Recentley my system has started to randomley freeze for no apparant reason, not long ago i added a stick of 1gig PC3200 crucial RAM to my system wich allready had a 512mb stick of PC2700 RAM, i am aware that the faster stick will run as slow as the slower one but am not too botherd atm. to begin i tried rolling back the system settings because i suspected it mite have been a recent WoW patch update, but it froze again almost straight away. Next removed the new 1gig stick of memory but the crashes continued the i had some advice to try re-installing the CPU wich i did and the crashes stoped! WOOHOO so after a day of leaving my computer on and no freezes i decided yyee i'l whack that 1gig stick in and lo and behold it crashes again that very night i need help as i'm vry confused, i think adding the 1gig of RAM is changing something that must have been reset when i reinstalled the CPU

pppllleeeaaassseeee help me!!!!!!!!

unplug the stick of 512

plug in the 1gb stick

goto www.memtestx86.com

run memtest... that should tell you if the memory is bad

If the mem tests ok you might have to manually adjust the memory in the MoBo Bios.
But that depends on which one you have,some motherboards wont let you do much.
What Board are you using?

Abit AV8 3rd eye

Are you sure your motherboard supports non matching pairs of ram?

i'm prety sure it does but i'l double check just incase

ok, i deffinatley supports PC2700 and PC3200, and i thought having 2 diffrent speeds of memory would just slow the fastest one down to the same speed as the slowest not make you system die, lol.

Read page 2-4 & 3-4 of your manual.
It specifies Identical speed and size moduals ONLY .
Try setting the mem timings in the bios for the slowest modual .
your manual also said to reset the bios after changing mem.
you'll have to buy another stick of 1 gig to get it to work in dual channel anyway .
good luck

mutch appreciated! i will try those things abnd let u know hoe it goes

What those pimps said hit the nail on the head but i thought id throw out some knowledge for you. Did you know that 95% of the time when you Win OS computer freezes, the operating system is actually saving itself. Its an actual function of windows to freeze when certain files are at stake and are being threatened. Certain .dll files is basically what that is referring to. I remember reading a while back on Linux never freezes, which makes it so much better.....Or so we though eh?

How this pertains to your computer? Most likely your mobo is not handling the unmatched ram very well and when it references a file on bootup to your ram for quick access, windows is seeing the instability there and freezes itself to protect the file. Do exactly as the guys said above and you should be gravy man.

ah cheers man good peice of info there, very intresting! yeh i'l have a play and let you all know how it goes! thanks again!

Its a feature, not a bug, suuure...

ok, i have cleard the CMOS and reset the bios to all its defaults whilst only running the 1gig stick of RAM on its own. it's still freezing, it doesn't freeze to soon if i cancel some preocese but it does after a while.

any other ideas?!

anyone ahve any ideas?

Thrill Kill gave you a link to MemTest, have you run that yet? It would be a good start. You might have some bad ram or several other problems.

Beyond MemTest, contact your RAM manufacturer. OCZ helped me out alot, most of them have online forums, could be ram timmings, lots o'stuff.

Good Luck.

I am assuming you have taken care of spyware/virus options. If you have not, that could be a problem. How many running processes do you have when you boot?

E

I have about 41 proceses running, i have done a scan with ad-aware and a scan with AVG anti virus so i should be ok there,

i tried the MemTest website and downloaded MemTes but it didn't work but i' try again!

ok ran memtest no problems apart from it appearded to freeze at one point the time was not changing and the percentages wer not moving but the small cursour thing on the bottom left was flashing

i'm now thinking about trying a format to see if that mite help, any other ideas as a format is a hassle i could do with out!

How many programs do you have start up when you boot? I think I have 18 or 19 processes started when I boot. 41 seems a little high, unless you run a lot of stuff in the background on purpose. Check out the RAM's company website. You might also try updating chipset drivers, that worked for me, but I think I just got lucky!

Here is a link about the running processes, might help you out. http://www.answersthatwork.com/Taskl...s/tasklist.htm

Good luck, keep us posted.

i tested a stick of ram for a trade the other day, laid my computer on its side, tested it, worked fine...

put my old ram back in, ran for a few minutes, crashed....

put new ram in, crashed...

no matter what i did....crashed....

then i realized the fan on my VIDEO CARD had seized up (from dust, and laying system on its side)...

put an old pentium 1 cpu fan on it, my system hasnt crashed in 2 weeks...

...check your video card fan....

cheers you guys, will do!

i'l keep u guys updated, thanks for the help!
