blank screen after system crash (brand new parts)

Teh Jesus · 01-05-2008, 07:02 PM

i decided to upgrade my computer and all was going well all components and windows installed fine and it worked fine for about 14 hours then while i was updating wow (world of warcraft) then about 88% in the comp froze (not 100% sure when it froze as i left it to update while i did something productive like watch telly) as a last resort i had to do a hard restart, basikly just turning off the computer and back on again skipping the propper shutdown rutine. as it restarted my monitor was black and the power light was flashing as it does when it is left on without the computer being on.

the monitor is a samsung synk master 913n and the graphics card is a club 3d nvidia 7850gt. i thought it may be the monitor so i took it to a friends and hocked it up to there rig and it worked fine,

i then thought it may be the vga to dvi adaptor so i tryed a new one but to no avail.

so my mind then turned to the graphics card i had my old his ati x850 xt PE around so i popped that in and hocked up the monitor and still noting.

as far as i can make out the computer is POST'ing and booting into windows (vista 32 bit home premium) but i cant tell as i cant see but im not getting any POST errors.

if anyone has any ideas on what it could be i would love to hear it cause im all out of ideas :(:(

Welcome to TSF. What psu is in the system , make and model and wattage. Also does the pc have onboard video also?

Teh Jesus · 01-06-2008, 02:35 AM

the pc does not have onbord graphics the psu is a 600watt jeantech modular the product code seems to be 290020 it also has a part number which is jn120f-600-ap12v 2

hope this helps

try another power supply on it

Teh Jesus · 01-06-2008, 06:52 AM

that PSU is a new one i thought there might not be enough power comming from my old PSU to power it and thats why as it got put under a bit more load it crashed so i got a new psu and that still did not work.

also i just went to get a new graphics card to see if it was that and with a brand new graphics card in the system it still did not work so i think that narrows it down to being a MoBo problem i think, maybe a dodgy interface on my new motherboard, i cant see it being the CPU but i really am stumped now.

hope you have some more ideas cause now my well of thought has run dry :(:(

what are the line voltages given in the bios

**emosun** · 01-06-2008, 04:14 PM

So you say you can hear it posting and booting but it just wont show it? You could try a pci video card to see if your pci-e video card slot burnt out

Teh Jesus · 01-07-2008, 12:48 AM

dai

i cant see the line voltages as given in the bios because i have no display unless there is some other way i can see them?

Emosun

on closer inspection there is no happy beep (the internal speaker is set up right) but there is also no destress beeps so im just guessing really that it is loading into windows from the noises it makes. a bit geeky i know but you can tell by when and how long the HDD spins if it is atleast trying to boot windows.

also the only spare graphics card's i have are another pci-e card and an old agp card and i think my even older comps were onboard video but i will try and find one but i have to work now so any other guesses while im at work would be apriciated, also all the help so far is apriciated thanks people.

Teh,

Did you ever manage to resolve this issue? Was it the MoBo in the end or something else? I only ask because I have just had an almost identical problem with a newly built graphic workstation.

The only real difference is that prior to this problem (as in 24hrs prior!) the computer would boot ok but show nothing but the black screen until the Windows logon screen appeared.

I would be very interested in any outcome you had with this problem. If it remains unresolved, I would be happy to share any of my own further findings with you.
