Hi all. I'm running XP. My computer first started freezing recently and I found that dumprep.exe was taking up nearly all my cpu performance. I followed instructions from this page and removed it from startup. It seemed to solve the problem until my current problem started.

When I turn on my computer it lags after the XP screen [with that little horizonal blue bar] for a good while, maybe a minute? It'll just be a black screen, then my monitor's power indicator light will blink, like when the computer is off but the monitor is still on. In addition to that, programs like firefox, aim, and photoshop have been crashing quite often. I get that "This program is not responding....end task" window and I'll try to end task but it'll stay open.

I've run my antivirus, adaware, spybot, ccleaner, etc...and nothing has shown up so I don't think it's spyware or a virus. I tried doing a system restore today and it says the system restore was unsuccessful. I tried a few dates and they all didn't work.

Does anyone have any ideas about what's wrong? any and all help would be greatly appreciated.

Items in blue which are underlined are clickable to give more information about the process

Click start then run, type prefetch then press enter, click edit then select all, right click any file then click delete, confirm delete

Click start, all programmes, accessories, system tools to run disc clean up, click more options, clean up restore points, click OK, then from system tools, run disc defragmenter.

Click start then run, type sfc /scannow then press enter, you need the XP CD and Windows File Protection will show a blue onscreen progress bar, when the bar goes, reboot

If you do not have an XP CD you can borrow a same version as was originally installed XP CD, if you downloaded SP2 then you need an SP1 XP CD

Click start then run, type chkdsk /f /r then press enter, type Y to confirm for next boot, press enter then reboot.

Windows will appear to load normally then either the monitor will show progress or the screen will go blank, do not disturb this.

This will take an hour or so before it gets to the desktop.

Download and install Tune Up 2006 Trial

Run Tune Up Disc Clean Up

Run Tune Up Registry Clean Up

Click Optimize and Improve to run Reg Defrag, which will take a few minutes and need a reboot. You should disable the antivirus programme to run this and check it is running after the reboot

After the reboot, click optimize then system optimizer to optimize the computer, select computer with an internet connection from the drop down menu, this also requires a reboot

After the reboot, click optimize then system optimizer to accelerate downloads, select the speed just above your actual connection speed, this requires a reboot

After the reboot, click optimize then system optimizer to run system advisor
