From what you've said it's probably either a hardware problem with your computer's wifi antenna or a software problem with the adapter. I'm not really knowledgeable enough to precisely diagnose it or offer specific advice.

What messages does it return when you run a network diagnostic?

Having a very odd problem in Windows 10. Downloaded files have a habit of refusing to copy with the error message "cannot read from source file or disk". A disk scan turns up no errors, and the files work perfectly - no skipping in video files, no missing/distorted text in text files, etc - as long as I leave them in the downloads file. This makes me doubt that it is a bad sector or similar problem. Is it possibly a permissions issue?

No, that would give you a permission denied error, and I doubt you'd be able to open the files in that case either.

Conflict with a virus scanner maybe?

My only virus scanner is the one built into Windows, so that sounds unlikely. I tried copying it via command prompt and got the far more helpful diagnosis of a cyclic redundancy check error, but I can't recall the last time a file with a legit CRC error was useable.

The files fail to copying in win7 as well.

I suggest you replace the disk then.

Ok. Funny story.

So i replaced my ram some time ago and wanted to insert the old ram into my fathers PC.
The Mobo has both DDR2 and DDR3 slots so i removed the 2 gig DDR2 and inserted the "new" ram inside the DDR3 slot.

And after turning on the PC... nothing. The PC is powered up and humms but the screen stays black so i can't even see the bios and i have no clue why.

What is the CPU/motherboard? It's possible the CPU has to support DDR3 and yours does not.

Phenom 2 i think. Basically the weakest thing you can put in an AM3+ socket.

OK, so I have this antique laptop that was given to me for free. Surprisingly, the battery still holds a (partial) charge.

The downside, apart from it being an antediluvian horror, is that it has a 10gb IDE hard disk inside. >.< 

I was able to install Linux Mint on it, using some clever combination  of putting a 64gb low profile USB thumdrive on and mounting that as /home, and using the 10gb IDE drive as /.  It runs "Ok", given what it is.

That said, I have decided that using the thumbdrive as /home is inelegant. I have instead decided to try something silly. So, I purchased these together from amazon (Delivery on the 4th, if you can believe their forecast.)

Item #1 (purchased before sold out, at very big discount!)
Item #2, also purchased at a nice after-holiday discount.

I notice that the first item supports SD card spec 3.0-- That means it can handle the full speed/capacity of SDXC cards, like item #2 is. :D

Not that it matters much, since the max you can get out of IDE interface is UDMA 133, which tops out at around 33mb/sec.

Come Monday, I intend to replace the 10gb drive with this combination of items. Given that this thing is rather lacking in the RAM department, I am going to make flagrant use of ZRAM, but are there any additional caveats I should be aware of when abusing flash media as if it were a spinny disk?

You might have been better off with compact flash instead of SD, as compact flash literally is a laptop IDE interface shrunk down, so the adapters were even cheaper last time I looked.

That said, with something that old you run the risk it doesn't support LBA, in which case you might need something that supports the old CHS addressing scheme, which was spinning-disk specific...
Edit: sorry misread as 10MB, it's not half as old as I thought.

Apart from latency, which should still be better than the old spinning disk, modern SD cards should be able to take some laptop level of use fairly well.

OK, I've looked it up, and all the CPUs for AM3 should support both DDR2 and 3. Maybe it needs a jumper changing? I'd look up the motherboard manual online.

I have some CF to IDE adapters, and they rarely support dma mode access, even if the cf card should be able to do it. I have a #2gb highspeed CF (well, for its age anyway. 40mb/sec rated sandisk) that was purpetually trapped in PIO4 mode. :(

The SDCard adapter specifically mentions it supports DMA access modes. 

Also, SDCards are waaaaaaaay cheaper than CF cards, and have bigger capacities.

Can anyone recommend a good downloadable OCR program that I could run PDF files through so that text can be selected and copied? Preferably one outputting a modified PDF rather than a file in a different format.

What I'm looking for is a downloadable open source or at least free version of this:
