something must be failing?

ok so, a couple of weeks back the pc started to flash up error messages on boot. such as

- bootmgr is corrupt system cannot boot

-a disk read error occurred. press Ctrl+Alt+Del to restart

- (block of text) status: 0xc00000e9. info: an unexpected I/O error has occured

- BSOD - stop: 0x0000007B (0xfffff880009a9928,0xffffffffc0000034)

-the file is possibly corrupt. the file header checksum does not match the corrupt checksum

BSOD - stop: 0x00000050 wimfsf.sys



these have now STARTED APPEARING AGAIN

to try combat the 1st time. windows 7 64bit was reinstalled (100% clean) over 20 times. that failed.

so we bought:
a new hard drive
connectors
brand new version of windows 7 ultimate 64bit.
new CMOS battery

these have not helped.

but what i dont get is why. if i load up and do a memory diagnostic upon restart it works fine. once it is on a restart will work. a shutdown followed by IMMEDIATE turn on will work, but if its shut down and left for like an hour its back to the errors.

in my opinion, i think maybe the MOBO is failing in some way?

am i right? wrong? you have a fix?

please any help will be appreciated

Thanks for filling out your Specs so well! DELL PC's generally have a built in diagnostics, I suggest you run these, I think it's available by hitting f8 prior to the Windows 7 screen coming on. Pay special attention to the RAM tests, you either have a stick of RAM going FUBAR or Windows 7 is not happy with where your RAM is on the mobo I'll do a little digging on your system.

What motherboard are you using?

Is there by any chance a BIOS update available?

There are a few updated bios versions available ASUSTeK Computer Inc.

After a quick read there was a revision that fixes system stability.

On the page link I gave you, click on the download tab. Select your OS and the downloads will appear. I would try updating the BIOS to see if that stabilizes things.

Uh, the OP has a DELL not an Asus, the last BIOS update for his PC was in 2007, it shipped with an XP OS and he states he is loading Windows 7 64 Ultimate. His PC is Vista 64 capable so I think W7 64 is fine.

JTHEWOLF,
Your original spec's at DELL state the PC was shipped with 2Gb RAM and you show 4Gb, if this is correct did you simply add additional RAM or swap it all out? If you swapped it out do you have the original 2Gb so that it can be placed back in that configuration to test further?

I read the wrong specs. I thought I was at the top of the page and read into TVeblen's specs.

TVeblen was on to it and informed me about it. My appologies.

No apologies required, your advice was sound, and applicable, if the OP had an Asus, just wanted to point out it wasn't in the off chance the OP saw BIOS was available etc.

JTHEWOLF, which did you run - Windows, Dell or a 3rd party memory diagnostic test? I seem to recall Dell system diag's are fairly comprehensive, but can't vouch for memory tests (this far on from owning one). I have absolutely no confidence in Windows mem' diag' so, if that's what you're relying on, may I suggest you try the free Memtest86 (or the + version) or Memscope so see whether your memory really is good.

I'd agree wholeheartedly with you if the OP could get his system into Windows 7, the error he's getting means his system is incapable of booting past the error which is why I suggested the DELL diagnostics.

His system is also out of warranty and if he does need something other than RAM to fix the issue the diagnostics codes should help pinpoint the problem.
