About a week ago my computer just started randomly rebooting itself. I play an online game and noticed at one point that sometimes it wasn't actually rebooting, but the video was just going out. I figured that there might be a problem with the vid card so I took it out and am using the onboard vid but the problem is still going on. At one point it would reboot, and as soon as I selected a user account to log into in Windows it would reboot again. This has stopped for the most part, but now there are more problems.

I'm noticing now that I can no longer have multiple users logged into Windows at the same time. I am also unable to access many websites that I would normally have no problem with as I frequently surf them, sometimes multiple times a day. I have some programs that just don't open anymore either when I double-click them, though I can see the computer is processing the request to open it.

I have run Adaware, Spybot S&D, Microsoft's Antispyware, Norton AV, Norton's 1 Button Checkup, Errorkiller, and numerous memory tests to find that there is no problems.

If there is any other information (which I'm sure there is) that anyone might think is useful for me to supply to get a better idea of what's happening here please let me know so that I can provide it. Any suggestions on what I can do next to try and resolve the issues would be greatly apprectiated.

For and anyone arriving here later: before doing a full reinstall, capture the diagnostic evidence that makes post‑mortem troubleshooting possible. The items below are a compact, practical checklist that often tells whether a problem is caused by system files, drivers, hardware, or the network.

Start with logs and integrity checks. Open Event Viewer (eventvwr.msc) and examine the System and Application logs around failure times. Use Reliability Monitor (perfmon /rel) for a timeline. Enable and save Windows minidumps if kernel crashes happen, then analyze them with a tool such as BlueScreenView (NirSoft BlueScreenView). Run sfc /scannow to repair system files and chkdsk C: /f for disk problems (SFC docs, CHKDSK docs). Export any Event Viewer logs and collected dumps to external media before making major changes.

Quick command checklist:

  • eventvwr.msc — check Application and System logs
  • perfmon /rel — reliability history
  • sfc /scannow — system file check
  • chkdsk C: /f — disk surface/logical check
  • netsh winsock reset and ipconfig /flushdns — network stack reset

Drivers and hardware: use Device Manager to check driver versions and roll back recent updates. For graphics problems, a full driver cleanup with Display Driver Uninstaller can remove leftover files (DDU on Guru3D). If a specific driver looks suspicious, run Driver Verifier to stress it (caution: this can induce crashes; see Driver Verifier docs). Reseat components, test with a known‑good power supply or boot a Linux live USB to separate hardware faults from Windows issues.

If network anomalies appear, capture traffic with Wireshark to see where connections fail (Wireshark docs). Before wiping a machine, run an offline rescue scanner and back up user data and activation keys. Collecting the logs above will make any future support far more effective.

I want to add, other machines here at home are able to access those same websites with no problem.

Well... with no answers/suggestions yet, I decided to just re-image my machine using the Recovery CD and it appears that everything is fine now. So I can't say I fixxed the problem since I never found out what it was, but it's fixxed.
