Computer randomly locking up
My computer randomly freezes completey with no error messages, sometimes within a few minutes of booting other times its fine for a couple days. Since this starting happening there had been no changes to software or hardware. It will freeze in all apps, while browsing internet, gaming or just on desktop. So far I have scanned for viruses using NOD32, and trendmicros housecall. Run adaware pro, and spybot search and destroy. Run my registry cleaner, cleaned all temp files, and defragged. Updates BIOS, Catalyst drivers and disabled active desktop.
When the CPU freezes so does the clock and there are no events in the event logs to correspond to the time that it freezes or even near the time. My CPU, vid card, and mobo temps are all fine. All fans are running fine. I have also run SCANNOW /SFC on my windows installation. And all windows updates are installed. I can't think of anything else apart from replacing memory or PSU and hoping for the best. Any other suggestions would be much appreciated.
Here are my specs
