I have had my meter for years and most of the time I have no problem with my strips: as long as I get enough blood on the strips and my meter is warm enough, I get results. They may not be the results I want, but my meter tells me my BG.
However, a few years ago, my meter and I had a falling out: many many of my strips reported an error. I tried a new packet of strips and the same happened. I tried the closest I could think of in terms of switching it on and off: taking the batteries out and putting them back in: and it still didn't seem to like the strips.
Finally, I changed the batteries in my meter. After days of cursing the strips, I realised it was just a power problem in my meter and we have been friends ever since ... as long as I remember to change the batteries.
Your situation may not be the same but, from my experience and frustration, I would recommend giving it a go if it is possible.
If that doesn't work, try a new batch of test strips.
If that doesn't work, most meters come with a warranty (if you remember to return the registration card) and the manufacturers are pretty good at replacing them if they are faulty.
