I,v had a few Blue screens of death lately . The first one happened when i tried to move a video screen ( I was watching a video ) . I thought that may have caused it because i did'nt move the screen properly . I tried to update window's earlier today , that was on ages and ended up with a BSOD . I also tried to repair the PC with the installation disc but that did'nt work either .Thank you NettleWarbler .
