Missing Base System Device Driver  

hai all,

Before i start, please pardon for my poor English and lack understanding of high tech/computer tech..

I really need help. 2 days ago i uninstalled some programs (Eset, Hero DVD player -> my cd rom seems to be broken since it cant read any CD i inserted, Blue Screen View and AVS player, tried to uninstalled Nero9, but it keep cant be uninstalled) in my laptop (Compaq Presario CQ40, 32 bit, using Windows 7 Ultimate), and just yesterday when i turn on my laptop, i just realise that the sound came from my built in speakers (Altec Lansing) seem broken/not as clear as before. I googled how to fix this and one of the solutions i found was to uninstalled and re-installed Sound Driver. While i followed the steps to find the Sound Driver, i notice that i have 3 missing Base System Devices. And here are the Hardware IDs :

PCI bus 4, device 0, function 0
PCI\VEN_197B&DEV_2382&SUBSYS_30F7103C&REV_00
PCI\VEN_197B&DEV_2382&SUBSYS_30F7103C
PCI\VEN_197B&DEV_2382&CC_088000
PCI\VEN_197B&DEV_2382&CC_0880

PCI bus 4, device 0, function 3
PCI\VEN_197B&DEV_2383&SUBSYS_30F7103C&REV_00
PCI\VEN_197B&DEV_2383&SUBSYS_30F7103C
PCI\VEN_197B&DEV_2383&CC_088000
PCI\VEN_197B&DEV_2383&CC_0880

PCI bus 4, device 0, function 4
PCI\VEN_197B&DEV_2384&SUBSYS_30F7103C&REV_00
PCI\VEN_197B&DEV_2384&SUBSYS_30F7103C
PCI\VEN_197B&DEV_2384&CC_088000
PCI\VEN_197B&DEV_2384&CC_0880

Can anyone help me to explain what does this mean? and what should i do? does this missing Base System Device drivers could be the cause that my speakers suddenly have issue (the sound is broken and not clear like before).

Thank you for the help.

Hi Maxie,

Thank you for helping me.. Um.. i'm sorry i'm not quite sure i understand what you mean by 'Manufactures Website'. Is it means i have to go to HP website? and "some letters missing from your Model Number", what kind of letter is it? i'm really sorry, coz all i know of my laptop type is Compaq Presario CQ40 (it was shown by a ticker in my laptop). But when i was trying to fix my other problem, i was instructed by someone to post a Speecy result of my system, so i dont will this could help indetify my problem -> http://speccy.piriform.com/results/a...SIXSlGQi437WXY

Once again, really pardon me for my lack of understanding of how computer technology works.. i just use laptop to watch movies files and browse websites i use to visit daily..

dear Maxie,
I've check the website and downloaded HP Support system and follow the steps from there (my laptop is Compaq Presario CQ40-538TU). And tried to found suitable driver. But for my laptop, the operating system version that availabe is only for Windows Vista and i search each one the drivers listed but i cant find Jmicron Host Controller, the only driver with Host Controller i found was JMB38X Card Reader Host Controller Driver (in the Driver-Keyboard, Mouse and Input Devices). Please advise me for the next step.

And since at the moment my laptop is having so many issues, i tried to not download any programs, etc. Would it be fine if i uninstalled HP SUpport Assistant from my laptop?

thank you

Dear Maxie,

i've installed it. may i know the next steps? and may i know what is JMB38X Card Reader Host Controller Driver and what can it do? and what changes do i would have/experienced after i installed it.

Thank you

Dear Maxie,

Oh.. ok.. i dont know when it was changed, coz as far as i remember, quite a long time ago, i've used a card reader to access memory card i took out from my old cellphone to moved files in it to my laptop several times before. But well, i'm facing so many issues/problems in my laptop that it seems everyday i found something changes in my laptop (failed to check disk/file system C, cant do a system restore, NoScript suddenly bloked lots of websites even the sites i visit everday, and now my built-in speakers sound is also changing). I thought it could have connection with the missing Base System.. but now, i'm afraid the missing Base System could be another change happened bcoz something wrong with my system.

But, anyway, i checked and there isnt any Missing Base System error anymore. Thank you for the help and fast response.

Thank you
