I have a Lenovo m82 computer that I am having some issues with. Last week the computer started up slowly, took forever to bring up applications and would hang up on random tasks (bringing up Computer directories, starting a browser, etc) then it would seem to work fine for a little bit before exibiting the same problems. When I brought up the task manager nothing seemed unusual for the CPU or RAM usage. The last installed program was two days earlier so I don't think that was causing a problem. Nor had there been any recent updates as far as I could tell.
I ran a virus scan to see if there was some sort of malware. First I used Miscrosoft Security Essentials as that is what we use. That turned up nothing so I installed Malwarebytes, started in safe mode, ran rKill and ran a scan there. Nothing turned up. I also ran TDSSKiller still nothing. So I am fairly confident that there isn't a virus.
Looking at the Event log nothing seemed to be showing up there so I decided to try a RAM scan. I used the windows 7 tool and ran the basic scan and everything was fine. Yesterday it started having the issues again pretty bad so I took a look around and still couldn't find any problems. Then in what was probably a really bad idea I did the important windows updates thinking maybe somehow it would help. Today when the computer came on it said that 'windows couldn't connect to the group policy.' It took a while, but I fixed it using the solution from P.L.X here http://answers.microsoft.com/en-us/windows/forum/windows_7-performance/why-wont-windows-connect-to-the-group-policy/b73107f8-8447-4599-87a5-65ecc6a63aa0?auth=1
Finally standard users can log in, but the computer is still really slow. I would like to roll back, but there are no restore points to go back to.
I saw a Blue Screen of death at one point today that said something about the kernal but it restarted before I could see anything else. So I figured I'd run a disk check. Well, it gets to stage 5 to about 10% then shows a Blue Screen of death that says something about "ad_system_config_info". The screen is cut off, but looking it up looks like it is bad_system_config_info.
Now I am stuck in a loop cause the system is trying to get through the check disk, but it can't complete due to a BSOD so it starts all over again, BSOD etc. I don't know how to prevent it from starting up.
So I have two problems. How do I stop this check disk BSOD loop and what is causing the problems with the computer? I think the BSOD is related, but when I looked the BSOD up it looks like it is RAM related? However I can't do anything with this computer at the moment. :-/
