randon reboots (event log says bugcheck)?

[shock311]

Hi guys, I've been trying to find information on why my comp is randomly restarting. Just to try to eliminate problems, I was hoping that the psu was the problem, anyway here are my readings using Speedfan at idle.

+3.3V = 3.26
+5V = 4.92
+12V = 11.86
-12V = -7.01 why isn't this close to -12
-5V = .18V why isn't this close to -5
+5VSB = 5.51
VBAT = 3.18
VCore = 1.55

I'm a newb when it comes to this stuff so any help is appreciated.

BTW: CPU idles around 30C and under load 38C so its not overheating. its a 2.6c, I've also run memtest86+ to see if the ram was faulty but it passes, which are 2 x 256mb of Corsair XMS pc3200 cas2, and the motherboard which is an Abit VT7, which uses the PT880 chipset by VIA.

EDIT: Ok, after each reboot the event viewer shows that a bugcheck occured and is the reason why the comp keeps restarting. This is what it shows:

The computer has rebooted from a bugcheck. The bugcheck was: 0x1000007f (0x00000008, 0xf87d5d70, 0x00000000, 0x00000000). A dump was saved in: C:\WINDOWS\Minidump\Mini031004-01.dmp.

I dunno what that means, any help would be great.

I'm now thinking its either the processor or the motherboard, which one sounds like it might be the problem and how can I check, I was running Prime95 without errors once and it restarted but in the log for it shows each test up to the restart "passed"

What model power supply do you have? A lot of those voltages are low...

Actually none of your voltages are out of spec though I don't generally look for the health monitor chips to be very accurate. Get hold of an accurate DVM and measure 'em. That's the only way to know for sure. But random restarts are usually either PSU or memory. First reseat all your power connections including the AC cord. If no change, then try reseating your memory. If still no change, then try swapping them out one at a time and/or run the free memory testing programs from M$ and memtest86.com.
. The reason the negative voltages are so far out of range is that nothing uses them anymore and it's hard for the regulators to regulate without a load. My current PSU (a Delta) doesn't even have those voltages.
. Even though they are vestigial, it's nice to have them for playing around with fan speeds because you can rig steps from 1.7V to 24V using them: 1.7, 3.3, 5, 7, 8.3, 8.7, 10, 12,15.3, 17, 24.

First, I'd turn OFF the auto-restart feature of XP after crashes.

- click on the Start button.
- right click on the My Computer item in the Start Menu.
- select the Properties item from the Context Menu that scrolls out.
- click on the Advanced tab.
- click the button for Settings under Startup and Recovery.
- click to remove the check mark next to Automatic Restart.
- click OK.

Reboot.

Next, look at your "Event Viewer" in XP. This logs errors, crashes, and other system messages. To view these logs,

- click Start
- click Programs
- click Adminstrative Tools
- click Event Viewer
- click on System log

Note any entries preceded by a red icon. You should see some common entries (repeated errors) if this condition happens to you often.

Also check the Applications log for the same red icons and their associated info.

Report back.

(You can also get to the Administrative Tools applet via Control Panel).

For more info about the Event Viewer, here's a good if not basic page:

ok, I looked in the event viewer, I get this for my restart

Error code 0000007f, parameter1 0000000d, parameter2 00000000, parameter3 00000000, parameter4 00000000.

so what does that mean?

What, did it say above that?
