Please find attached; root repeal report (only drive C:\. When I tried to include the 80GB backup drive it crashed) the Mem32Kdiag screengrab of it crashing and a zip of all the minidumps. I'm using bluescreenview, SEVERAL free malewale and rootkit scanners & trendmicro online.
I'm fixing a PC. It first presented with multiple bsod's, virus infection, very corrupted hard drive & a VGA mode video distortion error. I called it "Pixel swipe"; it looked like someone took a rake and swiped it across the screen. It only happened during boot or when in the BIOS and only when it was running for a while. Imagine a XP splash screen, made from sand, being raked from right to left. Thatís kind of what it looked like. I took pictures and could post them it needed. I updated the Nvidia drivers. That seemed to fix the video errors. I ran Seatools for the drive, memtest for the ram, I ran housecall.trendmicro and removed the infected files, ran several root kit / maleware / antivirus scanners. I ran check disk with sector recovery (it has no bad sectors), I removed all freeware and installed Norton 360 v2.5 and installed an older 80GB HD as a Backup drive on E:\. Updated the drivers & made sure the OS & all running software are up to date.
I returned the PC and it came back a week later with 3 bsodís. The video was all distorted again so I replaced the video card with an older, less demanding PCIx ATI Radeon card. Ran chkdsk again (came up with corrupted files) and returned it.
It ran fine for almost 6 weeks.
Now the bsodís start again. First few at 4 Oíclock in the morning so they go undetected by the end-user. Then they get a whole bunch while they're using it. After questioning I determine the only common occurrence is that Firefox is running every time. I leave FF running with multiple tabs open and I eventually start getting multiple FF crashes eventually leading to a black screen (would not come out of sleep) and upon reboot I find it bsod'd last night.
Here is everything I think you guys need (according to the posts I've read) to come up with a possible diagnosis.
FF is up to date - hell, everything is up to date as far as I know.
This is a 5 month old PC. It has all top shelf, brand name parts. I didn't build it. On paper, none of these problems should be happening. It has passed all the hardware and software tests/scans that a experienced tech would run (I'm over 10 years in the field)
I've come up with; intermittent hardware errors caused by unknown incompatibility and I should replace the drive and reinstall all the software from scratch.
