As I still haven't got to the bottom of it I thought I'd ask you lot

The main pc I use died on me about 10 days ago. On a reboot just stayed a blank screen. Tried disconnecting 1 thing at a time but still nothing, ended up down to main hard drive and dvd r/w drive and still blank screen, not even as far as memory check. So reset cmos and it came up, went into bios and reset the date etc. saved and exited and back to blank screen. Reset cmos, pressed F1 to ignore smos settings, halfway booted into vista and BSOD! Reset cmos again and booted to vista dvd, into repar console and did chkdsk c: /r let it run but still doing the same thing...

Fitted new stick of ram, no difference. New motherboard, no difference. New hard drive, no difference. Only thing left is processor and I can't see that causing it! Any opinions?

does it have on board graphics card?
if it is a separate card that could be the problem or even the PSU

1 does it have on board graphics card?  
2 if it is a separate card that could be the problem or even the PSU

yep..an on board graphics card and a seperate one together can cause the problem..try connecting the monitor to both vga outlets to see if any have signal..and if still nothing take the vga card out..

secondly you say you tried a new motherboard and still no difference that means also it can be PSU..

Try changing/testing the little button sized battery on the motherboard - if it's dead replace it.  


Sorry - forget it if you've changed motherboard

[Welung666]

Original board was a Foxconn Winfast 6150K8MA with onboard graphics but never used them, have a 512 NVidea card in PCI+E. New board is a LanParty gaming board no onboard graphics, using my original nvidea card. RAM is a single 1gb DDR also tried 2 x 512 sticks no difference. Processor is an Athalon 64 3600+ PSU was new 3 months ago but haven't tried replacing that yet

Brand new board

PSU is still at the top of the bathtub curve for failure over time then

I'll have to have a dig and see if I have another PSU to try. Problem is it needs to be high powered PSU as I run quite a few hard drives.

try a simple configuration.. 1 hard drive 1 memory stick no dvd

and check the extra cables and mobo chasis mountings..

[cem_devecioglu]

and dont connect the reset switch!

and you said you connected  some number of hard disks..

may be this caused the failure of psu..

If you are now using a LAN Party gaming board they usually have switches built onto the board for easy running outside of the case if you ever want to test it.

Must admit I would be leaning towards PSU on this. If it gets half way to Windows the graphics card is working. Disconnect all drives except the HDD with Vista on it and try again. Have you connected all the extra plugs from the PSU to the motherboard? My LAN Party board had a 4way Molex and a 3 way Molex connected to the board apart from all the usual ones. Think this was because they hadn't used the standard SLI power connectors at the time but not certain.

Getting half way into Vista could also be a driver problem, you say you changed the board but if it hasn't worked since all the drivers will be wrong. Changing the board will also mean you need to reinstall/re-activate Vista as well.

Dont you mean changing the hard-drive will mean re-installing Vista (if there's no o/s already on there)

[nabsim]

No. If you have gone to a different motherboard you will need to reload/re-activate Vista. Usually it will start up but say you have 3 days to activate. If you replace the motherboard with an identical model you will be okay.

The BIOS and a few other parts are used to produce a hash key that is then used to make sure you are not cheating with licenses. If worst comes to worst you can choose to activate over the telephone and get it sorted.

All this is presuming you are using an OEM copy of course.

I suggest you stop whatever it is you are doing and concentrate very hard on diagnosing the problem.
1. the PC died about 10 days ago
2. you reset BIOS and now get the BSoD
3. No matter what you do or have done since:
    a. you still get the BSoD
    b. symptoms are now different
4. if you have ended up with 3.a the reboot to Vista Safe Mode

5. if you have ended up with 3.b please explain exactly what you get once you power up.
