i opened up my system today to simply add a new sata hard drive and now it wont boot
i see the gigabyte logo screen on my monitor but then the screen kind of displays some multicolored vertical pattern on the screen, then it goes black, and then it redisplays the gigabyte logo screen. it does this over and over again until i turn off the power.
i'm unable to enter the bios or anything else. the keyboard seems completely unresponsive during the boot process.
i've gone as far as disconnecting all drives thinking i'd at least get a 'no boot device' error but that doesn't happen either. just the logo screen, a flash, then black, and then the logo screen again. over and over.
note i don't ever, and never have, heard any bios beep codes during the post process. i don't think this mob has a speaker and i don't know how to connect one. Note i've connected ear phones to the line out connector on the mob and they're silient.
other than the screen showing the gigabyte logo over and over, i do see the fans start and when the drives were connected i could tell they were spinning.
i don't know what i've done but any help figuring it out or better yet fixing it would be very much appreciated.
