BSOD (dumps attached)

After opening some corrupt software last night, my task manager got disabled and my computer started to lock up. I immediately rebooted in Safe Mode and ran HijackThis to remove any suspicious startup programs.
After doing these, I rebooted into windows and logged in. However, shortly after logging in I received an IRQL_NOT_LESS_OR_EQUAL BSOD, I then rebooted into safe mode and once again got the BSOD. I then decided to remove one of my two RAM sticks but I still got the error, same thing happened when I tried using only the second RAM stick.

I then decided to boot into repair mode and ran the hardware test which gave me no errors. A few minutes ago I logged in again and this time I received a SYSTEM_SERVICE_EXCEPTION BSOD. I tried safe mode again and this time, it is working fine so I am now able to acces the dmp files.

Most of the BSOD's seem to have been triggered by ntoskrnl.exe but there are also some other erroneous files.

Since I can't install WINDEBUG at this PC, nor know how to properly use it; I have attached my dump files to be analysed.

Thanks in advance,

Worked for a while in normal windows but now it gives me a "DRIVER_IRQL_NOT_LESS_OR_EQUAL" BSOD.

Sorry to bump again but I urgently need some files from my computer.

Everyone advised me to go to this forum but a day has past and I still haven't received any help. This is really urgent so I am once again begging someone to take a look at my dumpfiles so I can get to know if it's a hardware or software failure.

im like u guy, im really tired of this. i think it is better to kick our graphic cards huh? if u r in tell me to do together!!!!!!!!!
