Thanks from the start. Here we go! I own a HP pavilion g6-1b79dx, its running windows 7 64 bit , its got the base hardware and is 17 days old. I with-puredata -a music program and some recorded music on it, Kaspersky anti virus, audacity and some mp3s as all I had added to it. On the 14th night the computer locked up with just firefox open, the screen had vertical and horizontal flickering lines on it. I could not get the computer shutdown with the power button so I unplugged the ac adaptor and removed the battery. At first, after the shutdown, the computer would not turn on; the power button would light but not stay on and the caps lock was flashing but I dont remember the code ( I didnt learn about that being a code until afterwards! It seemed to be continual flashing in singlets if that helps.) Looked like hardware to me, but the further evolution has led me to second guess this hypothesis.
Finally the computer came back on, at this point Kaspersky popped up saying all of its databases were corrupted and that it couldn't run and there was a possible infection on the computer. I tried the 'boot disk' from my kaspersky disc as a way to disinfect and just got a lot of restarts out of it. After restarting it would ask whether I wanted to repair windows or not, I generally hit repair, the computer would restart ( as it said it would) but sometimes ask the repair question again. Finally I got into windows and got it working, but I couldnt get Kaspersky to operate even after re-install, the restore funtion in the control panel would not restore the system to factory defaults (advanced options menu wouldnt even open). This pattern of restarts is still continuing but it is happening less frequently.
Ive restored the system twice since, kept it offline except when in safe-mode with networking and run a dizzying array of security programs. When I run malwarebytes, norton, cccleaner, OTL, spybot search and destroy, the norton internet scans, sophos and all of them come back negative. Also 50% of the time a scan causes the computer to restart. After the first reinstall a scan caused kaspersky to go beserk a second time, after the first system restore, and caused norton to go beserk after I uninstalled kaspersky and tried it with Norton.
The computer also freezes, occasionally, in the middle of running some of the diagnostics at f2 during the laoding screen. It seems to complete the battery test, and has passed run test once, but crashes on memory then has no log of that crash. When the comp crashes at f2 it displays the same patterns of vertical and horizontal green lines as it did at the first "freeze" and the screen freezes; sometimes it restarts itself from here and sometimes it doesnt.
Currently I'm running the minimal disk image restore, I have no anti-virus loaded, except spybotsearchanddestory on, which has run clean with no infections, and I am using safe mode with networking. I can get other programs to run, I've downloaded puredata again, but they also crash intermittently with the hard reset and safe mode option. I can't tell if this is a virus, bad hardware or a software conflict but all the bleepery witht he virus programs and their not being able to detect anyhting makes me suspicious and confused.
I'm pretty much trying to determine if I should give up the malware hunt and send it back to HP to get serviced, I wish it had happened on the 13th day after purchase, not 10 pm on the 14th.
Thanks to anyone who reads this novel.
