Generic Card reader problem

Mainboard Asus P5L VM, intel E6420 core 2 duo, Vista premium 64 bit 2 gig ram, 250 gb sata drive geforce 8600 gt vid card.

My card reader has apparently stopped working tho I must admit I have not used it in about a month and as tower is at ground level I never noticed that power light on cardreader was not on. I don't know the name of the card reader wich was built in when I bought the system last month. I've had the card reader out to check for a name but there is none except for a barcode number. I do not recognise any names in the device manager which might point to the card reader. So I do not know which driver to look for.

I downloaded a generic driver from Driverguide but am not sure wehther to install it cos is say's os's 98 upwards to Win2K.

Anything else I can check before taking it back to the shop.

Many Thanks

i get the same problem every couple of weeks you need to unplug it then boot up into vista then plug it back in and it should work if its a similair problem to mine

cheers brad

ps i have noticed when it happens it gets halfway through the bootup and the light goes out and doesnt come back on
when its working properly the light goes out and comes straight back on
