Will you rate my PC advice? ("dead PC")
Posted on 2006-06-01
I hope you guys don't laugh too much at this. I'm a novice PC tech who makes housecalls at a very low rate for my area. I was dealing with a "dead PC". I expected to find that either the PSU or motherboard was dead. But both appeared to be dead. (see below) Normally I would have spent time checking all the jumpers & other things (see below), but the user wasn't there to authorize that kind of time. Plus, the PC had not been opened since sent from the factory, so the jumper issue seems moot. The user had unplugged and replugged the PC when the monitor was "flashing something wierd". (side question - Is it common that BOTH PSU and the MoBo will be damaged?)
Does anyone want to take a quick look at the following and tell me (briefly) if I made a reasonable recommendation?
Problem: "Bluto's" PC won't power up. The fans (board and PSU) never move. The fans never moved in any of the scenarios below. Assume when I "swapped PSU's" I connected all the power cables correctly, altho it only took P1 and P8 (next to cpu) to get the fan turning on the good system (Popeye's).
"Popeye" is Bluto's sister and lives in the next room.
Reccommendation to user ("Olive"):
Since Bluto's PC and Popeye's PC are both Emachine T2682's, and Popeye's IS working:
I swapped the Power Supplies (PSU) and power cables and powerstrips between the two PCs. [Both powerstrips were powering other items - I used plugs that were were hot / powering other appliances.]
Popeye's PSU worked only with Popeye's PC.
Bluto's PSU didn't work with either PC.
(1) Bluto's PSU is bad/burned out, and
(2) ONE of the following is true:
--(a) Bluto's motherboard is also burned out, OR
--(b) Bluto's motherboard needs to have something changed, e.g jumper cables have to be moved around, or the start button replaced, or there's a bad component (ram, cpu). [EE -- I couldn't find a cmos battery...] But to check those I'd need to get the diagram for that motherboard, switch PSU's again, and try switching those around.
BUT -- since the problem started WITH an electrical event and WITHOUT anyone opening the PC, and since there's not warning beeps at all to suggest things are wired wrong or there's a bad component, (b) is unlikely.
If it's under warranty, send it in.
Otherwise, it's up to you whether you want to
(i) pay someone to find the motherboard diagram and PC documentation online and check for jumpers settings or component problems, or
(ii) buy a new PC, or
(iii) buy a new motherboard and have a tech guy install that (in order to save/salvage your memory, HD, cd burner, dvd player, cpu, cpu fan, PCI cards and pc case).
In my opinion:
(i) and (iii) would take a few hours at least, and are fastest done in a shop.
(i) might not cost you any parts, but would cost labor. And it might simply prove that the motherboard is bad after all.
(ii) would cost the a new PC.
