hi!!
i have a dual boot p4 2.8 machine with 256mb ram and asrock 845 motherboard.a few months ago my machine started to heat up and the fan started roaring.after some days, the computer started hanging every now and then.sometimes it worked for only 10 mins and sometimes without any problem for hours.however win 98 worked fine.i tried re-installing xp but the system sometimes would hang in the process of installation only.sometimes it said it could not read the disc or the disc was corrupt.
after many tries, xp would install but the problem persisted.a technician looked after the machine and said it was heating problem.
i cleaned the heat sink, fan and checked every connector on my machine.
after that, the cpu was cool but new problem arose.the bios doesn't recognise hard-disk if dvd-rw and hdd are connected to the same cable.but when i separate them, the bios detects hdd but hangs after writing..."searching for boot **** from ide ...ok". sometimes even the screen goes blank and would appear only after a few restarts. what may be the problem? i used memtest to check ram.it was ok....please help..!!!
