours later just browsing some random stuff or binging youtube. It's always tempting especially when working on a browser to just open a tab and...

Hi PF! I'm about to buy a new laptop, and am leaning towards a 15". I currently use a macbook pro 2013 for my main computer, though I also have a PC rebooted for Ubuntu (it's my lab's, not mine). The new macbooks are very expensive, but very durable. To me, they feel very secure and well...

Summary: I want to basically multipartition my pc and use MY android OS copied from my phone as the dual boot OS. Hi all, it's been awhile since I've posted. Sorry for AWOL. What I want to do: Partition my hard drive and run my exact copy of android on the other partition. Why: I want to...

I was reading online that Connectify can be used to convert any desktop or laptop PC into a hotspot. Our PC is fitted with Windows 7 Pro, 32-bit. It doesn't have an inbuilt WiFi adapter, and connects to the Internet using Ethernet. I wanted to make a hotspot using this desktop. There are...

The SMPS in our PC went out a few months back. I confirmed that the device was not working by shorting the green and anyone black wires on the 24-pin motherboard connector. This was doubly confirmed by the mechanic who came to install a new SMPS. I was checking online for procedures to detect...

Hi All, I am having what seems to be power-related problems on my Win10 PC. I have looked into Device Manager, I ran DxDiag, checked into Msinfo32 and diagnostics say everything is fine. Problem is light on f12 key turns off and computer powers off despite receiving power ( you can see the...

Thanks to anyone who likes to chime in and help out this newbie. :smile: I bought some CC CV buck converters to power my DIY LED panel project using a perfectly working PC power supply unit that was collecting dust inside a fairly old and unused PC but unfortunately the buck converter does not...

Hello I'm trying to set up my gaming computer in my 2018 Kenworth T680 but having power issues. Both with the monitor and the tower. But mostly the monitor. I realize the power inverter is likely incompatible with monitor and tower PSU. I need a workaround. Issue: Monitor works interminitly for...

I would like to turn on and off 100 external (non screen) LEDs through my PC. I was thinking to assign each pin on my serial port an LED, because apparently you can control the power on serial port pins if I understand correctly. The problem is that even if I do control each pin on a port, what...

Hello PF, I am considering some options in my upcoming PC build and want to choose the one that performed best in MATLAB. What I mostly do is velocimetry with a big amount of points, image processing, statistical analysis. My options are between 2 CPUs: AMD Ryzen 2700 - for the 8 physical...

Hello, I just got a TV for the first time in about a decade, so I'm unfamiliar with TV's that hook up to computers, but this is the only way I'll be able to watch anything on this TV. The first is a picture of the connections I have on the back of the TV. The second one is the connections I have...

I have a PC at my home with Windows 7, 32-bit. It is used by my father and me, on the administrator account, which is the only user in the computer. Since a few months, while clearing the contents of the "temp" folder (accessed by %temp% from Run option in start), I am finding that several...

Hi All, I have this cracked electronic screen. Any suggestions, please?

I've been intrigued by this statement for a number of years. Certainly there is still a need for laptops, but there are undeniable trends and mobile tech is getting better every year. I see the next generation almost entirely on mobile devices. Perhaps PCs won't go away but rather become special...

Hi, I am just clueless about this. I turned my computer off with the battery at 100% ( I was using power cord with outlet). I disconnected from the server at the coffee shop, went to " Shut Down" on Windows icon menu, turned machne off. This morning I turn my PC on and the battery is at around...

Hi All, Just curious: every time I connect , go online, my PC automatically loads all the tabs from my previous internet session. Why is it doing this? Thanks.

I have installed an antivirus. But one day I realized that somebody was controlling my PC. Then I installed a firewall. There are lots of attempts to my PC which are recoreded in the firewall. I am very confused why these are happening and who they are, how they can do this. Now some important...

How can some PC scammers change the properties of a pc and its device manager to sell it to a high price? How can show another PC's device manager as that of the another PC? Thank you.

A few days ago my AVG antivirus detected a virus and successfully eliminated it. Since then I've been having an issue where a window will briefly popup but is immediately closed. I'm concerned that the virus wasn't cleared fully or that I've gotten another virus, but I've done several full scans...

Hi, I have a 350 w PSU (PC) with 3.3, 5 and 12 v outputs. I want to create a dummy load so that i will remain on and output the correct voltage. However, i found online that a 10 ohm 10w resistor is needed such as this one ...

I build my own computers. I've built and serviced many for others. There are some things I think are useful. - Always research. Don't automatically do something that someone says. Always research it thoroughly. There are almost always others who have had the same questions and often there are...

It's been years I don't have a desktop pc and now is the time I "need" one. My use will be numerical simulations, compiling general programs as well as latex documents, some lightweight/middleweight programming, using a virtual machine and use another OS's this way. I'll be using Linux only. My...

Perhaps this is the place to put this? I'm in the market for a new pc, and am thinking of doing it myself (this will be my first time building one from scratch). I'm fairly familiar with the components and what they do, but specifically, what I will need, that is where my real question lies...

Hello, What is the fastest connection method (i.e. type of cabling) to transfer images from a video camera to a computer, i.e. what type of connection gives the highest frame per minutes? Is a USB connection fast? If not, why not? Should I look at a camera that connects in a different way...

Hi all, It has been my nerd dream to have many screens to be able to see the same PC (Win 8.1)output in more than one screen. Other than the obvious way of having the same input in many PCs simultaneously, is there some other way of doing this, while having the option of doing basic functions on...
