I was using my PC about two weeks ago when it simply stopped. No errors, no noise, it just stopped. The keyboard and mouse ceased to work and it just sat there glowing at me contentedly while I scratched my head.
I powered the machine down and brought it back up and received the famous "No system disk" message. I rebooted again and got into the bios and saw that my hard drive was no longer listed. Working on the assumption that the drive was bad I dropped in a known good drive and had the same results. It wasn't found.
I then changed out the SATA cable, nothing. Changed the power cable, nothing. Tried all the SATA ports on the motherboard, nothing. Then I started to move out from the HDD to other components on the off chance that they were some how causing the issue. Reseated the RAM, changed out video cards, unplugged CD-ROm (which has no issues running CDs and working as the boot drive), etc. Each was done singularly and each time there was no change.
Reloaded the BIOS defaults, nothing. Popped the battery and waited 10 minutes and reseated it, nothing.
At this point I'm confident in saying that the motherboard has died on me however I'd like some second opinions before I spend money on new equipment.
My specs are as follows.
ASUS P5N72-T Premium
Intel E8400 3.0 Ghz Core 2 Duo (not overclocked)
8 gig DDR2 800 Mhz RAM
Hitachi? Deskstar 260 gig HDD (drive that was originally in it)
WD Velociraptop 160g HDD (know good drive used for testing)
EVGA Geforce GTX 460 1gig (factory overclocked)
Any thoughts on the matter would be appreciated.
