hi,

I got lots of blue screens, pc hanging-up, applications crashing, games crashing... the last couple days.
they all give me error messages regarding memory.

the pc is actually crashing every 2-3 hours, and sometimes even my windows user profile can't be loaded!
I used scandisk after every crash, and it found no problems.

yesterday I've tested my RAM using the tool from the vista repair console (F8 before windows boot) and it told me that my RAM indeed is damaged!

the wierd thing is that I tested a script to read and write memory with ahk that day the problems begun.
during development my pc crashed, and from then on I had those problems.

I even checked the creation dates of the ahk files, and compared it to the windows system reports, the heavy problems started at the same date as I tried those scripts!

my question now is:
can any of these scripts have damaged my RAM ? is that possible? (scripts attached at the end of this post)

I tried reading on 3 programs: notepad, calculator, and warcraft 3.
on notepad and calculator reading worked, on warcraft 3 it didnt return no value (but I think it's because of anti cheat or it requires debugging privelegs).
btw I don't wanna cheat on that game, I tried to make a useful tool (http://www.autohotkey.com/forum/viewtopic.php?t=50285)

and I tried writing memory on notepad and calculator, and it also worked (I checked the value's using the tool CheatEngine and they changed).

But I remember that I sometimes executed the script, trying to read or write memory to calculator, but I didn't had calculator running.

and another thing is that the CheatEngine tool, that I used to search valid adress points sometimes also showed me adresspoints of other processes instead of notepad/calc/warcraft3 only, so I might could have read or even written to an adresspoint of a random process, but I'm not sure if that is possible because the scripts ask for a PUID.

I also tried things like ReadMemory(0x453000, "Warcraft III") with 0x453000 as well as just 453000 (without the 0x) because it didn't work so I just tried it..

on the other side, my notebook is just 1 year old now, but it had a few crashes (blue screens, haning-up), but only about less than once per month and not lots of successive crashs like I have now. and as far as I can remember the bluescreens usually showed up something about the soundcard driver or the ACPI and not about the memory, while now ALL bluescreens AND application errors tell me about memory problems.

so what do u think?

yes I need new RAM
btw I'm using Vista 32bit, got 4 GB DDR3 RAM (2 GB + 2 GB dual channel, 3068 MB because vista 32bit restrictoin) if that matters..


I used the fscripts form this thread (first and 2nd post):

the short answer - no. Programs cannot damage your hardware RAM. The RAM itself might be cheap or fragile, but software won't make it worse.

It /is/ possible to corrupt Windows in multitudes of ways. I would suggest downloading and burning a linux live CD, botting your computer from that, and seeing how things go. If you still get crashes, you might have a hardware problem like a badly configured CPU (overclocked), or the heatsink might be coming off! The video card can have the same heatsink problem as well.

If the linux CD runs ok, then you might consider reinstalling windows to fix any corrupted system files.

oh my god..

I tired the SFC, first by using "sfc /verifyonly" because I thought it would be better if i just run it in "read only" mode. It said that it found something.. so I used "sfc /scannow", the scan&fix mode and as I feared it crashed during the process, got a bluescreen .. memory something..

after this my windows crashed at every single startup, even in console safe mode..
only thing that still worked was the repair console. then I spent more than 8 hours to use the repair console, chkdsk, sfc (which also crashed in safe mode...), the vista dvd and so on. great! btw its not even possible to use sfc inside the repair console.

then I gave it up and opened the laptop and removed each RAM and used the RAM check tool. one of the RAMs is corrupted, the other has no problems, so now my PC works with that single RAM, but with working RAM I still couldn't fix my old windows anymore... so here I'm now waiting for 93 vista updates to be downloaded..)

I'd say it's more likely that the RAM damaged the software/system files than the other way around. Given your description of usage if it happens again you might also check into the possibility of a faulty power supply.

windows xp manages memory usage and does not allow direct control of memory space or cpu time. if your code did damage it is because windows itself was damaged
