Hi all, First of all I apologise if this is in the wrong place. Was not sure where to ask the question. I have just built my new system: Mobo: gigabyte GA-p55m- ud2 CPU: Core i5 750 GPU: HIS 5770 Ram: 4GB 1,600MHz DDR3 HDD: Samsung F1 Spinpoint 1TB Monitor: Benq 2220 21.5inch PSU: OCZ ModXStream Pro 600W OS: Windows 7 64bit I have encountered an annoying problem which I don't seem able to get to the bottom of. The computer will boot up with no problems and goes into windows fine. 90% of the time it is perfectly ok, but then sometimes it just hangs, (seems to be random and not associated with any particular programme or process) and the onlt way to restart it is to turn it off and on again. However after doing this it then goes past the splash screen and returns the 'Boot disk error, insert system disk and press enter' and will go no further. Several times windows has tried the repair option which sometimes works and sometimes does not. So far I have run memtest with no problems, tested hard drive, all temps seem ok, and I have done a short stress test on the CPU with no problems. Could it be: 1. Sata cables to hard drive? 2. Sata connection on motherboard 3. Something else ANY help would be appreciated Once again I apologise if this is the wrong forum, J
Just a random thought or two... One thing to look at is display drivers. If you are using the windows driver, then grab the latest ATI driver. if you are already using the latest ATI driver, then try finding a driver that is a couple of months old. I presume that when the machine is stable, it is properly stable. You mentioned a CPU stress test, what about games and gpu stress? Your machine might be blue-screening without you knowing. Have you tried turning off the automatic re-boot after a blue screen? The blue screen carries an error code that might help.
