One of my first jobs was tech support while I was in college. We supported the local community free of charge for work experience etc. So my second week in, I get the following customer. If I hadn't seen this firsthand, I wouldn't have believed it.
<me> Thanks for calling <college> technical support, how can I help you?
<user> Hi, I have a problem. My computer won't boot up.
<me> It won't boot up huh? When you power it on, nothing happens correct? No lights, no nothing?
<user> Yeah, it was fine this weekend but now it just won't start up. I don't know why.
<me> Have you experienced any blackouts, brownouts, power surges, anything odd this weekend? Or, has anyone else used the PC since you last did that you can think of?
<user> Nope, just me.
<me> Ok, what was the last thing you did on the PC? Did you see any odd behavior, error messages or anything like that?
<user> No, everything worked fine. I didn't get any errors or anything. And it shut down just fine.
<me> (thinking he is trying to use the monitor to turn on the PC) Ok, humor me for a second, it's the case itself and not the monitor you are trying to power on correct?
<user> (laughs) Yeah, I made sure of that.
<me> (laughs) Ok good, are you close to the office here? Bring it on down and I can take a look at it for you.
<user> Yeah, about 5 minutes away or so.
<me> Great, if you don't mind, bring it on down and we'll check it here in the shop.
<user> Sure thing, I'll be right down.
10 minutes later in comes the customer with his kid and PC in tow.
<me> Ok, let's fire this up and see what we get. Do you have a warranty or anything that might be affected if we open the case up?
<user> No, go ahead and do what you gotta do.
So I crack the case on his Gateway (ugh) and check to make sure the hardware hasn't had "chip creep", is all connected, hasn't had someone monkey with it etc when I all the sudden see the problem...
Just behind the back end of the CD-ROM, all over the back of it and on the motherboards' upper right side is a brown smear, like liquid hit the CD-ROM and motherboard or something then traveled down the board til it met the RAM sockets.
<me> umm, excuse me sir, has the PC had water or any other liquid on it recently? Like maybe someone spilled something?
<user> nope, I ALWAYS use the (and to this day, 10 years later, I STILL can't believe he said this) cup holder for my coffee cup but I did put my travel mug on top of the case for a minute cause I bumped it and it spilled a little.
(It turned out he had a 16 oz travel coffee mug, which fits perfectly in the tray of a CD-ROM drive, imagine that...)
<me> Ok well, here's the problem sir. When the coffee mug was in the tray and you jostled it, the liquid got in the CD-ROM tray and, when you closed the tray, that damaged the CD-ROM. It's actually not a cup holder. Then, when you moved the coffee cup to the top of the PC, there was still coffee on the bottom of the cup, it appears to have leaked into your case and onto your motherboard (I showed him the brown smear on the CD-ROM and MB at that point). Bottom line, the coffee appears to have shorted the mainboard or power supply out and there isn't anything really that I can do here for this PC.
<user> So you can't fix it?
<me> Ummm, well, we can replace the motherboard but since the liquid shorted it, you will probably need to replace the memory, video card, etc etc.
<user> How much would that cost?
<me> Frankly sir, a hell of a lot more than just buying a new one.
<user> Well ****. (laughs) I guess I learned the hard way huh?
<me> I'm afraid so sir, sorry I couldn't help more.
