Computer gave blue screen, and froze a couple of times, rebooted a couple of times and running fine again. I checked inside and found a small capacitor had popped on mainboard. It's a Core2 Quad Socket LGA 775 and a intel mainboard. Voltages are all correct in intel desktop utilities app. Is it safe to run it like this till I get hold of new mainboard? I know the mainboard might stop working altogether, but it's going to be replaced. I'm worried something else in pc gets damaged. |

Did something else pop ?

If its running the and capacitor has blown you risk long term damage to the rest of the board. I have replaced dozens of blown out capacitors on electrical items including motherboards and graphics cards ,Its very easy and capacitors are cheap as chips

he asked nearly a year ago, I think it's taken care of by now

yea if the cap has blown it stores the juice like a battery n will chain react

capacitors stores a certain amount of electric at a governed voltage, it will be marked on the capacitor like 35v and 200farrads etc etc. Running with a damaged capacitor means if the computer requests an extra boost of power, say when a fan winds up to speed, it comes from a capacitor. the stored energy is released, but the meantime the capacitor then fills back up.

Actually I'm still running the computer to this very day. Lol. It gives problems every so often. Drives have been clicking for almost a year now. I'm betting they are damaged from the problem with capacitor. When it finally all dies, if it ever does. I'm thinking I'll just have to get whole new computer

I'm only using laptops these days, but in the past I had to change a capcitor on my desktop.....NEVER try to desolder it.....the board is multi-layered, and too much heat can cause all kinds of problems....I used a side-cutter, and gently clipped away at the damaged cap...then I resoldered a new one onto the legs of the old one....

Cheap or improperly filled caps tend to burst at the top.....I used to give my mainboad a gentle dusting with a soft paintbrush, and inspected the board at the same time....

When it comes to electronics, I never solder anything without using heat sinks. Surprise, heat sinks have been used for soldering long before computers came around.

I have desoldered hundreds of them , with the right gear its easy . |

@ norega - 24.08.15 - 06:01pm What are you talking about This.  Motherboards have metals that can melt when exposed to heat from a soldering gun, so you clip these on to dump the heat before it reaches something fragile. Soldering has long been used before there were any electronics. Take copper pipes for example, you also used heatsinks so you wouldn't risk setting anything on fire. |

Take copper pipes for example, you also used heatsinks so you wouldn't risk setting anything on fire. on modern computer motherboards and electronics in general these are not needed . The pcb's in modern electronics are upto 20 layers thick with a solid sheet of copper for heat protection . Plus modern components can withstand heat 10 times what a solder iron can output |

What they say and what is fact can be two wildly different things. It always pays to take an extra step so you don't end up blowing the cost of a replacement motherboard.

Ok, so what is wrong with the way i do it?....i simply prefer not to desolder it, cos why take any kind of risk?... |

I am not saying you are doing it wrong, I just take extra steps as insurance. Since I do not have extra money to throw away on my screw ups, it just gives me peace of mind.

Modern motherboards use solid caps with 10-20 k life

dont keep using it it will make more dmg in the long run that compositor is now just a wire pretty much or and most the volts will just bypass that path to another easy path making that1 take more power then should by it blowing it up its alrdy put a strain on your chips any way might not seen by the eye but some things just need the smallest ESD to fry it just remove it an replace it its only a 5min job 30 an capacitor are cheep or just hold out the few days till replaced
