This computer was up and running.  It servers as a file server.  2 users were complaining that they could not access the shared folder.  I logged on to the pc, right clicked on my computer, selected manage.  When I selected shared folders and then clicked on shares, i received a message that I could not access it because the service server was not running.

I started the service and all was fine.  I then rebooted the pc so that i could make sure the service would start on it's own, and now we get a blank screen after the posts run.  

I started the dell hdw diagnostics.  It gets through the first stage.  Then it will ask if i want to continue with the tests, if I slect yes or no it freezes.   If I try to boot to the utility partition, the screen goes blank again.

I was able to boot to the windows cd, and run chkdsk /r.  It finished but it still will not boot.

The PC has 2 memory cards, i tried removing each one and booting but received the same results.

I can slect f8 and select boot to safemode, but again i only get a blank screen.

I don't think windows is loading at all.  While in the blank screen, if I take Ctrl Alt Delete, the PC will reboot immediately.  

Any help is appreciated.

Your issue to either a driver, application or hardware. You have eliminated memory but not video memory. Event viewer will give a good idea what is hanging. In the meantime I would eliminate software by going to start , run then typing msconfig. uncheck everything that automatically starts up see if it boots. If it does the the culprit is software. I advise you that the only program that needs to start at boot is Anti Virus and Anti Spyware. If this fails then I would change your video card. Servers really dont need much of one sone a scavanged known good one should work fine.  Hope this helps

Well if it is out of commission you could always hook the harddrive to another PC and run Malwarebyes against it to look for virus/rootkits.

Okay, it was a virus.  I removed the hard drive and scanned it with my laptop using malwarebytes. The scan resulted in 12 infected items. 9 of which were rootkits.  After the scan i put the hard drive back into the desktop and booted to the OS Cd. I then used recovery console to run fixmbr.  After that windows loaded.  I then scanned it again with Mcafee, which was already loaded on the desktop.  It found some more infected files.  I am going to use combofix.

As BCipollone suggested, I removed the hard drive and scanned it with another system.  I used a data transfer kit to connect it to my laptop.  I then used fixboot and fixmbr to fix the boot problem.
