Brief History -
This computer was bought in Late October of 2009 to replace a laptop that had blown up (Dell seems to be useless when it comes to support) and I needed a replacement computer for Finals. I had bought the Computer and Video card at the same time and used them both with the stock power supply. I had some video freezing issues, but found out that i had forgotten to disable to integrated graphics card off in the bios, so that problem was resolved. I had no issues with the computer till a few weeks ago, when my sound was not being detected by windows. I ended up having to reinstall the sound card every time i started windows. This brings us to now.
My computer is sometimes able to boot off of the hard drive (5% of the time?), but usually is unable to detect it or when it does detect it i am given a fault hardware error. It is able to see the DVD drive fine. The bios is detecting the hard drive in the BIOS settings, but still will not boot from the hard drive.
Basically -
1) The BIOS is able to detect the hard drive, but cannot boot from it.
2) The post works fine most of the time, but sometimes freezes or lags when it gets to the drive detecting part.
3) Able to get into windows some of the time and the computer usually runs fine.
4) When it is able to detect the drive i get a SMART error for that sata port the hard drive is on, but not the one the DVD drive is on.
Things i have done -
1) Thought the MBR was faulty - booted off of recovery CD that windows 7 can make and didn't find the drive. When i was able to i did a memory scan and a hard disk scan. Had no issues with either of those.
2) Restored BIOS to defaults - Did not work or affect the problem in anyway.
3) Updated BIOS - did not work or affect the problem.
4) Tried a different hard drive - BIOS saw the hard drive, but was unable to boot from it or see it using the recovery CD.
5) Tried the hard drive in a different computer - Computer was able to view the hard drive.
6) Replace the hard drive cable - did not work, tried it in another computer with my current hard drive and didn't work.
7) Replace power supply - Did not work or affect the computer at all. Bought a new case with it and everything got reseated.
8) Reformat computer after backing it up - Looked like it worked for a few hours, but when shut it down for the night wouldn't boot up in the morning.
9) Switch Sata ports on the motherboard - Able to find the dvd drive most of the time (95% of the time?), but was able to detect the hard drive more often(Some ports don't detect the hard drive, but the bios will view it under the bios settings) and able to boot off of it (5% of the time?) off of 2 of the 6 ports.
When i moved everything over to the new case everything was reseated and it was a normal installation of a computer. I am unable to think what it could be. The motherboard is posting fine usually and is able to detect the hard drive in the motherboard settings, but cannot boot or access the hard drive most of the time.
