Dell Monitor not receiving signal

[Njdevilsfan357]

I was on world of warcraft playing the game fine, all the sudden my screen had a flash of red and It seemed the computer froze. I restarted the computer via the power button. Computer was running fine, So i reopen world of warcraft as soon as i got to the loading screen my monitor had the flash of red again. I restarted to computer, this time I tried to turn the computer back on the monitor wasn't recieving any any signal. I tried several more times and same thing. I tried wiggling, taking the cord in and out and still nothing.

Also to add Every time it boots its goes into sleep mode after telling me it isn't getting a signal from my computer, So I doubt it is my cable.

I have also now tried different monitors and cables. This computer is about 3 years old, Its a Dell xps 420 and has been working fine intil now.

I cannot get my computer to do anything, and I am at a lost what to do. I keep getting no signal from my computer. It seems as if it Is booting up, its turns on and the green light comes one and just stays their.

No idea

I would contact Dell here: https://www.techspot.com/vb/topic100658.html
And ask them if this is a known fault or something (ie it could be faulty ram etc)
