I've formatted my computer about 4 days ago. On sunday I updated my graphics card driver and merged a partition with unallocated space with my c drive. It was fine after 1 boot up but then my father was using it and the screen turned black. I performed a system restore prior to the the graphics card driver update and it worked fine. The next morning, both my mother and father were confronted by this problem again. I returned from school and turned the computer on but it was fine for me. I've even gone as far as restarting the computer ten times and I was unable to replicate the problem. Later on, my father was using the computer and it happened again! I don't think my parents hit anything during the boot. Please help me, it's hard for me to figure it out because I can't replicate the problem and I can do without the smartass answers like "guess you'll have to turn the computer on for your pop and ma." Thank you.
