You're quite invested in this rig. Most of us PC guys on this board have a setup like yours and we all have our own business were we go onsite and solve problems like these.

Your troubleshooting can be done with us but we have this impediment of having to exchange mail to ask and have you answer questions.

Can you bear with this process to get you back to go? It may take an hour or so, it may carry on until tomorrow. I'm on PST and usually up late. Tell me what time zone you're in and just how frustrated your are right now so we both can judge whether to pursue fixing you now or start the process now and finish you up, if need be, tomorrow.

Do you have a VGA (blue) connector and a DVI or dual DVIs on your PCIe display adapter? And have you been in your system setup bios to check the onboard vga disabled and offboard enabled?

Hp 9515y monitor says no input while computer is still running; verified 350w PSU 12v output; tried new galaxy gt 430; still no signal

Basically your monitor is not receiving a signal from the Computer. In other words your computer is not passing the Power On Self Test or POST.
See my published guide for more detail, it is entitled My Computer is not turning on!!! Is it dead!!! No POST!!!
Remove the GPU and try onboard VGA. Increase the volume on your speakers, then power on your system. do you hear the Windows sound? If not then Windows is not loading.
See How to Remove the Side Panels of My Computer Chassis!!!
and How do I reset my BIOS/CMOS to defaults?

I would say that your computer mainboard has died, It is possible that the BIOS Chip has failed as it is the first operation. Basic Input Output System.
You could try and get a new one, it is worth a try. will be able to get you a new chip for your mainboard.

Take care!

May monitor shuts down and cant get it open even though the cpu is still running. i have to pull the plug and put it back on just to get it started again.

Do you a nvidia video card? If so, go to the Nvidia site and download the latest driver. My HP Desktop was doing the same thing and since I did this I haven't had it to happen again.

HP dv8000 w/vista keeps restarting and the monitor is blackl

Try to boot into vista's safe mode, this can usually be done by pressing F8 after POST, but before you see the vista loading screen.

Once in safe mode go to:

Start > Control Panel > System

on the left you will see " Advanced System Settings " Click that

a new window will pop up with your system properties, click the " settings " button near " startup and recovery "

Make sure the little check-mark near " restart automaticly " is NOT check, then apply, and OK out of all screeens and reboot the system. If the problem persist, you may need to insert the Vista disk into your system, and do a recovery, or restore.

Screen not starting after installing graphics card

Hi rohit1987,

The XFX NVIDIA GeForce 8600 GT 256MB DDR3 PCI Express card uses two DVI ports on the back of the card. Display is most likely coming from the second port. Try moving your monitor cable to the next DVI port. You can do this while your system is running.
If you still do not receive display, post that here & we'll go over some other possibilities.

Good luck rohit1987!
Thank you for using fixya.
