Hi everyone! So here's my problem...I've been having issues with crashes for a while. I finally figured out that the CPU was overheating due to worn thermal paste so fixed that, however the PC kept freezing randomly and my Nvidia graphics driver kept crashing. I also noticed an svchost process was using up heaps of memory. A google search led me to the Malwarebytes site with a post about a bitcoin miner using up heaps of memory and creating heavy load on the GPU which I figured could be my problem. I ran RogueKiller 64, Malwarebytes Anti-Rootkit then Combofix the same as the instructions in the thread. Combofix removed three files, two of which were temporary files but I don't have access to the log to know exactly what they were. After I finished running Combofix my system started freezing up even worse than before so I did a reboot. It booted up slowly the first time but no signal was getting to the monitor. Now it doesn't seem to boot at all. Having just read the posting rules on the site after I realise now that running Combofix was probably a stupid idea but is there any way to repair whatever I've done to it? I'm running Windows 7 64 bit as well. Thanks for help in advance.

Hi SunSoar9014, :)


My name is Valinorum and I will be the acolyte today. Before we proceed, please, acknowledge yourself the following(s):

  • Please do not create any new threads on this while we are working on your system as it wastes another volunteer's time. If you are being helped/have solved the issue/no longer wish to continue, notify me in your reply and I will quickly close this thread. Failing to comply will result in denial of future assistance.
  • Please do not install any new software while we are working on this system as it may hinder our process.
  • Malware removal is a complicated process so don't stop following the steps even if the symptoms are not found. Keep up with me until I declare you clean.
  • Please do not try to fix anything without being ask.
  • Please do not attach your logs or put them inside code/quote tags. Do a Copy/Paste of the entire contents of the log file and submit it inside your post unless directed otherwise.
  • Please print or save the instructions I give you for quick reference. We may be using Safe mode which will cut you off from internet and you will not always be able to access this thread.
  • Back up your data. I will not knowingly suggest your any course that might damage your system but sometimes Malware infections are so severe that only option we have is to re-format and re-install the operating system.
  • If you are confused about any instruction stop and ask. Do not keep on going.
  • Do not repeat the steps if you face any problems.
  • I am not an omniscient. There are things even I cannot foresee. But what I know took years to learn and perfect the skill. This site is run by volunteers who help people in need in their own free time. I would ask you to respect their time and be patient as sometimes real life demands our time and replies to you can be delayed.
  • Privet Message(PM) if and only if I have not responded to your thread within three days or your query is offtopic and personal. Do not PM me under any other circumstances. Your thread is the only medium of communication.
  • The fixes are for your system only. Please refrain from using these fixes on other system as it may do serious damage.

Note: Please, bare in mind that I am still a trainee and my replies need to be reviewed by my teachers before I post them to you which requires time as both teachers and helpers are volunteers here. Take it as a good thing because now you have two people examining your problem. I really hope that we will be able to send you home with a smile on your face. :)
