Weird Computer Problems

**smidsy** · 2nd June 2013, 10:24 AM

Ok this has got me stuffed.
The PC is left on always for certain activities, got up this morning, the keyboard wouldn't work, just beeped and the mouse was doing odd stuff like bringing up properties instead of image viewer when I clicked on an image and save as when I tried to click on a book mark. Other functions wouldn't work with a mouse click - send/receive in Outlook for example.
System restore didn't work, different keyboard and different USB ports for the same keyboard didnt work. Tried an over install of Win7 but it wouldn't let me.
Ran AVG (a trial version) but that found nothing.
Hooked up an old XP installed drive to format that and install Win7 but it wouldn't let me.
Finally gave up, decided to plug the Win7 drive back in and do a format install (a last resort because I'd lose 700meg of data) but when I rebooted everything's fine.
The only other thing of note is that to do the system recovery I completely uninstalled AVG.

Could AVG have been the issue?
Anyone got any idea's on this?
Cheers

Did you reboot before the one mentioned near the end of your post?
How long do you leave the computer running between reboots?

Windows is not able to run continuously. It is recommended that you reboot regularly.

I rebooted a heap of times - pretty much as soon as I realised the problem wasnt fixed.
I fitted a new hard drive and a fresh instal of Win7 and all seems fine.
This box is 26 months old and has run 24/7 all its life (I generally reboot it every 2 weeks or so) so the hardware is very tired.
If the tax man is nice to me I plan on building a new box and will also look at a RAID box which will take some load off the computer.

The fact that it was still working (still doing 'things' even if not the right things) suggests that it was some form of software error - a registry corruption would be my first guess, which finally got straightened out by the self-check and shutdown/startup routines.

You can get a HP Proliant N40L microserver that'll run windows/linux for just over $200 at shopping express. If you really want low power, add a small SSD to it.

Well the flash problem as come back worse - no when it crashes (which seems to be about every 24 hours) I have to reboot to get Firefox back up.
This is a brand new hard drive with a completely fresh instal of Win 7, word and data (mainly MP4, MKV and music) are from the old system (I'm running 3 internal and 2 external drives) but C drive and all its software is a fresh instal.

I'd start by running Memtest86+ and leave it operating overnight. If you don't have a floppy drive you can create a bootable CD.

Memtest86+ - Advanced Memory Diagnostic Tool

that sounds like hardware issue (becuase of the beeping). possible card/usb port failure. move both the keyboard and mouse to front usb ports if you have them (to test) and see what happens. if it is ok, then buy new PCI card for the box

Arrr me hearty, a box "doing certain things" and let on all the time. Avast!

Strykerblo is right. I suspect a good old fashioned buffer overflow. I see this sometimes on hard working north/south bridges...

My guess, heat. Pull off the CPU cooler, bus cooler and GPU cooler and re-gooze those suckers. Blow out the fug from them too. Clean the PSU with compressed air (I use my garage compressor!.... Pwwwwffftttt!)

I have seen this on GPU SETI boxes and heavy use DB RAID systems with crappy controllers. They go loopy sometimes.
