fixing up an old hp compaq nx9110

hello, i'm working on a compaq nx9110 laptop. this thing will randomly disconnect usb ports and the devices in them. the wireless connection won't work for some reason (the pci modem in device manager has an exc. point beside it), and the cursor changes to random places when i'm typing. my avg free version doesn't load properly on startup. i have general slowness issues with this computer. sometimes, it won't start up at all. help! by the way, here is a pc pit stop report and system event logs. i have no idea why i can't load a hijackthis log. i'll post that in the other forum.

Hi etidd… Ok… This laptop likely has a bad hard drive. It is not running in DMA mode and it is likely because the computer is encountering read/write errors on the hard drive due to bad sectors. You need to click start -> run -> type cmd and press ENTER. At the command prompt type chkdsk /r and press ENTER. Answer 'Y'es when prompted about scheduling a scan during the next restart. Now, restart your computer. Be patient while the scan completes. During stages 4 and 5 if you see message about "windows replacing bad clusters…" this will help substantiate that this is a bad hard drive. Let the test finish. Hopefully there are only a few bad sectors and everything will be OK. An excessive amount of bad sectors means the drive is bad. Now, you need to go into control panel -> system -> hardware -> device manager. Expand the IDE controllers section and delete the primary and secondary controller. It will want a restart but do not restart until you have deleted them both. They will not disappear from the list. Reboot your computer and it should revert back to DMA mode and you will see a noticeable improvement in speed. This is assuming that the drive isn't bad though. After that, uninstall AVG because it is messed up. It is causing substantial performance issues during boot up. When you uninstall it, reboot, you will see a marked improvement in boot time. Reinstall if you would like. Tell me your results and we will go from there. If the drive is bad there is no sense in continuing in the present state.
