Hi, I've been having this trouble for quite a while now.

I've been using my pc normally for the past years but now my keyboard is not working properly (the keys for 'a', 'z', 'q', '1', esc and TAB are not working), so I decided to buy a new keyborard, which for my surprise didn't work when I plugged it in, I tried pluggin it in nother computer and it worked just fine so it was not the keyboard. From then on it has been quite a ride trying to figure out what the problem is.

I tried pluggin keyboards from other computers, none have worked propperly (I have tried USB and PS2), but there's just one detail: SOMETIMES they work normally for a while and then they die, SOME OTHER TIMES if I have my old keyboard plugged in all the other keyboards that i plugg in will work but SOMETIMES they have input delay or just straight don't work, SOMETIMES they beep whenever I press a key and sometimes if I move them too much they just stop working.

nyways as you can see it's been kind of dificult to figure out what the problem is and I would like someone to help me out a bit. These are the specs of my system and keyboards:

PC:
Windows 7Ultimate SP1
Intel Core i5 3.10 GHz
8GB RAM

Old Keyboard (the one that works):
Generic Genius USB Keyboard

New keyboard (hardly ever works, only when I plug the old one as well and sometimes fails):
Generic USB Keyboard (no brand on this one)

Keyboard from another PC that I tried (works by itself sometimes but when it fails I get it to work by plugging in the old one):
Wash PS2 Keyboard
 
I will try that latter as rn I'm backing up my data so that I can format my hard drive and do a clean windows installation. I will update with results.

NOTE: a couple of minutes ago my pc started to continously beep every set amount of time, I had heard this beep before, sometimes when I pressed keys when the keyboards where not propperly working it beeped like that, it is not a mb beep since I cannor hear it when I turn off my speakers.
