Hello, since many pgers know that my current motherboard is b2 stepping, still it was working fine till yesterday, but yesterday my pc started giving no suitable boot device error on Startup but after 5-10 restarts it started and worked fine for a whole day and then suddenly it become so slow and as expected it was due to hd/sata port and reading speed was 0.7mb-3.1mb(checked by hd tune) when i restart, again boot error. then i changed my sata port and it started successfully and read speed went up to whopping 80mb-125mb, but it was still giving me that boot error every now and then. so i cleaned my whole pc including hd with paint brush and it booted without any error and is working fine but i'm v.v.confused what is causing this problem? motherboard or hd? if my motherboard is bad can you recommend me new one? budget is 8k but this time i want good motherboard with 2-3years warranty preferred and if hd then good 500gb hd sata 3 preferred with 2-3years warranty.
