I have recently built new gaming computer for my son. the computer instillation went flawlessly and started up and ran slow and "laggy" thru start up multitasking. games ran fine after they were slowly loaded up though we were getting random freezes here and there. the instillation included a Crucial V4 128GB SATA II MLC. the first install i forgot to enable TRIM and ACHI mode. So i reran the instillation with all that enabled and no dice. windows performance index says the hard drive is 6.9 out of 7.9 which is a little slower than expected. i disabled page filing and indexing. ANY HELP WILL BE GREATLY APPRECIATED
