Well its plenty of processing power with a quad core i7 for most anything you might be doing. What version of
Windows? If it was ordered with 8GB of RAM then hopefully Toshiba was smart enough to load 64 bit whether
Windows 7 or 8.
The Intel HD 4600 graphics "might" be an issue. Unfortunately there is not much of anything you can do about that - it actually does not even have 64MB. 64MB is the minimum that the system dynamically assigns from the system memory and supposedly will dynamically assign up to around 1.5GB as needed.
The hard drive "might" be very slow depending on the specific model (you could find that out in device manager) or it might be a decent one. The "value" lines of laptops almost always come with the slowest 5400 rpm hard drives with an anemic tiny cache. Faster ones will be 7200 rpm, and of course the best will be an SSD (Solid State Drive) which are getting quite inexpensive now. For example an excellent SSD is the Samsung 850 EVO which is $162 for a 500GB one on Amazon. You would also need an "ssd transfer kit" to make upgrading to one super simple and easy.
Ram - 8GB is not bad but if the machine is being used for design and as the RIP and whatnot I'd see if it could be upgraded to 16GB.
As I had mentioned it could be any number of things though, even a bad memory chip. A bad memory chip on a stick of ram will not always make a system crash - that particular address of memory might only rarely get used which can make it hard to diagnose.
If it were me, I'd attack it in this order. I'd check for a BIOS update from Toshiba. Then update certain key system drivers like the Intel HD video, Intel Chipset Drivers, and network drivers. I'd also check the
Windows system paging file settings to make sure its not set to some small fixed amount or something. I'd make sure any antivirus software is not interfering with Flexi. Next I'd download and install Priform CCleaner (its free) and let that cleanout all the temp clutter files, then let CCLeaner clean up your registry (run this part a few times until it finds no issues), then still using CCLeaner under Tools>Startup disable any useless crap that is starting up automatically. I have used CCleaner literally on hundreds of systems and never once has the recommended registry fixes given me any problems. It has only ever helped and improved things.
Finally I'd move onto the hardware. The single most significant upgrade you can do will be the hard drive. I'd do whatever I could to get a 500GB SSD to upgrade the hard drive. Moving from a mechanical hard drive, especially if its a slower 5400 RPM one, the difference an SSD will make to the machine will literally be stunning. An SSD will also significantly increase battery life for when you are mobile. Next thing for me would be to see if the machine can accept more ram taking it up to 16GB.
