Have a PC I built a year ago. No issues the past year. Today while decrypting a bluray I came back to my desk and saw the bsod. I rebooted and got nothing to the screen.

The keyboard doesn't light up either. No audible beeps, nothing to the screen. I removed all the memory from the box, still the same. I disconnected all drives, still the same. I removed the GPU, nothing.

Its odd the keyboard doesn't light up, I guess that means its not even getting to the bios.

The fans all come on, I can eject the bluray tray...I'm assuming my PSU is ok. Its a seasonic 1000watter. I didn't have any power surges, etc.

Anyone know what my next step is? My mobo is an Asus rampage iv, I really hope the mono is ok BC I don't have the cash to replace. Appreciate any guidance.

I also have cleared the CMOS using the button on the back of the mobo and removing the battery. No dice either.
 
I wish I did. Too be honest I just figured a simple reboot would resolve. I plugged the video card back in but no dice. Fans are all going, video card is lit up. Just nothing to the screen and no keyboard
 
Its USB. But all the components seem to get power. If you look at the mobo you would think its cool. That's why I wasn't thinking PSU.
 
Have you tried powering it on with no USB devices connected? Any strange smells when you first opened the PC, or if you take a close "sniff" on the power supply?
 
No strange smells that I could detect. I have tried booting with no USB and no dice. I've tried to boot with basically nothing but the video card plugged in but no dice. Thinking of going to best buy to get a cheap GPU just to test a different one in my rig. Good idea or bad idea? Thanks!
 
I can try a new psu first. Will newegg take back the new one if it doesn't fix the problem?

Also, what makes you guys think PSU even though all fans, lights, drives spring up?
 
OK. More madness.

Powered it back on today and I got the bios screen. I had to hit f1 for config (probably BC I popped the CMOS battery). I got into the uefi and set the clock. I noticed my two ssds were disabled so I enabled them. Hit f10 to save and it reboots. Nothing to the screen again. Wtf. I rebooted again and it powers up, then reboots, then same thing. This is weird. I don't think its my GPU now since I got something to display. Anyone have any pointers. Very odd it decided to post today and not yesterday!!
 
@No audible beeps
you should get beep codes even with no video card.. if mobo speaker is plugged in or built in.. im out of it so dunno if there built in these days

@I noticed my two ssds were disabled so I enabled them
I thought you disconnected everything?

not going to beable to trouble shoot anything by disconnecting everything then putting it all right back together

@I didn't have any power surges, etc
I don't think a human can detect this. you could have surges everyday if the hardware has no surge protector and its outlet shares the same line to the breaker of a large household applience

...go back to barebone setup, and plug it into a different power outlet. if you did not already, make sure the barebone components are properly seated. If you don't have another computer to test the PSU for proper boot. and no multimeter, only thing i know of is disconnect PSU from everything, and use one of your case Fans as a test light by jumping it to the proper ATX pins just to see if that rail on you PSU powers it up. IF you have poor DIY skill. easyest thing would probably be to just borrow someone else's PSU.. It can be a low wattage PSU just for barebone testing post/bootup

Yeah, I plugged everything back in today just to see. Last night I had everything disconnected. I think I will just order a cheap PSU to test this and thinks like it in the future. My wife and kids all use laptops and nexus tablets, so not many other desktops.

Hear you on the surge, but it was in a decent power strip..but anything is possible.

Could it be a mobo issue? I just keep getting hung up on the fact that everything fires up and it posts sometikes. Mobo was expensive so that's my greatest fear. CPU as well. Thanks for any and all suggestions!
 
Hi all. I was finally able to save bios changes. Now I get bsod even in repair mode. Screenshot attached. Do any of you gurus know why I have to power down all the way and let it sit? It boots if I do this. It sees the boot disk and attempts boot, so that's good. What can I rule out here?

for your future reference, you can easily net search a bsod.
just have to search the first # 0x0000009c

Machine check exceptions are frequently caused by one of the following conditions:

# You are running the processor or mainboard beyond its specifications. For example, you are overclocking the processor or bus. We recommend that you run your hardware at the manufacturer-rated speeds.
# Noisy power, overstressed power strips, outmatched power supplies and failing power supplies can destabilize your computer. Make sure that you have a stable, reliable power supply to your computer.
# Extreme thermal conditions caused by the failure of cooling devices such as fans may damage your computer. Make sure that your cooling devices are all working.
# You have damaged memory or memory that is not the correct type for your computer. If you recently changed the memory configuration, revert to the previous configuration to determine what is wrong. Make sure that you are using the correct memory for your computer.

Yes, did that already..hard to find anything substantial other than it may be hardware related. I'm getting a USB stick with memtest on it to boot and run that. I still don't understand why it boots if the power is unpluggednfor 5 to 10 mins. In the bios, all the temp sensors show under 30degrees centigrade, so I don't think the CPU is overheating... Frustrating... Lol
 
That quote i posted from microsoft coverd all the bases

@still don't understand why it boots if unplugged for 5~10min
the answer is Heat. due to any reasons in the quote or previously posted, including but not limited to internal electric component heat you wouldn't beable to see, due to stress abuse or simply defect. most likely suspects tho are PSU or CPU

(EDIT: clearify - usually not the cpu, but in your case you don't specify anything, leads me to believe you were previously overclocking, i don't think OCing would damage the mobo, but the CPU, and or if your HSF is properly installed)

Very minor overclocking and through the software. Its been with the same setting for 14 months. I have had memteat86 running for 2 hours and the CPU temp is about 43degrees. If this run goes fine can I assume that my memory and CPU are OK? Thanks for the help. I'm a Linux guy and more on the software side ;-)
 
explain much? or just trolling?

I don't see how your monitoring temp if your live booting from memtest. unless you have an external aftermarket temp monitor? if so.. those were always about as accurate as a weather forecast, improper installation even more so.. hell i wouldn't even trust the built in monitor on the chip half the time. Enlighten me if things have changed, i havn't used a modern board.

dunno about the specifics of the test but if i were to assume, its Not testing CPU otherwise it'd be called cputest86
 
Not sure how I'm trolling bub. When you run memtest it lists the temp of the CPU while its running. It changes in real time right on the screen. Certainly running memtest must exert some CPU..no?

Memtest86 finished after 3 hours and passed. So I guess the memory is good.
 
I'll third the thought about a bad PSU. Seasonic makes some of the absolute best power supplies you can buy, but even they will have a dud here and there. I'm surprised that nobody as asked to this point, but can you provide a full system breakdown of your system components? What hardware are you running that required a 1000 watt PSU? Also, are you running off a surge protector or UPS?

One good thing, at least, is that your motherboard should still be under warranty (most ASUS ROG motherboards have at minimum a 3 year warranty --5 year for a TUF series board).
