Big torrents stop at 99.9% or similar

Ok, so I've been having this problem a while but I've just circumnavigated it up until now since i couldnt fix it but im getting irate.

 

Smaller torrents up to say 800mb will download great and reach 100% check and complete perfectly,

 

however, when downloading larger torrents for some reason they never reach completion, and if they do, after the check they always go back to 99.7% etc and never actually stay at 100%

 

I've checked a lot of forums and people say it must be an incomplete torrent and just wait. i tried that and it happens far too often for that to be the problem as most torrents that i have this problem with are very popular torrents with lots of seeds.

 

Some torrents do work, but the larger the torrent the more common this problem is.

 

I really have no clue, I've tried downloading to different hard drives, I've used other software, changed firewall settings. 

 

Theres no problems with speed i get up to 7mB/s on some downloads 

 

I just checked a random torrent im downloading and it says wasted 1.63Gb, 183 hashfails.

 

I have no more ideas for cause or solution so if there's any ideas i would really appreciate them thanks!

 

p.s. some screengrabs showing avail. (taken at different times hence change in number) dont know if it helps:

High hashfails indicate either poisoning, or hardware/software failure in your wetup.

DLink router?

I'm using a virgin media super hub but connected with an ethernet cable.

 

I've ran avast free virus check it found nothing.

 

I do occasionally get BSOD with memory management. I mean I thought it had to do with my RAM but that could very well be related to the problem.

 

Thank you
