Last week my computer was infected my malware,had a BSOD and wouldn't even boot. Luckily I got help on this forum removing the malware but I got a new problem afterwards.
Occasionally I cannot maximize programs from the task bar, they show up as (not responding) in the task manager and I have to use 'Switch to' by right clicking the program in task manager to restore it.
The program works fine until alt-tab or switch to another program/window. This happens with full screen games mostly but also sometimes occurs with notepad and even windows explorer.
It gets really annoying when it happens to task manager itself.
