P.S. I posted this before and you guys told me to update my video driver and tablet driver. I updated my video driver but when i tried to right click on my wacom tablet driver and update it, it said it was up to date.

Could this be a hardware issue?

I will check the memory. I don't have the tablet pluged in! I almost never have it pluged in. Does it mean anything that google chrome keeps crashing?

Okay, i just did the Memtest86 and after two passes, there were no errors to be found. So if this isn't a memory issue, what kind of issue could it be?

Probably caused by : dxgmms1.sys ( dxgmms1!VidSchiProcessIsrVSync+64 )

A couple of thoughts...

Run memtest86+ to check memory.

Unplug wacom tablet, and all other usb devices, except mouse and keyboard. I am a little suspicious of USB problems.

Let's try this first and see how it goes.

I ran memtest86 twice and they found no errors. As for the wacom tablet, i do not use it at all. The main things i use is my logitech mouse, a western digital external HD and a segate exteral HD.

Could this has something to do with the motherboard or something?

I ran the test again except this time i let it do 10 cycles. Also, i am doing these tests with NOTHING plugged into my computer except for a flash drive containing the memtest86+ on it.

So what should i do next?
