Hi, I have resolve the problem I had.
My CPU with the following components:
Mother board Intel DH55HC
Proccesor: Intel i3 530 2.93 ghz.
Ram: 2 modules of Kingston KVR1333DDR32GB
Video: Zotac GforceGSO 512 1GB DDR3
PSU: 500Watts 10 amp 5.5inch cooling
HDD: WD Caviar 250GB sata
DVD: Samsung 22X sata
The problem I had was an espontaneously reboot, even if i wasn´t working and in stand by.
Was a conflict in the OS windows 7. This Saturday I reinstall the OS and now is working excelent. The computer has been working since saturday without turn it off, and never comes again the reboot.
The problem beguns when I tried to install an unsuport device and I had to reinitiate several times the computer. I hope this experience can help somebody else.
is it about the Power supply...
i bought recently my PC with following configuration.
INTEL DH55HC MOTHERBOARD
MSI R4350-MD512H GRAPHICS CARD
DDR3 KVR1333 2GB * 2 = 4GB
COOLER MASTER CASING WITH 400W POWER SUPPLY
INTEL CORE I7 850
sometimes the PC is restarting again and again.
i try to load with the Ubuntu 10.10 but when i try to access to the HDD PC is restarting.
i remove all the parts and fixed again and switch on but again same.
i remove HDD and try t load. sometimes restarting.
I wanna know is it problem with the MainBoard?
is it problem with the Power Supply?
Is it Problem with the Graphic Card?
Please let me know?
Intel Guys Please
Wow, want a mix of issues. OK
1) Power supply -- maybe - How much power does your configuration need?
A quick check is add up the wattage on every thing you have installed and then double that to get your power supply rating.
ie. 100 W processor, 75 Watt mother board, 25 watts per HDD, 25 to 100 W video card = ~ 300W X2 = 600 watt power supply.
2) Memory- folks think that the processor is the heart of the system? Na, it is the memory. Intel test memory with the mother board and those memory vendors who's DIMMs pass, get put on the tested and approved memory list. Those that fail don't. Now not all memory vendor submit memory for testing, but if it is not on the list it may be because it has issues. What type , single bit and multi bit data errors are the most common. This means that what ever data or instruction that was being held in memory for the processor got changed to something else unexpected. You see stalls, hangs, data errors, blue screens to name a few common failures.
3) Down Rev. BIOS -- Nobodys perfect.When a computer manafactures finds an issue, the fix is 9 out of 10 time a BIOS or driver update.
Check out the support page http://www.intel.com/p/en_US/support/highlights/dsktpboards/dh55hc
Check to see of you have the most current BIOS and drivers. http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Desktop+Boards&ProductLine=Intel%c2%ae+5+Series+Chipset+Boards&ProductProduct=Intel%c2%ae+Desktop+Board+DH55HC
4) HEAT - the processor is protected. If it gets hot it will 1st slow down, then shut down. Everything else on the board will cook. Make sure all fans are operational. Make sure your system is someplace with good ventilation. Stuck in a desk drawer or closet is not good. Neither is under a pile of papers on the desk. Tools like CPUID HWmonitor http://www.cpuid.com/softwares/hwmonitor.html will tell you how hot your CPU, HDD and mother board is running. Do you know the 2 most stress full task most people do to a computer? STARTUP and SHUTDOWN. Both work the CPU pretty hard and if your cooling is marginal can cause hangs.
5) Add in cards. -- Remember the support page? Check out the tested hardware list before you buy options. Same reason as the DIMMS. Not everything gets tested and that that is tested, not everything PASSES. If it is on the list, it was tested and did PASS. I have a video card in one of my systems I love. High end card, only it has an issue releasing it's PCI config space on a reboot. 1/2 the time it hangs on the reboot shutdown and the other 1/2 of the time it blue screens on as it comes up out of a reboot. Can't be fixed so I live with it. No reboots. Shutdown and Power back on only.
6) OS-Keep it updated. All the OSes out they POST regulator updates. They don't do this just because it is a fun way to make a living.
7) Anti-virus -- Check out the virus maps for the last month http://mastdb3.mcafee.com/VirusMap3.asp?name=VirusMap&b=IE&Left=-180&Bottom=-90&Right=180&Top=90&lang=en&ovb=1&ft=JPEG&ocm=1&viewby=1&track=1&period=3&choosemap=1&Cmd=ZoomIn
Thousands of infected computers in every country. Get an anti-virus, keep it current and run a scan frequently.
8) Diagnostic software.-- http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Desktop+Boards&ProductLine=Intel%c2%ae+5+Series+Chipset+Boards&ProductProduct=Intel%c2%ae+Desktop+Board+DH55HC
or CPUID HW monitor or any number of other test software that are design to help isolate issues..
