HELP!A new virus generation?

[Violent potatoe]

Hello everyone.Yesterday my PC got infected with a virus that disables Task manager,regedit and doesn't allow me to install any program or antivirus,thus I can't check for viruses.Anyways i managed to find out that there are two unknown processes running in the task manager(I can open it from gpedit.msc from run but in a second it closes again)named:winxprrxx.exe and winxjsgv.I cant simply delete them as they can't be found on my PC.But when I formatted C and installed a fresh OS i found myself beeing unable to open task manager again(thought it was on D as well and wiped it too),so now i got 2 absolutely clean disks but virus is still here.Could it be that a virus is in the RAM or it downloads to my computer when I turn the modem on?I can only rely on professionals on this site to help me as i am unable to do anything.

Here's a Hijackthis log file:

Please reboot your computer in Safe Mode by doing the following:

1) Restart your computer

2) After hearing your computer beep once during startup, but before the Windows icon appears, press F8 (Repeatedly).

3) Instead of Windows loading as normal, a menu should appear

4) Use the up arrow key to highlight Safe Mode and press Enter.

Please run HijackThis and click "Scan". Place checks next to the following entries if still present in the code and close all browser and other windows except for HijackThis, and click "Fix Checked".

Rename hijackthis.exe to inferno.exe and post a new log, also tell me the condition of your PC.

I cant do that,because when I try to run windows in safe mode a blue screen appears and then the computer restarts
