Razer is a well-known brand among PC gamers and users, it started as a peripheral manufacturer focused on keyboards and mouse but after years passed Razer expanded its inventory offerings. It soon started offering headphones and lately has branched into wider product lines like gaming chairs and protection masks. It is not a big surprise that Razer is expanding into other branches of the PC industry. This time, however, it has revealed not one but three new hardware for your PC. Case fans, all in one liquid cooler and power supply. There are not many details about the products themselves but one thing is one hundred percent confirmed, they come with Razer Chroma, all of them, even the fans.

Katana Chroma ATX PSU

Most interesting for me personally is Razers Katana, the power supply unit. It is a modular power supply ranging from 750W to 1200W with the additional option of Titanium rated one with an impressive 1600W of power. Power supply will start shipping in early 2022 and at the time of writing this article no price range has been released.

Razer Hanbo AIO

Hanbo liquid cooler will feature an optimized intake design so it can ensure greater heat transfer and fluid dynamic for improved reliability and silent operation. Radiator comes in 240mm size with two fans and a larger one of 360mm with three fans. The pump will be able to rotate in any direction of full 360 degrees so it can fit in any case. Hanbo will be released in November this year but no pricing has been released so far.

Razer Kunai Chroma case fans

Kunai fans will boast high static pressure performance with lowered noise. They will go as far as 2200rpm for the 120mm version where the 140mm version will go up to 1600rpm. They will come with addressable LEDs and up to eight fans will be able to be connected to Razer’s PWM fan controller that will come with a magnet at the back for easy attachment to any steel part of PC casing.

Fans are priced at $44.99 for one 120mm or $129.99 for a three-pack of 120mm. One 140mm will go for $49.99 and a three-pack will be $129.99.

Error Code 36 – What is it?

This is a common Device Manager Error Code that users encounter. It is commonly found on all Windows 2000 and later versions of Windows operating systems. Error Code 36 is usually prompted by the following message:

"This device is requesting a PCI interrupt but is configured for an ISA interrupt (or vice versa). Please use the computer's system setup program to reconfigure the interrupt for this device. (Code 36)"

Solution

Error Causes

Error Code 36 occurs when there is a failure in IRQ translation due to your Windows operating system getting corrupted. This is caused due to a number of triggers, such as:

• An excess of startup entries
• Errors in registries
• RAM or hardware failure
• Excessive unnecessary installed programs
• Malware or spyware

When programs are removed excessively, some programs are not removed completely and create problems in your computer’s registry.

Also, due to the presence of malware and spyware and other causes mentioned above, your computer registry builds up errors with the time that leads to slowing your PC, time lags, and even result in crashes and freezes.

Error Code 36 can cause internal and external components to malfunction or experience time lags such as DVD drive or printer and hence can severely affect your entire PC.

Further Information and Manual Repair

Error Code 36 is a severe PC error and any attempt at fixing the error must be approached with extreme caution for your PC to start functioning properly again. Here are two methods to fixing your PC.

Method 1 – Change IRQ reservation settings

Changing the IRQ reservation settings is the best way you can rely on to fix the error code. You can do this by changing the BIOS settings of your PC.

The BIOS stands for ‘Basic Input/Output System’ and is the program of your PC’s microprocessor that allows your PC to boot after you switch it on.

Caution needs to be exercised before changing the BIOS settings of your PC. This is because every PC’s BIOS version differs from another and any wrong attempt to change the settings may make matters worse.

It is therefore recommended to refer to hardware documentation that you received with your PC or motherboard and check for the model number and details of your PC’s motherboard.

Only after you have checked and confirmed all the details, should you use the specific BIOS settings required to configure your IRQ reservations?

Method 2 – Install DriverFIX

Error Code 36 isn’t an easy error to remove.

While changing the BIOS settings can work to restore your PC, it may create a whole lot of inconvenience for finding the time and effort to check the hardware documentation details and attempting to change the specific settings and especially, if your PC does not support the options to change IRQ reservations.

Given the high risks of fixing such an error, you can also install software that enables you to fix your slow PC at the click of a few buttons.

Programs such as DriverFIX can enable you to download and replace your outdated drivers with new updated ones without you having to look for them. It will detect which drivers to download based on your PC’s motherboard version from the program’s database and can get rid of error code 36.

Click here to download DriverFIX and remove error code 36 and any other type of Device Manager error from your PC.
