Gaming PC Repair & Upgrade

Gaming PCs are our home turf: at Comp Master in Ashdod we repair, upgrade, build and maintain gaming computers — from streaming setups to 4K machines. Dropping FPS, mid-game freezes, overheating or a graphics card drawing artifacts — these are problems we solve every week, with dedicated diagnostic equipment and original parts in stock.

What do gamers come to us with?

1. FPS has dropped — games that ran smoothly now stutter
2. Freezes and micro-stutters in the middle of a game
3. The PC sounds like a jet and runs hot — sometimes shutting down under load
4. Artifacts on screen: stripes, squares, weird colors — a graphics card in trouble
5. Blue screens (BSOD) that appear specifically in games
6. You want more power: a GPU, CPU or RAM upgrade

What we do with gaming PCs

• Diagnostics under load — we run real stress tests (GPU, CPU, memory, PSU) and pinpoint exactly what is choking the system
• Graphics card repair — artifacts, driver crashes, stuck fans; prices in the table below
• Smart upgrades — GPU, CPU, RAM and NVMe SSD, with compatibility checks against your PSU and motherboard. See also upgrades for desktop computers
• Cooling — AIO liquid cooler replacement, fans and thermal paste, better case airflow
• Cleaning and maintenance — dust is the number one enemy of stable performance
• Building a new gaming PC — to your budget and goals, details on the building a new desktop page

Overheating: the #1 cause of lost performance

Dust in the radiators, old thermal paste and weak airflow lead to thermal throttling — the CPU and GPU slow themselves down to survive, and your FPS dives. A thorough cleaning plus fresh paste brings performance and silence back. And when a liquid cooler ages or leaks — we replace it quickly.

An upgrade you can feel: what actually raises FPS?

In most cases the graphics card is the key — but not always. A weak CPU bottlenecks a strong GPU, slow RAM causes micro-stutters, and a mechanical drive drags loading times. During diagnostics we find the real bottleneck, recommend an upgrade that fits your PSU and motherboard — and never sell you what you don’t need. After installation: a full stress test, driver updates and tuning, so your PC comes back game-ready. Here is a fresh RTX 5090 upgrade from our YouTube channel:

Gaming PC — FAQ

How much does a gaming PC repair or upgrade cost?

It depends on the component and the fault: prices for graphics card repair and cooling system replacement are in the tables below. Full diagnostics under load — and the final quote before any work.

I see artifacts on screen — is my graphics card dead?

Not necessarily. Sometimes it is overheating, video memory or solder issues that can be repaired. Bring it in for diagnostics — we will tell you honestly whether a repair makes sense or an upgrade is the better call.

How often should thermal paste and cleaning be done?

For a hard-working gaming PC — cleaning and fresh paste every 1–2 years. If temperatures have crept up or the fans are louder than they used to be, it is time.

Liquid cooling or air cooling?

For most configurations a quality air cooler is more than enough. Liquid cooling (AIO) is worth it for hot CPUs and compact cases — as long as it is maintained. We will match the solution to your CPU, case and budget.

My PC is old — can I just swap in a new graphics card?

It depends on your PSU, CPU and motherboard. Sometimes a GPU-only upgrade gives a great jump; sometimes it gets bottlenecked. During diagnostics we will check your setup and tell you honestly what gives the best value — a targeted upgrade or a new build.

We repair, upgrade and build gaming PCs in Ashdod — from the graphics card to liquid cooling, on average within about 3 working days (express out-of-queue repair is available for a surcharge). You can browse gaming PC components and ready-built systems in our store compshop.co.il.
