Hi, thanks in advance for helping.
Computer MSI Motherboard FM2 chipset, AMD Athlon (Trinity Core) X4 740 Quad ore, 8 G of ram.
Window 7 64 Bit.
Internet Connection Wireless AC PCI card.
I use it mainly streaming blu-ray, watching TV, surf net and do little work from home (nothing heavy).
The computer was getting slower, open up chrome, CPU usage spike up to 70%, watching TV (WMC) and surf the net with couple open pages with flash, CPU usage stay around 90%.
The internet speed is also getting slower around 12 mpbs., file transfer between my 2 other computer was around 20 mbps. My other computer in the living room, similar spec is getting 30 mpbs internet and 100 mbps on file transfer.
I have spybot and also give avast a try. Now giving AVG a turn and only couple adware/malwares show up.
Been checking on NT Kernel and System high usage constantly staying at 20 to 30.
Running Processor Explorer on it , it show ntoskrnl.exe!NtShutdownSystem+Ox1e580 and ntoskrnl!KereleaseInStackQueuedSpinLock+0x1e0 using a lot of CPU power.
Please let me know what other information you need.
