winXP Svpack 3 Home edition ENG, AMD Phenom Quad-core, ASUS M2N SLI, 2GB RAM DDR2, HDD SEAGATE 500GB, ATI Radeon 3870 512MB GDDR4 PCI-E.
1.) RAM tested by MEMTEST; 2x always 7 hours at minimum. No errors.
2.) HDD tested by chkdsk. No errors.
3.) XP reinstalled, sound, video card driveres updated, BIOS updated, chipset updated.
4.) Antivirus + firewall changed without any positive result.
5.) No new hardware pluged though the computer is "relatively" new i.e. everything may be the cause.
6.) XP hotfixes installed.
7.) As I remember the BSOD appeared whed I was connected to DC++ (P2P network)...
Actually I still do not have the answer. The guy on that website checked my memory.dmp file, drivers and also the system for malware. Nevertheless without specific success. Finally he recommeded to change the firewall (Zonealarm) and uninstall daemon tools. Nevertheless it did not help much as I had the BSOD again. Based on this I tried to be less sophisticated and just tested the memory sticks but not by software (i.e. memtest) but I released one of the sticks and also changed slots (I have two memory sticks and four slots). Somehow it seems to be working as BSOD dispeared. But what was the main reason I do not know. (Obviously, one could tell it is a slot because currrently Im using both sticks however one is different slot and the system is stable, nevetheless my motherboard was tested by wholesaler without problem). This 0x....50 fault is quite tricky.
What I recommed:
1.) Test your system for malware by gmer (search in google) or better reinstall. Install only necessary software and slowly add the rest. Update drivers (video, soundcard, BIOS, chipset...). If you are lucky you will find the problem program.
2.) Run memtest at least few hours.
3.) Release memory sticks and use only one and in different slot. You will, see whether the system is stable or not.
4.) Check your HDD by test tools released by the manufacturer and by chkdsk.
5.) Check the video card.
