Hi have a Dell Optiplex GX520 and i am having a problem where after i have seen the Dell logo the screen goes blank (black) carnt see anything on the display. If i pull the monitor cable out of the back of the tower and then put it back in i can see whats on screen for round about 2 seconds (not long enough to click anything). I should state that i have had this problem before with another computer that was taken to a tech guy and he said the motherboard had gone. But i carnt see the same thing happening again with this one. The only things i have kept the same from the previouse desktop that had this problem is the Hard Drive and The Monitor (the monitor works fine as an external monitor for my laptop so dont think is that). Can anyone shed some light on this for me please as to what i should be done..?Thanks in Advance
I've seen a lot of issues with Dell machines doing that sort of thing. I find, that running a diagnostic cycle usually sheds some light. While the computer is booting, tap F12 to get to the one-time boot menu. From there, let the diagnostic run and post back any error messages that you get.
I have run the hard drive diagnostic and doesn't report any issues been there with the hard drive. I don't see any other options to run any other type of diagnostics. And another thing i should probably of mentioned is i can not boot from disc either because the BIOS doesn't recognize the CD/DVD drive for some reason. And the HDD is completely empty cos it was reformatted ready to have a new installation of windows vista home basic on it, Then i run into this problem with it. (The hard drive was reformatted in the previous computer that had this problem)Just to add the previous computer that had the problem was an Acer M1100
I have re-run the diagnostics you previously stated and this was what was displayed.Floppy diskette seek failureHard Drive Diagnostics running, please wait...Drive 0: Hitachi HDS721616PLA380 - PassDrive 1: No DeviceDrive 2: TSSTcorpCD-RW TS-H292C - Diagnostics not supportedDrive 3: No DeviceTest Complete, Press to rebootHope you can help with this.
It could be a mother board failure.
