Hi The other day I downloaded an update for Firefox and while I was scaning the download for viruses computer just turned off and restarted by itself. I checked event viewer under application, sure enough there was an error: event system. I double clicked it and scrolled down the event properties, the discription says: The Com+ event system detected a bad return code during its internal processing. HResult was 80040154 from line 44 and ds:\comxp_sp3\com\com\ix\etc\events\tier\event system obj This may indicate that the com+ event system is not properly installed. Please try to reinstall the Com+ event system. I used the pc few time after that then turned it off using hibernate mode. To day when I tried to turn it on the button lit up with a yellow light instead (usually) green light, and nothing happens, and then turns off again.I unplugged the cord, pressed the button for 30 seconds, plugged it back and nothing happens. Please help. If I can get it to start and boot may be it tells me something.Thank you verymuch. conputer is desktop, windows xp , home edition. I got it old about 5? years.
