Toshiba Satellite A505 S6980.

Windows 7 was starting to have issues. It would hesitate/hang when I went to type something, open a browser window, right-clicking, selecting an email in Thunderbird, etc.

Task manager showed the disk going from 5% to 100% all the time, up and down, within the span of 10 seconds. Also, it was taking forever to start up.

Things I've tried in order to fix it:
1. Upgraded to Windows 8.1.
2. Ran chkdsk and other hard drive tools. All results good.
3. Ran memory tests and reseated the memory. Nothing bad reported, all RAM utilized.
4. Updated BIOS from 1.6 to 1.8.
5. Defrag via Windows AND Defraggler.
6. Deleted paging file, changed virtual memory allotments, allowed Windows to manage virtual memory.
7. Many other things I can't even remember from many forum posts.

The only thing I can think of is that I chose to keep my files when upgrading to
8.1, causing me to keep a bad driver...? But I've uninstalled most drivers and re-downloaded/reinstalled from Toshiba's website.

It's not horrible, but mostly just frustrating. Typing something one second, waiting the next second... Oh- and the cursor is blinking while the text is still not completing. Never seen that one before.

Any ideas?

I'd back up your important files, if possible, and do a clean install. Migrations from 7 to 8 without installing in a CLEAN fashion often tend to result in problematic behavior carrying over from the previous installation.

Does the problem occur when running on both battery and AC power sources?

Have you tried using only one memory module or the other, despite passing memory tests? In a high number of cases, systems that passed Memtest testing still ended up having memory related issues that were resolved by replacing a faulty module or not using a memory slot that was presenting issues since the issue could be related to a bad DIMM slot on the board and not the memory itself.

There could also be an issue with a faulty boot partition...

There could also be an issue with a faulty boot partition table. I'd try the clean install first, making certain to follow the instructions exactly and delete all existing partitions on the target drive then installing to the unallocated space (Don't format prior to clicking install, Windows will create the necessary boot and system partitions automatically) and go from there.
