My Computer Is On Fire!!!

post #1 of 9
Thread Starter 
Now that I have your attention, I will tell you what happened.

One day 2 weeks ago, I left for a class and came back to find that my PSU is dead. It seems that 350-watts is not enough to run 2 hard drives, 2 optical drives, a floppy, 2 nic's, a USB2 PCI card and an ATI Radeon 9800 EZ. This was at night, so I borrowed a friends old, loud, dirty 400-watt PSU for the time being. The next day, I quickly purchase a new on on Newegg.com and had that shipped to me ASAP. Popped the PSU in and my computer starts. "Yes", I say to myself. But then it shuts off. Completely off. I have to unplug the PC and replug it to get it to start again. The cut-offs seem to be random and I have had it cut off during bootup, after bootup just finished, when I tried to play a particular video file, 2 more times doing random stuff, but never during the 5-hour GPU benchmark or 4-hour BIOS benchmark (left it on temp monitor screen). Question #1 is what is wrong with that PSU?

I cant be without a PC, so I decided I will RMA the PSU whenever I had a chance and popped the borrowed PSU back in. Everything goes fine until this weekend. I went away this weekend as I have done for the past 30 weekends leaving my computer on (I run a server). I have left my PC on 24 hours before, but this time I was not at it for a full 2 days. I come back and all the lights on my devices are out (no mouse light, no kbd light, screen is off). I figure this was just a really odd crash and I press the reboot button. Everything is fine, passes the Windows load screen fine. Right after that, my PSU seems to go crazy and spin into overdrive, then even higher than that. The fan returns to normal as all my devices cut out again, and this time I decided to unplug it. I step behind my PC to smell something burning (that wierd 'technology-is-burning' smell) nad I quickly yank my power cord out and all cords to the tower so I can get inside to see the damage. There are no physical damage to the PC that I can see (and I cant see inside the PSU). Question #2 is is my PC completely toast or is it just the PSU?

Right now it is sitting on my floor, open (but covered) and the old, borrowed PSU still connected. It has been like that for 19 hours. All PSU's mentioned are in my possesion.

Thank you for your time.

i would think you have defective psu. I would suggest to plug up the old psu and see what happens, if all is well I would leave on the desktop for awhile to see how stable it runs, to make sure nothing trully died in the process of. But rma the newer psu to get a replacement.

Ok ... I think I have more bad news ...

I got a new PSU from CompUSA today, took out the old one (PC never was plugged in since incident) and popped the new one in. I turn on the computer, there is no confirmation beep and all the lights on the keyboard flash. The hard drive status light, which usually turns on also, does not come on at all. What is wrong with my computer now?

(I have a sinking feeling its a fried mobo, cpu, or both)

Well, if nothing is comfirming it's readiness, so no beep, lights whatsoever, it usually is the motherboard and/or CPU.. But optical drives should work nonetheless.. So when you start, you should be able to eject the tray. If that's also not possible, something is seriously wrong.
In case you have troubles with your PSU, which could be caused by a faulty power outlet in your wall, unlikely but still possible, borrow an APC. Filters the and stabilizes power flow.

I can still use the optical drives, the hard drives seem to spin up fine, all the fans are in working order, but the only lights onis the flashing keyboard lights and the power light. Only that and physical movement notifies me that it is on.

Yep. CPU and/or motherboard are done for.. Only other explanation would be that you didn't connect the power cord properly to the motherboard.

What kind of motherboard do you have? Some mobo's have a tiny light bulb that lights up to let you know there's power. Try booting with the basic componets: CPU, mobo, RAM, etc, and see if you get any beeps or whatnot. Don't connect the unnecessary stuff like extra fans, floppy, or optical drives. Also I'd take the processor out and check for any physical damage .
