Dårlig cpu performance

Har haft min maskine i lidt over et års tid, som er en selv-byg maskine. Men pludselig er cpu'en gået hen at blive mærkelig, da den performer virkelig dårligt i forhold til førhen.

Lagde mærke til problemet ved at kører windows experience index. Her scorer min Core i7 860 2.8 processor kun 4.3 og er dermed lowest scorer. Mener at den førhen har været omkring de 7 i indexet.

Tænkte så, at jeg nok ikke kan stole på windows experience indexet, så ville lave en benchmark test. Brugte performancetest 7.0. Her scorer min cpu 2163.2 hvor på passmarks hjemmeside skulle den have 5585. Altså igen er der noget der typer dårlig performance.

Maskinen er nyformateret da jeg havde lidt problemer med min ssd disk som jeg nu har sendt til rep.

Øvrie specs.

8 Gb ddr 3 Kingston ram 1333 Mhz
STRØMFORSYNING 750W THERMALTAKE TOUGHPOWER CABLE
VGA PCI-E 1 GB RADEON HD 5770 XFX GDDR5
MB ASUS P7H55-VIntel H55 Express / ATX / 0CPU
KABINET Thermaltake Element G.

Umiddelbart kan jeg ikke mærke problemet som sådan. Dog er core temp på over de 80 grader. Har ellers tjekket for skidt i fanen, men er næsten komplet ren da det ikke er længe siden den ik et blæs.

Nogen gode ideer guys? Evt nogle data i vil have eller noget i den dur?

Kan bare ikke finde ud af hvad der er galt. Har endda installeret nyeste bios og drivere. Og prøvet intels diagonse program.
