HELP Mp Laptop has Corrupt Files !

Hi, i am new to this forum. :DI need some help. I am pretty Computer Literate, but I am in a jam here. I have a HP Pavilion Laptop, Model Dv9260us core 2 cpu T7200 @ 2.0ghz ,2gb ram twin 120gb hdd's, 256mb dedicated Nvidia geforce go graphics 7600, 17" hd display, HDDVD ROM Running Windows Vista Ultimate 64 service pack 2. My Laptop was taking about 8 minutes on average to boot,sometime 9 minutes.But Runs Great once running.also shut down was 4 to 5 minutes. I tried Defrag, CCleaner Defrag Registry,Registry Cleanup,enable both cpu's at start up,ran Avanquest's System Suite Utilities,Chkdsk/f ,and still the same.so reading on some forums, a lot of advice was to update all drivers. So I got Driver Genius Pro 9 by avanquest (Driversoft company when installed)this program found 22 drivers out of date. so I created a restore Point and did a full registry export(backup).next, I let all the drivers completely download,then First,I installed Intel turbo memory drivers,everything was functioning well, so I proceeded to install Intel chipset device software.Everything A OK.3rd was the Nvidia Display Drivers so I made a second Restore point (I had issues in the past with display drivers) So I installed the Nvidia drivers and on reboot I input my password and it says The User Profile Service service failed the logon. User Profile cannot be loaded. I tried to run Restore but it says Disk OS(C) has errors(Windows detected file system corruption on OS(C).you must check the disk for errors before it can be restored. checking disk OS (C) - Some Problems were found and fixed. But at reboot - same issue. so I went to vista forums."Brink" had some great advice I used that I found in a thread, to turn on the "Real" administrator account in safe mode to gain access and I uninstalled the Nvidia drivers under the admin acct. at reboot states corrupt system files (CheckDisk) But when I tried to run driver Genius in admin again to reverse the intel drivers (this shows up as Intel Matrix Storage Manager in Start>Programs) the PC crashed. I ran CHKDSK /f now I can boot into my acct. but ther seems to be lots of problems like NO sound device found, sidebar gadget shows no battery, sidebar gadget shows CPU cores 1 and 2 running at 75 to 100 % all the time and the fan sounds like @ full speed constantly.Also bluetooth Hardware not functioning. The Drivers for bluetooth and sound show "Functioning" in device manager. :sa:AAARGGHH Someone HELP Please as I spent many many months customizing and lots of money on software that will be lost. It seems to be fixable but where should I start as I do not want to further corrupt anything. Thank You Guys. Awesome Forum by the way.... Let me Know PLEASE
