Computer will not turn on with 2 sticks of RAM

Specs: Windows 7, Intel Core i5 2400(3.10GHz) 4GB DDR3 1TB HDD Capacity

Last month my computer would not turn on except for a few seconds and then would shut off immediately only to turn itself back on and shut off. I figured it was my power supply so I replaced it and my computer began to boot normally.

About a week ago my computer would randomly turn off while I was in the middle of doing something. This morning I woke up and my computer had shut itself off and when I went to boot it again, but wouldn't recognized my monitor. So I figured my graphics card was shot, but I figured I'd try removing a stick of ram to see if I just had bad RAM -> It booted. I thought "great I figured it out" but I wanted to make sure it "bad ram" so I stuck the ram back in and pulled the other one out. It booted as well. So I put them both back in and now my computer won't boot with both sticks in and its back to doing what it originally was doing a month ago (powering up only to shut itself off)

Did you clean the edge connectors with a pencil eraser?

Often worth popping the sticks in and out a few times to clear oxide off the sockets too.

Always pop back and let us know the outcome - thanks

Also create a bootable disk with Memtest on it and use it to test your memory, first one at a time and then try both together. Since Memtest runs outside of Windows, it may be able to test both together, even if Windows will not boot to both together.
Compare what the memory speed listed on the label is compared to what Windows reports it to be with one stick in, This may indicate that the memory is not set correctly in your BIOS and may need to be manually set.

Look up your motherboard mfg's website and make sure that the memory included is acceptable for your motherboard. And/or go to crucial.com and let them scan your machine for the proper memory to use and compare that to what you have. Note that specs memory have more than just speed, they have voltage, latency & timings that need to be acceptable and possibly manually set (if it is not properly detected).

You have to be a little bit crazy to keep you from going insane.

Well... I took my video card out... blew the dust off of it and plugged it back in. Then I put all the ram back in. It turn on... and booted up. Now my computer shuts off in the middle of games on its own

Have you now followed all the suggestions so far, in particular:

Cleaned the edge connectors (RAM and Video Card)?

Run Memtest?

Checked RAM suitability?

Presumably the case vents are clear and the CPU heat sink is not chogged up.

So I ran memtest and it ran for 2 hours before I went to bed; about 8 tests in no errors were found (3 passes), but when I woke up my screen as at the login for windows so I don't know if it found any errors or how many tests it ran. (then I logged in, walked away, and my computer had restart itself)

I went to crucial.com and looked up my memory for the gigabyte mother board and my memory doesn't seems to be fine for it.

I also watch my core temps and they never got above 61C

As over as cleaning the edge connectors; how should I do that?

When I get home I'm gunna check the memory speed on the chips and check it with bios.

cleaning the edge connectors; how should I do that?

You take out the RAM sticks, then run a clean pencil eraser over the edge connector contacts. I usually then pop them in and out a few times to ensure there is not oxide on the edge connectors themselves.

If you have a separate graphics card do the same for that and any other edge connectors.

This is not guaranteed to help but it is easy to do and can often cause strange symptoms.

Always pop back and let us know the outcome - thanks

so I tried cleaning the edge connectors with an erase but still it turns itself off

oddly however, once it starts to turn itself off during games it does it more frequently once I turn it back on and load the game back up. But when running core temp it never reads higher than 63C

I'm starting to think this has nothing to do with the memory
