CPU/Mobo IDE/SATA devices not detecting randomly

[satyanjoy]

I am facing this strange problem,sometime, while booting my pc took long time to detect the ide/sata devices and sometime not detected at all,, I have total 4 devices - 2 sata hdd and 2 sata optical drive,what may be the problem

Check the cables, both the power as well as the IDE, if there seems to be any fault, replace the cables.

If problem persist, then try connecting the hardware one-by-one, to find the faulty one

Could be due to PSU, I had same problem after trial and error got to know that my PSU is faulty.

i called up tech support,, they changed the cables and cleaned the entire system,,now its booting ok,,but bit slower

Usually, its the cables. If the issue persists, clean the contact. Another thing that can be done is to use a PCI card and see if the issue persists.
