Hey guys, so my old computer finally gave out and I built a new pc. Sometimes when I'm working on the computer my monitor will go into sleep mode and the computer becomes unresponsive. I'll move the mouse or press keys on the keyboard and it won't wake from sleep. If I reset the computer then the problem goes away. Also sometimes my cursor just stops working and freezes and when I try to press ctrl+alt+del on the keyboard nothing happens but when it does start to work again, it's extremely laggy.
It's about a week old, the only things I have installed on the computer is adobe cs6, firefox, trend micro, malwarebytes, blackberry desktop software and itunes. I recently installed flash player plugin because I needed it for my online classes. OS and programs are installed on the SSD and pictures, music etc are on the HDD
The parts I bought from memory express:
Intel i7-4770 3.40GHz
Asus Z87-A Mobo LGA 1150
Patriot 16GB Viper 3 1600MHz C10 kit
Corsair Force LS series 120GB SSD
Seagate 2TB Barracuda 7200RPM
Cooler Master CM690-II Advanced Case
2x Bitfenix 120 mm Spectre Fan
120mm Cooler master cooling fan
Bytecc Card reader
Win 7 Pro SP1 64bit
Parts I reused from my old computer
OCZ 650 watt psu
Geforce gtx550 ti
I'm not very good with computers so I don't know where to begin to look for possible causes. Thanks again
