After the tribulations in a previous thread of installing Win 7 on one PC, my own new build has started misbehaving - talk about bad luck !
So, spec is AsRock Extreme4 Z68 with i2500K, 4GB Patriot RAM, Raptor 74GB boot, Samsung 1TB, GTS 250 OC and so on....on a clean Windows 7 Professional install.
The problem is that, as seemingly random times, the PC will just freeze/lockup and the only solution is to hold the power button to shut down. This can happen after 5 minutes, or a couple of hours, and seems to just happen - i.e. sometimes when unattended, other times when trying to perform any given action (examples are: resizing WMP playback window, clicking on a IE window, opening Control Panel and so on - random !).
I have tried removing the nVidia gfx and running from the IGP of the i2500K - this gives a different problem, but same overall result - when it locks up, the screen suddenly corrupts; lots of different colours, like interference ?, but just frozen and, if sound is on, a load of continuous white noise
I have tried disabling everything I can in BIOS; unplugged everything but essential hardware; removed various drivers and so on......to no avail.
Memtest86 run a few times, and no issues.
Event Viewer just gives me Kernel Power error, which simply notes that system was not shut down properly......and there is no consistent event visible prior to a freeze.
Latest attempt to diagnose has involved digging out an old 40GB SATA HDD and installing a basic install on. So, Win7, Office 2010 and critical mobo drivers and that is it......all fine throughout installation and downloading updates.....installed printer driver (MG6150) and still fine......then put on latest nVidia driver.....and lastly Kaspersky IS 2011......and then I got my first freeze !
Interestingly, Kaspersky was difficult to install, and - although it downloaded the latest installer - it gave some message about 'serious problem, maybe infection' and refused to install. I cancelled the installer and tried again, using only the disc and not downloading the latest version, which installed fine......and then my problems started again !!
So, have used System Restore to before the nVidia and Kaspersky install and the machine happily stayed on through the night and no problems using this morning
So.....anyone come across any similar issues ? Certainly starting to think Kaspersksy could be the cause...but not sure why that would be ?!
