One day while having my computer on, the power for the house went out. After the power came back, I proceed to turn on my computer.....nothing. All the fans are running, but nothing shows up on the screen. I tried it again. First all the fans started to run, then the DVD drive clicked as usual. Then the video card fan runs at full speed. That's it. I RMA my motherboard and video card already. Any clue guys? Please help. Been out of my desktop for two months now. I'm dying.

It's probably the powersupply. When your house gets hit with a power outage it can fry all sorts of junk. Usually when the power comes back on, there is a surge, and that wipes out PSU's all the time. Surge protectors will not stop this. The only thing you can do is buy a battery backup system to block it or unplug your machine. Even though your computer may not be on at the time, it is still at risk.

Sorry dude, but that sucks. Try swapping the PSU if you have one handy, or bum one off a buddy. I'm quite certain it's the PSU. Try RMA'ing it if you can or send ot back to the manufacturer. Hopefully it's still under warrenty.:(
 
do you have a led bracket hooked to the motherboard?look at it,if you do have one,and try to determine where in the bootup process you maybe having trouble.or, does the machine emmit a series of beeps.try removing components and see if any thing happens.
 
Thanks for the reply guys. I'll try to RMA the power supply. I guess I'll have to invest in a UPS system.

No, the motherboard doesn't have a LED onboard. I have try unpluging my harddrive, memorys, and DVD drive, same thing. No beeps.
 
I'm not saying you have to buy an UPS, but if your power is going out all the time, you may want to invest in one. Most of he time if you do have a surge, only the PSU dies. Sometimes the mobo gets wacked too. Hopefully, the mobo you already RMA'd did not get zapped again when you installed it into the PSU in question.
 
well, just borrowed my friend's power supply. Did the same thing. So I guess it's not my power supply. The only thing left to check is CPU, and Memory. Would a bad memory do this, where it wouldn't even post?
 
Have you tried clearing the cmos? Sometimes even a new mobo needs a cmos clearing to get it to boot.
And yes bad memory can stop a pc from posting, but usually you will hear loud beeping. If you can, try a stick of memory from your friend to see if you can get it to boot.

It's not likely that the cpu is the culprit, but it is possible.
 
Yeah, I did clear my cmos. Funny thing is that none of my friends uses DDR2. They are still using the good old AMD Athlon. What do you guys think? CPU or Memory? or other??
 
I'll try that. I was dreading this cause I have the ultra-120 Extreme which have a back plate. No avoiding it.
 
keep us posted.
i am curious to see what the reason behind this is too.
i too am experiencing the same issues.

i rma'ed my power supply and will try that next week...
if that doesn't work, i guess it ram or cpu for me too.
 
I have no idea now what the problem might be. I might just take it to geeksquad to take care of it.
 
Maybe one or more of the rails on the PSU got damaged. Try switching your current components with other working ones until you identify the problem.
