I have 19″ AOC monitor (1440*960 max. resolution supported), 250GB HDD, 1GB RAM, Intel Pentium D Dual Core GHz, 96MB onboard graphics memory. I have no graphics card. OS is Windows XP SP3.
Whenever I watch 240p and 480p YouTube videos one after another, my monitor would turn off.
Someday my PC shutdown automatically when I was watching YouTube videos. My CPU usage was not beyond 75%. The temperature of the components were:
CPU – 68°C
AUX – 74°C
HDD – 56°C
I was using Firefox 4 and the total RAM usage was 770MB. Such things even happens even when I play lightweight games like Tinker. Two months ago, I had replaced the heat paste of CPU by white coloured heat paste as I had never replaced the paste for 4 years.
Is it graphics related or heat related problem or both?
