Vista PC restarts 3-5 seconds after shutdown
I have a [COLOR=blue! important][FONT=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif][COLOR=blue! important][FONT=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif]pc[/font][/font][/color][/color] that I built a little over a year ago. It has a Asus P5KC MB, Intel 8400 duel core 3.0 gh 45 nm processor 4 gigs of RAM. I am running [COLOR=blue! important][FONT=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif][COLOR=blue! important][FONT=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif]Vista[/font][/font][/color][/color] 64 with office 2007, open office, solidworks 2005, windows live 1care is my [COLOR=blue! important][FONT=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif][COLOR=blue! important][FONT=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif]security [/font][COLOR=blue! important][FONT=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif]manager[/font][/color][/font][/color][/color].
On Thursday the 14th of May the [COLOR=blue! important][FONT=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif][COLOR=blue! important][FONT=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif]computer[/font][/font][/color][/color] was on and the power went out for approx 5 seconds. When it came back on the computer restarted with errors saying the [COLOR=blue! important][FONT=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif][COLOR=blue! important][FONT=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif]CMOS[/font][/font][/color][/color] clock had a problem and I couldnt go to any websites because the certificates were out of date. I checked the Cmos and fond the date reset to 2002. I correcter that error and looked over the other Cmos setting and found nothing wrong. I restarted and was able to browse once again but I noticed the fans were running at full speed all the time. Normally you cant even hear them.
When I tried to shut down the computer it seemed to shut down normally and then restarted 3-5 seconds later. This continued to happen so right when the next restart happened I held the power button in for 5 seconds and it shut down. Now the fans run full speed all the time and the [COLOR=blue! important][FONT=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif][COLOR=blue! important][FONT=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif]system[/font][/font][/color][/color] is very slow with an excess of hard drive activity and it must be shut down this way every time. Does any one have any suggestions please.
