Fourteen years of assembling, repairing and upgrading computers for homes, studios, schools and enterprises across West Bengal.
CompuCore Systems began as a small counter in the bustling computer market of Kolkata and has grown into a full-service destination for computer hardware and components. From our service centre in Kolkata we supply processors, motherboards, graphics cards, memory modules, storage drives, power supplies, cabinets, monitors and peripherals to customers across West Bengal and beyond. Every product that leaves our shelf is checked, serial-verified and backed by the manufacturer's official warranty.
Our team of certified hardware engineers specialises in custom desktop assembly. Whether you need a budget-friendly study PC, a silent office workstation, a colour-accurate editing machine or a high-refresh gaming rig, we map your workload to the right chipset, socket and power envelope. Nothing is over-sold and nothing is under-specified — you get a build sheet that explains every single component choice before a single screw is tightened.
Beyond sales, CompuCore Systems runs a busy repair and upgrade desk in Kolkata. Cracked laptop screens, failing hard drives, dead SMPS units, overheating GPUs, corrupted BIOS chips and slow boot times are diagnosed in-house using professional testing equipment. We publish transparent estimates, use only genuine spare parts, and return most upgrades within the same working day so your downtime stays minimal.
We also serve institutions. Schools, coaching centres, co-working spaces and corporate offices across Kolkata rely on our annual maintenance contracts, bulk procurement support and on-site troubleshooting. Dedicated account managers keep spare inventory ready for our AMC clients, which means hardware failures get resolved in hours rather than weeks — even during peak examination or audit season.
What truly separates us is after-sales care. Free basic installation guidance, remote driver support, upgrade counselling and a genuine RMA handling desk are included with every purchase. Customers from Salt Lake, Howrah, Behala, New Town, Park Street and Barrackpore keep coming back because we treat a ₹2,000 RAM stick with the same attention as a ₹2,00,000 workstation. That consistency is the reason CompuCore Systems is recommended across Kolkata's technology community.

Real feedback from students, professionals, gamers and business owners we have served.
"I ordered a custom editing workstation and the build quality genuinely surprised me. The cable management was spotless and the render times dropped by more than half compared to my old desktop."
"My laptop had become painfully slow. They upgraded the RAM and installed an NVMe drive in under two hours. It now boots in seconds and handles all my accounting software without freezing."
"We purchased thirty desktops for our coaching centre. Delivery was on schedule, every unit was labelled and the invoicing was perfectly clean. Their AMC response time is genuinely quick."
"My graphics card died during a project deadline. They diagnosed it the same evening, arranged a replacement under warranty and kept my work running. That kind of support is rare."
"I knew nothing about components and was worried about being overcharged. They explained every part, gave me a written quotation and stuck to it. My gaming PC runs beautifully."
"Their team replaced the SMPS across our entire office floor after repeated power issues. Since then we have had zero unexpected shutdowns. Professional diagnosis and fair pricing."
