one year back i purchased a dell pc. it came with a nvidia 8300 graphics card which i hooked to my dvi compliant monitor for use as a primary display device.
several months ago whenever i turn on my pc it would turn off and on for exactly 3 times before it boots windows. and the monitor would display a no signal warning despite proper factory setting at auto detect and attempts to switch it to digital and analog mode. however as soon as i plug the old vga cable to the mobo vga plug my monitor would work and all seemed fine.
back then atleast having to resort to use my pc with onboard mobo vga i was able to see a windows message popping up the instant i plug the monitor’s dvi cable into the dvi port on my nvidia graphics card, nowadays i just don’t see that anymore.
device manager display only one primary display device “standard vga” and that’s it. back then i recalled seeing the fine print of “gf8300gs” displayed there.
display drivers used were from the disc and bios is factory default, no OC nor flashing has ever been done, as i’m no geek, i never dare to touch even the device manager or the brightness setting on my monitor. my pc has always been protected with norton and avira, as well as adaware and iorbit of which is always updated and i’m proud to say i’ve not even ventured anywhere on the net that gave even a spyware and virus reading, especially when i surf with firefox
i tried taking the graphics card out to reseat it, but every tug and wank gave an awful fright. it won’t budge, it is secured as the wires connected to it.
restarting the pc lots however yields the same result of no signal for the monitor, where as only days before the dvi would be working fine again.
i recalled in the early weeks of my usage of then this brand new pc and the entire screen simply disappears for 2 secs before coming back on and reporting that the nvidia display driver has recovered from a “serious critical error” i didn’t have internet back then nor do i run it for anything other than my old purchased copy of coral draw and msoffice so virus was out of the question.
so my question would be if there are any obvious symptoms/signs to which to tell a video card is failing or has failed. any help is greatly appriciated, thank you mates!
