[HELP PLZ] Computer not starting unless i cmos reset every time (?)

[Everztar]

Change the PSU - Not enough juice. Most probably a faulty one.

how could 750w not be enough juice for his crappy machine? :/

Doesn't always work that way. But if I was a betting man which I'm not - a faulty PSU. Happened to mine.

so your psu managed to run 20 mins and then didn't manage it anymore? =p

Probably issue with heatsink or faulty fan.Some BIOS shutdown the computer when the fan runs unproperly to protect the processors or it could be with the shitty Windows..mine gives BSOD whenever I open windows media player..probably issue with graphic card driver..It is unlikely any problem with the RAM if it fits it should work.You wont be able to boot with the faulty RAM..and in b/w just 5-10 mins are enough to heatup and shutdown

but all fans are spinning? :c

Did you check the power cable to the cpu fan ? if there's similar power cable in psu , try connecting it , if that works that means cable is damaged .
maybe it could be psu , try another psu instead of current psu .

You should equip an inter cooler, or water cooler whatever, either the voltage supply the psu Is probably faulty, or ur system is being heated up to the point it shuts down to automatically to prevent damage to the components. The CPU can heat up in a little time as even five to ten minutes, also depending on what programs you're running also increase the load and stress allows more heat which the proeccesor generates. Same for the GPU, you should check the activity. To check the temp rates.

If it's over or around 110 Celsius then I'd worry a little.

If there's a problem with the power supply, then it's defective. A 750w corsair psu that is properly working is more than enough to power that machine. My guess is that your friend has a faulty motherboard, but he should check for overheating before replacing it.

The problem is the motherboard. Motherboards can some times get this problem. Tho rare it can happen. The friend must try to update the bios through the Asus website if they can. If they cannot it will require replacement. The bios is corrupted. He can get the bios by searching the motherboard in google and finding it's driver support page, then on that page finding the latest bios and then installing it.

thanks Yard, we've ordered a RMA ticket to send it back tomorrow. we wouldn't want to flash/update bios in order to prevent "Warranty Loss" as Asus often won't help you replace your motherboard if you've updated bios :/.
could a new motherboard work?

If Asus is like other companies, the RMA process should be rather quick. Big companies don't really like their name being tarnished especially when the hardware they've showcased isn't working to the expected functionality. Some companies may even present a gift card in these cases as an inconvenience apology or a more advanced motherboard for no cost. Just have to stress your issues while being polite. Try to see how the replacement process will go, if they replace the motherboard with the same model and it's corrupted as well they may offer something better. When the motherboard is sent to them, it'll be tested for functionality, if the problem can be seen by them, they'll replace it depending on how far along your warranty you are and your purchase history with them. Some companies don't even check and just send one out anyways. However, most likely they'll send a new one out to the friend's home and it'll be in working condition.

Based on the reviews here, I'd recomend him seeing if he could either get a refund and buy a new motherboard or getting a better model from them.

Corsair PowerSupply (PSU) CX 750M 750Wseems pretty compatible for the mobo.ASUS P8Z77-V LX - ATX / Z77 .though it'll b really good if u pick up a multimeter & check out the jacks power out voltage.....it usually 'll be specified in the PSU ....label.... specifying correspondin' voltage ranges 4 the wire colors......& check if there's any steep increase in C.P.U. /G.P.U. fan speed .....& temperature....& if so it sure's a faulty socket voltage supply......or P.C.I. express slot fault....in case of video adapter....if that's the case u should replace the PSU or the mobo should b tested for socket supply faults...if its not the PSU...itselftry flashin' the B.I.O.S. & check if video bios fault occured in the event viewer ...in Win 8.1windows is less dependent on the bios itself.....which r mostly handled by the drivers...written for the os...so u may have to try out other linux distros to check if its the problem of bios....which in case ur disto will fail to initiate kernel mode power up for the xserver / display out...in case of mint x86 or if the os uses emulated bios ....it may go unnoticed/....but it's worth a shot....try booting with just a single RAM slot operational.....& check if somethin' goes wrong with the system....& try swapping with the other one....& if that's the case u know what 2 do...if virtualization is enabled in CMOS setup try resetting 2 default values....or just clear the CMOS memory....by swagging out the cell & let the capacitors discharge whilst pressing the power button....for a couple of minutes...or so...& replace the jumper of CMOS to the next avail.try running the system without harddisk ...by external booting from a live media....& use a operation benchmark tool for checkin' out......If u really wanna solve the problem / figure out what wrong I would like to help out....b'coz I'm a harware debugger & helps my friend in building gamin' rigs & overclocking issues...but if u don't wanna do so....u can have an engineer check it....mate...it pretty much seems like a faulty B.I.O.S. / P.S.U.'s fluctuated socket voltage potential ....if not so....u sure much get the mobo checked ...assuming that ur C.P.U & G.P.U. r brand new....
