Slowww core i7 system

Two hours to install Windows isn't too bad. It takes time to install it. Unless you're actually running programs and having speed problems (NOT just problems with being impatient), there isn't an issue here.

an i7 doesn't make a system fast. It's ussually bottlenecked by in your case the HDD anyways.

2 hours to install windows 7 is WAY too long. The install should be finished in about 15 minutes if done from a flash drive, and about 20-25 minutes if done from DVD.

I recall seeing something in another section of the forum about i7 chips not liking certain memory configurations (if I recall correctly, the other user with this problem had a 2 x 2GB memory setup as well), but I haven't seen any proof of the claim, and haven't tested the idea out myself.

Yes, but the OP mentioned he has 1 TB hard drive, all of which support sustained write speeds of at least 85-90MB/sec.

soo what shoul i doo?? change the ram or th hdd???

Yeah but he says it has the speed of a pentium computer. I have an i7 930 an in opening browsers starting games it isn't really faster than the pentium pc my mom has. I have no idea about how long win should take but as for general seed of the computer the fact that he has an hdd ussually bottlenecks it making it only marginally faster than a pentium(only in things like opening apps it obviously beats the hell out of a pentium with things like compressing, ...)

i read in another site the a guy having the same problem solved it by using one memory stick !!! but i need the 4 gig ?!!! how can i solve this issue??

well try using one memory stick see if it gos faster. If it does at least you know where the problem is.
