Mini080606_29.zipHi, Although I have been around PCs for a very long tim, this is the first time that I have a persistant problem that has stumped me. It is also the first time that I am reading dumps which is also very confusing. Here is the problem; My pc keeps on crashing. It seems to be random but even with my system sat at the User selection stage of bootup, it still re-boots itself. The funny thing is that when the system is active, like now, I do not appear to have a problem in that it does not re-boot. It is only when the system is idle. I have managed to find the *.dmp file and read it with WINDBG. When I load it in, it points to Image Name csrss.exe. When I search on the net for any information, I find mentioned that this is a fundamental part of XP and therefore can not be deleted etc. Also that it has been targetted before by a Virus. I have run applications that can check with negative results. Now I am stuck as to what else I can either use or find out from the *.dmp file. I have attached the file just in case someone out there can read it and give me a bit more information. Any and all help will be much appreciated. Cheers, Jimbo It looks like the upload has failed due to the files extension. I have therefore ziped the minidump and hopefully it will be uploaded then.
