Let me spell out the situation: Back in February, I bought two new RAM sticks for my computer, and put them in. I'm fairly inept when it comes to this computer business, so I accidentally put them in the wrong slots, which of course meant that the computer wouldn't start, so I took them out and put the old ones back in thinking these new ones were broken or something. But when I turned the computer back on, all was well, except games were now super laggy and stuttery. As far as I could tell there was no reason for this. I looked up what the symptoms of a fried motherboard or RAM was, and none of them seemed to fit my predicament. I wasn't losing files, and my computer wasn't randomly blue-screening, so what gives? (As far as I can tell, the stuttering only occured in 3D games as well, by the way. In addition to that, starting up programs also takes longer than normal.) I spoke to a friend of my sister's who knows way more about computer than I do, and she suggested that we reset the Bios. And so, in the course of an evening, we took the computer apart to restart the Bios aaaaand... the situation stayed the same. She suggested that I run Memtest from the boot screen, but there's an issue with that as well. Sometimes, the computer won't even start, just screaming out a series of beeps when I try. Other times, the computer will start just fine. Peculiarly enough, it'll start just fine if I shut down the computer at night, and then restart it in the morning, but not if I shut it off and then immediately turn it back on. Nobody I've spoken to seems to know what the issue is or how to fix it. Is there anybody here that has any ideas?
