Sometimes my system refuses to boot, like after a shoddy OC or when the RAM is pulled out. It starts working again after a variable no of tries changing the position of the sticks (ie stick A in slot B and vice versa). Sometimes one change fixes it, sometimes it needs a dozen. Also, since this problem started, I occassionally get black dots on the screen. Like the white ones when ones GPU overheats, only black. Lately, games have also been producing dots variable colors, missing textures, corruputed polygons etc. Also, every once in a while I end up with a BSOD.
This started happening about two weeks after I got my machine. After I bought it, the machine wasn't switched on for about a week. Thought it was a motherboard problem, changed my board on warranty. Same problem.
I noticed that in my board's user guide, there was a list of qualified vendors. The serial on the little black rectangular things on my RAM didn't match with any of the ones in that list. Can that be the problem?
