Right so I leave my PC in full working condition for a month and i come back to it not working.

Basically PC goes through BIOS fine but then the screen goes black after that never gets to Windows.
At first thought it might be the graphics card had been moved by something so re-seated. Same problem.

Just reset the CMOS and changed all the boot priorities problem still occurs.

......

Whilst im at it I think ive got a virus on my digital camera mem card. Can view all the pics fine on the camera but when you plug it in via USB it recognises the card but there's not DCIM folder for me to access. I know i can reformat the card and get rid of the virus but i want to keep all my pics.

hard drive spinning up?

if you press F8 on bootup can you start up in safemode? or does it still just go to black screen? (or whats the last thing it does before going to black screen?)

If you can't boot up in safemode either, its likely something has gone wrong in the hive files. To fix this you can boot up via a windows cd, login to the recovery console and go to your windows directory and cd to a hidden directory called repair (cd c:\windows\repair\) then copy these files to the C:\WINDOWS\system32\config directory (you might want to try copying everything EXCEPT the software ones first and try that, then if unavoidable copy the software ones if it still doesn't work).

These are backup hive files when the OS was installed. Essentially that should allow the computer to start up, however it will unregister drivers (video/sound etc.,) - they're still on the system, so when the computer starts you should be able to run through the device manager driver updates pretty quickly.

The software hive contains registry keys added by software, so if you have to restore this you'll probably need to reinstall your applications which is a ballache, however if the computer is stalling on startup, it's more likely a system (driver) or security hive issue.

Assuming the memory card is either virused or corrupt but is still mountable as a drive, have a look at software called file scavenger (it's old and clunky, but I've used it for years as it's proved very functional)... technically paid for software but am aware it's available on the torrents. If it is a virus I'd recommend trying to recover the files first then run an AV scan on both the dodgy camera disk and the recovered files (as AV tends to be a bit trigger happy deleting stuff )

would assume if it wasn't the system would try all available boot devices then splurge the generic 'boot disk error, insert system disk and press enter' type message. If the screen is blacking out I'd assumed the computer was starting up windows but then hanging, but lawpf can correct me there if I've gotten the wrong end of the stick.

goes through all the normal american megatrends bios stuff then never gets to windows.

not at home atm but will try those fixes over the weekend. thanks for the ideas.

well tried lots of fixes to no success.

So i decided id just buy some new parts. So i got this: http://www.overclockers.co.uk/showproduct....339&subcat=
