Hi,

I've been through the experts-exchange db but didn't really find an answer.... So, here it goes:
My windows 7 machine keeps randomly freezing, mouse keeps working.. ie if I right click on a drive, it comes up with the annoying "not responding" message - leave it a few seconds and then it comes back with my right click menu. Youtube keeps pausing, internet navigation is almost impossible. I have noticed that if I write files on the OS hdd then it's worst...
BUT
1. when I 'kill' the 'explorer.exe' everything is back to "normal"
2. if I change OS and login to Ubuntu everything is perfect! (apart from my Raid5 not being recognized)
I have a new psu (950w) a quad-core 3,6 cpu, zalman lq1000 water cooling case, 4x640GB Raid5 hdds (Data, user folder), 1x128GB SS HDD (OS installed), 1x1,5TB Seagete HDD (backup of Raid5), eVGA 680i SLI mobo, nvidia graphics and 2 GB Ram (used to be 4...)
I have tried almost everything, even leaving just the OS hdd connected and removing EVERYTHING else but the problem is still there...

So my question is:
1. how do I test if it is my RAM (without purchasing new)
2. how do I test if it is the CPU (again without purchasing new)
3. how do I figure out if it is a Software problem (trying to avoid format)
4. could it be the solid state hdd?

Help, IT's DRIVING ME NUTS!!!!!!!!

download Ultimate Boot CD and boot the system to check the hardware including the RAM, but why did you reduce the RAM, Win 7 likes a lot, 2GB really is the minimum, and you have a good PSU, but a lot of drives. [http://www.ultimatebootcd.com/]

have you checked your system BIOS, also the solid state software/driver, as i understand some had issues with Win 7 and had to be update/flashed?  try booting with one or two SATA drives only and see if that stops the issue.

you could check the Event log (Admin Tools) just incase there is ATA/ATAPI errors listed in the System log with drive access - run CHDSK on all of them, even if it has to do it on a reboot - so there are no drives errors.

to eliminate any possible network issue, keep the LAN cable or Wi-Fi disconnected.

hmm... tried the ubcd, couldn't load my hard drives. RAM tests: fine. CPU stress tests: great. Nvidia gpu memory: couldn't complete, fail in loading a module...

hence I'm concluding in one of the following:
a) its the gpu
b) its the solid state... (think it's more likely...)

(oh, forgot to mention that in an effort to "solve" the problem I purchased the new psu and changed aaaaaaaall the cable ;) )

About the network... I've tried it a couple time unplugged.

wish me luck with the BIOS upgrade ;)

Bios upgrade made things a bit better, now it's just slow, I'm assuming due to the low RAM, I will try to see tomorrow how the system behaves if I remove the graphics card.
So apart from the BIOS update, one of the 2 should solve my problem: i) low RAM ii) GPU memory problem...

Thank you!
