Hello,

As the title states my computer won't boot.

The computer was working fine yesterday my brother was on it watching the football. Anyway I've gone to turn the pc on today and got no POST.

The computer turns on, no signal on the monitor keeps switching between hdmi /analogue. After about 10 seconds the computer will just turn off and reset itself.
The led on the cpu coolers goes yellow /orange before this if this helps.

This is all just about confusing since my brother claims he used the computer to go on the Internet and watch football and now the day after the pc won't POST.

Please can you help with this and tell me what could have happened for the computer to not Post, thankyou.
 
Few things might have happened: PSU (especially non-branded one) could've died, memory stick, graphic card, motherboard.. Sometimes PC won't post due to dust&moisture, so cleaning & reseatting slotted components helps (in case of old computers). SPec your rig, please and do some basic checkup including CMOS reset with close-eye-inspection like looking for burnt components, smells, spilled capacitors = it will help to solve problem with your cimputer ;-)

as others have said, try a cmos reset and see if that helps, will put it back to factory defaults.

does the pc make any beeps on boot up as this also indicates certain issues

Tried cmos still won't post checked cables and gpu seated still the same.
 
do you have a on board GPU you could try or a spare GPU you could put in?

does the PC make any beeping noises when booting up?

Click to expand...

On board GPU is available.

Do not have a gpu spare to test.

Computer won't boot to bios in order to enable on board GPU unless yit does it automatically when the gpu is disconnected.
 
give it a try, if you have a GPU in a PCI-E slot, take this out and connect the monitor to the on board GPU.

if you have successfully done a CMOS reset then by default the on board GPU will be enabled
 
As bad as this sounds could anybody spec me an replacement psu and motherboard that is reasonably cheap and will get the job done, don't want to spend too much with chriatmas coming.

Thanks.

Hmmm your motherboard have DualBIOS so I looked up motherboard LED lights colours on google.

Yellow LED mean something wrong with memory sticks.
Orange LED mean something wrong with motherboard VRMs or circuits.
 
Please ignore Harl0s post. The mobo is the wrong socket/chipset (it won't work :confused:) and the PSU is massive overkill for your needs :rolleyes:.

I'd spend £4 more than the Corsair ED209 suggested and get this

top quality, longer warranty and more efficient.

I'd do that before you buy a mobo as well, as your mobo may be OK.


EDIT: Have you stripped your PC down yet to mobo, CPU and 1 stick RAM?
 
This is a strange coincidence, mine did exactly the same thing yesterday. I wonder if some driver was released yesterday that got auto updated and is causing problems. The only way i can get mine to work is to take the battery/powerlead out leave it for 30 mins then restart and it gives me the options to boot/reboot or load bios, the only option that works is to boot right away, then the PC is fine untill i restart again, then i have to do the same again.

MY spec aint exactly the same as yours but its close, see if this works for you, might give you chance to backup to a laptop while you try other options. I'll let ya know if i figure out whats going on with mine, and maybe it will help with yours, just rerolling drivers atm.

edit: Ignore me, pilot error here. My fat hands had knocked my graphics card causing bad contact with the PCI-e slot, and messing with the battery(which is under the graphics card) was temporarily pushing the card back up strengthening the contact.

I'm using a Z77-D3H and can assure you it is working fine.
He really does need to strip the PC back to Mobo, CPU, 1 stick of RAM before he does anything else. Anything else is just guesswork.
