6400 Laptop, i have done a virus scan and found nothing, i would really appreciate help from some kind people.
Thanks in Advance.

I have been running windows 7 for 3 weeks with no problems. Then a few days ago it slowed down for 5 minutes at a time to the point of almost freezing. Now it is basically not working.

I have a 1500 dollar home built pc from about 4 months ago so its not that my computer can’t handle it. I suspected it was a virus so I did a virus scan but nothing came up.

I now need to check the registry but what is the best windows7 compatible safe mode registry cleaner? I can only run safe mode as regular mode is broken.

My PC has recently sprung a new problem on me that I can’t solve. I am by no means a noob but this has got me baffled!

I am using Windows Vista with Intel Core 2 Quad CPU

The problem is that my PC will turn it’s self off for no apparent reason… I can be doing my normal work at my PC and it just goes off, no "Windows is Shutting Down" message no logging off message, nothing, just turns it’s self off.

If I try to turn it back on it wont boot up, I need to wait a few minutes before I can turn it back on (this suggests to me that my PC turned off as a precaution as my processor was over heating but I don’t know to be honest)

It started to happen more often so I ran Windows task manager to see what could be pushing my CPU so hard… nothing obvious there but all 4 cores were running at 100% when my PC turned it’s self off again so I’m pretty sure my PC is turning off because of it but I don’t know what is causing my CPU to run at 100%

I’m running a lot of programs at the same time I must admit but this was never a problem for my PC (at most it would use 80% total CPU for the same amount of open applications and that really is at the very most!)

Needless to say I have ran a virus scan and nothing come up (NOD32 anti virus)

I have also used CCleaner… Run Reg Cure and Registry Cleaner, Tune Up Utilities 2009 and Malwarebytes’ Anti-Malware… none of them helped even a small bit.

Stupidly I deleted my restore point that was created before this problem started so thats not an option.

I appreciate any help as always.

Explorer’ it starts to open my Yahoo homepage but stops before the page has loaded completely, then It says internet explorer has encontered and error and needs to close. I have tried everything including virus scan, registry cleaner, deleted history, etc, etc. Antone have any suggestions? (besides take the computer out back and shoot the dang thing)
I did system restore, and installed IE7, and that didn’t help.

My Dell Latitude came with XP Media Edition, and I do not have an original disc. It has slowed to a crawl, I get error messages on opening apps, and nothing helps (clean disc, virus scan, spyware scan, clean registry). My only recourse is to start anew. I have an XP upgrade CD, but I want to re-format and do a clean install.
