It's probably the Vertex. I have the same one and OCZ released a firmware update on Monday. If you don't hsve firmware version 2.15 and are using version 2.11 or prior, you nedd to get the new version. Apparently all Sand Force 22** series ssd's are having issue's with freezes, bsod's, etc. OCZ was the first to put a firmware update out, as they're also the first company to put a SF 22** ssd on the market. The other ssd companies will be putting out firmware update's, if they haven't already. Bad news is If you don't have a 2nd or even third hard drive, you're going to have trouble's. OCZ's sata 3 ssd's can't have their firmware flashed while being the boot drive. I personall have 2 Caviar Black's and was lucky the firmware update appeared after my weekly backup/system image. I moved my Document's, Downloads and Contacts from my 1st Caviar Black to the 2nd Caviar Black which contains my multimedia files. I then formatted the 1st Caviar Black and put Windows 7 on it, just long enough to flash the firmware. I then restored my day before system image, moved the files I moved to the 2nd Caviar Black back to the 1st Cavair Black after reformatting it to get rid of Windows 7 on it. Activated Windows, updated security software and re-installed 3 program updates. Here's a link to a post on the forum about OCZ's firmware update. It has link to the firmware update. Try that first and see how it goes.
