OK I'll look at it. Last time we tried memtest86 it didn't boot with the CD.

Yes this is not very useful. It only tells us the PC rebooted without shutting down. It's the exact same message when we press Reset or we have a loss of electricity. RAM is the next test (we will use the one integrated to Windows). I also saw there are updates for the EFI BIOS, but that is more risky, we simply can't work without this server. Heat is surely not a problem, the 20-30 PC are cooled in a closed room and the temperature is monitored and controlled.

Yes the event viewer was the way we detected the problem. We get Event ID 41: Kernel-Power Critical The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. I tried to find any memory dump but could not. I looked if the memory dump was activated and in which folder, it is activated, but nothing is in the specified folder. What is a Server DC ?

Here are the hardware specs: Video card is a matrox G200

Hello, I will start this thread without giving all the information, I will fill it as necessary. We built a new server 2 months ago and we now use it. It's a normal PC box but it does have server hardware. There is one addition: OCZ Vertex 2 180GB which contains the database only. The OS is stored on a RAID1 of 500GB hard drives. This server runs Oracle 11G 64 bits. I'm an advanced PC user but I am not an IT professional. This new server was built following my recommendation because we had problems with the limited memory available in 32 bits. So here is the issue: We discovered 2 weeks ago that the server was rebooting unexpectedly and randomly. There is no memory dump, so I suppose there is no BSOD. I'm still not sure if this could be a power supply problem, a motherboard problem or a Windows problem. We tried a few things. One we didn't do yet is to test the RAM. I think we should do it now, but if it would be the RAM I don't know why no memory dump would be created. Anyway, as I said I will feed-up the information. But any suggestion is appreciated.
