No POST, No BIOS, No Hard Drive activity

by TRIPLEJAY / September 7, 2008 12:04 PM PDT

About 8 months ago I built a new system with an ASUS P5E WS Pro MoBo, Intel E8400 3.0 CPU, (2) 150GB W.D. Raptors in a RAID 1 array, (2) 500GB Seagate SATA in a RAID 1 array, 4 GB Crucial Ballistic PC2 6400 DIMM, ASUS EN 8800GT TOP Graphics Card, Coolermaster 750 watt Realpower PSU, SoundBlaster Audigy 2ZS Platinum sound card (from previous system), 1 BENQ DVD R/RW, 1 Lite On DVD R/RW, (2) H.P. 22" LCD monitors, and I'm running 2 120mm fans - front and rear - and 1 92mm fan in the side panel of a Thermaltake Soprano case. This is a dual-boot system, with VISTA Home Premium 64bit on the Raptor array and XP Home on the Seagate array. Now that that is out of the way, on to my problem:
Last night I used my system as usual -- a little web surfing, answering/sending e-mails, and a little bit of CRYSIS and BIOSHOCK. I had no issues and the machine worked flawlessly. I shut down as usual via the Windows shutdown, and all was well. Tonight, however, was a different story which I don't understand at all. When I fired up the system I was unable to even reach the post screen which pops up prior to bios -- I got nothing, and the Hard Drive activity light on the front of the case didn't even blink. I restarted the machine several times and still got nothing. I removed the side panel and checked all connections - which were all fine - and I checked each hard drive and they were all spooling up, but still no activity light. I disconnected each hard drive one by one (which shouldn't make a difference with RAID 1 anyway), as well as each RAID array separately, and still no activity light. All I can think of at this point is that either my CPU or MoBo fried out somehow. We have had no thunderstorms or power surges in our area recently, and the system in on an APS surge protector anyway, so I don't think that is an issue. I am stymied, not to mention a bit perturbed, and would welcome and appreciate any help afforded me. Thanks in advance for any assitance.

Start as small as possible.

I would be duplicating all the usual you find on google with THE DEAD PC (use those words) but we start with no case, the PSU and the motherboard. We power up, we power down. 2 good (?) parts. Now we add the CPU+HSF and the speaker and hope it beeps in protest. If it doesn't we are looking at the possible bad parts.

I Started simple instead.

Don' ask me what the issue was (or still may be), but after reading your reply I looked at my system with dread, and thinking of having to tear this system down just to rebuild it again was depressing as hell. Not to mention that my workbench is currently occupied with another system I am building, and I didn't know where I was going to put all of those pieces/parts while I repaired this system. Anyway, I turned of the PSU and sat there in silence, staring at the machine and trying to brace myself for the task ahead. Then I thought "What the Hell- one more shot". So I turned the PSU back on, hit the power button, and Lo and Behold!! I heard the 'Beep' I have come to know and love and the system booted right up, no issues whatsoever. I've run a diagnostic check of the entire system, and everyting is perfectly normal and within parameters. I don't know what happened, but I'm also not going to question it at this point. Thanks for your prompt input though, it was much appreciated!

Parting thought.

I neglected one thing. When this happens, pull the AC cord, count to some big number and then try again. Sorry I missed that.
