This is mt first posting, so i will apologize in advance if i do this incorrectly.
I am working on a friends system that is running XP Home with svc pack 3. At first the system was sluggish, with the occasional unwanted pop-up. And then it started to hang. When i tried to boot into safe mode the system would hang when trying to load agpcpq.sys. So i could not try any test's in safe mode. When i would try to access the internet or even plug in an ethernet cable a window would pop up stating that a system service could not start and DCOM would be shot down and that i have 60 seconds to save my work before the computer would shut down. I tried to update the AVG 8.5 software to 9.0 and the system rebooted right after the progress bar had finished but before AVG could launch. At this point the system BSOD'd from then on. The stop error code was:
0x000000D1 (0x661a001c, 0x00000002, 0x00000000, 0x82BDAC3F) Driver IRQL not less or equal.
To make a long story short, i did i repair install, and am now able to boot to safe mode. Virus scan's come up clean with AVG 9.0, I have run the Sophos root kit scanner and it comes up clean. However i still cant connect to Microsoft site for updates, i can not install spybot s&d, and if the system is connected to the net and left idle for a few min's the system hangs. I would like to post a hijackthis log and see if anyone can spot the cause of my problems.
Thank you in advance for any and all help.
