My computer is being super-laggy!

OK, so my computer had a complete meltdown the other day... right after Windows 7 failed to boot, my Linux started having kernel panics and freezing every 5 minutes... so I backed up the Windows partition's files, and wiped the drive (By wiped I mean I deleted the partition, I didn't use a "disk wiping" tool)

Well Linux reinstalled perfectly fine, so I figured it wasn't a hardware failure like I thought it could be... I even used the memtest feature for several hours and it all came back fine.

Well, I reinstalled Windows 7 not once, not twice, but THREE times. The first time, I put all my Windows files back right away (including the Windows folder), but it still had the brand-new look and not my old settings so I wiped it. The second time, literally 5 minutes after I installed it, Windows Update froze up right after installing my Wi-Fi drivers and locked up the entire computer... and after force-rebooting it it became super-sluggish like it was before I reinstalled it (like when I posted on here last time)

This most recent time it worked correctly, but it still doesn't seem to be as fast as when I first installed it. If I plug in my external hard drive with the Windows files, it seems to lock EVEYRTHING up... almost as if my old Windows partition was cursed or something. I deleted the "Windows" folder from it so there was nothing possibly corrupted there, but it still doesn't seem to be perfect.

Well, even with it unplugged, it's frozen up several times now. I only had maybe 3 programs running at once... it's not like I was overloading the computer. I just tried installing Paint.NET and it completely froze my computer twice and now the installer simply won't run. What's even weirder is I did a "chkdsk" from a command prompt, and while it found nothing wrong with my disc, it stopped around 65% and sat there for several minutes. Same as before I wiped out my drive.

I tried sfc /scannow and it terminated at 14%, saying the service couldn't complete...

I might try that again in safe mode, but still, something is still messed up with Windows. Does anybody have any ideas? I mean, would it be likely there's some bad sectors on my drive that Windows can't find? Would defragmenting help? I guess I just don't understand what's going on... I've wiped the drive a few times now and it's still not working perfectly.

I would guess a RAM issue. It's possible that your Linux box just isn't allocating memory into the same areas of RAM or using as much RAM so you might not be noticing it.

Hi I would guess 64 bit and not clean installed, right? DO you have the vista dvd for a repair install?

Ken

I got it through MSDNAA and it's the 64-bit RTM.

I do have a Vista disc... but why? I did a clean install, several times too. And between each one I deleted the partition in Linux so Windows just saw empty space there.

Is there a way to do a memtest in Windows to see if it is indeed a RAM issue?

I'm pretty sure Memtest 86+ is exactly what I used with Ubuntu's bootloader. And it said "no problems found, press escape to reboot".

So what would it be?

More specifically, it seems that if my laptop's screen turns off, it freezes up once I "wake it up"... but still, that shouldn't happen. It never did before.
