Major Trouble Reporting, Sir!

Once again I find myself begging for assistance from you fine fellows. My problem is complex and potentially damaging to my pc. The problem begins to reveal itself as a blue screen failure when attempting to install Win XP SP 3. I have tried this several times and each time I get the same final result, memory dump and reboot. I do know now that I had a rootkit installed on my pc. I found it using "Unhackme" a rootkit removal program. I did this after I was unable to get "RootRepeal" to work. I tried RootRepeal several time and each time I tried seaching for hidden or locked folders or when searching for hidden services the program would lock up and not complete the process. I believe I waited almost an hour one time for it to break free and it ended up with a blue screen error as well. Removing the catchme.sys file with unhackme did finally restore my access to safeboot. I had lost that functionality as well. Super antivirus didn't find anything of interest. And Malwarebytes quick scan also came up clean. A later full scan with Malwarebytes reveal a couple of things and one backdoor dropper in two places. Another symtom of my pc is that it will not run Bitdefenders online scan. All other active x addons work. And, I uninstalled and reinstalled bitdefender several times. Another symptom of my pc is that now I cannot boot off of my cd. My cd/dvd works fine otherwise and I even updated its' firmware in an attempt to fix the boot problem. A reason why I would want to boot from a cd is that I have six folders on C:\ that have inaccessable folders. A couple appear to be service pack installation folders but a couple of them have only an inaccessable i386 folder or amd64 folder. I wanted to try and delete one of the folders from a boot disk like UBCD4Win v.350.

Symptoms:
Cannot boot from CD. Updated firmware no effect.
Could not boot in safeboot. Found Catchme.sys , fixed problem.
Cannot run Bitdefender online scan. Made a trusted site, uninstalled reinstalled, no effect.
Cannot install SP3. Bluescreen error
Cannot run RootRepeal. Locks up Bluescreen.
System restore not functioning. Can create a restore point but cannot restore to a point.

I am unable to complete the steps defined by this forum to return log files for each of the scans required. My sticking point is RootRepeal. I also ran "RootkitRevealer" and "Unhackme" RootkitRevealer did post a log that has some questionable items on it but as I cannot gain complete control over my system I am stuck. I cannot do a fresh install because of my lack of a bootable CD/DVD drive. Other than that my pc seems to be working fine. Should I keep messing with it till it breaks or just accept that something is screwy?
