Anybody think they can help me out here? GRAPHICS CARD RELATED

Ok I just got myself a new computer. I have a new video card and everything. Generally it lags sometimes and we originally figured it was thr drivers for my graphics card. Which is an MSI EFORCE GTX 960. I have a monitor one hooked with an HDMI the other is hooked up with a DVI cable.

Now most of the time it’s ok. But when I do something like launch a big program like 3Dsmax or Z-brush or make a big transfer of files from my removable drive. It lags. I can move the mouse just fine but when I drag or close windows it lags.

My father and I have been trying to figure this crap out all day. And just to be clear It’s not malware related because to be sure I scanned and everything is fine. It just lags really bad when I do big stuff.

Anyone had this issue before? can you help me out? If so PM me please. Or if you just have some advice it’s welcomed.

Thanks guys.
