I only learnt to do a basic debug during the course of this problem, so I'm definitely no expert. The BUSCONNERR (bus and interconnect error) would explain the crashes, but googling shows so many...

Updated BIOS. Didn't help.

So I figured it was either the CPU or Mobo. CPUs are less likely to fail so I bought a new mobo.

Result: Success! The computer works perfectly now. I had almost given...

I ran Prime95 under Safe mode. Resulted in a crash D:

So I guess it's down to motherboard, graphics card or CPU.

sigh...

FUUUUU-

I replaced the hard drive. It crashed during Windows install. I tried again and I got it installed. However, the crashing is now even more frequent. I can be in Windows for about two...

I ran the HD diagnostic utility from UBCD on my hard drive. It found several errors.

C:539 H:1 S:1615 Error: Media error detected
C:1991 H:5 S: 634 Error: ECC error

Re-seated CPU heatsink - still crashes.

Ran Memtest86+ off UBCD - no errors after 3 hours and 5 passes. I'll run it again overnight to be sure.

Ran Mersienne Prime test off UBCD - crashed after...

I'm convinced that video streaming causes reboots. It's happened too many times now for it to be pure coincidence.

I also got a bluescreen twice. One was on long enough so I could read the text....

I have a rather annoying problem. My PC is rebooting a lot, without giving any BSODs. This happens when I'm moving large files, when playing certain games and sometimes when streaming videos...

A couple of weeks ago my computer began to either freeze or reboot several times a day. I noticed that it occured especially during some tasks, such as moving large files from one partition to...

Woke up this morning to find that programs take several minutes to start up. Google took ages to do one search. I first tried to update Spybot, but it came up with a "could not find update file"...

Oh wait, it was Google's fault!

Every single page I try to enter via google, be it wikipedia or youtube comes up with a "Warning- entering this page could harm your computer!" Yahoo and other search engines work fine. Is this just...

Virus or unwanted program 'TR/VB.BG [trojan]'

Looks like it to me.

Avira is still coming up with a message about the trojan being in C:/System Volume Information...

I imagine I should flush System Restore?

Thanks for the quick reply. Avira came up with alerts constantly, but the second scan appears to have fixed that.

Although Malwarebytes log says "no action taken", I did delete all of them and...

My brother showed me pictures he took on his travels on India, unfortunately he managed to pick up a trojan or worm of some sorts on the hard drive and passed it on to this computer. Avira came up...

Last year I purchased the parts for a new computer and had my friend stick it all together. In the past few months the computer has showed slowing, the loading of Windows takes more time and so on....

I've noticed some spyware processes recently which I've deleted, but I'm no expert so I'd just like to check that there's nothing else in my system. Thanks in advance.

Nope, only have 1 drive.

And yes, Windows is genuine. XP with Service Pack 2.

It appears that norton has quarantined the file. I don't know wheter that changes anything but the more you know the better.

I'm trying to fix my computer after my brother managed to mess it up. Currently WindowsUpdate is giving me troubles. It downloads all the updates but is unable to install them (and won't give an...

I've noticed. One month left of updates and then I'm changing.

Hijackthis deleted the file you pointed out, but I was unable to find the pqvpwbqa.dll in safe mode and vundofix didn't find anything...

Norton has alerted me quite a few times now about "pqvpwbqa.dll". It cannot be repaired, so it has been blocked from usage. Anybody have any idea what is going on here?
