All,

I have just built my new PC a week ago and it has been generally very stable apart from 2 random restarts which happened whilst I was installing various software from CD's after setting up windows (which did not show a BSOD but wrote a error stop 102 in the event log), however I did not see any repeat of these, and have been using te PC intensively for office apps and extracting AVI files onto DVD's for watching on my home cinema system.

However until I started playing World of warcraft at the weekend while installing another game in the background from a CD. The machine restarted- no BSOD, no error in the event logs, just the power going off and the machine restarting.

It *seems* that as soon as the DVD drive & hard disk is working while I am doing something graphically intensive, the machine restarts - the only way I could reproduce the restart was to load up WOW and have a cd/dvd related activity going on at the same time. Any time I do this, at some point within a minute of setting it all off, the machine restarts.

I can run the machine stable doing office apps no problem, and have played warcraft for a couple of hours with no problem, and have installed a lot of software from the DVD drive.

Here is what I have checked:-

- Temps - According to PC Probe the CPU runs 45 idle, 55 maxed out and when these restarts happen it has not been higher than 50. I have had it running stable with higher temps encoding DVD's.
- IRQ - graphics card is on it's own IRQ, DVD drive is not sharing an IRQ.

Any ideas what could be causing this? Could it be either memory of the PSU? I have a 620W PSU, so I cannot believe that I am overloading it!

I am going to run a mem test tonight, but also wonder if it could be a PSU issue since the restart seems to happen when I have the graphics card working away as well as the DVD drive and the Raptor? Or could the DVD drive be faulty?

I have the SATA devices working off the Intel ICHR7 controller, the DVD burner working off the secondary IDE channle and the JMicron controller is switched off in the BIOS. CPU & memory are working at default speeds. My case has 4 fans (1 intake, 3 exhaust).

Anyone seen anything like this?

E6600 at stock speed
Artic cooling freezer Pro cooler
BenQ Dvd burner
Mitsumi 7 in 1 floppy card reader
P5W Deluxe
2GB Corsair CL4 DDR2, running at default speed
150GB raptor
320GB Seagate
Gigabyte 7600GT Silent pipe graphics card
Thermaltake Kandalf Case
Enermax Liberty 620W PSU

Hi. I would start off by checking the card reader. I had problems with mine. Is it powered? Have you conected the power cable? Do you have two memory modules? If yes, try using only one. Also, did you install the latest chipset drivers? If all fails, try removing the board from the case and test. It might be that something is shorting. Hope you fix it soon!!!

Sounds to me like a power supply issue. I don't know why it would be a card reader / memory / chipset or board shorting - you'd experience problems with the system whether or not it was under load if it was one of those.

I've had similar problems with the PSU - once the voltage drops below a certain point under load the protection kicks in and it restarts the computer to avoid damage.

Any ideas how i can check the power supply? Dont want to RMA it for nothing....

I had another random crash today (after 24 hours stable running), this time just doing surfing. When I looked in the error log there was again no error, but a system event notification:

The computer has rebooted from a bugcheck. The bugcheck was: 0x1000007f (0x00000008, 0x80042000, 0x00000000, 0x00000000). A dump was saved in: C:\WINDOWS\Minidump\Mini100306-01.dmp.

I looked further and these were generated also when I had the previous crashes. Anyone know how to interpret these files? Help appreciated...
 
The easiest thing is to go to a computer store and buy a $20.00 power supply tester and just connect it to the ATX connector, molex, etc.
Or you could buy a multimeter at Radio Shack and test that way.
Connect the green and a black wire on the ATX connector if you want to manually start the power supply. Keep a small load on the Power Supply while testing.
Here is what a power supply tester looks like:
