I built my Computer about 1 year ago and in the beginning i had no problems with it, after about 1 or 2 months i started to get bluescreens. In the beginning a few a week so i kept ignoring them, a month later i got around 5 - 10 bluescreens every day... Enoying Error msg was IRQL_NOT_LESS_OR_EQUAL i located the problem to something with the USB so i started to try the different USB ports, and turned out that when i wasnt using the one of the 4 i had on the back of the computer it was fine. After that the computer worked fine for almost 6 months until i moved it to another room, then the bluescreens kept comming back, Sometimes the same error msg IRQL_NOT_LESS_OR_EQUAL and sometimes MEMORY_MANAGEMENT a few times it didnt have an error msg. I tried to take out one of my Ram sticks but it didnt work... Then suddenly after a week (i didnt do anything) the bluescreens were gone for almost a month but now they have been coming back again... does anyone have the same problem or something like this? Can anyone help me to find out what it is?
