I've reinstalled the drivers that a program called DriverCure suggested were faulty and cleaned up my registry, but that doesn't stop the BSODs. Any ideas much appreciated!

Your error code is 0xA and these are caused by either hardware or drivers attempting to address a higher IRQ Level then they should which results in crashes.

At this point we don't have enough to go on. So...

1. Stay away from anything that does registry because they are mostly a bane to a system.

2. Give us your hardware specs including make and model of your motherboard, make and amount of RAM installed, power supply make and wwattage, video card, etc.

3. Give us the security software you have installed.

4. When do the BSODs occur?
