I tried to overclock my ram slightly, from 3200mhz (the advertised speed, to 3400) so it wasnt a huge OC attempt. anyways, it failed, got a blue screen and then my pc shut off, as i turn it back on, it comes on but it didn't post. so i read online, they tell me to reset the cmos something, i do that, it works. my pc posts, but now im left with another issue. every game i play has these sharp fps lag spikes, like every 15 seconds or 30 seconds or so itll lag abruptly for a good 2 seconds. i ran the windows diagnostic tool. nothing, i didnt run a memtest. should i?or would reinstalling windows fix this? im honestly so upset about this. i spent so much money on this new pc and there i go and ruin it all.please help guys.
