Windows XP loading problem

[arthur5552000]

Hi friends,
I just assembled this new pc.It has a Zebronics cabinet/Intel core 2 duo/Asus P5B-MX WiFi-AP motherboard/XP Professional SP2/Seagate 250GB SATA HDD/2GB Zion RAM/Realtek HD Audio Manager.I am facing some problems with it from the very beginning.I shall be very greatful if anybody can help me to solve them.

1.Sometimes XP is not booting properly.It means it is coming to the main screen where one can see start menu/my computer etc but all start up programs are not getting loaded in the system tray .When I am moving mouse to task bar hourglass appears as if some program is running.I can not access start menu or any other icon in the desktop.Pressing control-alt-del shows no application running.If I try to shutdown from there it shows explorer.exe is not responding.Only option remains is to switching the power off.After doing switch off-on for many times XP loads normally(means I can open programs or access any folder/desktop icons etc).

This is happening 7 out of 10 cases when I am switching on my PC.I have already formatted my C drive and reinstalled XP 3 times yjinking there might be some problem with the OS.

2. I am getting this error message while booting: " Intel cpy uCode loading error". What does it mean?

3. I was getting audio output from my cabinet's front panel headphone jack. But suddenly that stopped.I re-installed Realtek deiver/upgraded it but no improvement.Now I am getting sound only from rear port in the motherboard. Realtek gives analog o/p to rear port and diginal to front panel.So I am loosing digital output.

Please help friends!!!

dear,
it might be problem with ur hardware, i.e. if they are not synchronized.
like ur memory FSB is not matching wiyh the motherboard specs.

check the HW specs of ur sys on net or with some tool sw.
