View Full Version : Computer keep restarting

05-12-2008, 02:27 PM
My computer keeps restarting just when its first screen shows. I have replaced with new powr supply, IDE cable and reset bios and it is still the same. If I unplug the HDD, it will show no operating system found and stop restarting, I doubt that the HDD maybe the problem, is it possible? I am running a chkdsk, what else I can try?

Many thanks for helping me.

Whats the specs of it?? Is it an AMD (HP or Dell), or Intel system?

If XP is on it, you didnt install SP3 recently did you?

Well obviously if you disconnect the hdd, it'll say no OS.

I hope you didnt disconnect the hdd while the system was running and it was restarting. It'll corrupt the data on the hdd

Did you reconfigure the BIOS, then save the settings, after you reset it??

It is a HP pavilion 544a, a crap computer with celeron 2.2Ghz CPU, 256mb ram. I didn't do anything risky as you mentioned. I cofigured to boot from HDD first in the BIOS setting and I don't have a clue what else I need to do. Checking disk is done and fond no problem. I tried to do a repair installation, but it restarted before entering the installation mode.

If XP is on it, will it boot into safe mode (press / F8 down, after you reboot).

Or does it reboot before it gets into safe mode as well?

It reboots before I can enter safe mode.

Could be like a PC I have in the workshop - booted into the start of windows - drivers loading - WHAM reboot - one of the two sticks of RAM were faulty.

have you done a RAM test - if not you can get Memtest86 (http://www.memtest86.com/) - download the first ISO file, or Direct link (http://www.memtest86.com/memtest86-3.4a.iso.zip), unzip it then burn the ISO with your ISo burning section of your burner program or if you dont have one get BurnCDcc (http://www.terabyteunlimited.com/downloads-free-software.htm) Second one down, install , open locate the ISO file, put a blank CD in the drive - burn the CD - then boot the problem PC from it, let it run through at least twice - anything in red is a NO NO

Your P C has a floppy disk drive.
Try booting from it.
