I suppose the subject explains the issue rather well but I can elaborate slightly. I am using a compag nx 7400 laptop with windows xp professional installed. In either safe mode or regular boot when I get to the login then put in the password hit enter the desktop flashes momentarily and it logs me right out.
Now that is the issue I shall explain how I have gotten here. A friend brought me this laptop with a virus on it that looks like it was one of the numerous fake antivirus programs that have been all over the place lately. After attempts to do anything while the OS is running failed miserably I made some boot disks and have done the following; ran check disk and diagnostics (just to be sure nothing is wrong there save myself some time) everything is ok. kaspersky scan, panda maximum scan, mcafee scan, trend micro scan, webroot analyzer scan, spyware doctor, and finally A-squared. A number of malware's were discovered and removed, in an effort to be thorough as suggested I shall list them. RogueAntiSpyware.InternetSecurity2010, Adware.WeatherStudio, Generic FakeAlert!htm trojan, FakeAlert-KS!Ink trojan, trojan program Rootkit.win32.tdss.y. All were supposedly cleaned, as I can't boot xp i'm not really certain but it was all done prior to boot so there is hope. I should also point out that prior to this I was unable to boot into safe mode it would get down to mup.sys I believe then hang for a moment and restart, after the virus removals I can boot safe mode but the same log in log out frustration occurs.
I have read up on this somewhat and it seems the windows disc repair option has been suggested a number of times, sadly when I try to use the windows disc it tells me it finds no hard drives on the computer. I think I have read somewhere that this is a lack of proper drivers issue and I can make a new xp boot disc with the drivers slipstreamed so I guess I may try that while waiting for a response from anyone willing to help. It should also be noted that using a PE boot I have tried the suggestion of deleting system, SAV, security, default and ahh one other file I can't remember from c:\windows\system32\config and replacing them with the same files from c:\windows\repair I believe it was. Upon doing so the computer wouldn't boot do to some corrupt files so I put the old ones back in and that is all I have tried as of this moment. Hopefully this was thorough enough of an explanation that you guys can come up with some helpful ideas for me, much appreciated in advance.
