Thread: not booting but rebooting instead

have you try a different PSU?
Maybe not enough power.

i dont have another power supply to try. if it wasn't enough power would it switch on at all or even try to boot?

You don't have another PC at home? Use an AC PSU to test to see if the PC boot. That will rule out component failure.
If it does, plug back the M1 and remove some of the none essential components like CD/DVD ROM, sound card, wifi, .... to see if it boot with the M1.
If it does, start plug back one component at a time until it doesn't boot. Now you know what to do next.

i tried an ac psu and it boots fine, removing non essential components made no difference. i can only assume the m2 isnt powerful enough.

Your CPU draws either ~65w or ~50w, depending on the core. I'd find out what core your CPU is, as it makes an obviously huge difference in power draw.
Granted, neither of those values are going to push you over the limits of the M2.

Why that video card?
3D video cards tend to be huge power hogs. As a general rule, the newer & more powerful the 3D chipset, the power it will suck away.
I'm willing to bet that replacing the Radeon card with onboard video (if available) or another, lesser video card, your problems booting will all go away.

I can't be 100% certainm, though. You could have a bad ground, a wiring problem that we're not aware of or some other issue. Buit I think the video card is a likely place to start.

My M2 does this occassionally with an SP13000 board

I have this same video card. Its PCI so i can add it to my Via Epia MII1200motherboard. I'm trying to find power requirements for it. I want to be able to play simple FPS games during lunch or traffic jams, Maybe quick shoot out at a stop light

Guess I could get out some amp meters and run some tests with an AC power supply.

Question is, Anyone know how much the 9250 128meg PCI video card consumes in power?

thanks

Try this first, put in windows cd and boot. When it says hit r for repair press r. When the prompt comes up, type chkdsk. You might also try sfc /scannow after that.

Reboot and see if everything is ok. If not, try the sp repair routine...

XP Repair


1. Boot the computer using the XP CD. You may need to change the boot order in the system BIOS so the CD boots before the hard drive. Check your system documentation for steps to access the BIOS and change the boot order.

2. When you see the "Welcome To Setup" screen, you will see the options below
This portion of the Setup program prepares Microsoft
Windows XP to run on your computer:

To setup Windows XP now, press ENTER.

To repair a Windows XP installation using Recovery Console, press R.

To quit Setup without installing Windows XP, press F3.

3. Press Enter to start the Windows Setup.

do not choose "To repair a Windows XP installation using the Recovery Console, press R", (you Do Not want to load Recovery Console).

4. Accept the License Agreement and Windows will search for existing Windows installations.

5. Select the XP installation you want to repair from the list and press R to start the repair.


6. Setup will copy the necessary files to the hard drive and reboot. Do not press any key to boot from CD when the message appears. Setup will continue as if it were doing a clean install, but your applications and settings will remain intact.
