Oh dear, I'm going to throw my pc out the window in a few minutes... I got two new sticks of memory (I am positive they are the correct kind) from my brother to put in my old computer (which i keep around to store/manage all of my photography stuff). I shut down the computer, unplug everything, blow it out, and then take out the memory which is currently in there... there are 3 slots, two were full of small sticks... so I take the new big sticks... put them in slots 0 and 1... and move one of the smaller sticks to slot 2... plug everything back in, turn on the PC and nothing happens... except my monitor is flashing "no signal" I try to replace the original memory sticks and with one in slot 0 only it will get into bios... but not past the following stage of the game... Intel 845 AGP Set BIOS for 81RXP F4 Check System Health OK, V Core = 1.500 Main Processor: Intel Pentium (R) 4 1.60GHz (100x16.0) <CPUID:OF24 Patch ID:0007> Memory Testing: 262144K OK and thats it... nothing after that, keyboard is unresponsive, I can't escape, cant hit delete, cant exit into safe mode... nothing. If I add a memory stick, one of the new large ones... the computer doesn't even get that far, it just beeps. the computer is old... My dad built it in 2002... i know the MB is a gigabyte... I don't have manuals for it. I read a ton of forums... somewhere it said to take out the MB battery and then put it back to reset... this does nothing. Is this some crazy memory problem? Did I manage to kill my video card? Any help is appreciated as I am currently one very frustrated girl!
