Power on, no post. Any ideas?

Hey everyone,

I've got a problem with my computer and I am hoping some of you experts could shed some light on the problem. Thanks in advance for the help.

I powered down my computer and the next time I tried to turn it on the power came on but nothing happens. To explain things further when the power button it turned on all the lights, fans, and peripherals power up but I dot NOT hear a post beep and my CPU fan begins to spin much faster than usual.

These symptoms make me believe either 1. my PSU is failing, or 2. my CPU craped out on me. Possibly my mobo?

My hardware is as follows:
--ASUS P5N32-E SLI LGA 775 NVIDIA nForce 680i
--Intel Core 2 Duo E6750 Conroe 2.66GHz
--OCZ GameXStream OCZ600GXSSLI 600W ATX12V
--Western Digital Raptor X WD1500AHFD 150GB
--Foxconn FV-N88SMBD2-ONOC GeForce 8800 GTS 640MB
--Patriot Extreme Performance 4GB

Any suggestions or ideas about the problem would be greatly accepted! Im at my wits end and I would just like to finish my research paper .. and play some TF2 ;-)

Thanks again for any help!
 
Is the interior clean, the CPU heatsink fins?
I assume XP did you try Safe Mode?
Check (reseat) all internal connections.

You wanted a responce, it does not sound good. Install the HD as a slave in a different PC to complete/safe your info.
 
I have the same issue. I bought a new PS and tried to reboot with only one stick of memory at a time to make sure I didn't have a bad stick but unfortunately it wasn't either one of those.

I never got the beep or post. My monitor wouldn't even come to life.

I would think if it was the HD you would still get a beep and a post saying that a HD was not detected.

I just ended up ordering new components and starting fresh. I was due anyway.

 
Thanks for all the replies. Here is an update on the problem .. it has manifested into something else now and I am even more confused.

I stripped the whole machine down and rebuilt it with all the same components. Once I was done it started right up .. pleasantly surprised but kind of perplexed I just watched as it booted past the bios but then I received a "DISK BOOT FAILURE, PLEASE INSERT THE SYSTEM DISK" message. The bios recognizes both my primary and secondary HDD, and my DVD drive. All three of these drives are on the SATA controller and the primary HDD with the oS is new.

What is strange was I was receiving this error several several weeks ago. It would come and go, let me boot or stop me with this error so I swapped out the HDD and it began working. Now I am getting this error again on this new HDD.

The CMOS were cleared and SATA cables changed out and I am still getting the error .. any more ideas guys?
 
That sounds like either the CMOS battery is going dead and not retaining the settings or the main hard drive with the OS on it, is starting to fail.
 
Not likely the battery or the hd.

Dead battery would generate a "checksum error"message. Would be odd for 2 hds to fail so soon (unless psu is really undervolting).

Try different cables on the primary drive (swap with another drive if you have no spares).
 
Yes, I missed the note that the OS is on a new hard drive. But I think it can still be the battery causing the cmos not to retain the settings. Cheap to try it. If not, then maybe the cable as you say, or if the drive controller is on the mobo, it may be going or gone bad.

That's my guess. I've actually had that same thing happen to me, although it was many years before SATA was developed. It still wouldn't hurt to spend $2 on a new battery, and 2 minutes to install it, though.
 
When I was trying to clear my CMOS through a jumper swap I received the error "checksum error". Is that a defiant sign that the battery is starting to die?

I think I am def going to buy a new battery today and see if it works. Thanks for all the help guys.
 
If that doesn't fix it then it's time to get a new motherboard. Which might become an expensive ordeal. If it's just a simple machine I'd get a Dell Quadcore prebuilt machine and slap on a 9600GT for $100 and you're ready to rock.

This happens to me sometimes when I reboot. I don't know if it applies to you but when I reboot sometimes it'll try to boot off of one of my IDE drives when it should be booting off SATA. I sometimes have to unplug it and replug or sometimes I can just go into bios and force my IDE drives to slave.
