I purchased a Rosewill keyboard about 1.5-2 years ago(This model: http://www.amazon.com/Rosewill-Mechanical-Keyboard-Cherry-RK-9000BR/dp/B005QW1THA/ref=cm_cr_pr_product_top). It's worked fine up until about a month ago. It started to disconnect and reconnect to my computer almost daily, it made the sound as if I was installing me software/hardware onto my computer. Last night it kept shutting off and turning back on, and this morning I went to sign in to my computer and I couldn't. The number,caps and scroll lock lights were all lite up, usually it would do that when it reset, then it would come back. I would usually have to mash keys and it would activate, I tried everything to no avail. Unplugged the keyboard, unplugged it from the computer, restarted my computer, re-installed drivers for it and nothing has seemed to work.
I even checked to see if my port area was destroyed because this is my 2nd keyboard from them, the first one i sent back within a month because the port somehow got pushed in(I never even moved the keyboard no idea).
If you have any solutions to this problem i'm all ears, considering i'm typing this on a $8 dollar dell dome keyboard that has a pound of dust and dirt on it, and I've sneezed at least 20 times just within typing this.
Thanks for any help, and input giving, happy gaming!!
