My Desktop computer is dead

WELL step one is setting the PC, to a correct resolution the monitor allows. (I use avideo signal generator) so I not need to play PC games to do that. but can, forcing PC to 1024x768 is best NOW.
good news the screen is not dead. 2006 monitors most are CCFL dead. now. no text error and no OSD screens, do you get OSD button to work?\/
learn these rules. first (off CCLF lamps are not dead)
the monitor power button blue means ON, off black means powersaver mode (dumbb idea this color black, yellow best)
this old old monitor fails on vast kinds or modern resolutions
OSD page one try RESET?
learn that VGA + DVI scans can fail, on vast monitors. we simply go to the OSD menu and enable DVI, forced,source select Digital.
and now it all works well that is if no using the correct DVI port on the PC, mine has 2, one on video card and 1 on the mobo
the mobo port IS DEAD when VIDEO cards are present.
so that is one more way to get it wrong.
there is no w10/11 support on 2006 monitor that means w10 must be forced to a legit resolution manual per below. in desktop settings;
most monitors the OSD button is dead, after 10second just turned on. so power off, power on and hit OSD menu,button.
best is use PC with a modern monitor an force resolution to one of the below then plug in this lame 2006 monitor and see it work.

only these work at PC end to MON. note no 1080P !!!!! ouch!
VESA, 640 x 480
VESA, 800 x 600
VESA, 1024 x 768
VESA, 1152 x 864
VESA, 1280 x 960
VESA, 1280 x 1024

next time buy monitors 2010 or newer never older. oK?

Apply new turmal compound to your cpu and try to start again

It seems like your PSU has malfunctioned.
Try to check your PSU, see an attached article to guide you. How to power up an ATX Power Supply without PC

If it's a laptop, you can plug in a monitor to see if you can get a signal there. That might tell whether the problem is the graphics card or the screen. There's a Fn/Fkey combination that turns signal on to both monitors; you may need to press that combination to use the monitor.

that means just what it tells you
the PC is dead, PC video dead or video cable unplugged , dog chewed it , pins bent or plugged in wrong on 1 or both ends.
or monitor not selected to the correct input port (OSD)

PC power lamp glowing not amber or blinkikng
PC fans spin , PSU fan and CPU both
if PC has GPU card in PCI-express slot it must be use those ports only for video.
PC not beeping
PC not texting errors post.
PC not blinking codes on LED or caps lock or POST ERRORS !
NO PC told
PC dead.
PC not stuck in sleep mode , hold PC power button for 10 full seconds to end it, (cold boot that is)

test monitor on end good PC? yet?

1) Reset your computer.
2) Unplug the cable from the computer to the monitor and check to see if its damaged, if OK plug it back in.
3) On windows computer, click windows key / windows system / control panel / device manager / display adapters (click on icon) / Update driver

a Desktop so old it still has floppy drive, (we trash these the PC)
PS2 keyboard and mouse.wow.
