I am having a problem with my PC booting My computer wouldn't start, it doesn't even show the blue start up screen. I walk into my room one day, the computer starts up with the strong fan sound, and all a sudden it sounded like its in a sleep mode or something, nothing I press on mouse and keyboard made it works. (the fan sound is usually strong up untill my window xp complete started) The monitor doesnt detect the computer any how, I don't think its the monitor connection problem because I turned on the speaker and wait and there were no window start up sound... The only way I get it work is to unplug the power supply entirely untill the back LED is off, wait a while and plug it back and turn the pc on.... it takes multiple trials though... Is it more like a software problem?My computer was bought few years ago - HP m7000 desktop <<< System Summary >>> > Mainboard : Asus LIMESTONE > Chipset : Intel i945G/GZ > Processor : Intel Pentium D 820 @ 2800 MHz > Physical Memory : 5120 MB > Video Card : NVIDIA GeForce 7300 GT > Hard Disk : Maxtor (250 GB) > Hard Disk : Generic (160 GB) > DVD-Rom Drive : HL-DT-ST DVDRRW GWA-4166B > DVD-Rom Drive : TSSTcorp DVD-ROM TS-H352C > Monitor Type : Samsung SyncMaster - 22 inches > Network Card : Intel Corporation 82801GB I/O Controller Hub LAN > Operating System : Microsoft Windows XP Professional SP3 Thanks a lot for your help!!!
