My System Specs

Default Faulty Ram? Help!

Hey guys,

I recently bought a pre-built computer from NCIX warehouse sale (the cheapest out of the 3 in the preview video from linustechtips), and I was super happy that I got the computer. When I got home, my bud and I decided to boot up the system and see what was installed on it. The system booted up to the windows 7 desktop... and short after (maybe 1-2 mins) the computer BSODed.

Since I didn't have time to troubleshoot the computer yesterday, I decided to troubleshoot it today.

At first I thought it was just an installation error, so I decided to install windows 7 again and take the computer out of RAID0. When I was installing, there were no problems, and after say 5 mins, the computer BSODed when I was on the desktop page...

So now my thoughts were that the ram was faulty, so I decided to take out 1 of the 2 sticks, and start up the computer from there. There didn't seem to be any problems. And then I swapped the ram and tried it again, and it didn't seem to have any problems (granted i didn't really leave the computer on for too long or do any other tests on it). Also I did the memory diagnostics test that's in windows 7 by default, and it didn't return any problems. Now I returned to what I had in the beginning, and I installed the two sticks back inside, and booted the computer up, and did the memory diagnostics again... no problem.

Now I'm really scratching my head. I personally don't know what memory diagnostics does... but that was what I had at the time, so I used it.

Now when I left the computer running, I heard a beep sound... sure enough the computer probably BSOD'd and restarted. Then from there on it was constant crashing. I thought it was the hard drive failure, however the computer did a CHKDSK, and it didn't seem to have a problem. Now I tried to reinstall windows 7 (with two dimms inside) and it refused to install, it popped this error at me (0XC0000005). I did a little bit of research and it seems to be related to faulty memory and some other issues.

Excuse my lack of experience in diagnosing computer issues... I'm really thinking this is faulty memory, because after poking around the interwebs some more, I ran into this link and it said

Quote:
  • Blue screens of death during the installation of Windows XP or Windows 2000. This is an obvious sign of faulty RAM.
  • Crashes or blue screens during normal operation of the system (emails, web surfing etc.)
  • Crashes during memory intensive tasks such as using Photoshop, playing 3d games etc..
It was certainly crashing when I was installing win7 with two dimms installed. And it did certainly crash when it was doing normal operations. Now I understand that I didn't do any memory intensive tasks, but I decided to include that in there anyways... lol

I've removed 1 dimm, and installed win7 (32-bit if that matters) twice successfully with 1 dimm installed (I don't know if this is the faulty one..)

I haven't swapped the ram in my main rig (that I know works... since I'm using it...) to the computer there, I'll see if I can do that tomorrow.

I haven't done any memtests, because I'm lazy... =P (only spent about 6 hours troubleshooting)

What do you guys think?
