Red Line Appeared on Wallpaper

I have been having numerous problems as of late, with my computer simply turning off and then rebooting all on its own. I have run numerous virus scans, spyware scans, etc.(I also went through and ran everything from the thread on this site regarding malware) and thusfar my problem is unsolved. I don't even know if malware is my issue, it may be something else, perhaps hardware related. My latest problem is that when my computer last died and rebooted itself(this time right before it died, a BSOD did pop up, but then it turned off too fast for me to see what it said), I played some Counter-Strike Source right after it rebooted, and then when I closed CSS, I noticed a large red strip on my wallpaper. I thought it was my monitor, but switching to another desktop proved it was only on that particular wallpaper. I checked the actual picture file that the wallpaper was from, and even IT now had the red strip on it. What in the world could cause that?

 

A bit more info, I just rebooted. When I got back into Windows, it acted as if i had no video drivers, but it was actually even worse than when Windows falls back to its own drivers. It was on a VERY low resolution and had what looked like 256 colors. I rebooted again, and that problem was fixed. This time, the taskbar, and all windows, were set to classic mode(this is an option for Windows overall Appearance, usually there is a Windows Classic Style and a Windows XP Style option; in this case, the XP option didn't even exist). I rebooted again, and the graphics error happened again, so I rebooted one more time, and everything was normal. The red line was also gone now. I should mention that both of these problems(the classic view and the graphics problem) have happened to me numerous times lately, rebooting eventually fixes things.
Also, I have tried to run the free ewido scanner a couple of times, and it finds something called Backdoor.Genlot.DX. It hadn't removed it though, because each time, my computer shuts down before the scan completes(I could also never complete a scan with AVG for the same reason, all other scans run fine). A moment ago, I found that I could stop the scan right when the backdoor was found and tell it to remove it, so I did. I don't know if this was the problem all along or what, I'll mess around and see if it reboots on its own anymore.

 

Ok, I have gone through that entire thread, and none of the scanners seemed to find anything wrong. I have included the scan log from HijackThis and Bitdefender for your reading pleasure. I would have included the one from Panda ActiveScan as well, but I could not find a way to save its log(the scan found nothing anyway). I have also run a couple of the scans from the Alternative Scans thread. As I was running one scanner, my computer shutdown and rebooted again, so apparently my problem is not yet solved.

Does this sound like a hardware problem or a software/malware problem?

 

Are you overclocking your video card, ram or cpu? Just curious.

From a quck scan of your logs, it appears clean. Though, I'm not an authorised malware fighter.

I'd love to know what that BSOD error was:

Right click on "My computer" select properties, advanced tab, press settings under "startup and recovery", uncheck "automatically reboot". Press ok, ok.

If/when the blue screen comes up again, please post all info here.

Also, do you have any files located within: c:\windows\minidump?

 

Nothing is OCed save for my video card, but it was OCed when I bought it. So I haven't OCed anything myself. Ok, I did that, I'll see what the next BSOD says. Dunno how long that will take, since only rarely do BSODs occur before the reboot. There are 4 .dmp files in the minidump folder, how would I view them?

Also, do you overclock?

 

Nope, in my previous post I mentioned that I don't, although my video card came OCed by the manufacturer. Also, I just shutdown my computer, bought a new hard drive, and booted to a Kubuntu live cd. I then ran memtest on said cd, planning on installing kubuntu on my new hard drive afterwards. Memtest found thousands of errors in my ram though! As far as I know, memory resident viruses can't stay in the ram through a shutdown, so I am thinking I have bad ram, am I correct about memory resident viruses?

 

Ok, I took out one stick of ram, tested it, and then switched it with the other and tested it, then repeated that process again. One of my sticks of ram has gone bad, and I'd wager that's the cause of all my problems. Since I removed the bad ram, I've been able to install Kubuntu on my new hard drive without a hitch.
