First of all I'm not entirely sure if my problem here is software or hardware related, so my apologies if I got things wrong. My problem is that my desktop has problems booting up after I have shut it down the night before. It fails to boot up properly after being powered off over a night and keeps rebooting at startup and failing to enter Windows. This problem has cropped up since yesterday. Here's what usually seems to happen.
1) I start up the computer. It usually runs well at first, cos it manages to enter windows.
2) Once windows seems to load up, the computer reboots by itself.
3) Subsequently, the computer will have problems entering windows after that. Upon reboot, I will usually get one of these 2 error messages (on black screen):
error message 1:
<<<CPU is not working or has been changed. Please check soft menu.>>>
-> Press any key to run setup
when i press any key i enter BIOS setup. here, i will just reset my BIOS and exit the BIOS setup, and the computer will reboot again.
error message 2:
this is the usual message saying that windows has failed to run for some reason, and the message prompts you to either run the computer in safe mode, safe mode with networking, safe mode with command prompt, last working settings or just run windows normally.
here, no matter what I choose, the computer usually reboots again.
4) On some occasions the computer does not reboot (it has rebooted about 50 times..) but manages to enter the black Windows XP loading screen before rebooting abruptly again. On even rarer occasions it manages to enter the blue colour Welcome screen before it reboots. Today, it managed to go all the way to Windows twice. The first time, the computer rebooted abruptly again whilst I was using the comp halfway. The second time, it has managed to work (for about 1 hr and counting), and so here i am asking for help here...
what I did yesterday: Yesterday the same problems were already cropping up. I thought initially it was some software problem, so I inserted my Win XP CDROM and tried to use the 'fix Windows' option. Since this problem is cropping up again today, I think the problem does not lie with Windows. Also, yesterday I tried to shut down and bootup my computer a few times and it seemed to work fine after that. (maybe my problem seems to crop up only after the computer has been turned off through an entire night?)
my system: running WIN XP SP2, pentium 4 2.4ghz, 512MB RAM, system about 2 yrs old, system fan is running well, Speedfan seems to tell me my harddisk is healthy and the computer temperature is fine at 40 degrees C. I have not made any software tweaks to my system recently, and I have not touched any hardware components at all these 2 yrs. Also did a check for viruses, spyware, no results yielded.
I will supply more info if needed. Hope someone can help me!
a side qn: since my computer is having these bootup problems, my temporary solution now is not to shut down my PC at all but to either keep it on standby mode or hibernate mode. Just want to ask u guys- which mode is better/safer?
