Hello everyone. The thing is my pc was not used for a month. It worked last time though. Today i power it on and it doesnt boot. im using asus p7p55d pro that has debug leds for cpu, mem, vga, boot device. So i open the side panel and see debug led of cpu is up. *not a good sign*

Here are what i done so far. Unplug and plug 24pin, 8 pin connector, reseat the cpu (i5 760), graphic, check for bent pin (found none). The red debug led is still there.

Im worried something might went wrong with mainboard but not the cpu so i put my cpu in a different system which is running fine. Power pc on and i hear 7 short beep. I google its meaning. It said "virtual mode exception". I think my cpu is dead or something.

I want to put other cpu in my system but im afraid that it might fry the cpu too so i havent tried yet.

Extra info: Im using Water cooling. 2 or 3 years ago there was a crack in a fitting so water leaks quite a lot on the mainboard. It wasnt power on though. Since then my system is acting strange. It couldnt memorize date n time though i already replace with a new battery, sometimes it wont turn on, it run kind of slow even after a clean install of OS (slower than my old core 2 pc). But it still works so i dont pay much attention to it. And now its broken.

Any advice on this everyone? Are mainboard and cpu both dead? And do i need to buy a new rig?
All advices are welcomed and appreciated

this time arround have you tried to reset bios ? Evt. try and take out your bios battery for a few mins and put it back in, just to make sure that it isent just a biosinteruption thats causeing it.

Sorry for the lack of info.
Yes. i did it too. It dont work either. In fact i dont put battery on the mobo cause it wont "remember" anything, date time, other setting in bios. Even i replace with new battery, it took me 5 or 6 battery. The jumper to reset cmos is in its normal state.

I suggest taking all the parts down. including motherboard, check visually for any unusual sign or smell. Then you can try powering up (assemble them outside case) in that way easier to find. what you can do its install cpu and memory + power supply only. then you can power it up and see what debug code will say. If debug code says no monitor or no keyboard installed, then youre good to go.

I'd try a different power supply first. If that doesn't do it, then I'd guess motherboard.

^^This. My first suspicion was power supply. Beg or borrow one to hook up temporarily to see if the system boots. If it doesn't, then I agree it is likely your motherboard, with nothing powering up.
