I'm trying to fix an old Alienware computer (out of warranty). It randomly reboots. I've checked the event viewer and there are not messages.
Motherboard: P4T533-C
CPU: Pentium 4 3.06GHz
Memory: 1GB RDRAM
Video Card: ATI 9700 Pro
The CPU was clocked down to 2.3GHz by Alienware. I tried booting at the full 3.06 but it just locked up. I'm not sure if there is a middle ground between 2.3GHz or not.
Since there are not messages in the Event Viewer, and it is a clean install, i'm guessing the problem is hardware related. I removed the sound card and the modem to eliminate them as the cause.
I don't have any spare RDRAM memory (who does), nor do i have a spare Socket 478 chip laying around.
Has anyone came across this before? I'm guessing the problem lies in either the Motherboard, CPU, Memory or PSU.

I'm so confused. Is it locking up or rebooting? Does it happen at 2.3GHz or only 3.06GHz?
I would suggest trying a stress utility such as orthos to see if it passes, or if the load/heat might be what causes the reboot. It really does sound like a hardware problem, especially if none of the software/drivers has changed recently.

Sorry, it is rebooting. The screen goes black, then the fans spin back up and the boot-up starts.
It was randomly resetting (rebooting) and locking up before i did a clean install.
Now after the install, it has not locked up, but it still reboots. This only happens at 2.3Ghz, i cannot get it to boot properly at 3.06GHz.

Are you running the memory at a slower speed for the 2.3GHz configuration? How many DIMMs does your system have, and how many slots do you have? 4 DIMMs in 4 slots is a recipe for overheating, especially if they are high performance like RDRAM.
In any case, my guess is that your processor or memory is overheating.

Try opening your computer case and use a vacume to suck out dusts. Check behind the motherboard if there's any short. Check if any capacitors are blown or leaked.I agree with this post. Dust inside the case could be causing cooling problems or maybe even a high resistance short.
Having read the original post again, I would agree with Doglips. If the problem isn't fixed by cleaning out the case(and checking the fans), then it is probably the power supply.

Does your computer reboot when
eg.. when you touch it or move it by accident
when you used the computer for over a certain time
when you plug in a device such as a USB flash drive
running some cpu intensive program even if it only last for less than a second... example: opening task manager takes up approx. 10% cpu power for less than a second.

I already ordered a new PSU, even if that is not it, i can use it in another computer somewhere.
There is no dust. I checked behind the motherboard and it looks clean.
I don't move it, or plug in a USB when it reboots. Currently, i start it up, it boots into windows, either i let it sit there, or i try to go to a website, and it reboots.
So i'm waiting for the new PSU to get here. And i'm going to run memtest86+ on it and let it run over night to see what that gives me.
I tried using TAT (Intel Temp. Anal. Tool) but it said it has the wrong CPU. I know it is a P4 3.06.
In for question about how many sticks, i'm using all 4 slots. If the memtest comes up clear, i'm going to remove 2 at a time and see if it stops the reboots. Now i just need to find the blank memory sticks to run the mem test.
Thanks for all the help, i'll post an update when i got some new results.
