Windows 7: Windows 7 - lot of problems

Hello,

I have a new PC with the following configuration. any USB device (except mouse and keyboard) is not recognised (e.g. external hard disks, flash memory, iphone, camera, etc.)
Tried several solutions; like changing the usb port, switching off the pc power, updating the windows. Nothing works.

ALso; when I use 3D graphic applications, like imvu, or 3D games (like battle realms) the program starts and runs for sometime; then the pc restarts (it shows the blue screen). My graphics card is nvidia geforce 400 Series GTX 480. The graphics card is 1.0 GB

Intel Core 2 Quad CPU, 4.00 GB RAM (3.00 USABLE), 32-bit operating System windows 7 Home Basic (Genuine). Directx is 11

Any help will be really appreciated.

Regards,

Sherif

I suspect power supply... GTX 480 gobbles power like a river... anyway, fill out your system spec, down to the last detail (every detail counts, make/model numbers, specs, everything). More info = better view of your problem.

I filled the specifications.

Thanks and regards,

You didn't provide any specs for your PSU. That's kinda' important considering the graphics card your currently running.

It could be a few other things too. RAM, or GFX card not properly seated [causing the BSOD's]. USB controller driver needs updated. USB controller isn't enabled in BIOS. Not enough clean power from PSU.

Most likely your problem is one, or more, of the above.

I checked the USB drivers and found them all the default Microsoft dated to 2006
I think they need update to work in windows7
Windows update did not mention anything about them.
I will keep on updating here
thanks

You still havent said what PSU you have...

I am trying to find any tool which can detect the PSU brand.
I found sme tools like 'Everest' and CPU-Z which can detect som features, including the wattage of the power supply. Any recommendation for a tool which can detect the PSU?
Thanks

You'll need to open the case... but DO NOT do it if your pc is still under warranty period. Remember to turn it off and to unplug it before open the case.

Let us see the results!!!

I don't think I've seen ANY software(s) that can identify power supply(s)... You need to go and open your case, and look - then write back to us...
