Acer Aspire One D 270 is slow; My Acer pc so slow!
Some Acer PC, i.e. Aspire One D 270, are very slow sometimes. It acts as unusable. The scenario is like this – the start time is 15 minutes, and the shutdown time is 7 minutes.
In this article, we will find out all the best possible ways to speed up your slow PC and make it as fast as it was before!
Solution-1: Checking The RAM physically.

- Is there full 4 GB RAM installed in your system?
- If not, though you have 4 GB of RAM, see how much RAM is installed.
- Is it 2 GB RAM showing instead of 4 GB?
- If 2 GB RAM shows instead of 4 GB, “This is the cause of slowing down your computer”.
- Immediately change or remove the dead RAM from the slot.

Generally, a laptop or notebook has two RAM slots. Check the dead RAM and remove it for better performance.
Solution-2: Change your HDD SATA mode to AHCI
There are three types of SATA mode in your BIOS settings. IDE, AHCI, and RAID are them. IDE is the older mode with limited functionality. It was made for old operating systems like Windows XP.
On the other hand, AHCI is compatible with Windows latest versions like Windows 7, 8, or 8.1. Rather than IDE, AHCI reduces the time to save and open files on the hard drive via the native command queuing (NCQ) feature.

Selecting the AHCI mode should solve the “Acer PC so slow” problem.
Solution-3: Update your graphics driver.
Every laptop or notebook has its specific display resolution. It comes with particular display hardware. If the display device doesn’t have the right driver, it can’t perform correctly. It is important to update all your drivers, including the display adapter.
To update your driver according to your device, I personally recommend you to download “Driver Genius” software from Amazon. It is enough to update all of your drivers. Once you have downloaded the software, Install it and find the “Out Dated” drivers.
You may also use Driver Max for a continuous PC driver automatic updater.

Solution-4: Remove viruses and malware.
You may have been the victim of a virus or malware. If the above method does not work, please check your whole PC with paid antivirus software.
- Kaspersky Internet Security- For Virus Protection.
- Malwarebytes Antimalware- For Malware protection.

Though there are many antivirus software in the market, I personally fan of Malwarebytes. Its malware detection is beyond questions. To remove malware that fails almost every antivirus or internet security, you can trust this version.

Solution-5: Change Your HDD to SSD
One of the main reasons for “Acer PC so slow” is the hard disk drive and its speed (RPM). for a faster computer operation, it is strongly recommended to use the “Solid State Drive (SSD).” An SSD with a large storage size can save time by increasing tremendous speed.

Solution-6: Increase virtual RAM
You can use your HDD or SSD as RAM. If you lack RAM, you can use your hard disk or solid-state drive to solve the “Acer PC so slow” problem.
