I have a problem with my Dell Optiplex GX520 PC. Everytime i turned on the PC, its always show nothing, and the power light are Orange (which means still booting), i waited for 1 hour, it turned green (Ready), but it shows nothing.
So i check the RAM (With opening PC Case), its 1GB. So i Updated the RAM to 2GB, but still doesn't work. I try 5 times, its turned on and booted, and successfully loaded Windows.
But, after i update the RAM, the next day i turned it on, its shows nothing again when the power lights are Green (Ready). I do these step:
- Cleaning the PC from dust (Processor, RAM, Motherboard, DVD), still make no effects
- Change their slot, success, but the next day its Blank again
- Checking for Virus and error Registry (Using SMADAV, and its trusted app, so its not a Rogue Software)
- Using new RAM, still make no effects
So, whats wrong with my Computer? are Optiplex GX520 are old PC's, or there's something like Outdated BIOS or OS (I using Windows XP SP3)?
