New computer.. AMD FX9590 black edition, 8 cores, 4.71 Ghz, DeepCool Assassin II cpu tower cooler, 8GB 1600, Corsair Dominator RAM, MSI Radeon RX 470 4GB video card, PNY 120 SSD boot drive and 2 data hard drives a 3tb and 1.5tb which should be sufficient storage.. Case: is a Cooler Master Masterbox 5t and the power supply is a EVGA SuperNOVA 750 G2 80+ GOLD 750W modular.

This system runs flawlessly, but cannot be put in a confined space and needs room to breathe.. So can't be used under a desk in a cubby hole. Testing is with Far Cry 5 at 1080p and runs perfect.

Price is $750

This is the old computer.. AMD Phenom II 1090T X6 6 core 3.2 Ghz 120tdp, Arctic Cooling Freezer XTREME cpu cooling tower, 12GB of Ripjaw 1600 RAM, MSI Radeon RX 470 4GB video card, and 2 small hard drives and a BluRay DVD burner.. It runs really well and I have no complaints.. It's for sale currently without the Bluray, but has a new Lightscribe DVDRW in it.. for $400 which is a steal.. I have other cases and parts to choose from. Similar case would be free..

The new system build is chugging along. The assassin 2 cooler is massive and so pulling the motherboard was no surprise.. The documentation on the cooler was wrong for the AMD 3+ chip 9590 that I installed. So had to guess on what looked correct to make it fit correctly..

The Assassin II Cooler, by Deep Cool, is a monster, had to adjust the front fan to clear the Corsair Dominator heatsinks. The front fan brushes the glass on my clear side panel of the case in height.

I still have much to do, pull the fans back off to adjust cabling towards the other side of the case. So this will take some time to get everything right again. Then have a 3TB and a 2TB hard drive to install, plus video card and Windows 7 - 64 bit on the 120gb ssd drive that's already installed.

Hope to finish it tonight so Far Cry 5 can be installed for tomorrows review.. Thank you fir reading.

Tomorrow's the big day!! Starting the AMD 9590 build below, finally received all the parts I needed to begin.. Will keep you posted on how it performs and how the build looks completed..

New system to build and test. This system has been judged as a do not buy on Tom's Hardware because of performance and processor heat. I'm here to prove them wrong..

The CPU I am using is the dreaded AMD FX-9590 Black edition Vishera (Bulldozer). The reason it is dreaded is due to the 220W TDP rating of this chip. It runs extremely hot at 4.7ghz stock speed and can be overclocked to around 5.1ghz. It has a turbo of 5ghz but that is only with 1 or 2 of the eight cores being used. With that in mind, I'm going to shoot for an overclock of 5.1ghz stable with no water cooling.

The motherboard of choice is an Asus Crosshair V Formula Z, which is design to handle the 220w TDP processor.

Keeping it cool is the DEEPCOOL GamerStorm ASSASSIN II-CPU Cooler with 120mm and 140mm fans. This tower cooler is huge, just delivered today, so I can get started building..

RAM -- Corsair Dominator 1600mhz 4 x 2gb sticks
Video - MSI RX-470 4gb ddr5 (replacing next month with a GTX 1070 8gb card)
Hard drive - PNY 120gb SSD for booting
Case: Cooler Master Masterbox 5t
Power Supply: EVGA SuperNOVA 750 G2 80+ GOLD 750W

There are too many discrepancies online about the 9590 and what it can and cannot do. Most of the negativity comes from people who don't even own or have owned this chip. Well I'm here to set the record straight and give an unbiased review of the processor, good or bad..

Thank you for reading and stay tuned for the results later this week..

Have started a new project, Data Mining and building systems to mine crypto currencies.. The GPU mining business is expensive to get into, but not impossible.. For under $1500 you can get an 8 GPU mining rig..

Hi all.. been a while, had a system crash, processor died on me, but it gave me a chance to look at a computer that was given to me.. The computer was presumed trash and was tossed only to be revived by me and a few parts from my old system that bombed out..

The scrap system consisted of a Asus CrossHair IV ROG board with a 1090T AMD Phenom II processor, 250 and 500 GB hard drives and 4GB of Ripjaw RAM.. There was no power supply or heat sink on the processor..

So for the heck of it, I scavenged some parts from the FX 8350 build, Arctic Cooler, 8GB more of Ripjaw, Corsair Power supply, Blue Ray burner and the MSI RX470 4G video card..

After clearing the bios and playing around with the board a bit, it roared to life and the system is running stable and is surprisingly fast for an older machine..

The Crosshair system board has tons of possibilities for over clocking and is a perfect fit for gaming.. Currently in Fallout 4 running 100 + mods it is cruising with no problems on ultra settings.. Mostly due to the RX470 but all in all has bought me some time to think about my next gamer build as I have time now to buy the parts I want to build the new machine..

Currently on this box I have 2.75 TB internal and 17TB external for hard drive storage.. Hope it's enough.. lol

Thank you for reading, and if I get some wire management in this case I will take some pics..

Problem sharing files on Win 98 - Windows XP machines with Windows 7 - 10 The problem..........

The problem is Windows 7 and above uses NTLM version 2 (NTLMv2) authentication. By default, NTLMv2 authentication is not enabled in Windows 2000 or in Windows 98. Therefore, this issue occurs.

The Solution...........

Enable NTLMv2 authentication on the Windows 2000- or the Windows 98-based computer. To do this, follow these steps:

I found you need to perform this on the older OS computer and the newer OS machine.. Otherwise, when you attempt to connect to the shared folder on the older system you will get access issues..

I was able to share a drive on a Windows 2000 Pro machine and able to access it using my Windows 10 OS machine by following these steps:

1. Start Registry Editor. To do this, click Start, click Run, type Regedit, and then press ENTER.
2. Locate and then click following registry subkey:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\LSA
3. Locate the LmCompatibilityLevel registry value.

If the registry value is not present, follow these steps to create it:
1. Select the registry subkey that is listed in step 2.
2. On the Edit menu, point to New, and then click DWORD Value.
3. Type LmCompatibilityLevel, and then press ENTER.
4. Set the DWORD value to 1. To do this, click Modify on the Edit menu, type 1 in the Value data box, and then click OK.
5. Exit Registry Editor, and then restart the computer.

I hope this helps anyone else having the same issue...

The new cover pic is a water cooled PC built into a glass top computer table.. Pretty ingenious idea.. I believe my next build is going to be in a corner table and the system will be built into the hutch with a plexiglass front.. That way I could add the Thermaltake Big Water on a shelf above the PC and run all the lines to the clear fronted case below..
