Hello everyone, and thanks for looking at this and trying to help out. This computer runs Windows XP sp2 and has been locking up for a few months now. There is no particular time when it does, but sometimes it happens twice in one hour, but less than 5 times a day I'd say.

When it locks up, usually when I have music playing in windows media player, and have something up on youtube at the sametime.. but youtube may not necessarily be playing at the same time, the sound gets stuck and plays really fast and Num lock on the keyboard stays on all the time even when I hit the button, mouse pointer doesn't move, etc... so basically a computer lockup.

I've had no problems before running 2 sounds at once or 2 players at the same time with a youtube video going or whatnot, but sometimes there is a small noise or some sort of hinderence that slows down the song when playing just for a few seconds and usually a while after that, the computer locks up. Hmm.. I look in Event Viewer and I get 4 Error Messages everytime it locks up and the computer restarts. The error messages are:

"The Parallel port driver service failed to start due to the following error: The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.

Timeout (30000 milliseconds) waiting for a transaction response from the nvsvc service.

Timeout (30000 milliseconds) waiting for the IMAPI CD-Burning COM Service service to connect.

The IMAPI CD-Burning COM Service service failed to start due to the following error: The service did not respond to the start or control request in a timely fashion."

and I also get a Yellow exclamation point Warning found on Event Viewer before the Errors happen or take place saying:

"TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts."

Another thing is I look in Event Viewer on my other computer and there are also warnings about the cd-rom drive in that as well, but I have not had any lockups on that one like this computer does.

One time when I restarted this computer after a crash, windows error report was generated and took me to a webpage saying that the RAM has been corrupted or something like that, and I suppose that would make sense if it was the memory for everything to freeze up, but wonder why Event Viewer doesn't say it was the RAM or whatnot. Is there some kind of test I can do to see if it is really the RAM that is causing this?

The motherboard, cpu, and memory had been changed on this computer for probably half a year now. I made sure I had gotten the right drivers and all, but maybe I didn't get all of them or something. The other computer is not really a custom built one, but a new harddrive had been put into that one, and I had made sure I got the right HP drivers downloaded to it, so I assume the cd-rom drivers are correct on that, even though event viewer has a warning every so often about the drive. Thanks for any info on how to solve this, I really would not want to reformat the harddrive if that is what it sounds like needs done in case old drivers from the last system may still be in here somehow or interfering.

I am not sure nowadays if the computer was left on all night if it would have been locked up by morning or not. Maybe if I left it on all night with a song playing, it would more likely lock up, than having it on all night without any songs or videos going. Hmm..

Also another note maybe to mention is sometimes Windows Live One Care is turned off on it's own for about a maximum of 5 minutes at times, but it hasn't really been happening that much often now. When it did though, it was after it loaded when windows restarted or had started and it came up as normal, then just goes away and a red X says there is no Firewall installed or whatnot and I can't select the turn on button or that is how it was when it was happening. Well just things to mention in case this may ring a bell to some, thanks for any help. I would just like to have computers that don't have any warnings or error messages or problems occurring or at least not so very often. The warnings happen everyday though.
Have a nice day!
