My power settings is set to turn off display after 5mins. Occasionally my PC can't seem to wake up from this. The monitor is just black with its led indicator blinking. The keyboard and mouse's lights are on but the Caps Lock's led indicator is not working. It appears to have hangged. This happens once in a while.
Other issues that might be related:
- Occasional BSOD
- Firefox crashes once in a while too
Any ideas what could be causing this?
