Windows 7: svchost.exe using 100% of CPU & BIOS update error message

svchost.exe using 100% of CPU & BIOS update error message

Dell Vostro 1510 laptop with Windows 7 Pro 64bit.

I noticed svchost.exe was using 100% of CPU.

I did the following that did NOTresolve the issue:

1. I installed a new hard drive (W7)

2. I went to task manager / processes / "show processes from all users" / and attempted to stop all the related services, approximately 8. 4 of them stopped and no improvement. The other 4 would not let me stop them.

3. I've been reading Dell, and several other related sites, found many causes/solutions, tried them all but haven't resolved it.

4. I removed fan and cleaned out all dust. Fan runs fine. Thermal paste is good.

5. Installed CPUID HW MONITOR and cpu is not running hot. it's at 76 celsius (67 - 85 is the acceptable range)

6. Ran malwarebytes, custom scan. Nothing found.

7. Ran Avast boot time scan, nothing found.

*** The strangest thing is that my Bios version is A12. I downloaded A13 and A15 from When I attempt the Bios flash I get an error message that the "winphlash sw tool by phoenix tech cannot load driver. This driver has been blocked error code 1275. Confirm you have administrator priveledges". ***

- Therefore, is there a glitch/virus in the Bios causing this? Or is it unrelated and something else is causing it?

Thanks in advance!
