As I wrote to section 'OS & Software\Windows OS' I have problems with random restarts in Windows XP SP2. Sometimes (once or twice a week) there is random restart without BSOD, system simply restarts without. After restart I get information "System has recovered from a serious error". It is on new PC with Intel E6600, MB Asus P5W DH, 2GB RAM, Seagate 7200.10 320 GB, VGA MSI X1600 XT and the problems last from october. I went through Memtest without problems, checkdisk without problems, there were just some bad indexes on disk. I made BIOS update but problems are still here. There are some minidumps files from last crashes in thread https://www.techspot.com/vb/topic68501.html, please could anyone go through these files? I would like to know where is the problem. Could it be some kind of infection? Thank you.
