Ok here is the problem, my computer keeps shuting down and some the lights stay on and the cpu fan stops but the power supply fan is still runs. Very randomly it could stay on 5-10 hours ever since i put in a new Nvidia video card and 1G of ram before it had ingrated graphics and 256 ram.
Now it doesnt even get to the login screen it shutdowns at the loading Windows XP. I play heavy run down games like World of Warcraft too.
Now im wondering if its my power supply i tried safemode taking out the new stuff that i upgraded like the ram graphic card etc. and putting back in the old.
