I have a DV7 4295us. it has a Sandy Bridge I7 Second gen 8 core. 6570 graphics 8 gigs of ram 1 ter HDD. I have had the Laptop for about a month and the HDD goes out. No prob, stuff happens, I called they sent me a new one really fast. I installed it and reinstalled the operating system, reloaded my games and every one of them lagged now. Not before. i looked at the Win Index andn the CPU droped from I think 7.3 to 5.3, why. All the other components are the same. I cant think of anyway that a HDD has anything to do with a CPU. So anyone have any ideas? HP has been useless, I paid 300 bucks for the extended in house warrenty and they do nothing. It is really ticking me off. Anyway, why the drop? Anyone? I did reinstall it again on the bad hard drive and it went down to 5. What are they up to?
Sorry it is 8 threads 4 core Whatever, well anyway i fixed it. i ran Norton Deep Scan and now the numbers are back. 7.4 on the CPU and 7.6 on the memory. Nothing lags anymore. Yes i installed all the drivers.
I ran an intel program on it and it says it does not supprt FSB but it has a bus speed of 100. i am really confused about this. Anyone shed some light for me. I have built many Desktops for people and myself. Never before have i had a laptop. This is all new to me, i know heat is a problem with notebooks. Please any info? Dont be a $#@$ like the others please. "Ohh you gotta an 8 core they dont make them", that does not help my problem.
Deep Scan Found a MALWARE taking up CPU time. Duh! Sorry but you really need to think a little.
If you failed to use Microsoft Security Essentials which is FREEEEEEEE, or regularly scan with Malwarebytes which is also FREEEEEEE or the dreaded Norton that you already own, then you need to think a little.
