Hi all

New PC buld and having problems

Its all built but when i tuen it on nothing happens, no beeps and nothing at all on the monitor

[I assume attaching an anlogue monitor to a DVI only graphics card (with an adaptor) isn't the problem and should still work]


The mobo lights are on
The CPU fan is working
the other case fans are working

Also, there has been no smoke/sparks/explosions

Any suggestions as to what could cause this?

many thanks

Does your motherboard not have some form of display, for giving error codes?

As for beeps, my latest motherboard came supplied with a small speaker that connects to the front panel pins, rather than one on-board.

Check your graphics card is seated correctly and that the power connector is connected.

Also check that your ram is seated correctly, and the clips either side are firmly holding it.

As a last point of checking, make sure the CPU is installed correctly.

Post up your spec, including your PSU.
 
thanks MikeHiow

spec is:

Asus P5q deluxe
OCZ 4gb (2x2) PC28500c5 1066mhz
Antec Tri 650w PSUIntel Q6600 2.4 (gteed to 3.3)
Antec P182
Nvidia 7900GT

will check as suggested and report back

Is the ATX 4 Pin connected to the motherboard from the PSU?

Can also be 8 pin.

hmmm - no

i have a 24 pin power connector - did you mean the one thats makes it up from 20 to 24 or a separate one?

i have both a spare 4 and 8 pin connection thats not plugged in - should one of them be plugged in

gonna check my mobo manual

Well it could be POSTing now and then encountering an error but it has no speaker to output the error message. Just something to look into fella :)

Check your manual and look at Page 2-34.

(Based on my P5Q Pro manual)

Both should be in at all times.
 
yep - just found it as well

looks like i just been stupid :(

will tray again - need to disconnect this pc before i can try so won't be able tp post for a while

well - it was me that messed up by not connecting the 8 pin power plug to the mobo Doh!

BUT

am having problems installing windows vists

this is what happened:

1) enabled AHCI in BIOS (have to do this to get Linux install apparently)
2) went through vista install and chose to partition the drive (for dual boot later)
3) then installed vista - it rebooted during the process but when it got to the final bit - completing installation of something it went on for 2 hours (its only a 350 gig partition) but eventually the screen went blank so i rebooted
4) It starts to boot from the hard drive but gets stuck - if i reboot i get the safe mode menu and the error message talks about a possible hardware problem

so - i boot from an Ubuntu Live CD which starts fine - when i look at the partition editor it says i have 3 partitions - shouldn't there only be 2?
i seem to hvae:
1) an unallocated 1 meg (yes meg) partition first
2) 350 gig NTFS partition
3) 585 gig unallocated partition

is the 1 meg partition supposed to be there - if not could thiks be whats causing the probs?

thanks

Check your voltages (Particularly ram) , and that your heatsink is seated correctly.

I had a similar issue with mine taking ages to install, and being unstable once booted. Turns out the CPU cooler had become dislodged, with the top two pins not clicked in correctly, and only cooling two of the four cores.

I can't image that un-partitioned space would cause a problem.
 
thanks MikeHiow

i have the same ram as you - what should the stock voltage be? - i haven't OC'd it yet

also, re the cores - were 2 not working at all? (i'm running my linux live CD at the moment and all 4 are working, though i can't tell the temps and the cores aren't under strain) and how did you tell that was the prob, can you get a prog that monitors the temp of each of the cores separately, or was it jjust a manual check?

thanks for all the help

OCZ recommend 2.2v

I Just have two sticks, and I run them at 2.0v.

Hrm, there are packages that will monitor temps under linux, or you may even find something if you hunt around /proc, your bios should have some kind of temperature monitoring, too.

Mine was more of a lucky guess than anything, I managed to keep the machine stable long enough to install Speedfan (under vista), and sure enough, two cores at 99c, two at 30c idle :)

It wasn't immediately obvious that there was a problem with mine when looking at is visually, however, when I pressed on it (The top two pins wern't fastened, so it "drooped" with it's weight), 1. it moved and 2. the temps went down :)

It's a shot in the dark, but worth a try. Try pressing on your cpu cooler, ensuring it's flat, if it boots when you do this, you have your culprit :)
 
no luck with any of the above stuff

i tried loading some AHCI drivers - no luck

i did notice the following flash up in BIOS - not sure if its the reason - and it can't be correct (can it) as my vista install disk seems to recognise it and let me partition it

Marvell 88s61xx adapter
bios version 1.1.0.L70d
Adapter 1
Disk Information - No hard disk found

or is this refering to an IDE drive (that i don't have) rather than my SATA drive?


thanks
