I'd try a new hard disk. Use your recovery media to put Windows on it (on a netbook, generally an external CD-drive is necessary).
If it's a motherboard error, the new hard disk won't help. Then buy a separate enclosure and you'll have an external disk ready for use.
Upon startup before anything else happens (except asking me if I want to press f2 for setup) my aspire one netbook says:
For Atheros PCIE Ethernet Controller... v18.104.22.168(1/22/09)
check cable connection..!
PXE-E63:error while initializing the NIC
PXE-MOF:exiting intel PXE ROM
No bootable device-insert boot disk and press eny key
I then can't get anthing to happen except for it to repeat itself.
what should i do? This is a Windows XP home edition
Along with this issue when it does rarely boot up I get the blue screen of death involving the Kernal file. Any help would be much appreciated
