Hi! So I just bought a new 1 gb crucial ram for my HP Pavilion Media Center TV m7750n PC, and I can't seem to fit the RAM into the slot on the motherboard (I have to force it in, and then the pc wont boot, and gives off a beeping sound). The RAM that I brought was crucial product #CT12864AA53E (1GB 240-PIN DIMM 128Mx64 DDR2PC2-4200 UNBUFFERED) and I'm sure that it matches the 2*1 GB RAM that already came with my computer (I verified the memory specifications with HP's website and other websites) Thanks for any suggestions. I am desprate for that extra 1 GB performance, because I run really memory-eating apps! .
