Driver help

Hey guy's

I played my first round of the year two weeks ago, and my driving was terrible. I kept hooking the ball with my driver, my iron play was not to bad. I usually shoot around 85-90 on par 72 courses sometimes higher on bad days . Ive been playing golf for about 6 years but usually only play 15-20 rounds a year, I only have 1 playing partner and he can't always play, I love golf so, this summer I'm going to try and get out and play more which means going to the course as a single.

For the last 6 years I've been using the baseball grip. Today I went to the range, wanting to practice my driving with some iron work. Instead of the baseball grip today I used the interlock grip, tried the vardon also but didn't like the feel. I hit some good drives along with good irons but take 10 shots maybe 6 were good ones. My driver had long distance but a huge slice. My irons were straight most of the time, but I had the odd ball that would go 15 feet, or sometimes they would leak right, I was taking nice divots with the shots the ones I didn't I would skull.

Here two videos of my swing hopefully you guys can give me a few pointers.

Thanks for any help
