TS1567 My iPhone 4s connects briefly to my computer, then instantly disconnects. Has happened ever since downloading the ios7 update.

Question

I use a HP Compaq Presario laptop, and have done so for about 7 years. I downloaded the io7 update for my iPhone 4s 3 weeks ago, and now when I try to connect the phone to my laptop via the cable, it connects briefly but disconnects. I have installed the latest updates, both for iTunes and my iPhone 4s; I've tried uninstalling and reinstalling iTunes; I've stopped and resumed the Mobile Device Driver, and I don't know how to resolve the problem. I have recordings of uni lectures that I'd like to put onto iTunes, as well as videos that are too big to email to myself. Can anyone please help me?

I don't know exactly what you mean. If you mean when I got the phone, yes it was set up as a new one with nothing on. If you mean when I updated it, no- it had everything on when it was updating. The backup had actually stopped backing up at that point, i think, because of icloud running out of memory (despite it still having 1.7 gb left that I could backup info to). If you mean whether I have tried that, no. Many things that I need are backed up to the iCloud and many more aren't, and I am currently in the process of getting rid of things so it can do another backup, but with 2000 odd photos to sort through, it takes time, Music takes up loads of memory, but I don't know how to delete songs. I also have apps with data that doesn't get backed up or anything, so I would lose that. I can't really do the math, but today I got a thing saying that it hadn't been backed up in 6 weeks, so I don't know if the last backup was before or after iOS 8.
I am unsure whether i'll give it a try because even if it is hardware related, I won't be able to afford a new/second-hand phone or a repair for it for a while. Especially since it's out of warranty by a load if I am right. And even when I could afford it, I would be looking at upgrading to a newer iPhone because of iOS 8 being the last and stuff like that.
I don't know if this has any relevance, but I have also been having Wi-Fi and battery issues. The Wi-Fi issue being where it'll just disconnect by itself for a few seconds, and then return back, or sometimes I have to go through to settings and then Wi-Fi, and it'll realize there is internet and then connect to it, without me having to press anything. The battery issue being where it dies before it says it reaches at least 10% (once it died at 30%, most of the time it would be around 20% though) or it says it has 1% left but it lasts over 20 minutes still. As said already, I don't know if these have any relevance.
