I recently started getting intermittant BSOD (0X00000050 Win32k.sys). started happening pretty much the same time I installed a new SATA HD. Don't know if that's the cause or not. Here is the error log :

Anyone got an idea what might be a solution?

ASUS p5p800
P4 3.0g
1g OCZ Gold ram
80g Seagate IDE Master Boot
400g Seagate IDE Slave
320g Seagate SATA
500g Seagate SATA (new drive)

Can you attach or Zip your Minidumps?

Ok here are the minidumps.

Your first dump from 3/29 shows it is a 0x8E error in win32.sys Check out this link that might give clarification:

Your other two dumps report the same thing : Memory Corruption.

Have you attempted a MemTest yet? Have you utilized Seagate's harddrive diagnostic's tool to see if there might be issues with your harddrive(s)?

I ran MemTest and did recieve errors. So I did as suggested and ran each ram stick seperately to see which one caused the fault. Well, they both ran fine on their own. I tried them in different slots but still recieved errors in Memtest. So I figured it must be my motherboard. However, I decided to try a pair of OCZ Premiere series sticks (the ones I was having problems with were OCZ Gold series) I have in my other computer and to my surprise they reported no errors. Now I know I had the timing set properly on the Gold Series sticks so I'm at a loss as to why they weren't running properly.
Any clue?

Did you run those Premiere's in the same slots as the Gold ones without receiving any errors?

How long did you run MemTest on each stick?

yes, I ran the Premiere sticks in the same slot. I ran each Gold stick for over 20 min. 1000% coverage for each one.

The collective wisdom is that the minimum you should test RAM is 10 passes of tests 1-8 and that takes time. 20 minutes is not enough time.

I am wondering if your motherboard has defective slots. What motherboard do you have?

ASUS p5p800

I'll run a longer test and let you know the result.
