I got a new custom gaming pc at Christmas which has worked all ok until around a week ago when it blue screened and came up with an error saying "MEMORY_MANAGEMENT" a few days after this my TP-LINK TL-WDN4800 wireless adapter stopped working, I made sure all drivers are up to date, uninstalled and re installed drivers after this I put an ethernet cable into my pc and that worked perfectly, but then something happened and it is saying limited connection and i can't fix it.



XFX R9 280x GPU

Gigabyte 990FXA-UD3 SKT-AM3+ Motherboard

TP-LINK TL WDN4800 wireless card

16GB Kingston HyperX Preditor RAM

1TB Seagate barracuda

Please help as pc is also needed for homework

Thank You in advance
