I have an Asus Q87M-E, in the BIOS (ADVANCED MODE) in the Advanced tab\ System Agent Configuration\ NB PCIe Configuration, there's an option "PEG - ASPM". It's set to auto by default but has the option to go to disabled, ASPM LOs, ASPM L1 and ASPM LOsL1. What does each option mean?

Here's what google says: 

Active-state power management (ASPM) is a power management mechanism for PCI Express devices to garner power savings while otherwise in a fully active state. Predominantly, this is achieved through active-state link power management; i.e., the PCI Express serial link is powered down when there is no traffic across it.

L0 – All PCI Express transactions and other operations are enabled.
L0s – A low resume latency, energy saving “standby” state.
L1 – Higher latency, lower power “standby” state (optional).
L0sL1 - Activate both L0s and L1 support.

Everyone was a noob at the beginning, don't be discouraged by toxic trolls even if u lose 15 times in a row. Keep training and pushing yourself further and further, so u can show those sorry lots how it's done !

Be a supportive player, and make sure to reflect a good image of the game community you are a part of. 

Don't kick a player unless they willingly want to ruin your experience.

We are the gamer community, we should take care of each other !
