Greetings; This is my first post on this forum, so I'll be as concise as possible. My system specs are as follows:
Coolermaster Centurion 5 case
Antec sp 500 PSU
Corsair twin x ddr 400 memory-2 x 512meg
Asus A8n-Sli Deluxe MB
Opteron 170 cpu
Asus Geforce 7600 gs video
DVD-rw drive and floppy drive/card reader combo
I built this system and have had it running well for about 1.5 years and recently after cleaning (blowing dust out of case), My system failed to start up. I checked reviews for psu (which where very positive at time of purchase) from Newegg, and I discovered that quite a few of these had failed within the same time period as my purchase. I contacted Antec and they informed me that they had discontinued that model, and much to thier credit they promptly sent a replacement. The replacement is a Neo HE 500 watt.
Ok, so I replaced the psu and started my system up with no problem and everything seemed fine. I went into bios and set it up as it was previously, (overclocked to 2.8 ghz @ 1.4 volts prime stable). Everything seemed fine and I ran some bench marks and did some work (estimating and bookeeping) the rest of the day and shut it down for the evening. Next morning, I pushed the power button and lights came on briefly and fans started to turn, then shutdown immediately. I tried this several times (5 or 6) and finally it stayed on. However, when posting, it said "checksum error, defaults loaded". I continued to bootup at default settings and everything was fine albeit much slower. I then restarted and set up bios again as I had it previously and continued bootup and again, no problems. I seem to be able to restart at any time and it boots right into Windows with no problems, however the problem happens every time I shut it down completely and attempt to start up again, multiple times of pushing power button before system will power up completely and then it starts with "defaults loaded".
My question is could it be a problem with the new psu, the power switch or something else? I have checked all mb connections and reseated cards and memory. And why would it continue to load defaluts when finally staying powered up? Any ideas or suggestions would be greatly apprediated.
