I make my students submit their assignments (for college writing classes) by uploading them as PDFs to our course management system. Sometimes students submit broken or un-openable files. My question is, how do I tell the difference between a real PDF file that became corrupted somewhere along the line and a fake corrupted PDF file created by a student who didn't do the assignment and wants an excuse?

I have a laptop (Toshiba A105 S4344) with a windows xp install and a bootable USB clip with Win7 on it. I want to put Windows 7 on the laptop. If I take the hard drive out then the USB clip boots fine (but has no hard drive to install windows on). If I put the hard drive in then it runs windows off the HD even though USB boot is ahead of it in the BIOS startup order (and when I put a blank hard drive in then it complained it couldn't find the windows startup files). And when I try and insert the HD after loading Win7 off the USB, the installer can't see the hard drive. I've checked the BIOS and there aren't any secure boot/UEFI shenanigans going on. I will probably end up burning the win7 install onto a dvd, but does anyone know why the Toshiba would be overriding the boot order?
We have a several Macs at home. We want to securely connect to any of them from outside of home, via other Macs or iPhone or iPad and pull off files or use the home computer via the remote Mac/iDevice if needed. Talk to us like we're not tech savy and tell us how to do this. All the macs are running 10.9.2.

Yet another laptop question. I only need a laptop for surfing the web, downloading, watching DVDs and streaming Netflix for around $500. Unfortunately, I don't know much about laptops. I do know that I want a terabyte hard drive and I don't care about touch screen. I found this and this both from Toshiba, both very similar. Will I be happy with either of them? Will Windows 8.1 piss me off? I am also open to other suggestions.

About six months ago we started having issues with our computer monitor. Upon booting our 2-ish-year-old Dell desktop, the monitor would blink on and off a couple of times, then work as normal. As time went on, the blinking went on longer and longer until it was doing it for close to a half-hour. [more inside]
I have a dull, constant pain mostly around my elbows and forearms.

How can I mitigate or prevent this pain without drastically altering my lifestyle? I understand you are not my doctor. [more inside]

Tomorrow I'm hosting a presentation where the speaker would like to hook up a laptop to two decent-sized external speakers. All that's lacking is a cable. I'm hoping to run out to the electronics store tomorrow morning to buy a cable (or two?) to do this, but am completely baffled as to what to get. I plan to call the store in the morning, but simply because I am nervous about the presentation and would like to sleep peacefully tonight, can anyone here recommend exactly what kind of cables I should get?

I bought a new Dell XPS 8700 last fall. Lately, the damn thing seems to work like an alarm clock ALMOST every night around three or four am. I wake up to hear three rapid beeps over and over. This lasts for about a minute. This happens even when I shut it down. [more inside]

I'm in grad school. My friend/classmate accidentally knocked over her water bottle on Wednesday and drenched my MacBook Air (which was on the classroom table about three feet away), killing at least the motherboard (per the repair shop where I took it) and possibly other things as well. It will cost at least $520 to repair; I'm out of AppleCare coverage because I got my computer a bit over a year ago. I have two questions. [more inside]

I need a laptop for travel for about 3-4 weeks a year, and up to this point I have always had an old one I can tote around, I recently bought a series of older macbooks through craigslist that did the job for a little while, but both, for various reasons are no longer working and can't be fixed without a lot of cost. I am hesitant to try for another craiglist computer, because of my recent experiences, but I also don't want to lay out the money for a new macbook because of how infrequently it will be used, it just seems, well, wasteful both monetarily and also letting a new computer collect dust. It needs to be able to run Adobe CS 5 or 6, it can either be a mac or pc, though ideally a mac. If no other options present themselves, I would most likely look at Apple refurbished. But are there any other sources that I am overlooking?
I have to stare at this thing an awful lot for work, and of course I stare at it recreationally too. But after a few hours a horrible dazed feeling creeps up on me.

I have somehow gotten the search engine highjacker "searchya" on my computer and have followed all the instructions I can find on-line to get rid of it but it still shows up as the default search engine.

Thanks MeFites for your assistance; now for a Mac Mini question! The Flashdrake is needs a new computer to take to Italy for around 5 months a year; he currently uses an all-in-one desktop PC in Australia running Windows 7 and a 23" screen. Has been using a 17" 2010 laptop now running Windows 8 when travelling to Italy, although doesn't like using it, finds the screen hard to see, and never got a handle on Win8. I could buy a new laptop, or a new desktop to keep overseas, but it seems that getting a Mac Mini and hitching it up to a monitor at either end. While we would still backup, it seems like an elegant solution. He is not familiar with the iOS, but loves his iPad, which he uses when he needs portability when out and about. Is there something that I'm missing here? I imagine that as long as we avoid an expensive Apple monitor (that's possible, right?) it would work well, with be relatively cost effective. Thoughts? What am I missing here?

My Data Traveller has become inaccessible showing up only in my devices and printers window as 2261 Pram, a new term for me. Placing the memory stick in other USB ports not helping and location G:\ seems impenetrable and unchain able as does everything on my storage device.

I maintain a PC for a user who has dementia and who breaks the computer in short order. So I installed DeepFreeze (thanks AskMe) and it has worked great, but now they turn off the computer without shutdown so it eventually blue screens and won't boot at all. What can I do to make the system impervious to turning off without shutdown? I'd like to stay with Windows if possible for a number of unrelated reasons, though open to Linux if there is no other option assuming it can be "frozen" cfg and remote management.
I posted a question here about this last year, but since then my old laptop went belly-up and now I need to find a good replacement in kind of a hurry.

My dad passed away on Friday, and my mom is eager to get into his computer (Song Vaio running Windows 7) and Blackberry (Bold). Both are password protected.

We also have access to his email if that helps with the Blackberry. Thanks.

Hi, I have 1 keyboard, 1 mouse, and two desktop computers to use with a 3-monitor setup. I would like to know the best way to use a triple monitor setup where I can click a button and switch back and forth between desktop A and desktop B for the single keyboard/mouse and the monitors. Consolidating files onto one machine is not an option. Are there devices or hubs I could plug the keyboard/mouse/monitors and desktops into that can do this? Amazon links would be great.
I live in an EU country and will be visiting the States soon. I also need a new laptop (I'm a Mac user). Given the favorable exchange rate, does it make sense to buy it while I'm there? What kind of hardware or other issues will I face (charger, keyboard, etc.), and is it worth the hassle?
My Dad often has trouble with the computer that run along the lines of "can't download email attachment" or "doesn't know how to forward email". I need a program that will allow me to access his computer remotely so I can do simple common tasks for him, as he's unable to retain the information even when we go through it step-by-step, over long drawn out phone calls. Being able to see what's on his screen, or to indicate to him where to click would simplify things for both of us greatly. I have used RealVNC before, but only within a home network and don't know how challenging it is to do over the internet. We are both using Windows 7. Thanks.

So, I have a PC. It was custom built by some guy but is nothing special. Runs XP, has a hard drive, etc. Earlier today I used it for 2-3 hours and then shut it down. It emitted a serious melting plastic smell that stunk up half the house, and it froze on the shutdown screen--the mouse would not move. I freaked out and unplugged it. There was no smoke or anything visible, and there were no sounds of any sort. I opened it up and nothing looks amiss. I started it up just now and it works fine. No smells, all the fans work fine. I'm actually using it to post this question. Any idea what could have happened? I'm 99% sure it was the computer emitting the smell--it was definitely localized right there.

This morning I was working on my computer, and stopped to take a break for lunch. I left my computer on--it generally goes to sleep after 10 minutes of inactivity. When I returned from lunch, my computer had unexpectedly shut down and had to be rebooted. Once it restarted, I noticed that it had updated several programs that have been prompting me for updates, like iTunes and Firefox. (I had purposefully not been updating them.) My computer requires permission from me to update programs like this, and it has never updated programs without that permission. Any thoughts as to what might have happened this time? [more inside]

Hi, We just got an Ipod Nano (the latest one) for Christmas and when we first got it out of the box we were able to download music from our computer to the I-Pod. We did it with I-tunes and I remember seeing something that indicated that the I-Pod was being recognized by the I-tunes website. No problems downloading to the I-Pod. But now I'm trying to add some music and the I-Pod is not being recognized. The new songs are in my library (under I-tunes) and they are already paid for. I have Windows Vista. The little white USB cord is not having a problem with charging the I-Pod, but nothing on the computer indicates that the I-Pod is recognized. When I am in the library, I click on DEVICES, and I can see a word that says sync, but sync is not in bold, another words I can't click on it. Any advice? I already turned my computer off and on again, and also took out the USB and put it back in as well. I went to the website and read the manual but there is so much there and I don't see how to do any of the instructions if the I-pod is not recognized. Thanks, Lynnie-the-pooh

I like playing around with text recognition algorithms, but am stymied by a lack of a good corpus to train and test my code against. I'm looking for a large number of images of individual printed letters, labelled with the correct letter. (With the letter in the file name, or each set of letters in a directory, or something equivalent like a metadata file.) Something like this, but more of it.
