Trying to fix a computer for a friend. He changed some settings in bios and now when pc is turned on, it doesn't go through boot sequence. It only shows a few random letters and numbers (maybe a music note?) at top of screen and rest is black. He initally had the problem of "Insufficent resources to complete API" or something of the sort. I believe this was due to full hard drive. I've tried to ctrl alt del, and pressing del to get back into bios with no luck. Nothing will load (HD, CD, 3.5 etc). Any help or info would be most appreciated.
Thanks in advance.
