Alienware m17x r3 DPC Latency issue

Hey guys!!

My laptop has a bad Latency issue! I have a 580m, installed new Nvidia drivers recently, and have been playing tons of games.

My first issue, is that I cant go into sleep mode without the computer screen going black and the fans going on full Blast for a minute or so before it shuts off. Then when I try to boot out of sleep mode, the keyboard turns on, and the fans go on high again. It then every once in a while comes on, but mostly it just sits there with black screen until I turn it off.

It works okay with Hibernate, but even that is starting to go downhill.

I also have another issue. DPC Latency. It just started happening, recently, and it seems to keep getting worse. I often have more than 1600 microseconds of latency, people often lose sync with audio in the videos I watch, and when I am multitasking heavily, sometimes the audio completely stutters for up to 30 seconds, and the entire screen freezes too. I have blue screened about 10 to 15 times in the past year and a half, and it seems to happen once a month. I have a second gen i7, Bigfoot Network card, Samsung SSD and secondary 750 GB HDD, 16 GB of Ram, nVidia 580M, and Diamond thermal paste on the gpu and cpu.

How can I fix this? I have seen fixes on the internet for the latency but it wont let me install the stuff, saying that it is not compatible with my system.

Please help me before this thing gets completely destroyed. Also, should I invest in getting another year of Accidental protection?
