My computer all of a sudden became very unstable and i dont know why. I reformatted my hard drive and tested all 4 gigs of my ram by themselves and 2 stopped working at the same time his happened but the other 2 are fine. When i try to play any game even HalfLife 1 i crash constantly, that is with 1gig of ram in, if i put both working sticks of ram in i cant do anything without it crashing and don't know why. if you have any ideas i would love to hear them, thank you for reading :) I am running a Q6600 core2duo 2.4ghz an HD4870 and now 1 gig of Ocz 1066 ram on a Striker Extreme motherboard and a 750 watt psu

Something like this happened to me a few years ago.. Have you cleaned the inside of your PC? Specifically, have u checked to see the amount of dust/dirt that has accumulated on and in and under the CPU? If you haven't cleaned out the inside of your PC, do it now and try again. If the above is not the case, then perhaps it is your motherboard. Clean out the memory slots on the motherboard and try it again. If that doesn't work, then try your memory on a friends computer. If your memory works perfectly on your friends comp, then it's your motherboard.

Why, oh why, do people immediately pull the trigger on the reformat gun?? RAM doesn't just selectively stop working. Make sure it's fully seated & snapped into the DIMM slots. Pop them in & out a couple of times to clean the contacts. "and a 750 watt psu" Why no specifics on the PSU? Make/model & amperage specs. And post both your system & CPU temp readings.

Haha because the reformat gun fixes everything... well almost everything :/ yah i tried the dust thing but i will try again :) darn if only my friends had decent comps to test the ram on, any other ways i could go about doing that? i don't have the specs on my psu sry and my system temp is about 32c and my cpu is about 45c avg and thank you for the help :D

ok so i fully cleaned all the dust out of my computer... used compressed air and everything and it didn't help so is there a different way of testing my ram? besides trying to boot with only the stick I'm testing in?
