Beyound the before mentioned problems, my computer properties just told me I had only 512 megs of ram. when I first started it up it said I had the 2 gigs of ram when I checked (minus the 4 megs of shared ram) The computer imediately told be there was a system error and restarted. Info I have found online about all these problems have one basis of possible resolution. A bad power supply is the only common rectification for these problems. Could it be affecting processor speed, network speed, the memory glitching, bad processor recognition, error fetching codes, ram errors?
