Well the computer started being a bit slow, its a Gateway MX6448, and it's about 1 1/2 years old, it has a LARGE amount of useless programs I've downloaded, so I decided, i'm just going to reformat it, nothing on there that I really would be unable to regain, I did that with the OS disc that came with the computer, I had it reformat the hardrive, and reinstall the OS, after a couple of days the computer started blue screen crashing a lot, and I decided, well, reformatting is the solution to all problems, so I tried to reformat again, only this time after reformatting the HARDDRIVE, the computer blue screened while reinstalling the OS, giving me the error " IRQL_NOT_LESS_OR_EQUAL " , and it does this everytime I try to reinstall the OS...At what point in the installation do you get this error?

Do you know if the disks that came with the computer include drivers for the motherboard and / or chipset?After the hard drive is formatted and reinstallation of the OS is taking place at various times,. sometimes 1%,5&,EVEN 60% COMPLETION, the error will come about, but it always does.

And im not sure if the CD contains the drivers.I would do a memory test - Link > HTTP://www.techspot.com/vb/topic62524.html

I would also test your harddrive using diagnostic tools - These tools are normally found at the hard drive manufacturer's web site.

You could also try reseating your ram.
