I reformatted the hard drive on my Compaq Presario 5240. 1. My modem now is not detected (new problem). 2. Two CD-RW drives are not recognized by Easy CD creator (recent pre-reformat problem) but application disks play on these CD drives. 3) I cannot download a flash card 98SE driver (never tried before reformatting). On the device manager screen, I now have yellow question marks next to "flash drive", "PCI serial controller" and "PCI universal bus controller". That the flash drive yellow question mark comes up when the stick is plugged in is evidence that the USB ports are working and the flash drive is identified. I have tried several brands of flash drive and their respective driver download sites, each time failing to get the flash drive to work. When I remove each individual device manager PCI identifier that has a yellow question mark and reinstall the component, the installing dialog box says a driver is not detected. I have used IE6 and IE5 to attempt the download, in vain. I have used two browsers - Explorer and Netscape 7.2. I would appreciate help identifying the communications problem here. I contact Compaq about the modem and PCI yellow ? marks. They sent me a patch, but a file seems to be missing "windows\system\infunist.exe". The 4 rear bank of USB ports (all now working for other purposes) I installed myself some years ago. I also installed the second CD drive. These drives are LITE-ON LTR 24102B and LITEON CDR LTN 382. The Presario 5240 otherwise works well and I would like not to have to replace it. Thanks. PS: I would also like to know what I must do to use a flat panel manager, which won’t work at present.
