PC startup beeps twice, no signal to screen??

[AstroZombie91]

I literally can't even get it to boot in any way, I built it myself around 2 years ago, and it was fine, I then lent it to my mother.... who thought it was a brilliant idea to put a huge wad of paper in front of the main side fans which I assume overheated it quite a few times, since then it's been a losing battle trying to fix it.

I can't really remember what all the components are either which is annoying.

Anyway it now beeps twice, both short beeps, about 2 seconds apart, sounds like it's all firing up fine too, all fans spin etc.. have removed both sticks of ram and it did a continuous beep, which I have read means the cpu and motherboard are fine? hopefully... Put ram back in and the same 2 beeps happen, and no display on the monitor...

I think it's a quad core AMD cpu, with two 4gb sticks of corsair ram, and I've recently removed the graphics card because with that in it doesn't even beep or do anything at all, so thought it may have been that. (but it did start up and make all the usual sounds, just no beep or display)
also a 750w psu but it came with my case,so am thinking it may have been a cheap one...


Would it be worth me buying new ram and psu and seeing if that solves the problem? or are there any tests that I might not have done to rule those out?

Any help appreciated.

Thanks

not sure if that'll help much but those are from my orders on amazon so definitely the right parts! lol

if you can remember what the motherboard is, looking in the manual will tell you what the beep error code means, the fact it changes when you remove ram means that whatever the 2 beep code means, will definitely tell you the answer.

Have you checked the CMOS jumper? Have you tried clearing the CMOS? It could be your graphics card is fried, or your HDD.

I managed to get to the login screen and actually log in, it loaded and then it froze and I had to crash it. When I restarted it didnt appear to all be powering up properly. Reckon it could be the PSU? Graphics card I will be replacing soon too but it's quite new so hoping it wouldn't be that.

it actually kinda sounds like your CPU fan isnt working and the CPU overheats by the time it reaches the login screen. although yes it could be the PSU, go to the store and pickup a new one to see if it solves all the problems, return it if it doesnt or you get the old one working again ect.

ASUS support site gives you bios beep code information since that doesnt match, the manual suggests that there are also led's on the board that will inform you of what issue there is on bootup.

Firstly, before buying a new PSU take out your RAM, reseat it and try again.
If not try different RAM slots. Do you have a mobo with onboard graphics? (is there a blue vga port on your motherboard?) If so, take out your graphics card and plug your monitor into the motherboard instead.

Post your results!

Right, taken graphics card out, started up with vga in the motherboard slot, and it booted up, i restored bios to default settings too,but at first the bios was being very odd! yellow and orange stripes and frozen screen, and also a blue screen in the bios?!

But now managed to get into windows and log in, no crashes or freezes as of yet, psu is making the right powerful start up sound, so maybe it is just the graphics card, YAY!

I think it's fixed. But I won't know for sure if until I turn it off later and try turning it on again, or if it crashes again... and wont turn on.

But for now I am happy that I can back up my files to reinstall windows which is what I wanted to do in the first place.. lol

Thank you all for your help!

No problem!

Try your GPU in someone elses rig and see if it boots.

 

[AstroZombie91]

Nope okay, it's happened again, it froze once I possibly had too many things going, then I crashed it and attempted to restart... and now nothing. lights all coming on but the PSU doesn't sound like it usually does when it starts up and no beeps at alll... -.-

 

[Mr Dobing]

Ok, it's definitely sounding like a faulty PSU now. It might've booted before because you took the GPU out of the equation and now it's reached its limit.

Got a spare PSU or one you could borrow just to clarify?

Do your fans fire up at all?

 

[AstroZombie91]

Fans spin and lights go on, but no real powerful sound, like they arent getting enough power... and no don't have any spare. Is there any safe way to test the psu out of the case? If I unplugged it all??

 

[Mr Dobing]

You can test it with a multimeter. See - http://pcsupport.about.com/od/toolsofthetrade/ht/power-supply-test-multimeter.htm
