Hey guys, I've been having a problem with my computer and any help would be greatly appreciated. I shut it down yesterday for a couple of hours and then when I tried to reboot, I kept on getting a checksum error. So I looked around and followed the advice from this thread: http://www.hardforum.com/showthread.php?p=1029193094#post1029193094

But now it's even worse; I checked the CMOS battery and replaced it with a new one, but now my computer won't even power up at all. I do have power to the motherboard (Asus A8N-SLI Premium) and I checked that the power switch wasn't broken (I shorted that jumper to see if the computer would turn on, it won't). Now, I'm confused about what I can do to fix the problem. Is my motherboard just dead or is there something else I need to try? By the way, I have an Antec 500W PSU, just in case in matters; I've always heard nothing but good things about Antec, so I assume it's not my PSU. Thanks for any help!
 
Try powering up with just your cpu,mobo, and power supply. If it doesnt power on, your power supply/mobo is dead. If only the fans come on, your cpu is dead.
Test the ram also.
 
I had a similar problem and replaced my motherboard, but a few weeks later my hdd died, and when i replaced it with a new one that one corrupted itself and maybe even died also. a motherboard, and 2 hard drives seem to be pointing to a bad and old psu. I would check psu first to be on the safe side. I have yet to check my old psu, I got tired of trouble shooting and decided it was time to move on.\

If I'm not mistaken mine is also an antec and it's wattage is well over whats being used.
 
Hey, I unhooked everything and tried to turn on the power but I still get nothing. It seems now that I probably just have a bad motherboard. Thanks for the suggestions though!
 
My computer starteed doing the exact same thing yesterday so I cut the green wire and a black wire on the atx power connector and wired them together to turn it on and it's still not doing anything. I think it is the motherboards that are doing this because I have tested all my voltages and they are all within acceptable range.
 
I forgot to say that the powersupply and all drives and fans power up but still nothing on the screen I even tried replacing the video card.

can you go back to the point when you were getting checksum error..? you should have tried flashing your BIOS...
