Multiple beeps can be either bad video card, bad memory, bad CPU. Wouls try any old video card first.
What beep code are you getting??? They can be a series of short beeps, short then long and similar combinations thereof.
Depending on the make of the BIOS you can go to their site to see the beep codes [possibily].
I have an older PC -- Custom built -- Intel Pentium 3, Win98, Maxtor Hard drive, CD-ROM, Floppy....when I turn my computer on, it's getting power, lights on, fans going, lights flash on keyboard, but then the hard drive just gives long beeps and does not boot up. I have disconnected all peripherals except mouse, keyboard and monitor. I just get beeps. Thanks for any suggestions!
