I have an AcerPower 650 mHz with 128 mb RAM, integrated video and ethernet that will not boot. Once power is turned on the screen just shows a mish mash of colors, there are no beeps and the hard drive light is continuously on. Somebody had been messing around with the machine and had slaved another hard drive to the one in the machine and in the process crashed the machines hard drive. He then messed around with the hard drive eventually taking it out and trying to fix it by slaving it to another computer. The hard drive eventually ended up on my hands and I had to use the recovery disk to return the hard drive to its original factory condition. I did this on a machine identical to the one the hard drive came out of and the drive worked fine. Now I put the drive back into the original machine and the problem described above occurs. Am I right in assuming that it is probably not the hard drive but possibly the bios or mother board got messed up too?
