Hi I have an old rig that is playing up. You will be in the middle of doing something on it and the screen will turn black. You have to reboot the system for it to work.

My guess is its the PSU so i put the PSU out of my new pc and it hasnt done it since. I need to confirm whether i should get a new psu. It originally had a xsonic in it and the pc is about 13 years old.

Intel pentium 4
Xsonic 450w PSU
Windows XP

Thanks
