Please help, I am having the craziest of problems. I built this system about two years ago so i know the ins and outs of it. Here are the specs...
Asus P5N-e Sli Motherboard
Intel E8400 Wolfdale
eVGA GTX 260
Corsair 2 x 2Gb Mem
Antec 550w PSU
2 500gb Drives in RAID striping
Win XP SP2
This system had been running strong for a little over two years with no problems. About two months ago I started having some problems booting. It would load and log in to windows, but there would be about a 30 second lag until I would actually be able to do anything. It really didn't bother me it was just a little longer to boot up. Then it got weird...
One day my system would just not boot. It would run fine through the BIOS POST but then when it comes time to load windows all I get is a black screen with a flashing white line in the upper left corner. I have waited several minutes to see if it will load and it will not.
At first I thought it was the power supply so I tried a brand new one and I have the same problem. I tried swapping the memory modules around/only using one, and running a mem test and that doesn't work. I have tried clearing the CMOS to reset the BIOS settings and that doesn't work. I have checked my RAID utility and it sees both of the drives and tells me that they are healthy. I have tried a different video card.
And this is really weird! I can see all my drives in the BIOS.... but I can't even load windows from cd/rom! I have checked/changed boot priority in BIOS and still the same problem.... After BIOS POST, it doesn't load windows, all I get is a black screen and a flashing white line.
In my opinion I have sufficiently narrowed this problem down to either the motherboard or the cpu. Can I get some other options/opinions on this please? I have priced out a whole new system on newegg but I would rather just get this one back up and running.
Well in reading I too would have done the same exact steps and I too would have initially concluded a failed PSU. I assume the replacement is/was at least 450W+.
When it comes down to the brass tacks - 80% MOBO and 20% CPU.
However, before ass-u-ming either I would do a full breadboard, I've seen shorted a shorted mouse and even a bad fan cause a problem.
You can try Lazyman's Breadboard -
* Disconnect ALL Front Panel & USB Headers ; keep only the PWR & Ground <best> short w/wire.
* Disconnect ALL peripherals including the Keyboard/Mouse
* (1) Stick of RAM in the second DIMM slot from CPU
* Unscrew both the MOBO and PCIe screws
Pull the MOBO away from anything conductive and supported by a towel ; short PWR & Ground to start.
So to understand, you get the (1) Beep and are getting NO e.g. BIOS/MOBO 'Splash Screen' - IF that's the case then I'd look at the GPU and Monitor and Cabling/Adapter.
IF you're seeing the Post 'Splash Screen' AND trying to Install Windows then: 1. HDD must be free of another OS, 2. ODD (DVD Drive) is not compatible. In the BIOS you can try both SATA -> AHCI and SATA -> IDE. Try a different ODD.
Then as I stated the problem is more than likely from the ODD. IMO - get a new e.g. $20 ASUS SATA DVD drive. But, first in the BIOS make sure the 'current' ODD is in the #1 Boot Priority position. There's also a small chance the Windows OS DVD is damaged.
Bad vs Unsupported. Typically 'IDE' drives are more a problem than SATA (ODD or HDD). I assume the ODD is a SATA type and not IDE. If using IDE drives then both the BIOS and drives must be setup correctly for Salve & Master; Review page 1-30 'IDE Connector' of your manual for proper connections.
