I'm not having a good week with computers. Last week, I RMA'd my 7900gt since it was defective, and in doing so I lost my main system as I have no other pci express video card to use in the mean time. So I grabbed my daughter's Dell, a pc who's 6600gt died last week as well, and was making due with it the past few days. It could play WoW for my wife decently (Radeon 9550) and was generally doing OK other than the firefox windows that kept opening up (like popups). It hadn't been on the web in a year or two, so I figured it needed some windows updates to fix that annoyance.

So I go to the windows update site, download/install the 52 critical updates and then restart the machine. I was greeted by a BSOD. I started it again, same thing. I can see the Dell splash screen, but afterwards it just goes to a black screen with only a flashing cursor. No error messages at all.

I tried using f8 (and f12 like the splash screen says to use) to reach the boot menu and start in safe mode - that wouldn't do anything either. In fact after pressing f12 the first time, it said "keyboard error" After that, it would only beep when pressing f12, restart or not. I then tried to enter the bios, I press f2 and see the spash screen indicating it's "Entering Setup..." and then it again brings me to the black screen. I tried another keyboard and got same results (one was ps/2, the other usb).

I tried pulling the ram and using a stick at a time, I also moved the jumper on the motherboard to clear the CMOS (or whatever it does). I tried another video card as well as pulling every unneccessary peripheral from the machine. No change, still black screen. Disconnecting the C: drive at least gave me a no drives error message, followed by the flashing cursor of death.

I can't imagine the windows updates could cause me this much grief, could they? I figure it's coincidence. Prior to this there was no indication of any problem whatsoever. Any ideas?

specs: 4 year old Dell Dimension 4550 Pentium IV 2.4GHz 1gb Kingston pc2700 (2x512) Some junk OEM Dell motherboard Soundblaster Audigy ATI Radeon 9550 256mb AGP FSP Group 450w PSU Windows XP Pro sp2

Assuming it is a bad board, I thought this would be a good opportunity to update the machine a bit with a cheap board and cpu. This board would also allow for the transition away from AGP. It will utilize all the parts above with maybe a better AGP video card like a 6600/7600gt. Does this list below look OK?

AMD Athlon 64 4000+ San Diego s939 Processor $59.99 I'm not worried about the dead socket as this is a stop gap solution.

ASRock 939Dual-VSTA ATX Motherboard $66.99

Linkworld ATX Mid Tower Computer Case $27.99

Total: $154.97 (w/ shipping= $177.29)

have you tried entering your bios? It could simply be a fried bios chip, which could be replaceable and save you a few bucks. Try calling Dell and see if they will help at all

If its a fried BIOS chip and the PC is still under a warranty from Dell they will replace the entire motherboard. Still worth a shot especially if you bought an extended warranty thats still in effect.

One of PCs did the same thing. just try taking out the battery or jumper for the BIOS and it will reset it (the bios). if that doesn't work, try putting the PC out on side of the road and have some herbal tea!!

if you installed any new chipset updates that Microsoft has happily put in there CRITICAL UPDATES, then call DELL and they should fix it.

I've gotta believe that it's more than a coincidence that this happened right after he applied the Windows updates...

That may very well be what happened.

I did try swapping the jumper already, but I haven't tried pulling the battery out. I'll give that a shot this morning and post back.

I'll also try giving Dell a call, though I don't believe I'm under warranty any longer.

btw - To be honest, I don't really mind if I have to get a new cpu/board as this rig needs it anyways. This may finally be my excuse to force the issue. That said I hate not knowing for certain what happened. :Puzzled: Thanks for all the input everyone. :smokin:

Are any of the capacitors leaking or look " rusty" on the mobo ?

~Merrick - I was just checking the capacitors and the motherboard in general again, and all looks well. No leaks, discoloration or burnt areas. While doing so, I popped the battery out for a minute...

Huh. So something as simple as popping out the battery seems to have fixed the issue. I just did that and it finally let me get into the bios, and upon restart it started loading windows.

I feel like a bit of an idiot for not trying that before posting my tale of woe. Lesson learned. Thanks again for all the suggestions everyone.

P.S. - Our friends at the big M never cease to amaze. It seems ridiculous that a suggested update could essentially kill your pc. Good thing there's forums with helpful people around.

well always remember. An update can cause something like this to happen if it changed the parameter of a driver.

BUT, you may want to change that battery out for a new one. One last thing, the capacitors have been known to bleed through to the back of the board, so having a case where both sides pop off is a good idea.

Glad the forums could be of some help.
