I have an older m8100n HP Pavillion.
Couple years back I put in a BFG GeForce 9600 GT OC.
Computer has run great with no problems (i use it for gaming) and I decided to upgrade the memory today.
The stock memory on this system is 3 gigs ddr2 pc5300 - (2x1g and 2x512mb).
I have windows 7 home premium 64 bit installed so it would recognize the additional memory.
I purchased 2 sets of 2x2 pc6400 g.skill memory for 8gigs total.
When I installed them, no post.. boots up fine (i.e. fans spin, harddrive spins, cpu fan spins) but no post.
I took out the newer memory thinking I did something wrong and put the old memory back in.. still no post.
Spent about 4 hours pulling out hardware putting it back in making sure everything was tightened correctly etc. Tried booting up with single sticks of memory to detect one bad one for RMA... nothing.
Won't even post with a single 512 stick in..
I could use help on this one.. PLEASE don't tell me it's a bad mobo!! haha
take out the 2 gigs of ddr2 out leave in the 512 mb sticks in in there original location to return it to its original state then install your graphics card try boot up then if the same problem occurse try to jump your cmos with the graphics card still in there should be 3 pins with a cap on 2 of them put the cap on the pin that hasn't got the cap on it connecting the middle one also then try boot if the same thing happens take your cmos battery leave for 30 seconds put it back in a boot up hope this helps
kind regards skarin
The memory does match computer manufacturer specifications. First, reset BIOS to see if that helps. If not, you may need to try different hardware to see what is causing the problem. Keep us posted on the results.
