Here’s the problem and sorry it’s long winded,i’ve upgraded one of my systems and decided to give the old pc to my son. This system was used for CD Burning etc and nothing else and I never had any problems with it at all,until now…
The system spec is
512mb SDRam (100mhz)
QDI Advance 9 Mobo (VIA Apollo Pro 133)
Maxtor 20gb HDD (IDE1 Master)
Albatron GF4 MX440 VC
On Board Audio (Enabled)
Aopen 56x CD ROM Drive (IDE2 Master)
D-Link DFE530tx NIC
Additional Fans Etc
The system was transferred from tower case to d/top and a clean install of WinXP (Legit) was installed.
The problem is that every so often the system will loose the CD ROM Drive,checked in My Computer,no icon,device manager,no CD ROM drive,the shortcut icon on the desk shows CD ROM drive with ? (question mark in it)… Reboot the system and the drive reappears maybe last for a few days and then dissapears again. Only happens if CD ROM drive is in use ie games being played etc.
I’ve done the following
Checked replaced IDE cable
Updated to latest VIA 4in1 (4.43)
Removed the registry entry for upper/lower filters
Run the CD ROM Drive in PIO Mode & UDMA
This system has not had any CDR/W mastering software installed,no ASPI Layer updates etc…
I read somewhere that I should try disabling the ACPI in BIOS which I did and with this disabled the system will not boot up…? Reenable it and the system boots ok.
Has anybody got any other ideas
