Hi all,
I've been having problems with the computer I use to make a living and it's been getting progressively worse over the last month. I built this rig myself and it behaved perfectly for about 18 months. Now this. I'm beyond my ability to know what to do and I'm in serious trouble as I can't afford to replacing anything that doesn't need replacing right now.
The initial symptoms were that my WIRED USB mouse would just stop working for a few seconds at a time randomly. I couldn't tell any real pattern behind what caused it other than once it would happen once the likelihood of it reoccurring in the next few minutes was substantially higher.
It continued to get worse and worse until eventually when it happened my keyboard would lock up as well though the mouse always seemed to trigger it. At some point one of my two monitors started to flicker during boot (would start in the BIOS and keep flickering until about 5 seconds after I'd log in to Windows).
Things I've tried (in order):
Malewarebytes and MSE scans came back clean.
Restoring windows even though there hadn't been any real change.
Updating my motherboard INF chipset drivers.
Reverting those drivers back to factory defaults.
Reformating and doing a clean install of windows 7.
Buying a PCIe expansion slot USB controller and doing another fresh format/install and running my USB devices through the card.
Buying an entirely new motherboard and rebuilding my PC keeping all other components, once again reformatting the HD.
I'm still getting the error.
I'm at my wit's end here. I do have another HD attached that I didn't format because it has a few hundred gigs of work files on it and I don't see how a virus could be doing this if I've formatted the drive the OS is actually on and both motherboards were set to boot off the formatted drive. Not to mention Malware bytes found nothing at any stage of this and I don't download things or visit shady sites.
I didn't think a peripheral could fail in such a way that it would wedge the USB entirely and the mouse seems to be working perfectly aside from when it fails entirely. It's a Logitech and not that old. Keyboard was a well reviewed mechanical. Also running a USB WiFi adapter, but again, that's been in use for a year and a half without issue.
I'm suspecting possibly a really weird presentation of a power supply failure might be the cause? I can imagine unstable voltages causing USB controllers to hiccup and possibly causing the flicker on my monitor on start up? The thing is, then I'd expect to have issues on the rare occasions I have time to game since then my system should be drawing a lot more power and it hasn't been an issue.
Processor and RAM failure I'd expect a lot more BSOD and a lot less repetition in the nature of the failure...
Grasping at straws here. If anyone has any ideas on how to diagnose this or eliminate possibilities I'd be seriously appreciative.
