BSOD while waking up from sleep

[Blargleflakes]

Hello,

I have recently built a new computer. For the most part it seems to work fine except when I attempt to put the computer to sleep and try to wake it up. Sometimes it wakes up fine, other times it simply black screens with hybrid sleep active. When I try to sleep with hybrid sleep disabled, I sometimes get blue screens (as attached below, though both are different). I had avast anti-virus installed when I got those blue screens and replaced it with Microsoft security essentials, since I have heard that avast sometimes causes blue screens. I am unsure if that solved my issue and would like to know if there are any other potential issues that may cause blue screens from waking up?

You did the right thing - the Avast filter driver was the cause of the BSOD. Keep MSE installed (it has never been found to cause a BSOD) and monitor your system for further BSOD's over the next few days, and report back.
