Unhappy How to Fix Dead HP 6835 Desktop PC
Hi, I have a desktop pc HP 6835. XP Professional in it. No hardware upgrades. But it had downloaded all the normal XP SP1 pack stuff.

It was running fine, except I didn't use it much because of using a newer computer. It was always plugged in at first. Once every so often I would turn it on, and let it run a bit, to allow it to renew itself just by being turned on, but not online, I didn't want any more upgrades than it had so far.

Then one day it was thundering and lightning outdoors, so I unplugged it from the wall so it wouldn't get fried.

I forgot to replug it in for 3 weeks. When I tried replugging it in to the wall and it wouldn't turn on!

No clicking sounds, no whirrs, nothing, zip. Not a sound. It's just dead. I dunno why. I have a slight suspicion there's a possibility someone may have tried to use it and not knowing my password made it crash, too, but, I'm not at all sure if that's so.

The plugs all work, I checked the cable by using another cable from the pc to the wall, so its not just a bad cable.

The monitor still works on the same wall plugs, except it shuts down quickly because it's not getting any connection info from the pc.

I suspect it just might be that "CMOS" battery?? that maybe died because its so old, and not being plugged into the wall for so long, it couldn't recharge itself?

Anyways, that's all I can say. I would like to open it and try to fix it myself if anyone has any real tech advice on what might be the problem and what I should do to get it up and running again. I'd like to play my old games on it.

Thanks in advance.

Probably a bad psu is all if you have no signs of life like fans or lights. A cmos battery won't stop it from booting, just cause it to lose settings is all.

Power Supply Unit. (See, I had to google for the term.) I haven't opened it up yet, but, likely will, as I havent anything to lose. Is that the thing that usually looks like a grey box?

I suppose I'll see what the major electric cable looks like its hooked to, try to remove it and ask Circuit City if I can get a new one from them, then.

oh boy. (I know to a lot of people that might not be anything, but, all I've ever done to the inside of a pc is wipe some dust out of it a couple times.) Here goes....

Any more advice or links to picture how to's is appreciated,

Thank you again
