RAM Issue - Windows 7 crashes but Linux runs fine

post #1 of 4
Thread Starter 
Warning: wall of text below, sorry.

I recently left my laptop (Acer Aspire 7741G-6426) out in my car for a few hours and it got really cold, in the single digits in F. I had to copy a file for a project and so turned it on when it was really cold in a normal room (not really thinking about potential consequences). Windows quickly froze after I logged in and it started loading services and programs, so I shut the laptop down and tried again. Same result. I thought it might be because the processor was locking up or something due to the temperature, so I left it off in the room for a few hours. Since then, Windows has continued to freeze. It can sometimes go for about five minutes, then things start to not respond and eventually explorer stops responding and I can't do a thing.

One might first suspect bad sectors on the HDD, but I have run sfc /scannow and chkdsk but both have said that the filesystem is fine and there is no issue with the HDD.

Okay, now the weird part - when I load up Fedora, it runs just fine for an indefinite period of time, except for when I tried running a game through Wine (which naturally would take up significant amounts of DRAM).

So then I started to suspect my DRAM being the issue. When I tried booting up memtest86+, it rebooted right away without even testing. I read online that this can be caused by older versions (I think it might be 3.0 or 3.5, not sure to be honest as it's on a USB stick) and that if I disable legacy USB support it wouldn't happen, but the BIOS on this board is terrible and doesn't offer me that option.

So I have not had a successful memtest86+ test run on these modules together. I have yet to try either module separately - must upgrade to latest memtest86+ version.

I also tried booting with only one of the modules in at a time, same freezing occurred.

The laptop has 2 x 2GB DDR3 modules of some random brand - "Nanya". Not sure if the memory is just poorly manufactured and this is the result, but I want to do a few more tests.

I want to upgrade to the newest version of memtest86+ and run a diagnostic if I can without restarts. I also want to test each individual module as I said before I draw any conclusions about what to do next.

My laptop was purchased in April and is still under limited warranty, so I think they would cover DRAM module replacements, but I may also just purchase my own off newegg and do it. I want to make sure it is the DRAM first though and not the motherboard.

What do you guys think? Is it the DRAM or the motherboard? More info will come soon after I do the tests I mentioned, I'm just waiting until I get home. And if this is the wrong thread sorry, I posted it here because this aspire has an Intel i5 480M cpu.

That's really strange... I've never heard of cold hurting a computer =\

Unless, now this is a stretch.... you took it straight from your car to inside where it was much warmer and turned it on.. If there was humidity in the air, you might have gotten some condensation inside of it, and if thats the case, you're going to have all kinds of problems

Thats just my guess though, I've never actually seen that happen

Definitely the DRAMS are the problem, you better asap give the laptop to manufacturer to fix this problem until warrant expires.

That has been my guess too, as much of a stretch as it seems.
