    This service has started to use serious processor time on my machine… 40-50%. Not sure if one of the dependencies are causing the drain, but as you said there are numerous services that depend on it so it can’t be disabled.

    I had the same problem as dre and I solve it by uninstalling the new SonyEricsson PC Suite that appeared for Vista. I also unpaired my mobile from my PC in Bluetooth connections.

    I disabled the Toshiba Bluetooth suite and the problem went away. I think we have it narrowed down to a Bluetooth problem. There are numerous forums on the issues with Bluetooth and Vista, hopefully Microsoft is working on some fixes. To their credit, they finally pushed out a Bluetooth Stereo Audio driver so now I can use my wireless headphones with Vista. Better late than never I suppose.

    What has brought me here and got me wondering enough to comment is the ‘cpu: n/a’. I ended a srvchost process cause my cpu was being maxxed out for no apparent reason and when I ended that srvchost process my computer needed to reboot which was a pain in my ars as I had data transfering that I did not want interupted or compromised by outrageous cpu useage.

    If anyone can help me I would greatly appreciate it, I have a new Dell demension c521 with windows vista , and it is constantly freezing up It usually says web page not responding or something like that , but I’m now getting the message “windows must now restart DCOM server process launcher services terminated unexpectidly. I have no bluetooth programs on my pc ,wondering if this could be a problem with hard drive or is this something I can fix myself? Please help ! a new computer shouldn’t run this slow !!

    Sheila,

    I’ve never owned a Dell myself or ever would put myself through that sort of experience. My first thought was your problem is related to the fact that it’s a Dell system. However I base these comments on my experience with my last employer when they decided to upgrade to Windows based systems and chose Dell as there vendor. I can’t say I have any certain knowledge of the issue as you’ve described. None the less when my previous employer purchased multiple Dell systems for there upgrade it was my responsibility to set them up with our business software via our local office network also to include web access. Throught out this experience it was found that one system had been shipped to us with a defective hard drive. To this end I also found that Dell phone tech. support rep’s are next to useless with there limited range of technical knowledge. However the Dell protocol is that even if you have the onsite srvc term in your warranty the phone rep’s still have you jump through numerous hoops in what they call a sort of diagnostics which is far from that. What I suggest is make however many numerous calls to phone tech support and follow the skew of misc. instructions as well as dealing with the frustration involved in finding the person on the phone is no use in assiting you with any tech. issue. Through the course of this most likely they the first conclusion they will come to is ‘oh it must be deffective hard drive’. Now understand I offer these suggestions hoping you have the onsite support srvc still available in your warranty terms as that will be the final measure. There first suggestion however will be for you to send the hard drive for them to test and so on. Please do not accept this as an option as opening your tower voids warranty and service agreements provided to you with your purchase. Tell them this and that they need to honor the onsite service. When this is honored I believe it will be about two days later or so a tech will show replace the hard drive. That is my best advice unless you find someone to respond here with an abundant knowledge of this process thats causing your problems with a known resolution to solve your issue. Good Luck.

    You’ll need it dealing with those phone tech pions at Dell..=)
