My pc- Asus P4V533 Mx 2 Ghz Celeron 256 mb DDR SDRAM MSI GeForce 4 Mx440 AGP8x the problem - it started after i installed the graphics card into the pc. the pc would reboot during the games i played. soon, my pc would continuously reboot at anytime without warning. it became so bad that i couldnt even start windows, the pc would reboot during the load screen. i was told that a format and reinstall would help. it did, i could use the pc for most normal applications, but not the games. every time i ran the game (fifa manager 06) the pc would reboot. at first i thought it was a driver issue, but the game (fifa manager 06)runs fine in windows 98. other graphics hungry games run fine in the xp installation, so i dont think its anything to do with the drivers. After reading the sticky on this forum by donNagual, ive narrowed it down to 2 possible problems. 1)i checked the event manager tool and it told me that every time the pc rebooted, it was due to an error in "winmgmt". Event id= 28. "WinMgmt could not initialize the core parts. This could be due to a badly installed version of WinMgmt, WinMgmt repository upgrade failure, insufficient disk space or insufficient memory." this is the exact description. i followed the advice given by the microsoft website. they suggested that i use system restore to go back to a previous setting, but id just reinstalled windows after a format, so thats out of the question. the next option they suggested was to repair my installation of windows, i did that but the problem persists. www.eventid.net, gave me a solution, fiddling with the registry and stuff, that didnt work either. can any one here suggest another method to repair this? 2) the only other fault i see is the power unit. i dont know what the output is in my pc, but thats the only other explanation that remains. i downloaded and installed speedfan, according to that the voltages in the 12V and 5V rails were within the 5-6% deviation. but in the 3.3V rail, the reading i got was closer to 3V than 3.1, a deviation of around 8%. is this a problem? and is there any way i can solve it at home without taking it to an expert or something?
