Hello there. 
  
A friend told me Aida64 was the best tool to perform tests on overclocked computers as well as on stock ones, so I decided to test on some old pcs we have at work to recover. 
This said, one of the pcs crashes with an instant blue screen when running cache stress test. 
I was wondering if this is the CPU cache and if so will the CPU have the same issue with another board? 
I just want to make sure it's not the motherboard with some problem. 
  
Pc's a Pentium D 945 3.4GHz 
foxconn board P4M800P7MB-RS2H 
Hitachi sata 3.0 82GB hdd 
using onboard graphics 
  
All other tests alone kept temperatures inside the normal values. 
  
Keep up the good job.
