BSOD memory management

[steven phu]

Hi there
I've been getting BSOD the past few days. I did the memtest and everything went fine.
so I used whocrashed program and it gave me this

can anyone elaborate what it means?

my specs:
intel corei5 2500k
xfx 5850 crossfired
asrock z68 extreme 3
corsair vengeance 1600

I've attached my minidump as well.
thanks!

Did you run check disk on the hard drive?

 

[steven phu]

That's where you type "chkdsk /f" or something like that in run? If so I did. Windows dos came up for half a sec then disappeared. That's all it did. wasn't 100% sure if I did it correctly

I took my second video card out suspecting it might be a driver of that and left my computer on while I was at work. it BSOD again. I got these two messages on whocrashed program

[/FONT]the second one is obvious my avg antivirus, which I uninstalled. the first one im not too sure what that means.

Download and install Microsoft Security Essentials:
http://windows.microsoft.com/en-US/windows/products/security-essentials

after you uninstall any other antivirus programs. NTFS File System refers to your hard drive files. To run CHKDSK properly go to Computer, and right-click on the C drive. Select Properties, Tools, Check Now. Select both check boxes to set a disk check on the next start up. If any errors are noted, the hard drive may be going bad. This may be a good time to back up any files you can't afford to loose

 

[steven phu]

ok ty
ill do this right now

 

[steven phu]

I did the chkdsk and it seem fine. I got another bsod

im assuming my hard drive is fine now?

 

[Tmagic650]

Are you over-clocking the CPU or memory?

 

[steven phu]

Just the cpu

 

[Tmagic650]

Back it down and see if the BSOD's stop

 

[steven phu]

Ok ill do that once I get off work tonight. Thanks!

 

[steven phu]

I pushed the cmos button on my motherboard, so everything should be set to default. I still got a BSOD

I noticed that my computer runs really slow right before I get a BSOD. not sure if that would help

 

[Tmagic650]

"I noticed that my computer runs really slow right before I get a BSOD. Not sure if that would help"... Try running Memtest86. Download the pre-compiled 4.20 iso file and burn it to a CD or DVD. Boot the computer with this disk and let Memtest86 run for at least 7 passes. Any errors mean trouble: http://www.memtest.org/

 

[steven phu]

Ok ill do it tom. What kind of trouble? Hard drive dying?
I was on safe mode yesterdat for awhile with no issues which makes me think its got to be a driver issue
thanks again for your input

 

[mailpup]

Since running memtest will be testing the RAM (memory), any errors will mean trouble with the RAM. Replacement of the defective module(s) would be the solution.

 

[steven phu]

I did run a memtest couple days ago and my ram seems fine. Ill try using a differ ram tom and see if that fixes it

 

[steven phu]

ok so I did a reformat on my harddrive. I get it still. Took one stick out. still got BSOD. switched to the other ram. still got it.
so im guessing its either hard drive, both ram, or maybe motherboard?

also I notice everytime I get a BSOD. it wipes out my temp folder.
everytime I log into steam. it thinks im logging in from another computer

 

[Tmagic650]

"also I notice every time I get a BSOD. it wipes out my temp folder.
every time I log into steam. it thinks im logging in from another computer" You may have a virus or other type of malware infection

 

[steven phu]

I ended up reformatting and I still get bsod. It still wipes out my temp folder.
I found out it was my ram that was causing it. I switched rams with my cousins computer. No bsod, but his computer started acting up. Crashing games and other things wouldn't load correctly.

I appreciate all your help and advice

 

[Tmagic650]

Okay, I wonder why Memtest86 didn't detect problems. Was this memory the original that came with the computer?

 

[steven phu]

Im not sure why it didn't detect it. I remember it saying 100% pass when I ran it. This was a custom build computer that I build.
I was using corsair vengence 8gb 1600mhz

Thanks, and good luck
