Good Day to all of you. Can you help me in this kind of problem? I dont know whats the problem on my PC. The model is Intel P4 1.5Ghz and on Jetway P4MFM motherboard. I buy a new harddisk because the previous was corrupted. When I install for the new OS which is WinXP, i encounter always restarting of my PC. My installation for OS does not continue. It always restarted when exactly the computer is detecting the Plug and Play,exactly when the monitor flickers, then it will be restated again. And sometimes it stocks and does not respond for a long period of time. What seems to be the case? Is it in the motherboard issue? Does the damage in hardware or just software issue like just upgrading the BIOS? Please advise.... Thank you very much and more power to all of you... God Bless.......
