Dell E1505 not booting: suspect dead motherboard

post #1 of 5
Thread Starter 
After a night away from town, leaving my laptop on as I usually do, came back to find a black screen with computer still running. I suspect Windows Update ran and had trouble with something. Powered off, turned back on, and the startup hung as the OS was loading. Safe mode said the hang was at crcdisk.sys (I searched for this on the internet, but was not able to do much with it, as will soon be seen). I got my Vista installation CD and tried to boot from it, but it would not -- not even if I removed the hard drive from the computer. A friend had a similar laptop, and we exchanged hard drives; his would not boot in mine, but mine would in his (all data intact). I tried reseating the RAM; no good. Another friend lent me a Ubuntu boot cd, which also did not complete loading. Long story short, I can't get anywhere where I can do anything meaningfully useful. I can't get to a command line to run chkdsk, or to the internet to flash my BIOS, or to a text editor to write papers for school. The people I've talked with say probably the motherboard is bad.

I was able to get to an unhelpful IT fellow for a few minutes, and he was able to boot Windows 98 from CD, but he didn't let me do anything, or have the CD. I'm going to try to find one and see what I can do from it.

The questions I have:

Is it worthwhile to shell out for a motherboard? Would it be better to get a new laptop and transfer data?
Is it possible that only the BIOS chip is bad? Is it possible for me to just replace it, leaving the rest of everything in? Do I have ANY other options?
If I do get another motherboard, what sort do I need? Is it sufficient just to look for the exact same sort as I have? Is there any way to get one cheaper? I think I have a video card in there -- never really use it...
Anything else you can think of letting me know?

Thanks so much, y'all...

You can test for the problem by running the board's built in diagnostic. Power down the system and hold down Fn on the keyboard while powering up. It'll run a basic test of CPU, memory, and video.

Holding down Fn during boot creates no noticeable effect...however, I can run the diagnostics from the F12 screen that comes up during boot. These show no errors across all tests.

I would first try to reseat the ram modules, swap them around or take one out one by one if you have 2.

cheers ...

Did you hold down Fn before and while you were pressing the power button?

It really doesn't sound to me that your problem is with the motherboard, but with a combination of Optical Drive and Hard Drive. Beleive me, I did have a customer who once had both a Defective DVD-RW drive AND a Defective Hard drive AT THE SAME TIME. (DVD-RW could only read CDs, not DVDs which is what XP Media Center and Vista all ship on.)
